React also recently released the React 19 beta version, which includes various new features.

Before building a production-ready React application, it’s important to avoid several anti-patterns while writing React. In this detailed blog, we will explore some of these anti-patterns in React and discuss how to write better code.

Without further ado, let’s get started

Props Drilling

One of the common errors that new React developers make is prop drilling. It is the process of passing props from the parent component to its child component.

Let’s take a look at this example:

import React, { useState } from “react”;

const Child = ({ increment }) => {

  return (

    <div>

      <button onClick={increment}>Increment</button>

    </div>

  );

};

const Parent = ({ increment }) => {

  return (

    <div>

      <Child increment={increment} />

    </div>

  );

};

const Grandparent = ({ increment }) => {

  return (

    <div>

      <Parent increment={increment} />

    </div>

  );

};

const App = () => {

  const [count, setCount] = useState(0);

  const increment = () => {

    setCount(count + 1);

  };

  return (

    <div>

      <Grandparent increment={increment} />

      <div>Count: {count}</div>

    </div>

  );

};

export default App;

Here you can see that the increment function is passed down through multiple layers of components just to be used in the Child component. If the application grows in size or there are more components between App and Child, this prop drilling pattern will result in a lot of redundant code, making it more difficult to maintain.

Prop drilling becomes a problem when you have to pass props through several intermediary components that don’t actually use the props themselves, but just serve as messengers to pass them down further. This can make the code harder to maintain and understand especially as the application grows larger.

To reduce prop drilling, you can use techniques like React’s Context API or state management libraries such as Redux. These tools allow you to manage and access global data without having to pass props manually through every level of the component tree.

Using Index as Key

Using the index of an array as a key in React is a common anti-pattern that developers should avoid.  

React uses keys to identify elements in a list and then track changes efficiently during updates. When you use the index as the key, React doesn’t have a stable identifier for all the items. If the order of the items changes or if items are added or removed, React may re-render more items than necessary, leading to potential performance issues.

Bad approach

import React from ‘react’;

const ListItems = () => {

  const items = [‘Apple’, ‘Banana’, ‘Orange’];

  return (

    <ul>

      {items.map((item, index) => (

        <li key={index}>{item}</li>

      ))}

    </ul>

  );

};

export default ListItems;

Here we are using the index of each item in the array as the key prop for the list of items. While this may seem convenient, it can lead to problems, mainly when the list is dynamic and items can be added, removed, or reordered.

Better approach

import React from ‘react’;

const ListItems = () => {

  const items = [

    { id: 1, name: ‘Apple’ },

    { id: 2, name: ‘Banana’ },

    { id: 3, name: ‘Orange’ }

  ];

  return (

    <ul>

      {items.map((item) => (

        <li key={item.id}>{item.name}</li>

      ))}

    </ul>

  );

};

export default ListItems;

To avoid using the index as the key, developers can use unique identifiers associated with each list item, such as database IDs or other unique attributes. Using unique identifiers ensures that each list item has a stable identity, even if the list order changes or items are added or removed

Modifying the Component state directly

Modifying the state directly in React is considered an anti-pattern. When you modify the state directly, React doesn’t detect the change, which can lead to unexpected behaviour in your application’s rendering. React relies on the setState function to properly trigger re-renders when state changes occur.

State updates in React are asynchronous, meaning React batches multiple state updates for performance reasons. When you modify the state directly, you risk introducing race conditions and inconsistent state updates, as React won’t be able to properly batch and synchronize the updates.

Example

import React, { useState } from “react”;

const Counter = () => {

  const [count, setCount] = useState(0);

  const increment = () => {

    // Modifying state directly (bad practice)

    count++; // Incorrect way to update state

    setCount(count); // Updating state using setState

  };

  return (

    <div>

      <p>Count: {count}</p>

      <button onClick={increment}>Increment</button>

    </div>

  );

};

export default Counter;

To avoid the mutable state anti-pattern, always use the setState function to update the state in React components. This ensures that React can properly track state changes and trigger re-renders as needed.

Not Using the useCallback Hook When It Would Be Beneficial

The React useCallback Hook returns a memoized callback function that helps to improve the performance of your code. Not using the useCallback hook when it can be done is indeed an anti-pattern in React.

Functions declared inside functional components are re-created on every render. When these functions are passed down to child components as props, it can lead to unnecessary re-renders of those child components. By using useCallback, you can memoize the function so that it’s only re-created when its dependencies change, reducing unnecessary re-renders.

Here is a simple example:

In the code, we have two parent components:

With useCallback()

const ParentWithCallback = () => {

    const [value, setValue] = useState(“”);

    const callback = useCallback(() => {

      console.log(“Operation performed with useCallback”);

    }, []);

    return (

      <div>

        <ChildComponent callback={callback} />

        <input

          value={value}

          placeholder=“Type here (with useCallback)”

          onChange={(e) => setValue(e.target.value)}

        />

      </div>

    );

  };

Without useCallback()

const ParentWithoutCallback = () => {

    const [value, setValue] = useState(“”);

    const callback = () => {

      console.log(“Operation performed without useCallback”);

    };

    return (

      <div>

        <ChildComponent callback={callback} />

        <input

          value={value}

          placeholder=“Type here (without useCallback)”

          onChange={(e) => setValue(e.target.value)}

        />

      </div>

    );

  };

The one without the useCallback hook has a simple callback function, which will rerender on each state change as a new reference to the function is created on each render. This can lead to unnecessary re-renders of ChildComponent, even when ParentWithoutCallback re-renders due to state changes.

The component with the useCallback hook is much better in terms of performance. The function reference remains stable across renders as long as the dependencies array (second argument of useCallback) remains unchanged. Since the callback has no dependencies in this example, it only gets created once and keeps the same reference across renders.

Spreading props directly onto DOM elements

Spreading props directly onto DOM elements can indeed lead to the addition of unknown HTML attributes

Let’s take an example:

const Sample = () => (

    <Spread flag={true} className=“content” />

  );

  const Spread = (props) => (

    <div {…props}>Test</div>

  );

 The Spread component is spreading all props (flag and className) onto the <div> element without filtering them. And we know that <div> has no attribute called flag in its definition

If any unrecognised HTML attributes are included in the props passed to Spread, they will be added to the rendered DOM element. This can lead to unexpected behaviour or errors, as unknown HTML attributes may not be handled correctly by React or the browser.

The better approach is to create props specifically for the DOM attribute

const Sample = () => (

    <Spread flag={true} domProps={{className: “content”}} />

  );

  const Spread = (props) => (

    <div {…props.domProps}>Test</div>

  );

In this approach, the domProps prop is specifically used for passing DOM attributes, such as className. By spreading only domProps onto the div element, we ensure that only recognized HTML attributes are included in the rendered output.

Props Plowing

Props plowing can occur when components have a large number of props that need to be passed down to child components. This can lead to repetitive and verbose code, making it harder to maintain and understand.

const data = {

    id: 11,

    name: Adarsh Gupta,

    age: 20,

    avatar: “”,

    bio: “Student from Maths Department”

   }

   <StudentData id={data.id} name={data.name} age={data.age} avatar={data.avatar} bio={data.bio}/>

   <StudentData {…data}/>

Using spread operators (…props) can help remove this issue by reducing the amount of repetitive code needed to pass props down to child components. 

Avoid Deep Nested Callbacks

Nested callbacks, where functions are nested within each other, can make code harder to understand and maintain. Instead of having deeply nested callback functions, it’s better to break down complex logic into smaller, more manageable functions

Bad approach

const fetchDataApi = () => {

    fetchData().then((data) => {

      process(data).then((result) => {

        updateState(result);

      });

    });

  };

In this code, fetching data from an API, processing it, and updating the state are all nested within callback functions, making it difficult to follow the flow of the code.

Better approach

const fetchDataAndProcess = async () => {

    const data = await fetchData();

    const result = await process(data);

    updateState(result);

  };

Here, we have broken down the logic into separate functions: one for fetching and processing the data asynchronously using async/await, and another for updating the state. This approach makes the code easier to understand and maintain.

Wrapping it up

Thank you for taking the time to read this blog. You are a fantastic reader. 

In this detailed blog we have looked into several anti-patterns in React that are important to steer clear of in your next React project. These anti-patterns can introduce various performance issues into your codebase, which can ultimately impact the user experience and maintainability of your application.

Throughout the blog, we have not only identified these anti-patterns but have also provided insights into why they should be avoided. Now you can start to write some high quality React applications.

Keep learning!

The post Anti-patterns in React that You Should Avoid appeared first on Talent500 blog.

Sometimes you may sit and solve 1000+ Leetcode problems and still get stuck at some coding problems. The main problem is that candidates are having trouble understanding generic patterns. It is like a template that you can use to solve multiple questions.

In this article, we will walk you through some of the most asked coding interview question patterns with examples so that next time you get a clear idea when doing a question.

So let’s get started!

Sliding Window

The Sliding Window pattern is a technique used to work with a specific range of elements within an array or linked list. It’s handy for solving tasks like finding the longest subarray with certain characteristics, such as the longest sub-array problem.

Here’s how it works: You start with the first element and create a “window” of elements. This window shifts one step to the right at a time, and its size changes to match the problem you’re tackling. The window can stay the same size or expand and contract depending on what you need to achieve.

Here’s a basic outline of how the sliding window technique works:

• Initialize Pointers: Set up two pointers, usually representing the start and end of the window, at the beginning of the array.
• Adjust Window: Slide the window to the right by moving the end pointer. This represents including more elements in the window.
• Check Condition: Check if the current window satisfies a given condition or constraint. If it does, you can update your solution or perform other necessary actions.
• Adjust Window Further: If the condition is not satisfied, slide the window further to the right by moving the start pointer. This represents excluding elements from the window.
• Repeat: Continue sliding and adjusting the window until the entire array is covered or a solution is met.

Two pointer approach

These types of problems mostly deal with sorted lists (arrays or linked lists), and the goal is to find a set of elements that fulfil certain conditions. It involves using two pointers that traverse the array or list from different positions or directions to achieve a condition.

Here is the basic outline for the Two pointer approach 

• Initialization: Start with two pointers, usually set to different positions in the array or list.
• Traverse or Move: Depending on the problem, you move the pointers in specific ways. For example, you might move one pointer forward while the other moves backwards, or you might both move in the same direction.
• Comparison or Operation: At each step, you compare the elements pointed to by the two pointers or perform a specific operation based on the problem’s requirements.
• Adjustment of Pointers: Based on the comparison or operation, you might adjust the positions of the pointers. You can move both pointers, just one, or neither, depending on the situation.
• Repeat: Continue this process until the pointers meet, cross, or reach a certain condition, depending on the problem’s constraints.

Breadth-First Search

This approach draws inspiration from the Breadth First Search (BFS) algorithm used to traverse trees. It employs a queue to manage nodes at each level before progressing to the subsequent level. Any problem requiring a level-by-level traversal of a tree can be effectively tackled using this strategy.

This is how BFS works

• Initialization: Begin by enqueueing the root node onto a queue data structure.
• Iteration: While the queue is not empty, perform the following steps:
• Dequeue and Visit: Dequeue the front node from the queue. Process the dequeued node (based on the problem’s requirements).
• Enqueue Children: Enqueue all child nodes of the dequeued node onto the queue (if any exist).
• Repeat: Continue steps 3 and 4 until the queue becomes empty. This ensures each level of the tree is processed before moving to the next level.

Depth First Search

DFS, inspired by how we explore mazes, delves deeply into paths before backtracking. It’s like systematically searching through a drawer’s items. 

This method is effective for finding specific routes, searching, and understanding connections in structures. It can be done by either repeatedly exploring child paths using recursion, or by managing exploration steps manually with a stack.

By going deep first, DFS can uncover hidden solutions efficiently in complex situations.

How DFS Works:

• Initialization: Start with the root node or starting point.
• Explore and Visit: Explore as deeply as possible along a branch before backtracking. Visit the current node (based on the problem’s requirements).
• Recursion or Stack: Use recursion or a stack to manage the traversal.

If using recursion, recursively apply the same process to the child nodes.

• Repeat: Continue steps 2 and 3 until all nodes are visited or the desired condition is met

Binary Search

 Binary search is a clever algorithm used to find a specific value in a sorted list or array. It starts in the middle and checks if the desired value is higher or lower. Based on the result, it narrows down the search to the upper or lower half. This process continues until the target is found or the search range becomes empty.

This is how binary search works

• Initialization: Start with the entire sorted array or list and set two pointers, left and right, to the beginning and end respectively.
• Middle Element: Calculate the middle index between left and right. This is often done using the formula middle = (left + right) / 2.
• Comparison: Compare the value at the middle index with the target value you’re searching for.
• Three Possible Cases:

1. If the middle value is equal to the target, you’ve found the value and the search is successful.
2. If the middle value is less than the target, the target must be in the right half. Update left to middle + 1 to narrow the search to the right half.
3. If the middle value is greater than the target, the target must be in the left half. Update right to middle – 1 to narrow the search to the left half.

• Repeat: Continue steps 2-4 until left becomes greater than right. This means the search range is empty, and the target value isn’t in the array.

Top K elements

This pattern helps us find the top, smallest, or frequently occurring ‘K’ elements from a given collection of items. The best data structure for keeping track of ‘K’ elements is a heap. Think of it like special storage that helps us manage these ‘K’ elements effectively.

Here is the minimal workflow of this approach

• Initial Population: Start by placing the first ‘K’ elements into the heap. Depending on the problem, you might use a min-heap or max-heap.
• Iterate and Update: Go through the remaining elements. If you find an element that’s larger (for a max-heap) or smaller (for a min-heap) than the heap’s top element, swap them.
• Maintaining K Elements: Keep the heap’s size limited to ‘K’. If it goes beyond ‘K’, remove the smallest (for max-heap) or largest (for min-heap) element from the heap.

Subsets

Many coding interview challenges involve working with different arrangements and selections of elements from a set. Starting with an empty set, we will iterate through all numbers one-by-one, and add them to existing sets to create subsets.

Let’s take a simple problem and understand how it works:

The question is from Leetcode: Given an integer array nums of unique elements, return all possible subsets. The solution set must not contain duplicate subsets. Return the solution in any order.

Input: nums = [1,2,3]

Output: [[],[1],[2],[1,2],[3],[1,3],[2,3],[1,2,3]]

1. We will start with an empty set: [ [ ] ]
2. We will now add the first number to the set [ [] , [1] ]
3. Now add the second number(2) to all the elements inside the set [2],[1,2]] and add it to the original set [ [], [1],[2],[1,2] ]
4. Repeat the steps until all elements are traversed.

Here is a basic implementation of the above approach in JavaScript:

// Define a function called findallSubsets with a default array parameter sets.

function findallSubsets(sets = [1, 2, 3]) {

  // Create an initial subset containing an empty array.

  let subsets = [[]];

  // Loop through each element in the sets array.

  for (i = 0; i < sets.length; i++) {

    // Get the current element.

    let current = sets[i];

    // Store the current number of subsets.

    let lengthofSubset = subsets.length;

    // Loop through existing subsets.

    for (j = 0; j < lengthofSubset; j++) {

      // Create a new subset by adding the current element to an existing subset.

      // This creates a new subset for each existing subset.

      subsets.push([…subsets[j], current]);

    }

  }

  // Return the final array of subsets.

  return subsets;

}

// Call the findallSubsets function without passing any arguments.

// By default, it will use [1, 2, 3] as the input set.

findallSubsets();

Output 

While there are several other coding patterns that may be less frequently discussed compared to the aforementioned ones, if you’re interested in expanding your knowledge about these patterns, numerous free resources are available on the internet. These resources can provide you with further insights and guidance.

Wrapping it up

Thanks for taking the time to read about coding patterns for technical interviews. We’ve explored some really handy strategies that often come up during interviews. 

From Two Pointers to Sliding Window, and from BFS to DFS, we’ve broken down these techniques to help you understand how they work. By getting the hang of these patterns, you’ll be ready to tackle various coding challenges in interviews with more confidence.

 Good luck with your interview preparations!

The post Coding patterns for Technical interviews appeared first on Talent500 blog.

When diving into web development, you often start by setting up a project, which includes installing dependencies, configuring build tools, and creating essential files. Popular tools like Create React App (CRA) and Vite simplify this process.

But what if we told you there’s another way? In this blog, we explore the exciting realm of building a React app without relying on CRA or Vite.

CRA and Vite abstract the complex build configuration, allowing developers to concentrate on writing code and quickly building their applications. But I want to build these on my own, which is why this blog comes into the picture.

The primary purpose of this blog is to understand the fundamental principles behind development tools such as CRA and Vite, as they conceal various complexities from developers.

Web Bundlers

Web bundlers play a crucial role in modern web development by optimizing the delivery and performance of web applications.

They are tools that combine multiple files, such as JavaScript, CSS, and images, into a single bundle, which is then delivered to the browser. Some popular web bundlers include Parcel, Webpack, and others.

The main goals of web bundlers are

• Dependency management
• Code Organization
• Dependency Management
• Performance Optimization
• Code Splitting
• Compatibility and Browser Support, etc.

Why bundling a React app is essential

We can run a React application without bundling it, it is generally not recommended for production-ready applications. If we do not build our application, we may encounter several issues and limitations:

• Unoptimized code
• Lack of transpilation
• Missing dependencies
• Limited asset management
• No environment-specific configurations, etc.

While the bundling process ensures code optimization, compatibility, asset management, and environment-specific configurations.

It improves performance, reduces file sizes, and enables a smoother deployment process. Therefore, it’s essential to go through the build step to achieve the best results for your application.

The build process is essential for several reasons:

• Bundling
• Minification
• Transpilation
• Tree shaking
• Asset optimization
• Environment-specific configurations, etc.

Include necessary script tags into the project via CDN

Including React and React-DOM into a project through a CDN (Content Delivery Network) involves adding the necessary script tags to your HTML file.

1. Create an HTML file for your project or open an existing one.
2. Find out the URLs for the React and React-DOM CDN resources. You can use popular CDN providers like unpkg, cdnjs, or jsDelivr. For this example, we’ll use the URLs from the unpkg CDN.

<script crossorigin src=”https://unpkg.com/react@18/umd/react.development.js“></script>

<script crossorigin src=”https://unpkg.com/react-dom@18/umd/react-dom.development.js“></script>

Note: You need to change the React version from time to time.

1. Open your HTML file and add the script tags for React and React-DOM within the <head> or <body> section. It’s generally recommended to include these scripts before your own JavaScript code.
2. That’s it! You have included React and React-DOM in your project using CDN. Now you can proceed to write your React code and use React and ReactDOM as global objects in your JavaScript files.

But Including React directly through a CDN can have some drawbacks and is generally considered a less preferred approach for larger projects.

Few reasons why it may not be ideal:

• Lack of control over versions
• Limited functionality
• Performance impact
• Security concerns
• Lack of build optimizations

That’s why we need a form of local storage to fetch the functionalities of React and React DOM. This is where NPM packages come into play.

Include React and React-DOM into the project through NPM

Including React and React-DOM in a project through NPM (Node Package Manager) involves the following steps:

1. Create a new project directory or navigate to your existing project directory using a terminal or command prompt.
2. Initialize a new NPM project by running the following command: npm init, This command will create a package.json file that will track your project’s dependencies and configuration.
3. Install React and React-DOM as dependencies by running the following command: npm install react react-dom, This command installs the latest stable versions of React and React-DOM and adds them as dependencies in your package.json file.
4. Now Create your React application code in a JavaScript file as well as an HTML file that will load your JavaScript code and provide a root element where the React element will be rendered.

In order to minify our React code, we require a tool that can handle the web assets and minify our code. Therefore, I will be using the parcel build tool.

Building React app using parcel

Let’s suppose we have built a React app. Here is the code:

HTML: 

<!DOCTYPE html>

<html lang=“en“>

  <head>

    <meta charset=“UTF-8“ />

    <meta name=“viewport“ content=“width=device-width, initial-scale=1.0“ />

    <link rel=“stylesheet“ href=“index.css“ />

    <title>React App</title>

  </head>

  <body>

    <div class=“root“></div>

    <script type=“module“ src=“App.js“></script>

  </body>

</html>

JavaScript:

import React from “react“;

import ReactDOM from “react-dom/client“;

// Step 1: Create a react element

const reactElement = React.createElement(

  “h1“,

  { id: “title“ },

  “Hello World, from React…“

);

// Step 2: Create a root element

const rootElement = ReactDOM.createRoot(document.querySelector(“.root“));

// Step 3: Render element on the web page.

rootElement.render(reactElement);

We need to execute this code in a browser, but we cannot run it directly in the browser. Therefore, I am utilizing Parcel to handle all the necessary tasks before displaying the webpage in the browser.

Parcel is a modern and zero-configuration build tool that simplifies the build process by handling tasks like bundling, minification, and asset management out of the box.

Its easy-to-use allows developers to focus on writing code rather than spending time configuring complex build systems. With its great support for various web technologies, Parcel becomes an excellent choice.

Set-Up Parcel

Setting up Parcel for a React app is a simple process. Once React and React DOM are installed via NPM, follow these steps:

1. Install Parcel as a development dependency in your project:

npm install –D parcel

1. Create your React components and the entry point for your application inside the package.json file. Usually, the entry point is named index.js or App.js.
2. Create an HTML file as well as a root for our project. This file will serve as the entry point for Parcel to bundle our React application.
3. Now, write a React component in a JavaScript file. Import React and React DOM at the top of the JS file, and render them into the DOM using the render() method.
4. We are ready to render our React app in the browser using the command npx parcel [entry file name]. However, we can also customize this command by using scripts inside the package.json file.

{

  “scripts“: {

    “start“: “parcel index.html“

  }

}

1. To render our application in the browser, we need to execute the “npm start” command in the terminal. The Parcel will automatically bundle your React app, and you should be able to access it at http://localhost:1234 or another available port, which will be displayed in your terminal as well.

Conclusion

In conclusion, CRA and Vite are excellent development tools that have simplified the process of creating modern web applications. By abstracting away much of the underlying complexity, they allow developers to get started quickly and focus on building the actual application rather than configuring the build process or dealing with tooling intricacies.

While Parcel is an alternative that allows developers to gain a more comprehensive understanding of the engineering principles driving their applications. Embracing this journey can lead to improved skills, a deeper appreciation for the development process, and ultimately, more powerful and efficient web applications. So, whether you choose the simplicity of CRA and Vite or Parcel, the most important thing is to keep learning, experimenting, and evolving as a developer.

Undoubtedly, React is the most popular front-end library and one of the trendiest technologies to learn. According to the 2022 State of JS survey, React holds the top position in terms of usage.

In this detailed blog, we will explore some of the best practices that you should follow as a React developer. So Let’s get started.

File and folder organization 

One of the biggest challenges faced by React developers is maintaining project organization. When files and folders are mixed up, it becomes difficult for maintainers to navigate and manage the codebase effectively.

One good approach is to divide the folder structures into a more self-explanatory structure. For example:

• Root Structure
• src (Source Directory)
  • components
  • containers/pages
  • services/APIs
  • styles
  • assets
  • utils (utilities)
• Configuration Files (e.g., Webpack, environment variables)
• Tests

The above structure is a very basic one; for complicated projects, you can choose a much more maintainable folder structure. If you are using frameworks like Next.js, you will already have a default structure that you need to follow.

Keep your code DRY

React came into existence for one main reason: to make web development easier. Keeping your React code “DRY” (Don’t Repeat Yourself) is a best practice that can improve code maintainability, reduce duplication, and enhance overall development efficiency. Here are some tips for keeping your React codebase DRY:

• Make components independent: When you are creating a component, make it as minimal as possible. It will make your development as well as the post-development process much easier. 
• Make it reusable: As the component becomes independent, you can reuse the component in other sections of the websites and you can pass data as props and make it dynamic.

• Extracting Logic: If you are using the same logic in multiple places, instead of repeating yourself, you can make a separate module/file which you can reuse by importing the function.

• Use Libraries and Utilities: Leverage existing libraries and utility functions to handle common tasks instead of reinventing the wheel. For example, libraries like lodash can help with data manipulation, validation, and other common operations.

Use Hooks

React Hooks became very popular and it is now the standard way of doing things in React. Most developers don’t know most of the hooks. Two popular hooks are useState() and useEffect(). But there may be situations where you can more appropriate hooks.

When a parent component renders, all child components typically re-render, even if their props haven’t changed. However, by using use callback, you can memoize the callback function and prevent unnecessary re-renders of child components that depend on that callback.

Avoid Using Indexes as a Key Prop

When rendering lists in React, it’s essential to assign unique keys to each item. Keys allow React to identify items within an array accurately, making it easier to determine which items have been inserted, modified, or removed. While it may be tempting to use the index of the array as the key, it can lead to problems when the list of items changes.

const Items = () => {

  const arr = [“apple”, “banana”, “cat”, “dog”, “egg”];

return (

    <>

      {arr.map((elem, index) => (

        <li key={elem}>{elem}</li>

      ))}

    </>

  );

};

While using the index as the key occasionally works, it can cause issues when the list undergoes expected changes. One way to solve this is using the item value itself as the key, we ensure that each item is uniquely identified within the array. This approach allows React to accurately track changes in the list, even if the order or position of items changes dynamically.

You can also use UUID, which gives you a unique value. But if you are just rendering less than 50 (not a specific number) list, you are totally fine using the key as the actual value in the array.

Component Naming

Properly naming your components is a crucial aspect of writing clean and maintainable React code. Better component names enhance code readability and understanding, making it easier for you and other developers to navigate and work with your codebase.

When naming your components, consider the following best practices:

• Use Descriptive and Clear Names: Choose component names that accurately describe their purpose and functionality.
• Capitalize Component Names: This convention helps differentiate components from regular HTML elements and allows React to distinguish between them during the compilation process.
• Avoid Generic Names and Ambiguity: Avoid generic or ambiguous names that do not provide enough context about the component’s purpose or usage. Generic names like Wrapper, Container, or Item can quickly become confusing when working with multiple components or a large codebase.
• Use CamelCase for Multi-Word Names: When a component name consists of multiple words, use CamelCase (also known as PascalCase) to distinguish between the words. For example, LoginForm, UserProfile, or SearchResults. 

Opt for React Fragments Over divs

When returning code from a React component, it’s common to wrap it in a single tag. The traditional approach has been to use <div> as the wrapping element. However, it’s considered a best practice to utilize React fragments instead.

Every HTML tag or <div> you use in your code comes with an associated memory cost. As the number of <div> tags increases, so does the memory required by your website. This additional memory usage leads to higher power consumption and increased loading times, ultimately resulting in a slower website speed and a subpar user experience.

React fragments provide a solution to this problem. Fragments allow you to group elements without introducing any extra nodes in the DOM. Unlike <div>, fragments don’t create additional elements, reducing the memory footprint and improving overall performance.

const MyComponent = () => {

  return (

    <>

      <h1>Heading</h1>

      <p>Paragraph 1</p>

      <p>Paragraph 2</p>

    </>

  );

};

export default MyComponent;

Prefer Passing Objects

When passing data to components in React, it’s common to pass sets of primitive values as separate props. However, to streamline and organize the data being passed, it is recommended to prefer passing an object instead. By encapsulating related properties within an object, you can reduce the number of props being passed and improve code maintainability.

For example, this is an anti-pattern

const EmployeeAccount = ({ name, age, department,position}) => {

  return (

    <div>

      <h2>{name}</h2>

      <p> {age}</p>

      <p>Dept: {department}</p>

      {/* Additional employee details can be accessed from the ‘user’ object */}

    </div>

  );

};

const MyComponent = () => {

return(

      <EmployeeAccount name={“your name”} age={7} position={“engineer”} department=”testing” />

)

}

You can do this in a much simpler and better way, like this:

const EmployeeAccount = ({ user }) => {

  return (

    <div>

      <h2>{user.name}</h2>

      <p>Email: {user.email}</p>

      <p>ID: {user.id}</p>

      {/* Additional employee details can be accessed from the ‘user’ object */}

    </div>

  );

};

const MyComponent = () => {

  const user = {

    name: ‘John Doe’,

    email: ‘johndoe@example.com’,

    id: 12345,

    // Additional employee details

    position: ‘Software Engineer’,

    Department: ‘Engineering’,

  };

  return (

    <div>

      <EmployeeAccount user={user} />

    </div>

  );

};

Avoid Mixing Data and Logic in Components

In React, it is considered a good practice to separate the presentation and business logic within your components. However, there might be instances where the temptation arises to mix data and logic within a component. This often stems from the desire to ensure data availability for other parts of the application.

To address this, creating a new component specifically responsible for managing the data and displaying it on the page is recommended. This approach is commonly referred to as a smart component. By separating the business logic and data presentation into distinct components, you can encapsulate the logic and data to display it on the page.

Embrace the Power of TypeScript in React Development

Although React offers flexibility and efficiency, the use of plain JavaScript leaves room for potential errors and difficulties in maintaining larger codebases. This is where TypeScript comes into play.

TypeScript is a statically-typed superset of JavaScript that brings additional benefits to React development. By adding static typing and other language features, TypeScript provides several advantages for building robust and scalable React applications.

Some of the benefits of using TypeScript are:

• Type Safety and Error Detection: TypeScript helps identify common mistakes and potential bugs before runtime. It provides a safety net, allowing you to detect and fix issues early in the development process.
• Improved Code Maintainability:  By specifying types for variables, function parameters, and return values, you make the code self-documenting.
• Enhanced Tooling and IDE Support: TypeScript comes with a rich set of tools and IDE support. Popular editors like Visual Studio Code provide intelligent autocompletion, code navigation, and refactoring capabilities specific to TypeScript.
• Scalability and Refactoring: TypeScript helps in refactoring efforts by providing a safety net during code modifications. Static typing allows you to make changes confidently, knowing that the compiler will highlight any breaking changes and guide you in updating the affected areas.

Start using Next.js

React has made it easy for front-end developers to create applications using component-based architecture and a declarative approach. However, when it comes to building complex applications with server-side rendering (SSR), routing, and optimized performance, Next.js emerges as a valuable tool in the React ecosystem.

Some of the advantages of using Next.js are:

• In-built Routing: Next.js provides a similar routing which is like folder and file-based routing. You can create a folder, which will be the URL of the page and inside the page.jsx file, you can write the logic for that part.
• Full-stack capabilities: Next.js provides full-stack capabilities, allowing you to build both the front-end and back-end of your application using a single framework. This eliminates the need for separate server-side frameworks and simplifies the development process.
• Better SEO: Next.js enables search engines to crawl and index your website effectively, resulting in improved search engine rankings and better discoverability.
• Inbuilt Image Optimization: Next.js provides built-in image components that automatically optimize images with a powerful native API. This feature is game-changing, improving the experience for both developers and users alike.

There are many such industry practices that you can follow so that your code can be much more readable and maintainable. 

Wrapping it Up!

Congratulations on making it to the end of this blog!

In this detailed blog, we have looked at various best practices to follow. We have also looked into the advantages of using TypeScript and Next js. Following these industry practices, developers can benefit from enhanced efficiency, improved code quality, etc.

The post React JS Best Practices to follow in 2023 appeared first on Talent500 blog.

It makes it easier for developers to create beautiful and responsive user interfaces with ease. In this blog, we will look at how to build simple and efficient components with React-Bootstrap.

Installation

To get started with React-Bootstrap, you will need to install it in your project. You can do this by running the following command in your terminal:

npm install react-bootstrap bootstrap

This will install both React-Bootstrap and Bootstrap in your project.

Creating a Button Component

Let’s start by creating a simple button component using React-Bootstrap. Open your text editor and create a new file called Button.js. Then, add the following code:

import React from ‘react’;

import { Button } from ‘react-bootstrap’;

const MyButton = () => {

  return (

    <Button variant=”primary”>Click Me</Button>

  );

}

export default MyButton;

In the code above, we import the Button component from React-Bootstrap and use it to create our own MyButton component. We set the variant prop to “primary” to give the button a blue colour. You can also use other variants such as “secondary”, “success”, “danger”, “warning”, “info”, “light”, and “dark”.

To use this component in your application, you can import it and add it to your JSX code as follows:

import React from ‘react’;

import MyButton from ‘./Button’;

const App = () => {

  return (

    <div>

      <MyButton />

    </div>

  );

}

export default App;

Creating a Form Component

Let’s now create a form component using React-Bootstrap. Open your text editor and create a new file called Form.js. Then, add the following code:

import React from ‘react’;

import { Form, Button } from ‘react-bootstrap’;

const MyForm = () => {

  return (

    <Form>

      <Form.Group controlId=”formBasicEmail”>

        <Form.Label>Email address</Form.Label>

        <Form.Control type=”email” placeholder=”Enter email” />

        <Form.Text className=”text-muted”>

          We’ll never share your email with anyone else.

        </Form.Text>

      </Form.Group>

      <Form.Group controlId=”formBasicPassword”>

        <Form.Label>Password</Form.Label>

        <Form.Control type=”password” placeholder=”Password” />

      </Form.Group>

      <Button variant=”primary” type=”submit”>

        Submit

      </Button>

    </Form>

  );

}

export default MyForm;

In the code above, we import the Form and Button components from React-Bootstrap and use them to create our own MyForm component. We use the Form.Group component to group form controls together, and set the controlId prop to provide a unique identifier for each group. We use the Form.Label component to add labels to form controls and the Form.Control component to create form inputs.

To use this component in your application, you can import it and add it to your JSX code as follows:

import React from ‘react’;

import MyForm from ‘./Form’;

const App = () => {

  return (

    <div>

      <MyForm />

    </div>

  );

}

export default App;

Creating a Navbar Component

Let’s now create a navbar component using React-Bootstrap. Open your text editor and create a new file called Navbar.js. Then, add the following code

import React from ‘react’;

import { Navbar, Nav, Form, FormControl, Button } from ‘react-bootstrap’;

const MyNavbar = () => {

  return (

    <Navbar bg=”light” expand=”lg”>

      <Navbar.Brand href=”#home”>My Website</Navbar.Brand>

      <Navbar.Toggle aria-controls=”basic-navbar-nav” />

      <Navbar.Collapse id=”basic-navbar-nav”>

        <Nav className=”mr-auto”>

          <Nav.Link href=”#home”>Home</Nav.Link>

          <Nav.Link href=”#link”>Link</Nav.Link>

        </Nav>

        <Form inline>

          <FormControl type=”text” placeholder=”Search” className=”mr-sm-2″ />

          <Button variant=”outline-success”>Search</Button>

        </Form>

      </Navbar.Collapse>

    </Navbar>

  );

}

export default MyNavbar;

In the code above, we import the Navbar, Nav, Form, FormControl, and Button components from React-Bootstrap and use them to create our own MyNavbar component. We use the Navbar.Brand component to add a brand to the navbar and the Navbar.Toggle and Navbar.Collapse components to create a responsive navbar. We use the Nav component to create links in the navbar, and the Form and FormControl components to create a search bar.

To use this component in your application, you can import it and add it to your JSX code as follows:

import React from ‘react’;

import MyNavbar from ‘./Navbar’;

const App = () => {

  return (

    <div>

      <MyNavbar />

    </div>

  );

}

export default App;.

More Features and Components in React-Bootstrap

There are many more components and features that you can explore to create even more complex and powerful UIs. In this section, we will take a closer look at some of these features and provide examples of how to use them.

Modals

Modals are a great way to display content and gather user input in a non-intrusive way. With React-Bootstrap, creating a modal is as simple as importing the Modal component and using it in your code.

javascript

Copy code

import React, { useState } from ‘react’;

import { Modal, Button } from ‘react-bootstrap’;

const MyModal = () => {

  const [show, setShow] = useState(false);

  const handleClose = () => setShow(false);

  const handleShow = () => setShow(true);

  return (

    <>

      <Button variant=”primary” onClick={handleShow}>

        Launch demo modal

      </Button>

      <Modal show={show} onHide={handleClose}>

        <Modal.Header closeButton>

          <Modal.Title>Modal heading</Modal.Title>

        </Modal.Header>

        <Modal.Body>Modal content goes here</Modal.Body>

        <Modal.Footer>

          <Button variant=”secondary” onClick={handleClose}>

            Close

          </Button>

          <Button variant=”primary” onClick={handleClose}>

            Save Changes

          </Button>

        </Modal.Footer>

      </Modal>

    </>

  );

}

export default MyModal;

In the code above, we create a MyModal component that contains a button that launches a modal when clicked. We use the useState hook to manage the state of the modal (whether it is visible or not), and the handleClose and handleShow functions to show and hide the modal. Inside the Modal component, we can add any content we want, including headers, bodies, and footers, as well as buttons to close or save changes.

Pagination

Pagination is a useful feature for displaying large sets of data in a more manageable way. With React-Bootstrap, creating a pagination component is easy.

import React from ‘react’;

import { Pagination } from ‘react-bootstrap’;

const MyPagination = () => {

  return (

    <Pagination>

      <Pagination.First />

      <Pagination.Prev />

      <Pagination.Item active>{1}</Pagination.Item>

      <Pagination.Item>{2}</Pagination.Item>

      <Pagination.Item>{3}</Pagination.Item>

      <Pagination.Ellipsis />

      <Pagination.Item>{10}</Pagination.Item>

      <Pagination.Next />

      <Pagination.Last />

    </Pagination>

  );

}

export default MyPagination;

In the code above, we create a MyPagination component that contains a pagination component. We use the Pagination.First, Pagination.Prev, Pagination.Item, Pagination.Ellipsis, Pagination.Next, and Pagination.Last components to create a complete pagination UI. We can use the active prop to indicate the current page, and the disabled prop to disable certain pages or buttons.

Tooltips

Tooltips are a great way to provide additional information or context to your UI elements. With React-Bootstrap, creating a tooltip is as simple as adding the title prop to any element.

import React from ‘react’;

import { OverlayTrigger, Tooltip, Button } from ‘react-bootstrap’;

const MyTooltip = () => {

  const renderTooltip = (props) => (

    <Tooltip id=”button-tooltip” {…props}>

      Simple tooltip

    </Tooltip>

  );

  return (

    <OverlayTrigger

      placement=”right”

      delay={{ show: 250

}}

  overlay={renderTooltip}

>

  <Button variant=”secondary”>Hover me</Button>

</OverlayTrigger>

);

}

export default MyTooltip;

In the code above, we create a `MyTooltip` component that contains a button with a tooltip. We use the `OverlayTrigger` component to define the placement and delay of the tooltip, as well as the content of the tooltip itself. The `renderTooltip` function returns a `Tooltip` component with the text “Simple tooltip”. We then wrap the `Button` component in the `OverlayTrigger` component and pass in the `renderTooltip` function as the `overlay` prop.

Forms

Forms are a critical component of any UI, and React-Bootstrap provides many useful components for creating forms, including form groups, form controls, and form labels.

import React from ‘react’;

import { Form, Button } from ‘react-bootstrap’;

const MyForm = () => {

  return (

    <Form>

      <Form.Group controlId=”formBasicEmail”>

        <Form.Label>Email address</Form.Label>

        <Form.Control type=”email” placeholder=”Enter email” />

<Form.Text className=”text-muted”>

          We’ll never share your email with anyone else.

        </Form.Text>

      </Form.Group>

      <Form.Group controlId=”formBasicPassword”>

        <Form.Label>Password</Form.Label>

        <Form.Control type=”password” placeholder=”Password” />

      </Form.Group>

      <Form.Group controlId=”formBasicCheckbox”>

        <Form.Check type=”checkbox” label=”Check me out” />

      </Form.Group>

      <Button variant=”primary” type=”submit”>

        Submit

      </Button>

    </Form>

  );

}

export default MyForm;

In the code above, we create a MyForm component that contains a basic form. We use the Form.Group component to group related form controls together, and the Form.Label, Form.Control, and Form.Text components to create labels, input fields, and additional text. We also use the Form. Check the component to create a checkbox, and the Button component to create a submit button.

Conclusion

React-Bootstrap provides a wealth of components and features for building simple and efficient UIs. In this blog post, we covered some of the basic components, including alerts, buttons, cards, and navbars, as well as some more advanced components, including modals, pagination, tooltips, and forms. By using these components, you can create powerful and dynamic UIs that are both easy to use and visually appealing.

We hope this blog post has helped get you started with React-Bootstrap.

The post Building Simple and Efficient Components With React-Bootstrap appeared first on Talent500 blog.

In this blog post, we will explore how to build a React Native app using React Native Hooks. React Native Hooks are a set of built-in functions that allow developers to add state and lifecycle features to functional components, making them more powerful and efficient.

Why Use React Native Hooks?

React Native Hooks provide several benefits for developers when building mobile apps. They offer a concise and intuitive way to manage state and side effects in functional components, without the need for class components and lifecycle methods. Some of the key advantages of using React Native Hooks include:

Simpler Syntax: React Native Hooks allow developers to manage state and side effects using simple and concise functions, such as useState, useEffect, and useReducer, which can be used directly in functional components.

Improved Performance: Functional components with React Native Hooks are optimized for performance, as they do not carry the overhead of class components and lifecycle methods. This can result in faster and more efficient apps.

Code Reusability: React Native Hooks promote code reusability, as they allow developers to encapsulate logic into custom hooks, which can be easily reused across different components and projects.

Better Debugging: React Native Hooks provide improved debugging capabilities, as they offer better error messages and debugging tools compared to class components and lifecycle methods.

Getting Started with React Native Hooks

Now that we understand the benefits of using React Native Hooks, let’s dive into how to get started with building a React Native app using Hooks.

Prerequisites:

Before we begin, make sure you have the following prerequisites in place:

• Node.js and npm installed on your machine
• React Native CLI installed globally
• Basic understanding of React Native and JavaScript concepts

Step 1: Create a New React Native Project

To create a new React Native project, open your terminal and run the following command:

npx react-native init MyReactNativeApp

This will create a new React Native project named “MyReactNativeApp” with the default project structure.

Step 2: Create a Functional Component

Next, let’s create a functional component for our app. Open the “App.js” file in the root of your project and replace the default code with the following:

import React, { useState, useEffect } from ‘react’;

import { View, Text, StyleSheet } from ‘react-native’;

const App = () => {

  const [count, setCount] = useState(0);

  useEffect(() => {

    // Code to be executed on component mount

    // Clean up code

    return () => {

      // Code to be executed on component unmount

    }

  }, []);

  return (

    <View style={styles.container}>

      <Text style={styles.text}>Hello React Native Hooks!</Text>

      <Text style={styles.text}>Count: {count}</Text>

      <Text style={styles.text} onPress={() => setCount(count + 1)}>Increment</Text>

    </View>

  );

};

const styles = StyleSheet.create({

  container: {

    flex: 1,

    justifyContent: ‘center’,

    alignItems: ‘center’,

  },

  text: {

    fontSize: 20,

    marginVertical: 10,

  },

});

export default App;

In the above code, we have used the useState and useEffect hooks from React to manage state and side effects in our functional component. The useState hook is used to manage the count state, which is initially set to 0. 

In the above code, we have used the useState and useEffect hooks from React to manage state and side effects in our functional component. The useState hook is used to manage the count state, which is initially set to 0. 

The useEffect hook is used to execute code on component mount and unmount. In this case, we have an empty dependency array ([]), which means the useEffect code will only run on the component mount and not re-run on subsequent renders.

Step 3: Update the UI with State Changes

Now that we have set up our functional component with state using React Native Hooks, let’s update the UI to reflect the changes in the count state. Update the return statement in the App component as follows:

return (

  <View style={styles.container}>

    <Text style={styles.text}>Hello React Native Hooks!</Text>

    <Text style={styles.text}>Count: {count}</Text>

    <TouchableOpacity

      style={styles.button}

      onPress={() => setCount(count + 1)}

    >

      <Text style={styles.buttonText}>Increment</Text>

    </TouchableOpacity>

  </View>

);

In the above code, we are using the count state in the Text component to display the current count value. 

We are also using the TouchableOpacity component, which is a built-in component in React Native, to create a button that calls the setCount function when pressed, incrementing the count value by 1.

Step 4: Add Side Effects with useEffect

In our previous code, we added an empty useEffect hook that runs on component mount and unmount. Let’s now update our useEffect hook to add a side effect that runs whenever the count state changes. Update the useEffect hook as follows:

useEffect(() => {

  // Code to be executed on component mount

  // Clean up code

  return () => {

    // Code to be executed on component unmount

  }

}, [count]);

In the above code, we have added the count state as a dependency in the useEffect hook by passing it as an array [count]. This means that the useEffect code will now run whenever the count state changes. 

This option can be used to perform side effects, such as making API calls, updating the UI, or any other logic that needs to happen when the count value changes.

Step 5: Custom Hooks for Reusability

One of the powerful features of React Native Hooks is the ability to encapsulate logic into custom hooks, which can be easily reused across different components and projects. 

Let’s create a custom hook that manages the count state and side effect logic. Create a new file named “useCounter.js” in the root of your project and add the following code:

import { useState, useEffect } from ‘react’;

const useCounter = () => {

  const [count, setCount] = useState(0);

  useEffect(() => {

    // Code to be executed on component mount

    // Clean up code

    return () => {

      // Code to be executed on component unmount

    }

  }, [count]);

  const increment = () => {

    setCount(count + 1);

  };

  return {

    count,

    increment,

  };

};

export default useCounter;

In the above code, we have defined a custom hook called useCounter that uses the useState and useEffect hooks from React to manage the count state and side effect logic. 

The hook returns an object with the count value and an increment function, which can be used to update the count value.

Now, we can update our App component to use the useCounter custom hook as follows:

import React from ‘react’;

import { View, Text, StyleSheet } from ‘react-native’;

import useCounter from ‘./useCounter’;

const App = () => {

  const { count, increment } = useCounter();

  return (

    <View style={styles.container}>

<Text style={styles.text}>Hello React Native Hooks!</Text>

<Text style={styles.text}>Count: {count}</Text>

<TouchableOpacity

     style={styles.button}

     onPress={increment}

   >

<Text style={styles.buttonText}>Increment</Text>

</TouchableOpacity>

</View>

);

};

const styles = StyleSheet.create({

container: {

flex: 1,

justifyContent: ‘center’,

alignItems: ‘center’,

},

text: {

fontSize: 24,

marginBottom: 16,

},

button: {

backgroundColor: ‘#007bff’,

padding: 16,

borderRadius: 4,

},

buttonText: {

color: ‘#fff’,

fontSize: 18,

},

});

export default App;

In the above code, we are now using the increment function from the useCounter hook to update the count value when the button is pressed. 

This allows us to encapsulate the state management and side effect logic into a custom hook, making our code more modular and reusable.

Conclusion

In this tutorial, we have learned how to build a React Native app using React Native Hooks. We started by setting up a functional component with state using the useState hook, updating the UI with state changes, adding side effects with the useEffect hook, and finally encapsulating the logic into a custom hook for reusability. React Native Hooks provide a modern and concise way to manage state and side effects in React Native apps, allowing developers to write more efficient and maintainable code.

By leveraging the power of React Native Hooks, you can create complex and interactive mobile apps with ease. Remember to always follow best practices when using hooks, such as providing a dependency array to useEffect, and making sure to clean up any side effects in the return function of useEffect. 

With React Native Hooks, you can build powerful and performant apps that provide a seamless user experience on both iOS and Android platforms. Happy coding!

However, this is one of the most important topics in JavaScript, known as a module. But the main purpose of this article is to understand exporting and importing components in React JS. In addition, near the end of the article, you will find a table detailing the various methods for importing and exporting components in React JS.

After completing this article you will learn:

• Named export
• Named import
• Default export
• Default import
• Combine more than one import statement
• Aliasing the binding

So, without further ado, let’s get into the article!

First and foremost, what is the actual meaning of import and export in general?

• Import: Imports are goods or services that are brought into one country from another country. Let’s say an Indian wants to buy a Tesla car. Since Tesla doesn’t manufacture its cars in India at present, the person will have to import the car from another country (let’s say, USA).
• Export: Export means sending goods and services to another country. In the above example, America is sending Tesla cars to India. That means America is exporting its Tesla cars to India.

Therefore, America is exporting Tesla cars, and India is importing them.

Similarly, in React JS, we need to export components, functions, or values in order to use those components in another file (module). To use those exported components in another file, we have to import them first.

So, there are two primary ways to export and import components( or values) in React JS.

1. Named export and import
2. Default export and import

We can use one or both of them in order to export and import components.

Named export

Suppose we want to export these two functions in another React component (file or module). To export these functions into another component as a named export, we just need to use the export keywords in front of the functions.

The export keyword has made these functions available to other components, allowing them to be used by other React components in the future.

//America.js

// Named import

export function Apple() { 

  return <h1>I'm sending MacBook.</h1>;

}

// Named import

export function Windows() {

  return <h1>I'm sending Windows.</h1>;

}

In the above code, the ‘America.js’ component has two functions that are Apple() and Windows() and in front of these functions, the export keywords are mentioned. That means they will be used later in other React components.

We can have multiple Named exports in a React component, so we can use the curly braces { } to export more than one Named export instead of exporting individually.

See in the below code, I have grouped together all functions and variables inside the curly braces that can be easily accessible in other React components.

//America.js

function Apple() {

  return <h1>I'm sending MacBook.</h1>;

}

function Windows() {

  return <h1>I'm sending Windows.</h1>;

}

// Exporting all items at one go using curly braces.

// Named import

export { Apple, Windows };

Named import

Once we define a component with the export keyword, we can now access and import those exported functions using the import keyword.

Now we are going to import those functions and variables, which are being exported by the “America.js” component, into a component called “India.js.”

//India.js

// Named import

import { Apple } from "./America.js"; 

// Named import

import { Windows } from "./America.js";

In the above code, the import keywords are used to import the Apple() and Windows() functions, which are exported by the “America.js” file.

Also, we must enclose the functions or values in curly braces {…} and give them the same name as defined from where they are exported. That’s why these imports are called exports. We cannot change the name of the imported bindings (bindings are nothing but functions, values, or classes).

But also we can import multiple bindings into a single line of code, separated by commas ( , ).

//India.js

// Named import

import { Apple, Windows} from "./America.js";

Now we can use these bindings inside the ‘India.js’ component.

//India.js

 

// Named import

import { Apple, Windows } from "./America"; 

function India() {

  return (

    <>

      <Apple />

      <Windows />

    </>

  );

}

Have a look at the illustration about Named export and import.

Default Export

The default export is also used for exporting components, values, classes, etc. in React JS, but only one element can be exported to another component at a time as a default export. In other words, a file can have only one default export.

Suppose we want to export the “Tesla” component to other components from the “America.js” file as a default export, so the syntax will be like this:

//America.js

function Tesla() {

  return <h1>I'm sending the Tesla car.</h1>;

}

// Default export

export default Tesla;

In the above code, there is a function called “Tesla”, and this function is exported as a default export. We just need to put export and default keywords in front of the function.

But we can also omit the name of the function in the above code snippet because the “America.js” file represents the name of the function. Have a look at the syntax below.

//America.js

// Default export

export default function () {  

  return <h1>I'm sending the Tesla car.</h1>;

}

Default Import

Now we can easily import the above component into other components by following the same technique as the Named import, but there are two main differences.

• We do not need to wrap the binding inside the curly braces.
• Can be given any name as the name of that exported binding.

//India.js

// Default import

import Car from "./America.js"; 

// Named imports

import { Apple, Windows} from "./America.js"; 

function India() {

  return (

    <>

      <Car />

      <Apple />

      <Windows />

    </>

  );

}

In the above code, we can put any name in the place of “Car” as the default import. Have a look at the illustration below.

Combine more than one import statement

As you can see in the above code snippets, I’m importing named and default exported bindings in the two lines of code. But we can also import both ways on the same line of code in a component.

In order to import default and named bindings, we must keep these two main points in mind.

• The default bindings must come first during importing.
• The non-default (named) binding must be surrounded by curly braces {…}.

// India.js

// Combined named and default imports

import Car, { Apple, Windows } from "./America";

function India() {

  return (

    <>

      <Car />

      <Apple />

      <Windows />

    </>

  );

}

In the above code, the ‘Car’ is a default import but ‘Apple’ and ‘Windows’ are the Named imports.

Aliasing the binding

We can also change the name of the bindings before exporting them to other components using the “as” keyword.

//America.js

function Windows() {

  return <h1>I'm sending Windows.</h1>;

}
 
// Named export

export { Windows as Microsoft };

In the above code snippet, I have changed the name of the Windows() function to the Microsoft() function using the “as” keyword. And this new alias name will be used when importing it into other components.

Have a look at the code below.

//India.js

// Named import

import { Microsoft } from "./America";

function India() {

  return (

    <>

      <Microsoft />

    </>

  );

}

A concise table

Summary

• We have seen two ways of exporting data that can be used in other components. To use those data we must first import the bindings according to the type of exports.
• A default export can be only one in a file or module.
• But a module can have more than one Named export.

Conclusion

In conclusion, there are two ways to import and export components in React JS, each with its own advantages and use cases. The most common method is the default export, which is simple and efficient for exporting a single component.

While named exports are useful when exporting multiple components or constants from a single module. It is also possible to export components and constants together with the object shorthand syntax.

Install redux

If you cloned the repo from the previous example, check that the package’s dependencies are correct. The json file looks like this:

“dependencies”: {
“@react-native-community/masked-view”: “0.1.5”,
“expo”: “~36.0.0”,
“react”: “~16.9.0”,
“react-dom”: “~16.9.0”,
“react-native”: “https://github.com/expo/react-native/archive/sdk-36.0.0.tar.gz”,
“react-native-gesture-handler”: “~1.5.0”,
“react-native-paper”: “3.4.0”,
“react-native-reanimated”: “~1.4.0”,
“react-native-safe-area-context”: “0.6.0”,
“react-native-screens”: “2.0.0-alpha.12”,
“react-navigation”: “4.0.10”,
“react-navigation-stack”: “2.0.10”,
“react-redux”: “7.1.3”,
“redux”: “4.0.5”
},

To integrate and manage the state with Redux, now install the following dependencies from a terminal window.
yarn add redux react-redux lodash.remove

The directory structure used to organise Redux-related files will be based on the pragmatic method known as ducks. The duck’s design enables the use of modular reducers within the app itself. There is no need to create separate files for actions, types, and action creators. Instead, declare them all in a single modular file; however, if more than one reducer is required, specify several reducer files.

Adding creators and action types

When utilising Redux to manage the overall state of the application, the state is represented by a single JavaScript object. Think of this object as read-only, since you cannot make changes to this state directly. It requires actions to do so.

In Redux, actions are analogous to events. They can be activated by button presses, timers, or network requests.

To begin, establish a subfolder named redux under the src/ directory. Create a new file named notesApp.js within it.

Thus far, the programme allows the user to add notes. Let’s start by creating two action kinds and their creators in the newly generated files. The user will be able to remove an item from the ViewNotes screen using the second action type.

// Action Types
export const ADD_NOTE = ‘ADD_NOTE’
export const DELETE_NOTE = ‘DELETE_NOTE’

Next, for each action type, define action creators. The first will be triggered when the note is saved, and the second will be triggered when the note is deleted.

// Action Creators
let noteID = 0
export function addnote(note) {
  return {
    type: ADD_NOTE,
    id: noteID++,
    Note
  }
}
export function deletenote(id) {
  return {
    type: DELETE_NOTE,
    payload: id
  }
}

Adding a reducer

A reducer is who receives the action. The application’s state changes whenever an action is performed. The reducers are in charge of managing the application’s state.

A reducer is a pure function that determines the future state depending on the previous or starting state. If the state remains unaltered, it always returns the same result. It accepts two inputs (state and action) and must return the default state.

The initial state will be an empty array. When you’ve specified action creators, add the following. Likewise, at the top of the notesApp.js file that was installed at the start of this post, import the remove tool from the lodash.remove npm package:

// import the dependency
import remove from ‘lodash.remove’
// reducer
const initialState = []
function notesReducer(state = initialState, action) {
  switch (action.type) {
    case ADD_NOTE:
      return [
        …state,
        {
          id: action.id,
          note: action.note
        }
      ]
  case DELETE_NOTE:
      const deletedNewArray = remove(state, obj => {
        return obj.id != action.payload
      })
      return deletedNewArray
    Default:
      return state
  }
}
export default notesReducer

Configure a Redux store

A store is an object that connects actions and reducers. It delivers and maintains state at the application level rather than at the level of individual components. Redux does not have an opinion about which framework or library should utilise it.

When you’ve finished creating the reducer, add a new file named store.js to the src/redux/ directory. Import the function createStore from redux, as well as the app’s only reducer for the time being.

import { createStore } from ‘redux’
import notesReducer from ‘./notesApp’
const store = createStore(notesReducer)
export default store

Open the entry point file App.js and import the store as well as the react-redux npm package’s high order component (HOC) Provider to link this Redux store to the React Native app. This HOC assists you in passing the store down to the other components of the current app.

import React from ‘react’
import { Provider as PaperProvider } from ‘react-native-paper’
import AppNavigator from ‘./src/navigation’
import { Provider as StoreProvider } from ‘react-redux’
import store from ‘./src/redux/store’
// modify the App component
export default function App() {
  return (
    <StoreProvider store={store}>
      <PaperProvider>
        <AppNavigator />
      </PaperProvider>
    </StoreProvider>
  )
}

That’s all! The Redux store is fully set up and ready to go!

Accessing global state

The useSelector Hook is given to access state while managing it using Redux. It’s analogous to the mapStateToProps parameter supplied by connect (). It lets you use a selector function to pull data from the Redux store state.

The major difference between the Hook and the argument is that the selector may return any value as a result, not just an object.
1. Open the ViewNotes.js file
2. Import this Hook from react-redux

// …after rest of the imports
import { useSelector } from ‘react-redux’

Next, inside the ViewNotes functional component, instead of saving a notes array with the useState Hook, replace it with the following:

const notes = useSelector(state => state)

Dispatching actions

The useDispatch() Hook entirely refers to the Redux store’s dispatch function. This Hook is only used when an action has to be sent. Import it from react-redux, along with the addnote and deletenote actions from the redux/notesApp.js file.

import { useSelector, useDispatch } from ‘react-redux’

After the useSelector Hook, define the following sentence to dispatch an action:

const dispatch = useDispatch()

Next, to trigger these events, dispatch two operations named addNote and deleteNote:

const addNote = note => dispatch(addnote(note))
const deleteNote = id => dispatch(deletenote(id))

Because the naming convention for the addNote action is identical to that of the previous post’s helper function, there is no need to make any modifications inside the functional component’s return statement for this. But, the deleteNote action is brand new.

Add a prop onPress to List to remove a note from the displayed list. React-native-paper item UI component. This will provide the capability of removing an item from the list when the user touches it.

Below is the code snippet of List.Item component with changes. Also, ensure to modify the values of props: title and description.

<List.Item
  title={item.note.noteTitle}
  description={item.note.noteValue}
  descriptionNumberOfLines={1}
  titleStyle={styles.listTitle}
  onPress={() => deleteNote(item.id)}
/>

The advantage of  useDispatch hook is that it replaces mapDispatchToProps. Also it is not required to write boilerplate code to bind action creators with this hook now.

Conclusion

Other hooks like useDispatch and useSelector Redux not only minimise the need to create a lot of boilerplate code, but they also give the benefits of utilising functional components. Hence, while redux assists us in managing application state, this does not imply that you should use Redux in all of your projects. Other methods for handling state in our application include react-context, mobx, and libraries. But, before diving into the Redux components, it’s a good idea to brush up on your application development fundamentals. If the app state is regularly updated, and the logic to update that state is complicated, you might consider utilising redux. The programme has a medium or big codebase and may be worked on by a large number of individuals. You must examine how that condition changes throughout time.

The post How to Use Redux with React Hooks in React Native Application appeared first on Talent500 blog.

In recent times, React has received a lot of attention due to its relatively shallow learning curve. But following the best practices and industry standards is what most developers lack. Most likely, you will work with a  team of React developers. In order to work as a team, you need to follow some semantics and patterns that everyone can understand. Your code should be maintainable and reusable. If you have hundreds of components, managing your application will be difficult if you don’t follow some patterns.

In this detailed blog, we will cover various best practices while coding in React as well as some design patterns that you should know as a React developer. So let’s get started!

File organization in React

When working with React, you will have many files and folders in your project directory, it is recommended to have distinct folders so that your application can be maintained.

React folder structure

There is no one best file structure, but it is important to keep your files organized. Every component in React has at least one file associated with it, so your file structure will grow rapidly. Organize CSS, images, and fonts in a folder called assets. 

Naming convention in React

The naming of files and folders is one of the simplest tasks a developer can perform. Nevertheless, it is a very important one. Having a well-named file or folder can make it easier for you and other developers to find and understand your code.

When naming files and components, we often use Pascal Case or Camelcase. There are still a variety of cases developers use, such as the kebab case, the snake case, etc.

Different text cases

Reusable components

React is known for its ability to handle large components. However, if we break them into smaller pieces, we can reuse them. Reading, testing, maintaining, and reusing small components is easier. 

You can create a component, such as a widget, and import it on all the other components you require, eliminating the need for duplicate code. You can increase a component’s ability to be reused by designing it with a single function. 

Maintain a structured import

Since React is not an all-encompassing library, if you are a React developer, you are already aware that we import a lot of community libraries. We also import various style files, utils files, component files, and other files as necessary. The import section needs to maintain a sensible organizational structure or group in order to keep the code readable and maintainable.

React import structure

Remove unnecessary comments from the Code

It is important that the code we write is self-explanatory and not limited only to React.Make sure you only add comments where they are needed in order to avoid confusion when changing the code in the future. While going through the production, remove any unnecessary code such as console.logs(), alerts(), and other unused codes.

Stateless function

Defining highly reusable components using stateless functions is a brilliant idea. There is no state in them; they are only functions.

Stateful component

Components that store state are referred to as stateful components. Class components or functional components with hooks are both examples of stateful components. It is also called a container component, i.e, a container does data fetching and then renders its corresponding sub-component.

JSX spread attributes

Spread attributes are a JSX feature. It is syntactic sugar for passing every property of an object as JSX attributes. We can quickly copy all or a portion of an existing array or object into another array or object using the JavaScript spread operator (…).

Do not define a function inside render.

The tendency of React developers to define or create functions inside the render frequently leads to unexpected errors. It’s best to avoid defining a function inside the render. Try to keep the logic inside the render to an absolute minimum.

Destructuring

The destruction shown assigns properties of an object to variables of the same name. The destructuring assignment syntax is a JavaScript expression that makes it possible to unpack values from arrays, or properties from objects, into distinct variables.

Index as keys

React requires you to add a key prop to your element when creating an array of JSX elements. This is commonly done via a map function which in turn results in people using the index which is returned and set to the key property. This is an anti-pattern!
Arrays are collapsible, so React uses the key property to track each element. This can easily result in incorrect information being displayed.
Keys help React identify which items have changed, are added, or are removed. Keys should be given to the elements inside the array to give the elements a stable identity.

Unnecessary divs should be avoided.

React developers tend to use divs to wrap the entire component, and sometimes it is not a good idea to follow this approach.

An alternate way of doing this is using a fragment, <React.Fragment> was introduced in React v16.2, we can use them instead of the several <div> tag.

Always name the components

It is recommended to have names for the components. Some new React developers have a bad habit of creating components without giving them names. You should always give names to the components. Utilizing React Dev Tools will enable you to track the error.

Conditional rendering

In React, you can create distinct components that encapsulate the behavior you need. Then, you can render only some of them, depending on the state of your application. Conditional rendering in React works the same way conditions work in JavaScript.
You can’t use regular if/else conditions inside a component definition. You can use the ternary operator to achieve the same.

Here are some examples of condition rendering in action:

If

Unless

If else

Avoid nested Ternary Operators

Ternary operators are useful when we want to render something based on certain conditions. It is ideal for small cases, but when we nest ternary operators for checking more than one condition, it makes the code complex and hard to maintain.

Children types

React can render child components of many types. In most cases, it’s either an array or a string.

String

Array

Function

Array as children

We can iterate over an array, and we can provide an array as children. This is one of the common patterns in React. We can use the JavaScript map method to iterate through the elements for every value!

Function as children

Functions as child components let you pass a render function as the children prop to a component, allowing you to change what can be passed as children.

Unidirectional data flow

One-way direction data flow eliminates multiple states and deals with only one which is usually inside the store. To achieve that, our Store object needs logic that allows us to subscribe for changes.

Controlled and uncontrolled input

An input form element whose value is controlled by React is called a controlled component. A controlled input accepts its current value as a prop, as well as a callback to update that value, that’s the point of React.

Uncontrolled input is like traditional HTML form input:

A form element becomes “controlled” if you set its value via a prop. Controlled states are preferred over uncontrolled ones as they are easier to manage.

Accessing a Child Component

DOM elements and React elements you create yourself can be accessed by React references.

Mutating State without setState()

When we try to change the state of our component without using setState() it causes state changes without making the component re-render. Whenever setState gets called in the future, the mutated state gets applied.

Spreading props on DOM elements

When we spread props, we run into the risk of adding unknown HTML attributes, which is a bad practice. We usually spread the properties to the elements to avoid writing every single one manually.

So far, so good, but spreading props into an HTML DOM element is a bad practice.

The above code will give an error, just like the one given below, because the div element has no property called foo:

There are many more React patterns and antipatterns that you will find if you dig a little deeper. One thing to note is that we should also follow the semantic structure, for example, using semantic HTML tags like “section, “article,” etc. 

Wrapping It Up!

Congratulations on reaching this far! You’re a fantastic reader! In this detailed blog, we looked at various patterns that we should follow while using React. Not only did we experiment with React, but we also discussed various best practices and how to implement them with simple snippets.

Now you know how to build your React application in the most effective and efficient way.

A list of the 10 best backend frameworks for mobile app development should be the best place to start. For frontend, you can check our blog post for essential tools for faster frontend development. In this blog, we will not only cover and explore what backend development is and what the top backend frameworks are, but also how these frameworks would impact your mobile app development project. 

What is a mobile app backend?

The mobile app backend framework is the backbone of your app and lives on the server. It helps create and manage all essential services in the background function of a mobile or web app. A database, web server, operating system, framework, and server-side languages such as Python, PHP,.Net, Swift, Objective-C, JavaScript, Ruby, Kotlin, C#, C++, GO, and Dart are examples of back-end components.

Best Mobile App Backend Framework in 2022-23

According to Statista, smartphone users are expected to reach 7.5 billion by 2026.

Following these expectations, mobile app development has become one of the most profitable business opportunities in recent years. Many developers are seeking the best framework to build their mobile apps, due to the growing demand for them. To address their challenges, in this section we will discuss the most popular framework for mobile backend development, and how it can help you build apps with its amazing features and functionalities.

 Here is the list of the best mobile app backend frameworks for 2022–2023.

1.NodeJS

NodeJS is the most popular backend framework for mobile app development. It is a cross-platform, server-side JavaScript environment that can be used to build scalable and high-performance web applications. It has an extensive collection of modules that can be used to build applications, and it’s also fast, scalable, and lightweight.

NodeJS was created by Ryan Dahl and TJ Holowaychuk, who were looking for a way to create their own server-side scripting language. With Node JS, developers are able to write JavaScript on both the client and server sides. In real-time applications, this enables data transfer between the server and the client, thereby enabling synchronisation.

Features of NodeJS include: 

1. Suitable for cross platform mobile applications development 
2. Easier development process
3. Code reusability and code sharing 
4. Backed by leading companies 2.1% of all websites
5. Asynchronous handling of requests
6. The availability of free tools

2. Express JS

Express JS is a lightweight framework for building web applications. It is built on top of Node.js and uses the CommonJS module system, which makes it easy to use in any JavaScript project. It also has lots of features, such as routing, validation, tagging, and more, that make it a good choice for building RESTful APIs.

In addition to its many useful features, Express JS has also been gaining popularity since its inception, by John McCrate as part of his course at Front End Masters (now Creative Coding).

Features of Express js

• Server-side development that is faster Features for developing web and mobile applications
• A layer built on top of Node js helps managing servers and routes.
• It enables developers to create APIs and web applications with ease
• Makes it easier to identifies bug areas

3. React Native

Known as an open-source, cross-platform app development framework, React Native was introduced by Facebook in 2018. It has been developed and maintained by the tech giant since its release. In addition, React Native simplifies iOS and Android app development, which plays a significant role in its popularity. There are a number of popular applications based on the React Native framework, such as Amazon Prime, Tesla, Skype, Airbnb, and so on.

Features of React Native include:

• Compatibility with third-party plugins
• Reusable components
• Superior performance
• It supports both iOS and Android.

4. Flutter

Flutter is an open-source framework developed by Google for creating cross-platform applications using one codebase. With its innovative design strategy for designing applications that have a native-like appearance and feel, this SDK is an excellent tool for building cross-platform applications. It is often the best choice for mobile app developers to create an engaging application with a highly reliable mobile user interface quickly.

The Flutter framework offers widgets, a rendering engine, testing, and a number of other tools to let programmers create and develop visually appealing mobile apps. Flutter technology is used by reputable companies, such as Alibaba, Google, and Abby Road Studios.

Features of the Flutter framework:

• powerful widget support
• Streamlining the development process
• highly reliable mobile user interface
• in-built material design
• Rich motion APIs
• high-performance app similar to native

5. Laravel

Laravel is definitely one of the most popular PHP frameworks to use and is ideal for all types of applications, especially custom requirements such as portal mobile apps, social media apps, It offers predefined templates that enable a quick and time-saving mobile app development process. For mobile developers, it creates a simpler backend development process, which makes it easy to meet the feature requirements of the user.

Though Laravel isn’t the only PHP framework, if you have already used it, you might use other popular PHP frameworks like CodeIgniter, CakePHP, or Zend Frameworks.

It includes the following features:

• Simpler backend development
• OPen-source framework 
• Quick and easy to market
• Enhanced security 
• Community support 

6. .NET MAUI (formerly known as Xamarin)

Xamarin has been a leading open-source, cross-platform application platform for the development of high-performance mobile apps for iOS, Android, and Windows since its introduction in 2011. The platform was deprecated in November 2021. It was eventually replaced by.NET MAUI (.NET Multi-Platform App UI), which is used by businesses across industries to create scalable and performant cross-platform Android and iOS apps.

“As per the survey, more than 15,000 organizations and 1.4 million programmers were using Xamarin.” The framework’s apps have an average market share of 1.88%, with business-related apps having the highest market share at 6.54%. 

The stats only highlight the popularity of Xamarin; developers can try out the new.NET MAUI to stay updated with its new versions.

7. Loopback

Loopback is a Node.js framework for creating APIs. It has an ORM, a CLI, and a REST API generator that generates all of the code you need to create your app’s APIs.

Loopback was originally created by the team behind Express and can be used with any database, so it’s easy to integrate into your existing projects if you have one (like MySQL). The core of Loopback is built on Express, but it includes more than just this framework; it also includes other useful modules such as form validation and authentication integration, making Loopback incredibly flexible when it comes to building apps in addition to APIs!

• Makes it easy to handle data in a persistence system
• Designed to create APIs and connecting them with backend data sources
• TCP loopback optimization to a low-latency loopback path for performance-critical applications
• Availability of offline data access and synchronization

8. Django

Developed in Python, Django is a free, open-source framework based on a model-view-template architecture. Django is designed by experienced developers to develop better web apps more quickly and with fewer lines of code. As well as taking away much of the hassle of web development, so you can focus on writing your app rather than reinventing the wheel. 

It is maintained by the Django Software Foundation (DSF), an independent organisation established to advance the Django software and its community. 

Django offers features such as:

• Exceptionally scalable 
• Designed to drive faster, clean and pragmatic development cycles
• Advance the state of the art in Web development.
• Protect the intellectual property and the framework’s long-term viability.

9. Ruby on Rails

A model-view-controller framework, Ruby on Rails is a Ruby-based open-source framework for developing web applications. This means that it separates your application into three main parts: models (representing data), views (displaying that data), and controllers (controlling the flow of your application).

Rails has become extremely popular because of its ease of use and flexibility. It allows developers to quickly build complex applications with minimal overhead, making them ideal when you need something fast but still want something robust enough to handle larger loads or more complex needs.

Features of Ruby on Rails include:

• Allow easy changes in codes for 
• Extremely scure server side web application 
• Database-backed web applications according to MVC pattern 
• Clean and easy to learn syntax for developers
• More organized and Object oriented 

10. Spring Boot

Spring Boot is a microservices framework that takes care of most of the boilerplate work for you. It’s designed to help you build fast, production-ready applications using only the features you need and none of the ones you don’t.

Spring Boot provides an opinionated set of features out of the box:

• a Maven repository with many pre-packaged dependencies, including spring-boot-starter, springfox, and orocrudus (more on these later).
• a simple configuration file that defines all your application’s dependencies, startup classes, and service definitions in one place.

This makes it easy for developers who already know how to use a tool like Gradle or Maven but haven’t had much experience with Java yet, because they’re not required to learn anything new!

Conclusion

Choosing the right mobile app backend framework isn’t always easy, so we’ve put together this handy guide on what makes for great software development tools for developers working on your next project!

This post describes the top mobile app backend development frameworks that help you build apps with amazing features and functionalities. However, it’s important to realise that there are many good choices for building a mobile app backend. You can use one of the frameworks listed above, or you can create your own custom one. If you’re new to developing apps, this article will help you decide which framework is best for your project’s needs.

In this detailed blog, we will look into the various methodologies that we should follow to get our web application up and running.

So let’s get started.

The Ideation stage

Having an idea for your application is the first step in developing your web application. You should be aware of the problem your application is trying to solve and whether it will remain viable over the coming years. However, the real question is: what kind of application do you want to create?

Today, a wide variety of web applications are available; let’s examine some of them.

Static web pages: These are the types of web pages that are rarely updated, and all of the files are prebuilt so that when the user requests something, it will respond with media, text, or whatever it is that the user is looking for. These are mostly websites for resumes, brochures, or static business landing pages.

Single-page applications: Instead of using the standard procedure of having a web browser load entirely new pages, a single-page application dynamically rewrites the current web page with fresh information from the web server to interact with the user.

Dynamic web applications: Dynamic websites are designed to deliver and display the content of each page dynamically, or on-the-fly, based on user behavior or content generated by users.

Additionally, there are several decisions that you need to make at this stage, such as whether we need server-side rendering or client-side rendering. Even in the development stage, some decisions have to be made.

Design and Development stage

At this stage, we develop some features, break things down and determine what needs to be changed, which stack to use, etc.

Website development begins with a design, and web designers use tools such as Figma, Canva, or Photoshop to create mockups for the design. And now that we’ve decided on a design, the real fun begins.

In the blog, I mentioned that we have several decisions to make about the tools and frameworks we should use. Now is the time we actually decide those things. We need HTML and CSS at the very basic level, but using just those will be difficult if we have a huge application. We have to select the front-end tools, back-end tools, and databases suitable for our application.

Which frontend tools and technologies should you use?

Currently, JavaScript is the only language that web browsers understand(using web assembly, we can use other languages). And as it happens, there are a lot of JavaScript front-end libraries and frameworks. We will look into some of the popular JavaScript libraries for our aid:

React JS

 React is a widely preferred front-end UI library used in nearly 50 million projects every month. React, which is backed by Facebook, has dominated the web development space for over nine years and has several notable customers ranging from startups to Fortune 500 companies. 

Plainness and flexibility are the two primary reasons that contribute to React’s growing popularity. React can be used for both small-scale and large-scale applications, and it will work well in both cases.

Angular JS

AngularJS, which was developed by Adam Abrons and Misko Hevery in 2008-2009, is now maintained by Google. AngularJS is an open-source Javascript framework that primarily facilitates the development of single-page web applications (SPAs). Web application development is made easier with this framework’s continuous growth and expansion.

Vue JS

VueJS is a progressive JavaScript framework for developing interactive web interfaces. The front-end part of the application is more focused on the view. There is no problem integrating it with other projects or libraries. The installation of VueJS is fairly simple, and beginners can easily understand and start building their own user interfaces. The ideal user experience is Vue. js’s main feature, which it achieved by combining React and Angular’s top-level features. Additionally, it improved the code structure and made use of the virtual DOM’s capabilities.

Other frameworks include Svelte, Hydrogen, Preact, Laravel, and others. You can choose any of those that fit well for the application.

When it comes to styling, we have several CSS frameworks that can help us with styling. A few of these are CSS-in-JS libraries, styled-components, independent frameworks, and so on. We will now look into some of those:

Tailwind CSS

Tailwind CSS is an open-source utility-first CSS framework that makes it easy to apply excellent styling to your React web application by choosing from the framework’s ready-made CSS classes. Tailwind CSS  gives you the creative control to create dynamic components—which means you can tweak the values of properties to make highly customizable UI components.

Bootstrap

Bootstrap is an open-source toolkit for developing responsive websites and applications. Bootstrap is a suite carrying a collection of HTML, CSS, and JavaScript toolkits for creating websites. The Bootstrap Grid system helps you to create your layout and easily build a responsive website.

There are many more CSS frameworks, but these two are popular among developers these days, and you are not limited to just these. You can pick other frameworks like Foundation, Bulma, Material CSS etc.

With a better understanding of the front-end tools to use, we can now check out the languages and libraries for the back-end development of your web application.

Which backend languages and libraries should you use?

The frontend is the visual part of your application, and the backend is the logic part of your application. You should implement your logic in such a way that it won’t result in any kind of security flaws, overloading , authentication and authorisation of users, etc. There are several choices of language and libraries, and we can check those out:

JavaScript

Given that your frontend is likely to use JavaScript and that having both codebases in JavaScript makes switching easier for developers, JavaScript is one of your best options for the backend.

Since JavaScript is only supported on browsers, we need a server environment to run JavaScript code. For this purpose, we use node.js, a JavaScript runtime environment. Node is an open source environment for creating server-side and networking applications. Node.js programs are written in JavaScript and executed by the Node.js runtime on Linux, OS X, and Microsoft Windows.

In order to work with NodeJS, we use the ExpressJS library. Express is a flexible web application framework for Node.js that offers a strong set of features for both web and mobile applications.

Python

Another excellent choice for backend development is Python.With built-in libraries that can be used for almost any programming task, Python comes with a wide range of features by default. Python helps developers by providing them with solutions that they would otherwise have to create manually, saving them time and effort on everything from scientific calculations to image processing, operating system interfaces, and protocols.

One of the most used Python libraries for web applications is Django. Making effective web applications quickly is possible with Django. Because Django includes built-in features for everything, including the Django Admin Interface and the default database, SQLlite3, it is also known as a “batteries included” framework.

Flask is another well-liked Python library. Flask is a web development framework. It is a framework with an integrated debugger and development server.

Thanks to the Flask framework, web developers are able to be flexible and easily accommodate the frequently released changes in the software development community, which sets it apart from other archetypes.

Golang

The best elements of several other programming languages are combined in Go. For example, it performs well like C/C++ and Java and is useful for a variety of tasks like Python. It has excellent scalability, advanced memory safety, concurrency, dynamically formatted interfaces, and dynamic formatting. These characteristics make this language the ideal choice for cloud interfaces, network apps, and microservices.

There are numerous backend languages, including Java, C, C++, and C#. According to stackoverflow, the most popular backend languages are JavaScript, Python, and Go. Now that we are aware of the backend development languages, we can check out the various databases that we can use to store our web application data.

Which Databases should you use for your application?

A database is a structured collection of data that is typically stored electronically in a computer system. In most cases, a database management system is in charge of a database. When it comes to databases, there are only two main options: SQL and NoSQL databases.

SQL

When creating, maintaining, and retrieving data from relational databases, Structured Query Language, also known as SQL, is used. In a relational database, data is stored in one or more tables  of columns and rows, making it simple to see and comprehend how various data structures relate to one another. Data is organized in relational databases according to predefined relationships.

Some of the most popular SQL databases are MySQL and Microsoft SQL. Due to their increased stability and ability to guarantee data integrity, SQL databases are a better fit for demanding or complicated transactions. You must make sure of ACID compliance (Atomicity, Consistency, Isolation, Durability) or define exactly how transactions interact with a database.

NoSQL

NoSQL databases store data differently from relational tables because they are not tabular databases. Depending on the data model, there are different types of NoSQL databases. Document, key-value, wide-column, and graph are the main types. With a lot of data and a lot of users, they scale well and offer flexible schemas.

Some of the most popular NoSQL databases are MongoDB, DynamoDB, Firebase Firestore. NoSQL is ideal to use if we are constantly adding new features, functions, and data types and also when we can trade-off data consistency and integrity.

We now have some ideas for the databases you should use to store the data component of your application. It’s time to test our web application now.

Testing Your Web Application

Prior to going live and becoming publicly accessible, web testing, also known as website testing, involves checking your web application or website for potential bugs. Web testing examines the website or web application’s performance, compatibility, security, and usability.

The following list includes some of the website testing checklists:

Functional testing: Testing the functionality of a website’s user interface, APIs, databases, security, clients, servers, and other fundamental features is referred to as functional testing.

Usability testing: It  is an essential component of any web-based project. It can be conducted by testers like you or a small focus group that represents the web application’s target market.

Interface Testing:  A type of software testing that examines the effectiveness of communication between two various software systems.

Database Testing: A subset of software testing that examines the structure, tables, triggers, and other components of the database that is being tested. 

There are numerous additional tests like security testing, performance testing etc.,that you can run to make sure your web application is functioning as expected and won’t break in use.

These are the fundamental steps for building a web application from scratch. 

Scaling the web application will be another requirement after the web application becomes successful. Scalability is an application’s ability to maintain consistent performance regardless of how many people use it at the same time. As a result, a big-scale web app is one that can manage massive amounts of data and traffic while also adapting to significant load variations without compromising operational quality. 

You can scale your web application by reducing server demand, employing caching engines like Redis, scaling the server, and other methods.
