We can show upload or download percentage in ReactJS using the CircularProgress Component with some core logic to show percentage. Material UI for React has this component available for us, and it is very easy to integrate. We can do it the 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 Box from '@material-ui/core/Box'; import CircularProgress from '@material-ui/core/CircularProgress';   export default function App() {     const [uploadOrDownloadCount,          setUploadOrDownloadCount] = React.useState(10);     React.useEffect(() => {     const timer = setInterval(() => {       setUploadOrDownloadCount(         (beforeValue) => (beforeValue >= 100 ? 0                           : beforeValue + 10));     }, 800);     return () => {       clearInterval(timer);     };   }, []);     return (     <div>       <h4>How to show upload/download percentage in ReactJS?</h4>       <Box position="relative" display="inline-flex">         <CircularProgress variant="determinate"                           value={uploadOrDownloadCount} />         <Box           bottom={0}           right={0}           top={0}           justifyContent="center"          left={0}           display="flex"          alignItems="center"          position="absolute"        >           {`${Math.round(uploadOrDownloadCount)}%`}         </Box>       </Box>     </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.
