Control Deck

An extensible node app for easily customizing an Elgato Stream Deck. Setup is all done via a JSON file and various Control Deck plugins.

Demo

Example

First, create a new app

mkdir myapp
cd myapp
npm install control-deck
npm install control-deck-media-controls
touch myapp.js
touch button-layout.json

Now configure our button layout in button-layout.json

{
	"button_0": {
		"plugin": "control-deck-media-controls",
		"options": {
			"type": "play/pause"
		}
	}
}

We've defined that button 0 will use the Control Deck Media Controls plugin to mimic pushing the play/pause button on your keyboard.

All that's left is to bootstrap the app in myapp.js

const ControlDeck = require('control-deck');
new ControlDeck('button-layout.json');

Now back in your console:

node myapp.js

If all went well, you'll have a single play / pause button in the top right of your Stream Deck.

Plugins

Control Deck is merely a framework for the plugins which do all the heavy lifting.

A listing of plugins is available in the wiki.

Building Your Own Plugins

A plugin is nothing more than a JS class. A very basic example that does nothing more than print "Hello World" to the console on instantiation:

class ControlDeckHelloWorld {
  constructor(streamDeck, buttonId, options) {
    console.log('Hello world!');
  }
}

Then use npm (or yarn) to package that up as control-deck-hello-world.

Three arguments will be passed to the constructor at instantiation.

streamDeck - an elgato-stream-deck instance representing your Stream Deck. Documentation for adding button listeners, drawing on the buttons, and more is in the elgato-stream-deck README.

buttonId - the button that we're concerned with here. Integer from 0-14.

options - the options specified in button-layout.json. Can take any shape that your plugin needs.
