chromecast-js

chromecast-js is a javascript client library for googlecast's remote playback protocol that uses DefaultMediaReceiver to play any (compatible) content in the Chromecast, it works by wrapping the node-castv2-client module.

From npm:

npm install chromecast-js

chromecastjs = require('chromecast-js')
 
var browser = new chromecastjs.Browser()
 
browser.on('deviceOn', function(device){
  device.connect()
  device.on('connected', function(){
 
    device.play('http://commondatastorage.googleapis.com/gtv-videos-bucket/big_buck_bunny_1080p.mp4', 60, function(){
        console.log('Playing in your chromecast!')
    });
 
    setTimeout(function(){
        device.pause(function(){
            console.log('Paused!')
        });
    }, 30000);
 
    setTimeout(function(){
        device.stop(function(){
            console.log('Stoped!')
        });
    }, 40000);

Subtitles and Cover

To include subtitles and a cover image with the media title, use an Object instead of a string in the play method:

 
chromecastjs = require('../')
 
var browser = new chromecastjs.Browser()
 
var media = {
    url : 'http://commondatastorage.googleapis.com/gtv-videos-bucket/big_buck_bunny_1080p.mp4',
