How to download audio file from URL in Node.js?

Question

How to download audio file from URL and store it in local directory? I'm using Node.js and I tried the following code:

var http = require('http');
var fs = require('fs');
var dest = 'C./test'
var url= 'http://static1.grsites.com/archive/sounds/comic/comic002.wav'
function download(url, dest, callback) {
  var file = fs.createWriteStream(dest);
  var request = http.get(url, function (response) {
    response.pipe(file);
    file.on('finish', function () {
      file.close(callback); // close() is async, call callback after close completes.
    });
    file.on('error', function (err) {
      fs.unlink(dest); // Delete the file async. (But we don't check the result)
      if (callback)
        callback(err.message);
    });
  });
}

No error occured but the file has not been found.

It doesn't look like you actually call the `download` function, so nothing is happening. — Karl Reid, May 05 '17 at 17:31
Why do you have `'` character before var and then the last line `}'` ? — bhantol, May 05 '17 at 17:45

Duplicate of How to download a file with Node.js (without using third-party libraries)?, but here is the code specific to your question:

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

var file = fs.createWriteStream("file.wav");
var request = http.get("http://static1.grsites.com/archive/sounds/comic/comic002.wav", function(response) {
  response.pipe(file);
});

does `fs.createWriteStream("file.wav")` create a file on the server? or does it just make it available to send back to client? – user1063287 Jul 14 '19 at 03:45
@user1063287 no, `fs.createWriteStream("file.wav")` does not create a file on the server. it opens a write stream to a file, which means that as bytes slowly come in from somewhere (the server), we have told the computer to let these bytes trickle into the hard drive _as they arrive_ (file.wav). – Gabe Rogan Jul 15 '19 at 10:05

Your code is actually fine, you just don't call the download function. Try adding this to the end :

download(url, dest, function(err){
   if(err){
     console.error(err);
   }else{
     console.log("Download complete");
   }
});

Also, change the value of dest to something else, like just "test.wav" or something. 'C./test' is a bad path.

I tried it on my machine and your code works fine just adding the call and changing dest.

Here is an example using Axios with an API that may require authorization

const Fs = require('fs');
const Path = require('path');
const Axios = require('axios');

async function download(url) {
    let filename = "filename";
    const username = "user";
    const password = "password"
    const key = Buffer.from(username + ':' + password).toString("base64");
    const path = Path.resolve(__dirname, "audio", filename)
    const response = await Axios({
        method: 'GET',
        url: url,
        responseType: 'stream',
        headers: { 'Authorization': 'Basic ' + key }
    })
    response.data.pipe(Fs.createWriteStream(path))
    return new Promise((resolve, reject) => {
        response.data.on('end', () => {
            resolve();
        })
        response.data.on('error', () => {
            reject(err);
        })
    })
}
