The Pixel Dust Game Engine (PDG) is an open source, professional quality 2D game engine. It provides system independent abstractions of common elements needed by game developers.
This is the node.js plugin portion of it for game servers.
PDG is focused on making a broad array of capabilities available to developers regardless of the OS platform they are targeting. Currently it works on Mac OS X, Windows, and iOS. The server side Node.js plugin works on Linux and Mac OS X.
The PDG API is designed to make simple things easy to do, without adding undue complexity to more complicated problems.
The node plugin version is aimed at game servers, so it leaves out the graphics and sound systems. However, it still includes all the Sprite and Physics capabilities for server side simulation.
Man Pages are included, and more API documentation can be found at:
