download a file nodejs

1. Use the fs module to require the built-in Node.js file system module:

const fs = require('fs');

1. Use the https or http module to make a GET request to download the file from a URL:

const https = require('https');
const fileUrl = 'https://example.com/file.zip';

1. Create a writable stream using fs.createWriteStream to save the downloaded file locally:

const file = fs.createWriteStream('file.zip');

1. Use https.get or http.get to initiate the GET request and save the response to the file stream:

https.get(fileUrl, function(response) {
  response.pipe(file);
});
