A TypeScript library providing Rust-inspired concurrency primitives for JavaScript, including a managed worker pool, Mutexes, Semaphores, and shared memory via SharedArrayBuffer. It abstracts Web Workers and serialization so multithreaded code feels like standard async JavaScript across browser, Node.js, Deno, and Bun.

Use cases

• run cpu-bound tasks in parallel in javascript
• use web workers without boilerplate
• share state between threads safely in node
• create a thread pool in the browser
• pass data to workers with move semantics
• use mutexes and semaphores in javascript

When to choose

• you need true parallelism for CPU-heavy work in JS across browser and server runtimes
• you want safe shared-memory concurrency primitives instead of raw Worker messaging
• you want a managed worker pool sized to hardware concurrency

When to avoid

• your workload is I/O-bound and async/await is sufficient
• you need mature, battle-tested production threading with a large ecosystem
• you target environments without SharedArrayBuffer support
