workerpool is a small JavaScript library that implements the thread pool pattern, letting you offload CPU-heavy tasks to a pool of workers on Node.js and in the browser. It provides a promise-based proxy API with task queuing, cancellation, timeouts, and crashed-worker handling.

Use cases

• offload cpu-intensive computations to web workers
• run heavy tasks without blocking the node.js event loop
• manage a pool of worker_threads or child processes
• cancel or timeout long-running background tasks
• parallelize data processing in the browser without freezing the ui

When to choose

• you need CPU-bound work offloaded from the main thread in Node.js or the browser
• you want one isomorphic API covering web workers, worker_threads, and child processes
• you need task queuing, cancellation, timeouts, and crash recovery in a tiny (~9 kB) dependency

When to avoid

• your workload is I/O-bound rather than CPU-bound
• you need GPU or native multithreading with shared memory
• you need a general-purpose job scheduler across machines rather than in-process workers
