Actor processes for JavaScript

A tiny, typed runtime for building concurrent systems out of long-lived processes — no callbacks, no event soup. Everything typed.

Why posipaki

• Processes, not callbacks. Every actor is a self-contained process with its own state and mailbox.
• Fork children. Spawn sub-actors that report back up, with lifecycle hooks and clean shutdown.
• Pause, resume, exit. Your actor lives and dies on its own terms.
• Distributed. Spawn children in a different process, different runtime or connect through websocket.
• One function. The whole API is defineActor.
