Electron Chromecast

An implementation of the chrome.cast API in electron

Usage

Basic

You must consume electron-chromecast from within your renderer process, preferably in a preload script.

// ES5
require('electron-chromecast');

// ES6
import 'electron-chromecast';

This will inject the chrome.cast variables and the associated methods globally automatically.
By default when requesting a new Session through chrome.cast.requestSession you will be provided an active Session with the first Chromecast Device we find. To change this behaviour read the Advanced section.

Advanced

// ES5
var chromecast = require('electron-chromecast');

chromecast(function (receivers) {
    return new Promise(function (resolve, reject) {
        // Do some logic to choose a receiver, possibly ask the user through a UI
        var chosenReceiver = receivers[0];
        resolve(chosenReceiver);
    });
});

// ES6
import chromecast from 'electron-chromecast';

chromecast((receivers) =>
    new Promise((resolve, reject) => {
        // Do some logic to choose a receiver, possibly ask the user through a UI
        const chosenReceiver = receivers[0];
        resolve(chosenReceiver);
    });
);

The function returned from electron-chromecast should be called with a single parameter; a function that returns a promise that will eventually resolve with a single receiver. This receiver is the one that will be used by chrome.cast.

Installation

Note: Behind the scenes we use MDNS which has some system requirements, make sure your system has the required dependencies.

• All the TODO's in code (We only implemented the functionality required by Google Play Music, however this should be sufficient for MOST applications)
