Caching Strategies
- workbox-core:
workbox-core
is part of the Workbox suite, which provides a comprehensive set of tools for implementing advanced caching strategies. It supports precaching, runtime caching, and allows you to configure multiple caching strategies for different routes and resources. It is highly customizable and optimized for performance, making it suitable for complex applications. - workbox-window:
workbox-window
does not directly implement caching strategies, but it complements Workbox by providing a client-side API for managing service worker registration and updates. It works alongside Workbox libraries to enhance the overall caching and service worker experience. - sw-toolbox:
sw-toolbox
allows you to define caching strategies for different types of requests using a simple API. You can easily implement cache-first, network-first, stale-while-revalidate, and other strategies by specifying them in your service worker code. It offers more flexibility and control compared to the polyfill. - serviceworker-cache-polyfill:
serviceworker-cache-polyfill
provides basic support for the Cache API, allowing you to implement simple caching strategies like cache-first and network-first. However, it does not provide built-in support for advanced caching strategies or configuration options.
Browser Support
- workbox-core:
workbox-core
is part of the Workbox suite, which is designed for modern browsers with service worker support. It leverages the latest web technologies to provide advanced caching features, making it unsuitable for older browsers without service worker support. - workbox-window:
workbox-window
is also designed for modern browsers and works best in environments where service workers are supported. It does not provide backward compatibility for older browsers. - sw-toolbox:
sw-toolbox
is compatible with modern browsers that support service workers. It does not provide polyfills for older browsers, so it is best suited for projects targeting browsers with service worker support. - serviceworker-cache-polyfill:
serviceworker-cache-polyfill
is designed to provide caching functionality in browsers that do not fully support the Cache API. It is particularly useful for ensuring compatibility with older browsers while still allowing modern browsers to take advantage of the native Cache API.
Ease of Use
- workbox-core:
workbox-core
is part of a larger suite of tools, which may require some time to fully understand and utilize all its features. However, it is well-documented and provides powerful capabilities for developers who need more control over their caching strategies. - workbox-window:
workbox-window
is designed to be simple and intuitive, providing an easy way to interact with service workers from the client side. Its API is straightforward, making it easy for developers to integrate it into their applications. - sw-toolbox:
sw-toolbox
is user-friendly and provides a simple API for defining caching strategies. Its documentation is clear, and it allows developers to implement caching with minimal effort, making it a great choice for projects that need quick solutions. - serviceworker-cache-polyfill:
serviceworker-cache-polyfill
is easy to use, especially for developers who need a simple solution for adding caching functionality to their service workers. Its lightweight nature and straightforward API make it accessible for quick implementations.
Code Examples
- workbox-core:
Advanced caching with
workbox-core
import { precacheAndRoute } from 'workbox-precaching'; import { registerRoute } from 'workbox-routing'; import { CacheFirst, NetworkFirst } from 'workbox-strategies'; precacheAndRoute([ { url: '/index.html', revision: '123' }, { url: '/styles.css', revision: '123' }, { url: '/script.js', revision: '123' },]); registerRoute('/api/data', new CacheFirst({ cacheName: 'api-cache', plugins: [ new ExpirationPlugin({ maxAgeSeconds: 3600 }), ],})); registerRoute('/images/*', new NetworkFirst({ cacheName: 'image-cache',}));
- workbox-window:
Service worker registration with
workbox-window
import { Workbox } from 'workbox-window'; const wb = new Workbox('/sw.js'); wb.register().then(() => { console.log('Service Worker registered'); }); wb.addEventListener('waiting', () => { console.log('New version available'); wb.waiting.postMessage('SKIP_WAITING'); });
- sw-toolbox:
Caching with
sw-toolbox
import 'sw-toolbox'; self.addEventListener('install', (event) => { event.waitUntil( caches.open('my-cache').then((cache) => { return cache.addAll(['/index.html', '/styles.css', '/script.js']); }) ); }); swToolbox.router.get('/api/data', swToolbox.cacheFirst({ cache: { name: 'api-cache', maxAgeSeconds: 3600 }, })); swToolbox.router.get('/images/*', swToolbox.networkFirst({ cache: { name: 'image-cache' }, }));
- serviceworker-cache-polyfill:
Basic caching with
serviceworker-cache-polyfill
if ('serviceWorker' in navigator) { navigator.serviceWorker.register('/sw.js').then(() => { console.log('Service Worker registered'); }); } self.addEventListener('install', (event) => { event.waitUntil( caches.open('my-cache').then((cache) => { return cache.addAll(['/index.html', '/styles.css', '/script.js']); }) ); }); self.addEventListener('fetch', (event) => { event.respondWith( caches.match(event.request).then((response) => { return response || fetch(event.request); }) ); });
