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

http.createServer(function (req, res) {
  var path = 'video.mp4';
  var stat = fs.statSync(path);
  var total = stat.size;
  if (req.headers['range']) {
    var range = req.headers.range;
    var parts = range.replace(/bytes=/, "").split("-");
    var partialstart = parts[0];
    var partialend = parts[1];

    var start = parseInt(partialstart, 10);
    var end = partialend ? parseInt(partialend, 10) : total-1;
    var chunksize = (end-start)+1;
    console.log('RANGE: ' + start + ' - ' + end + ' = ' + chunksize);

    var file = fs.createReadStream(path, {start: start, end: end});
    res.writeHead(206, { 'Content-Range': 'bytes ' + start + '-' + end + '/' + total, 'Accept-Ranges': 'bytes', 'Content-Length': chunksize, 'Content-Type': 'video/mp4' });
    file.pipe(res);
  } else {
    console.log('ALL: ' + total);
    res.writeHead(200, { 'Content-Length': total, 'Content-Type': 'video/mp4' });
    fs.createReadStream(path).pipe(res);
  }
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');

It works! But I have one question,

Can I save the current time ends my video in my Javascript? I need to save the current time when start the video in my navigator and when finished the video in the navigator or when I close my navigator.

Nice work. i need to prevent download option on videos in all browser to the users.

can please help

You're using a sync method using Node.js. That's probably the worst thing you could do since the whole process hangs while .statSync() gets invoked.

Hi @paolorossi.
Thanks for share your code. I want to ask to you a question!
How to prevent download video when streaming for user? Thanks!

How would be a live stream? I mean, this way every time you open "localhost:port", it plays the file from the beginning over again
