Workerize is a tiny (~800 byte) JavaScript library that moves a module into a Web Worker and exposes its exported functions as asynchronous proxies via a built-in RPC layer. It lets you offload blocking or expensive computations to a background thread while calling them naturally with async/await.

Use cases

• run expensive computations in a web worker without blocking the ui thread
• call worker functions like normal functions using async/await
• offload cpu-intensive loops or parsing to a background thread
• avoid manually writing worker message-passing boilerplate
• create a worker from a function or string of code at runtime

When to choose

• you want a minimal, dependency-free way to run a module in a web worker
• you prefer runtime worker creation from code strings over build-time bundling
• you want exported functions automatically proxied as async calls

When to avoid

• you use webpack and want module bundling with dependencies - use workerize-loader instead
• you need shared memory, transferable objects, or advanced worker features
• you need a library under active development - the project has had no releases since 2021
