@darrellvs/node-steam-deck-sdk

An unofficial SDK for Elgato's Stream Deck / Stream Deck + devices

IMPORTANT

This package relies on the WebSocket Proxy plugin for Stream Deck. Which you can find here.
Special thanks to Yann Bizeul for his excellent work on this plugin!
This package is not affiliated with Elgato or Yann Bizeul.

Introduction

This package provides you with utilities to interact with Elgato's Stream Deck devices.
It allows you to listen for changes on the device and send commands to the device.

Installation

Install @darrellvs/node-steam-deck-sdk with npm

  npm install @darrellvs/node-steam-deck-sdk

or yarn

  yarn add @darrellvs/node-steam-deck-sdk

or (if you dare) pnpm

  pnpm add @darrellvs/node-steam-deck-sdk

Features

• Bi-directional communication
  Listen for changes and send commands to the Stream Deck plugin.

• Multiple device types supported
  This SDK supports both the Stream Deck and Stream Deck + devices.

• Set displayed data
  Set the displayed data on the buttons and dials / lcds.
  Allows you to change the image, text, and other properties of the buttons and dials / lcds.

• TypeScript support
  This package is written in TypeScript and provides type definitions.

• Easy to use
  The SDK is designed to be easy to use and understand.

• Provided examples
  Examples are provided to help you get started.

All communication is bi-directional, and thus allows you to listen for changes:

// Log when and how much the dial with id dial_1 is rotated
streamDeck.onDialRotate('dial_1', (ticks) => {
  console.log(`Dial 1 rotated ${ticks} ticks`);
});

// Or more advanced, log when the LCD for dial 1 is held, and log the position of the tap
streamDeck.onLcdHold('dial_1', ({ tapPosition }) => {
  console.log(
    `LCD of dial 1 held at position x:${tapPosition.x} y:${tapPosition.y}`
  );
});

More extensive examples available here!

Available events

The following events are available, with their respective parameters:

onDialRotate(dial_id, (ticks, params) => void): void

// The amount of ticks the dial was rotated
ticks: number;
params: {
  // The physical coordinates of the dial on the device
  coordinates: {
    column: number;
    row: number;
  }
  // The IP address + port of the server that sent the event
  remoteServer: string;
}

Example usage

streamDeck.onDialRotate('dial_id', (ticks, { coordinates, remoteServer }) => {
  console.log(`Dial rotated ${ticks} ticks`);
  console.log(
    `Dial is located at column ${coordinates.column} and row ${coordinates.row}`
  );
  console.log(`Event was sent by ${remoteServer}`);
});

onDialPress(dial_id, (params) => void): void

params: {
  // The physical coordinates of the dial on the device

    y: number;
  }
}

Example usage

streamDeck.onLcdTap('dial_id', ({ coordinates, remoteServer, tapPosition }) => {

  console.log(
    `Dial / LCD is located at column ${coordinates.column} and row ${coordinates.row}`
  );
  console.log(`Event was sent by ${remoteServer}`);
  console.log(`Tap was at x:${tapPosition.x} y:${tapPosition.y}`);
});

onLcdHold(dial_id, (params) => void): void

params: {
  // The physical coordinates of the dial on the device
  coordinates: {
    column: number;
    row: number;
  }
  // The IP address + port of the server that sent the event

    );
    console.log(`Event was sent by ${remoteServer}`);
    console.log(`Button is ${!isInMultiAction && 'not'} in a multi-action`);
  }
);

Additionally, you may listen to events emitted by the Stream Deck plugin:

pluginConnected

This event is emitted when the Stream Deck plugin connects to the WebSocket server.

Example usage

streamDeck.on('pluginConnected', () => {
  console.log(`Stream Deck plugin connected`);
});

willAppear

This event is emitted when a button or dial / lcd is about to appear on the Stream Deck.
Use this if you need to process some data, set an initial state (value, indicator, layout, image, etc.) before the plugin appears.

Example usage

streamDeck.on('willAppear', (id, params) => {
  console.log(`Element with id ${id} will appear`);
  console.log(`Parameters:`, params);
});

willDisappear

This event is emitted when a button or dial / lcd is about to disappear from the Stream Deck.
Use this if you need to clean up, reset, or save some data before the plugin disappears.

Example usage

streamDeck.on('willDisappear', (id, params) => {
  console.log(`Element with id ${id} will disappear`);
  console.log(`Parameters:`, params);
});

Notes

I will not be actively updating this library

As long as Elgato doesn't break anything.
Minor issues may be patched, major issues may or may not 👀
