Thank you for your reply! I have a node js application without an express server. Needed to make a request and get a file in the root of the project. Here is the code I needed.

const axios = require(‘axios’);
const fs = require(‘fs’);

axios({
method: ‘GET’,
url: ‘URL_request’,
responseType: ‘stream’
})
.then(response => {
const writer = fs.createWriteStream(‘file_name.mp3’);
response.data.pipe(writer);

writer.on('finish', () => {
  console.log('File successfully downloaded');
});

writer.on('error', err => {
  console.error('Error downloading the file:', err);
});

})
.catch(error => {
console.error(‘Error when executing the request:’, error);
});

the format is in ‘Content-Type’, ‘audio/mpeg’

If calling from browser this can directly play within chrome.
If you use in project like expressjs nodejs, you can do something like:

download mp3

const express = require('express');
const app = express();

app.get('/download', (req, res) => {
  // Simulated audio stream
  const audioStream = getAudioStreamFromEndpoint(); // Replace this with your endpoint to get the audio stream

  // Set the response headers
  res.set('Content-Type', 'audio/mpeg');
  res.set('Content-Disposition', 'attachment; filename="audio.mp3"');

  // Pipe the audio stream to the response
  audioStream.pipe(res);
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

Or directly steam it

 app.get('/audio', (req, res) => {
  // Simulated audio stream
  const audioStream = getAudioStreamFromEndpoint(); // Replace this with your logic to get the audio stream

  // Set the response headers
  res.set('Content-Type', 'audio/mpeg');
  res.set('Content-Disposition', 'inline');

  // Send the audio stream
  audioStream.pipe(res);
});
