## What it is
sw-toolbox is a deprecated JavaScript library of helpers and caching strategies for service workers, enabling offline support for runtime requests like API calls and third-party resources. It has been superseded by Workbox and should not be used for new projects.

## Use cases
- cache API responses offline in a service worker
- add runtime caching strategies to a progressive web app
- make a web app work offline
- route dynamic requests to caching handlers in a service worker
- cache third-party resources at runtime

## When to choose
- maintaining a legacy codebase already built on sw-toolbox
- studying historical service worker caching patterns

## When to avoid
- starting any new progressive web app project
- you want maintained tooling - use Workbox instead
- you need precaching of static assets
- you need long-term support or bug fixes

## Facets
- artifact type: library
- maturity: abandoned
- function: caching, middleware, routing
- domain: web-development, frontend, developer-tools
- platform: browser
- tags: service-worker, offline-first, progressive-web-app, deprecated, pwa, runtime-caching, javascript, nodejs
