Greenworks is an open-source Node.js addon for integrating HTML5, NW.js, and Electron games with Steamworks. It exposes selected Steamworks APIs to JavaScript, supporting features such as achievements, cloud storage, user data, and other Steam platform services. The project was originally developed by Greenheart Games and is also maintained through community development.
