Schemas

Collection of schemas, and TypeScript declarations, to support the creation and validation of Stream Deck SDK files.

npm install @elgato/schemas

Stream Deck

Plugin

Manifest

Manifest JSON file responsible for defining a Stream Deck plugin.

// TypeScript type.
import { type Manifest } from "@elgato/schemas/streamdeck/plugins";

// Schema as an object.
import manifest from "@elgato/schemas/streamdeck/plugins/json";

// Schema as an object, with experimental import attributes
import manifest from "@elgato/schemas/streamdeck/plugins/manifest.json" with { type: "json" };

https://schemas.elgato.com/streamdeck/plugins/manifest.json

Layout

Layout JSON file that defines the layout of an action on Stream Deck +.

// TypeScript type.
import { type Layout } from "@elgato/schemas/streamdeck/plugins";

// Schema as an object.
import layout from "@elgato/schemas/streamdeck/plugins/json";

// Schema as an object, with experimental import attributes
import layout from "@elgato/schemas/streamdeck/plugins/layout.json" with { type: "json" };

https://schemas.elgato.com/streamdeck/plugins/layout.json

Usage

Schemas can be referenced directly within JSON files, providing intellisense and validation, using the $schema property, for example:

{
    "$schema": "https://schemas.elgato.com/streamdeck/plugins/manifest.json",
    "Name": "Wave Link",
    "Version": "1.9.0.0",
    "Author": "Elgato"
    // ...
}

Keywords

Custom keywords used within the provided schemas can also be directly imported to assist with constructing a validator, such as Ajv. Please note, the custom keyword definitions will only register the keyword, and will not provide validation.

import { keywordDefinitions } from "@elgato/schemas";
import Ajv from "ajv";

// add the "filePath" keyword (excluding validation)
ajv.addKeyword(keywordDefinitions.filePath);
