How to implement Queue data structure in the ReactJS ?

We’ll explore the implementation of a basic queue data structure in a React application using the “rooks” library. Queues are fundamental in computer science and find applications in various scenarios, including task scheduling, handling requests, and managing data flow.

Prerequisites:

• NodeJS or NPM
• React JS
• Queue Data Structure

Approach:

This React component uses the useQueueState hook from the “rooks” library to manage a queue of numbers.

• The numberToPushRef is a useRef that keeps track of the number to be pushed into the queue.
• The addToQueue function increments the value in numberToPushRef and enqueues the updated value.
• The UI includes buttons for enqueueing and dequeuing, displaying the front element, and showing the length of the queue.
• Styling is applied using inline styles for simplicity.

Steps to Create the React Application And Installing Module:

Step 1: Create a React application using the following command:

npx create-react-application demo

Step 2: After creating your project folder i.e. demo, move to it using the following command:

cd demo

Step 3: Install Rooks from npm.

npm i rooks

Project Structure:

Project Structure

The updated dependencies in package.json file will look like:

"dependencies": {
    "react": "^18.2.0",
    "react-dom": "^18.2.0",
    "rooks": "^7.14.1",
    "react-scripts": "5.0.1",
    "web-vitals": "^2.1.4",
}

Example: In this example, we’ll implement the data structure queue in the React JS:

Step to Run Application: Run the application using the following command from the root directory of the project:

 npm start

Output: Now open your browser and go to http://localhost:3000
