HFSM Core

Hierarchical Finite State Machine – Embeddable Library

The @statewalker/fsm core library provides a simple and concise API to define processes as a series of transitions between individual states, with the ability to associate specific behaviors to state activations and deactivations.

• Getting Started – create your first state machine with the low-level FsmProcess engine.
• The startProcess Runner – attach per-state behaviour through one load callback; the way most consumers use the library.
• Serialization – dump a running machine to a plain object and restore it later.
• Tracing & Logging – watch the machine move without editing any handler.
• API Reference – the complete exported surface.
• GitHub: Source code – explore the library implementation.

Some features:

• Completely self-contained library
• No external runtime dependencies
• Minimal bundle size impact
• Written in TypeScript
• Works with any JavaScript environment – browser, Node.js and Deno compatible
