streaming mp3 using nodejs

mp3.js

var http = require('http'),
    fileSystem = require('fs'),
    path = require('path')
    util = require('util');

http.createServer(function(request, response) {
    var filePath = 'path_to_file.mp3';
    var stat = fileSystem.statSync(filePath);

    response.writeHead(200, {
        'Content-Type': 'audio/mpeg',
        'Content-Length': stat.size
    });

    var readStream = fileSystem.createReadStream(filePath);
    // We replaced all the event handlers with a simple call to util.pump()
    util.pump(readStream, response);
})
.listen(2000);

Ok now I can start a stream at anytime I like , but just by byte offset :/

@daslicht can you share the solution you found to start playback at a specific point?

good (Y)

@daslicht I'd like to see how you started playback at a specific point as well

I'm looking to do the same, is there a way to start the playback at a specific point in time? Any help would be greatly appreciated.

It was very useful, I'm working in a personal project and this code was a bless.

thanks! super helpful code

var http = require('http'),
    url = require('url'),
    fs   = require('fs'),
    filePath = '/home/risto/Downloads/oleg.mp3',
    stat = fs.statSync(filePath);

http.createServer(function(request, response) {
    var queryData = url.parse(request.url, true).query;
    const skip = typeof(queryData.skip) == 'undefined' ? 0 : queryData.skip;
    const startByte = stat.size * skip;

    response.writeHead(200, {
        'Content-Type': 'audio/mpeg',
        'Content-Length': stat.size - startByte
    });

    // We replaced all the event handlers with a simple call to util.pump()
    fs.createReadStream(filePath, {start:startByte}).pipe(response);
})
.listen(2000);

This gives you skipping ^^

Video stream with range.

var http = require('http'),
    url = require('url'),
    fs   = require('fs'),
    filePath = '/home/risto/Downloads/oleg.mp4',
    stat = fs.statSync(filePath);

http.createServer(function(request, response) {        
    const fileSize = stat.size;
    const range = request.headers.range;
    if (range) {
      const parts = range.replace(/bytes=/, "").split("-");
      const start = parseInt(parts[0], 10);
      const end = parts[1] 
        ? parseInt(parts[1], 10)
        : fileSize - 1;
      const chunksize = (end - start) + 1;
      const readStream = fs.createReadStream(filePath, { start, end });
      const head = {
        'Content-Range': `bytes ${start}-${end}/${fileSize}`,
        'Accept-Ranges': 'bytes',
        'Content-Length': chunksize,
        'Content-Type': 'video/mp4',
      };
      response.writeHead(206, head);
      readStream.pipe(response);
    } else {
      const head = {
        'Content-Length': fileSize,
        'Content-Type': 'video/mp4',
      };
      response.writeHead(200, head);
      fs.createReadStream(filePath).pipe(response);
    }
})
.listen(2000);

^^^ works like charm, thanks!
