pychromecast-node-wrapper

You're probably asking yourself "why not rewrite pychromecast in node ?". Heh well..., the interface protocol for Google Chromecast devices isn't that well documented and the folks behind pychromecast made a great work at reverse engineering the Chromecast protocol. Pychromecast is popular and well maintained, so my library's purpose is only to expose some actions from pychromecast to the js world.

Install

npm i pychromecast-wrapper
pip install -r node_modules/pychromecast-wrapper/requirement.txt

If something goes wrong during installation, something around mdns and node-gyp, take a look at mdns#installation and install missing system package.

Usage and Exemple

const { Chromecast } = require('pychromecast-wrapper')

(async () => {

  // Wait for discovery to do its work
  await new Promise(resolve => setTimeout(resolve, 1000))

  // Set all dsicovered chromecast volume
  await Chromecast.setVolume({ volume: 0.5 })

  // Find chromecast with a given name and toggle mute status
  const chromecast = Chromecast.findOne({ name: 'My Chromecast' })
  await chromecast.toggleMute()

})()
