hlang is an open-source flow-based programming language for TypeScript and JavaScript. A program is a graph of Readable, Transform, and Writable nodes. Nodes exchange data through named ports, and every port is an RxJS stream, so connections stay live while data flows.
A graph can be written in code, stored as JSON (IGraph), run in process by the interpreter, compiled ahead of time to an ES module, or built in a visual editor. The engine does not depend on any editor.
