React-Bootstrap ProgressBar Component

React-Bootstrap is a front-end framework that was designed keeping react in mind. ProgressBar Component provides a way to show the progress of any tasks/activity to the user in the form of the progress bar. We can use the following approach in ReactJS to use the react-bootstrap ProgressBar Component.

ProgressBar Props:

• animated: It is used to apply the stripe animation to our ProgressBar component.
• children: It is used to allow only Child elements.
• isChild: It is of boolean type and indicates whether the element is a child member or not.
• label: It is used to show a label that represents a visual percentage.
• max: It is the maximum value that progress can reach.
• min: It is the minimum value that progress can begin from.
• now: It is used to indicate the current value of progress.
• srOnly: It is used to hide the label visually.
• striped: It is used to create a striped effect.
• variant: It is used to set the background class for our progress bar.
• bsPrefix: It is an escape hatch for working with strongly customized bootstrap CSS.

Creating React Application And Installing Module:

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

npx create-react-app foldername

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

cd foldername

Step 3: After creating the ReactJS application, Install the required module using the following command:

npm install react-bootstrap 
npm install bootstrap

Project Structure: It will look like the following.

Project Structure

Example: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.

Filename: App.js

Javascript

import React from 'react';
import 'bootstrap/dist/css/bootstrap.css';
import ProgressBar from 'react-bootstrap/ProgressBar';

export default function App() {

  const [countOfProgess, setCountOfProgess] = React.useState(0);

  React.useEffect(() => {
    const timer = setInterval(() => {
      setCountOfProgess((oldProgress) => {
        if (100 == oldProgress) return 0;
        return Math.min(oldProgress + Math.random() * 10, 100);
      });
    }, 499);

    return () => {
      clearInterval(timer);
    };
  }, []);

  return (
    <div style={{ display: 'block',
                  width: 700, padding: 30 }}>
      <h4>React-Bootstrap ProgressBar Component</h4>
      Current Progress is: {parseInt(countOfProgess)} %
      <ProgressBar now={countOfProgess} />
    </div>
  );
}

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/, you will see the following output:
