## What it is
A webpack plugin that makes web projects offline-ready by generating a ServiceWorker (with AppCache fallback) that caches webpack output assets. It integrates via webpack.config and a small client-side runtime.

## Use cases
- make a webpack app work offline
- add a service worker to cache build assets
- build a progressive web app with app-shell caching
- cache webpack output for offline-first experience
- add appcache fallback for older browsers

## When to choose
- you have a webpack-based project and want offline support with minimal setup
- you need ServiceWorker caching with automatic asset precaching

## When to avoid
- you use Vite, Rollup, or a bundler other than webpack
- you need fine-grained runtime caching strategies (consider Workbox)
- you need actively maintained tooling - the project is in maintenance mode
