A Chromecast client based on the new (CASTV2) protocol

This module implements a Chromecast client over the new (CASTV2) protocol. A sender app for the DefaultMediaReceiver application is provided, as well as an Application base class and implementations of the basic protocols (see the controllers directory) that should make implementing custom senders a breeze.

This implementation tries to stay close and true to the protocol. For details about protocol internals please see https://github.com/thibauts/node-castv2.

For advanced use, like using subtitles with the DefaultMediaReceiver check the wiki.

Installation

$ npm install @amilajack/castv2-client

On windows, to avoid native modules dependencies, use

$ npm install @amilajack/castv2-client --no-optional

Launching a stream on the device

import { Client } from 'castv2-client';
import { DefaultMediaReceiver } from 'castv2-client';
import mdns from 'mdns';

browser.on('serviceUp', service => {
  console.log('found device "%s" at %s:%d', service.name, service.addresses[0], service.port);
  ondeviceup(service.addresses[0]);
  browser.stop();
});
 
browser.start();
 
function ondeviceup(host) {
 
  const client = new Client();
 
  client.connect(host, () => {
    console.log('connected, launching app ...');
 
    client.launch(DefaultMediaReceiver, (err, player) => {
      const media = {
 
       // Here you can plug an URL to any mp4, webm, mp3 or jpg file with the proper contentType.
