An incremental cache for the web

sw-precache is a service worker precache generator used to create scripts that enable offline functionality for web applications. It acts as a build-time asset cache manager that hashes static files and manages their versioning within a service worker cache. The project provides a runtime cache configurator to define caching strategies and request handlers for dynamic content based on URL patterns. It also includes an offline fallback handler to intercept network failures and serve cached fallback pages. The toolset covers the generation of service worker code and manifests, content-hash bas

Service Worker Toolbox provides some simple helpers for use in creating your own service workers. Specifically, it provides common caching strategies for dynamic content, such as API calls, third-party resources, and large or infrequently used local resources that you don't want precached.

Workbox is a modular library and toolkit designed for managing service workers in progressive web applications. It provides a comprehensive framework for handling asset caching, request routing, and background script lifecycle management, enabling developers to build web applications that function reliably offline and load efficiently. The project distinguishes itself through a declarative routing engine and a plugin-based architecture that allows for the injection of custom logic into the request and response processing pipeline. It supports advanced caching patterns, such as cache-first or
