Matterbridge accessory platform example plugin
August 11, 2026 · View on GitHub
Matterbridge accessory platform example plugin is a template to develop your own plugin using the accessory platform.
It exposes a cover device that continuously moves position and shows how to use the command handlers (you can control the device).
If you want to write your plugin, the easiest way to start create a new plugin is to clone the Matterbridge Plugin Template which has Dev Container support for instant development environment and all tools and extensions (like Node.js, npm, TypeScript, ESLint, Prettier, Jest and Vitest) already loaded and configured.
If you like this project and find it useful, please consider giving it a star on GitHub and sponsoring it.

Repository toolchain
Note: This repository uses a new toolchain. It replaces the traditional TypeScript / ESLint / Prettier / Jest stack with a faster and lighter setup.
- No
typescript 6.xpackage — replaced by TypeScript Native 7.x. - No ESLint, no Prettier — replaced by the oxc stack: oxlint for linting and oxfmt for formatting.
- No Jest — replaced by Vitest, which is much faster and natively supports ESM without extra configuration.
- Far fewer development dependencies — the number of installed packages drops from ~600 to ~75. A clean install is much faster.
- Much faster linting and formatting — oxlint and oxfmt run in a fraction of the time required by the ESLint / Prettier pipeline.
- Much faster builds — tsgo compiles the project in a fraction of the time required by the standard
tscbuild. - Editor support — use the VS Code extensions for tsgo and oxc to get the same experience in the editor.
