Stream Deck TS-SDK

A library that helps you develop plugins for Elgato's Stream Deck.

Installation

  • Install via npm:
npm install --save streamdeck-typescript

Decorators

This Plugin adds a few decorators for classes and methods.

Available decorators

  • methods
    • @SDOnPiEvent(event) - Listens for specified event in the property inspector context and if triggered, calls method
      • Overhands EventData (*NameOfEvent*Event; Example: KeyDownEvent, KeyUpEvent, WillAppearEvent)
    • @SDOnActionEvent(event) - Listens for specified event in the action context and if triggered, calls method
      • Overhands EventData (*NameOfEvent*Event; Example: KeyDownEvent, KeyUpEvent, WillAppearEvent)

Usage

You can see an example in the example folder or look through the Source docs

Initializing Plugin

Elgato uses 2 different files. The Action file (which handels all actions), and the Property Inspector file (which is for settings)

counter.ts

import {StreamDeckPluginHandler} from '../src';
import {CounterAction}           from './actions/counter.action';

export class Counter extends StreamDeckPluginHandler {
    constructor() {
        super();
        new CounterAction(this, 'fun.shiro.counter.action');
    }
}

new Counter();

plugin.html

<!DOCTYPE html>
<html lang="en">
<head>
    <title>Test Plugin</title>
    <meta charset="utf-8">
    <script src="dist/bundle.js"></script>
</head>
<body>
</body>
</html>

Here you can see. After the build you have only one file (bundle.js in this case) and this gets loaded.

counter-pi.ts

import {DidReceiveSettingsEvent, SDOnPiEvent, StreamDeckPropertyInspectorHandler} from '../src';
import {SettingsInterface}                                                        from './interfaces/settings.interface';

class CounterPi extends StreamDeckPropertyInspectorHandler {
    private count: HTMLInputElement;
    private stepsCount: HTMLInputElement;

    constructor() {
        super();
    }

    @SDOnPiEvent('documentLoaded')
    onDocumentReady() {
        this.count = document.getElementById('count') as HTMLInputElement;
        this.count.addEventListener('keyup', () =>
            this.settingsManager.setContextSettingsAttributes(
                this.actionInfo.context, {count: this.count.valueAsNumber}, 500));
        this.stepsCount = document.getElementById('steps') as HTMLInputElement;
        this.stepsCount.addEventListener('keyup', () =>
            this.settingsManager.setContextSettingsAttributes(
                this.actionInfo.context, {steps: this.stepsCount.valueAsNumber}, 500));

        const settings = this.settingsManager.getContextSettings<SettingsInterface>(this.actionInfo.context);

        this.count.value = (settings?.count ?? 0).toString();
        this.stepsCount.value = (settings?.steps ?? 1).toString();
    }

    @SDOnPiEvent('didReceiveSettings')
    private onSettingsReceived({payload: {settings}}: DidReceiveSettingsEvent<SettingsInterface>) {
        if (Object.keys(settings).length <= 0)
            return;

        this.count.value = settings.count.toString() ?? 0;
        this.stepsCount.value = settings.steps.toString() ?? 1;
    }
}

new CounterPi();

counter.action.ts

import {
    DidReceiveSettingsEvent,
    KeyDownEvent,
    KeyUpEvent,
    SDOnActionEvent,
    StreamDeckAction,
    WillAppearEvent
}                          from '../../src';
import {Counter}           from '../counter';
import {SettingsInterface} from '../interfaces/settings.interface';

export class CounterAction extends StreamDeckAction<Counter, CounterAction> {
    private keyUpTimer: any;

    constructor(private plugin: Counter, private actionName: string) {
        super(plugin, actionName);
    }

    @SDOnActionEvent('willAppear')
    private onAppear({context, payload: {settings}}: WillAppearEvent<SettingsInterface>) {
        this.plugin.setTitle((settings.count ?? 0).toString(), context);
    }

    @SDOnActionEvent('keyUp')
    private onKeyUp({context, payload: {settings}}: KeyUpEvent<SettingsInterface>) {
        clearTimeout(this.keyUpTimer);
        const steps = settings.steps ?? 1;
        const count = (settings.count ?? 0) + steps;
        this.plugin.setTitle(count.toString(), context);
        this.plugin.setSettings<SettingsInterface>({steps, count}, context);
    }

    @SDOnActionEvent('keyDown')
    private onKeyDown({context, payload: {settings}}: KeyDownEvent<SettingsInterface>) {
        this.keyUpTimer = setTimeout(() => {
            const steps = settings.steps ?? 1;
            this.plugin.setSettings<SettingsInterface>(
                {
                    steps,
                    count: steps * -1
                }, context
            );
            this.plugin.setTitle('0', context);
        }, 2000);
    }

    @SDOnActionEvent('didReceiveSettings')
    private onSettings({context, payload: {settings}}: DidReceiveSettingsEvent<SettingsInterface>) {
        this.plugin.setTitle(settings.count.toString() ?? 0, context);
    }
}

settings.interface.ts

export interface SettingsInterface {
    count: number,
    steps: number
}

Building the Plugin

I would suggest you to do it like in the example with browserify, terser, tsify, typescript and for development watchify

See package.json and tsconfig.json

{
    "scripts": {
        "build": "tsc -p tsconfig.json",
        "build-example": "browserify -p tsify example/counter-pi.ts | terser -cm --comments false -o dist/bundle-pi.js && browserify -p tsify example/counter.ts | terser -cm --comments false -o dist/bundle.js",
        "watch": "start watchify --debug -p tsify example/counter.ts -o dist/bundle.js && start watchify --debug -p tsify example/counter-pi.ts -o dist/bundle-pi.js",
        "documentation": "typedoc src/index.ts",
        "test": "echo \"Error: no test specified\" && exit 1"
    }
}

How to contribute?

Just fork the repository and create PR's, but we use standard-version to optimal release the plugin.

standard-version is following the conventionalcommits specification which follows the angular commit guidelines
