## What it is
A Webpack loader that automatically moves a JavaScript module and its dependencies into a Web Worker, exposing exported functions as asynchronous RPC proxies. It bundles a tiny RPC implementation and works seamlessly with async/await syntax.

## Use cases
- run expensive computations off the main thread in a browser app
- move a module into a web worker without writing worker boilerplate
- call worker functions as if they were normal async functions
- offload CPU-intensive loops from the UI thread
- bundle worker code with webpack including its dependencies
- inline a web worker as a blob in a webpack build

## When to choose
- you use Webpack and want minimal-effort Web Worker integration
- you want exported module functions automatically proxied as async worker calls
- you need worker code bundled with its dependencies

## When to avoid
- you don't use Webpack as your bundler
- you need fine-grained control over worker messaging or transferable objects
- the project needs actively maintained tooling for modern bundlers like Vite

## Facets
- artifact type: library
- maturity: maintenance
- function: build-tool, rpc, concurrency
- domain: web-development, frontend, developer-tools
- platform: browser
- tags: webpack-loader, web-worker, javascript, async, nodejs, web-server
