A Linear progress bar shows the measure of progress of any task or activity Linearly. It is the graphical representation of linear progression. Material UI for React has this component available for us, and it is effortless to integrate. We can Create LinearProgress Bar in ReactJS using the following approach.
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 material-ui modules using the following command.
npm install @material-ui/core
App.js: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.
Javascript
import React from "react";import LinearProgress from "@material-ui/core/LinearProgress";Â
export default function App() {Â Â const [countOfProgress, Â Â Â Â Â Â Â Â Â setCountOfProgress] = React.useState(0);Â
  React.useEffect(() => {    const timer = setInterval(() => {      setCountOfProgress((oldProgress) => {        if (100 == oldProgress) return 0;        return Math.min(oldProgress + Math.random() * 10, 100);      });    }, 499);Â
    return () => {      clearInterval(timer);    };  }, []);Â
  return (    <div>      <h4>How to show LinearProgress in ReactJS?</h4>      <LinearProgress variant="determinate"                      value={countOfProgress} />    </div>  );} |
Step to Run Application: Run the application using the following command from the root directory of the project:
npm start
