Example 1: download image in nodejs

const request = require('request');
const fs = require('fs');

async function download(url, dest) {

    /* Create an empty file where we can save data */
    const file = fs.createWriteStream(dest);

    /* Using Promises so that we can use the ASYNC AWAIT syntax */
    await new Promise((resolve, reject) => {
      request({
        /* Here you should specify the exact link to the file you are trying to download */
        uri: url,
        gzip: true,
      })
          .pipe(file)
          .on('finish', async () => {
            console.log(`The file is finished downloading.`);
            resolve();
          })
          .on('error', (error) => {
            reject(error);
          });
    })
        .catch((error) => {
          console.log(`Something happened: ${error}`);
        });
}

// example

(async () => {
  	const data = await download('https://random.dog/vh7i79y2qhhy.jpg', './images/image.jpg');
  	console.log(data); // The file is finished downloading.
})();

Example 2: node js download file to folder

var http = require('http');
var fs = require('fs');

var download = function(url, dest, cb) {
  var file = fs.createWriteStream(dest);
  var request = http.get(url, function(response) {
    response.pipe(file);
    file.on('finish', function() {
      file.close(cb);  // close() is async, call cb after close completes.
    });
  }).on('error', function(err) { // Handle errors
    fs.unlink(dest); // Delete the file async. (But we don't check the result)
    if (cb) cb(err.message);
  });
};
