Use when adding or reviewing Progressive Web App capabilities such as installability, manifest metadata, Service Worker registration, Workbox caching, offline fallback, app update prompts, maskable icons, or iOS PWA compatibility. Do not use for general API caching or non-installable performance tuning; Chinese triggers include PWA, offline, Service Worker.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# PWA implementation ## Purpose Make web applications installable, offline and controllable to update. ## Procedure 1. Confirm whether PWA is worth doing: priority is given to mobile/desktop installations, weak network offline, and repeated access scenarios; do not force PWA when it is purely internal backend, has strong real-time streaming media, or only requires ordinary caching. 2. First complete the manifest, icon, theme color and HTML reference; the icon covers at least 192/512, Android needs to be maskable, and iOS needs apple touch icon. 3. Register the Service Worker and design an update prompt; do not forcefully refresh the user page after silently `skipWaiting()`. 4. Use Workbox or framework plug-in to manage precache/runtime cache; sensitive requests such as login, payment, and permission changes must go through the network. 5. Provide offline fallback page and installation prompt UI, and verify initial loading, offline access, update activation, uninstallation and reinstallation. ## Detailed reference …

How to install
mdr add bovinphang/frontend-craft/fec-pwa-implementation@sha256:ed859061ba305121The line at the top of this page pins the label git:20260611.9d7f5e4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
