PWA: installable webclient, offline shell, web push
...
Installability:
- public/manifest.webmanifest (standalone, theme #16161E) + PNG icons
generated from logo.svg (regular + maskable, served via /images mount)
- index.html: manifest link, theme-color, apple-touch-icon
Offline shell:
- hand-rolled sw.js (no workbox): navigation = network-first (3s race)
with cached-shell fallback + background refresh (a stale cached shell
would 404 on entry chunks after a deploy); /assets/* cache-first
(content-hashed); /images/* cache-first capped; /api,/ws,/auth,/push,
/content pass-through
- vite closeBundle plugin stamps __NAVI_BUILD_VERSION__ (digest of
index.html + asset names) into dist/sw.js; sw.js served no-store so
every deploy reactivates the SW and activation evicts old caches
- SW registration in main.js, PROD only (dev HMR untouched)
- OfflineBanner (useOnline composable) over the app shell
Web push (VAPID, pywebpush):
- navi/push/ package: push_subscriptions table (postgres, boot-time DDL),
PushSubscriptionStore, PushService (async fan-out, to_thread sends,
404/410 prunes dead endpoints, per-session cooldown)
- routes: GET /push/vapid-key, POST/DELETE /push/subscribe (auth-gated)
- trigger in orchestrator run_agent + run_recall: push on StreamEnd when
no WebSocket client watches the session; fire-and-forget, never
disturbs the run; anonymous fallback only when auth is off
- client: usePush composable + Notifications settings panel (enable/
disable via PushManager.subscribe with the server VAPID key)
- notification click focuses the app at /#<session_id> (hash routing
opens the right chat); payload body is a markdown-stripped <=140-char
preview
NAVIVAPID keys empty = push fully disabled (graceful, like other optional
integrations). dist/ artifacts committed per repo convention.
Tests: pytest push store/service/routes/trigger (+23), vitest usePush
(83 webclient tests green). Full suite 1143 passed.
