Progressive Web Apps

Progressive Web Apps (PWAs) are web applications that use modern browser APIs to deliver app-like experiences — including offline support, push notifications, and home screen installation — without requiring an app store. Built on service workers, web app manifests, and HTTPS, PWAs bridge the gap between websites and native applications while remaining fully discoverable by search engines.

Workbox (MIT) is Google’s set of libraries for adding offline support and caching strategies to service workers. It provides pre-caching, runtime caching, background sync, and navigation preloading with a declarative configuration API.

Vite Plugin PWA (MIT) adds zero-config PWA capabilities to Vite-based projects, generating service workers and web app manifests automatically. It supports both generateSW and injectManifest strategies from Workbox under the hood.

Serwist (MIT) is a modern service worker toolkit that evolved from the next-pwa project. It offers framework-agnostic service worker APIs along with dedicated integrations for Next.js, Svelte, and other frameworks.
