What problem does it solve?

Deterministic, drift-free timing engine for JavaScript/TypeScript. It provides logical-time scheduling with structured concurrency, enabling precise control over when waits resolve and avoiding wall-clock drift.

Core Features & Use Cases

  • Deterministic logical-time scheduling with TimeContext and a drift-free base time.
  • Structured concurrency via branch() and branchWait() with join semantics.
  • Dual execution modes: realtime (setTimeout/RAF) and offline (step-based) for reproducible testing.
  • Beat-aware tempo with TempoMap and BPM ramping support.
  • Deterministic RNG per context for reproducible randomness.
  • Barrier primitives and priority queue-based scheduling for scalable coordination.

Quick Start

Use the library to start a realtime root context and wait for 1 second of logical time. Then cancel if needed.
