## What it is
A Webpack plugin from Google Chrome Labs that automatically bundles and compiles Web Worker modules referenced via `new Worker('./file.js', { type: 'module' })`. It makes module workers work in all browsers supporting Web Workers, down to IE 10.

## Use cases
- bundle web workers with webpack
- use module workers in older browsers
- compile worker files loaded via new Worker()
- offload computation to background threads in a webpack app
- avoid manual worker entry-point configuration

## When to choose
- you're on Webpack 4 and need worker bundling
- you want module workers to work in browsers without native module worker support
- you want zero-config worker bundling with a simple constructor syntax

## When to avoid
- you're using Webpack 5, which has built-in worker support via new Worker(new URL(...))
- your workers use dynamic, Blob, or data URLs
- the project needs active maintenance - last release was 2021
