## What it is
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
