We present next-pwa-pack, a package designed to integrate PWA support into Next.js applications quickly and without complications.
Motivation and problem solved: many projects require PWA support, but implementing service workers, cache management, and synchronization between tabs consumes time and produces unexpected errors. We tried existing solutions and they were heavy or didn't fit well with App Router. With next-pwa-pack we sought a simple, reliable, and ready-to-use solution.
What next-pwa-pack includes: automatic service worker registration, automatic copying of project files such as sw.js, manifest.json, and offline.html, utilities to control the cache from the client and server, synchronization between tabs, and a development panel for debugging in dev mode.
How it works in broad strokes: the package installs a service worker that caches HTML pages with TTL, stores static assets for repeat visits, and displays offline.html when there is no connection or cache available. It also exposes messages to update, disable, or clear the cache and to activate new versions of the service worker.
Integration with server and App Router: a server action called revalidatePWA is included that can be invoked from server actions, API routes, or server components. Additionally, there is an HOC called withPWA to wrap middleware or SSR logic and enable server-side revalidation and SSE event emission to clients.
Developer experience: when installing the package, the files sw.js, offline.html, and manifest.json are copied to public. If files with those names already exist, they are not overwritten. Server actions are also generated in app actions to facilitate revalidations from the backend.
Quick setup: simply wrap the application with PWAProvider and the rest connects automatically. Provider options allow changing the service worker path, enabling devMode to see a status panel, and configuring SSE revalidation listening.
PWAProvider provider functions: automatic service worker registration, navigation interception to cache the current page in SPA, storage event listening to synchronize cache between tabs, SSE listening for server-initiated revalidations, and a DevPWAStatus panel with controls to clear cache, reload the worker, and force updates.
Service worker behavior: HTML caching with a default TTL of ten minutes that can be adjusted in sw.js, permanent caching of static assets such as CSS, JS, and images, message handling for CACHE_CURRENT_HTML, REVALIDATE_URL, DISABLE_CACHE, ENABLE_CACHE, SKIP_WAITING, and CLEAR_STATIC_CACHE, and offline mode that attempts to restore content when the connection returns.
Common usage examples: updating cache after creating content on the client by calling updateSWCache with the affected routes, revalidating from the server by invoking revalidatePWA with the list of URLs, or clearing the cache on logout with clearAllCache and redirecting to login.
Included client API: clearAllCache, reloadServiceWorker, updatePageCache, unregisterServiceWorkerAndClearCache, updateSWCache, disablePWACache, enablePWACache, clearStaticCache, and usePWAStatus to access state in components.
Support for external revalidation: an API route can be exposed that receives secrets, tags, and URLs to force cache clearing or updating after changes from a CMS or external systems.
Debugging tips: check the service worker registration in browser tools, inspect Cache Storage for html-cache-v2, test Offline from DevTools with devMode enabled, and review logs that indicate SW registration and cached entries.
Limitations and recommendations: run over HTTPS in production, cache only GET to avoid risks, keep sensitive data out of the cache, and adjust exclusions using variables like CACHE_EXCLUDE. The default TTL is in sw.js and will soon be configurable from a configuration file.
