[CLAUDE] App+Infra+Api+FE: SignalR realtime notifications E2E
Deploy SOLUTION_ERP / build-deploy (push) Successful in 2m43s
Clean-arch split:
- Application: IRealtimeNotifier (PushToUserAsync, abstraction)
- Api: NotificationHub (/hubs/notifications, [Authorize]) +
SignalRNotifier impl với IHubContext<NotificationHub>, uses
Clients.User(userId) (default provider resolves NameIdentifier="sub")
- Infrastructure: NotificationPushInterceptor — SaveChangesInterceptor
capture Notification entities state=Added trong SavingChanges,
push qua IRealtimeNotifier trong SavedChanges sau khi commit thành
công. Zero caller changes — handlers chỉ cần db.Add(Notification).
Attached vào ApplicationDbContext cùng với AuditingInterceptor.
Auth:
- JWT config thêm OnMessageReceived event: read ?access_token= từ
query string khi path = /hubs/* (WebSockets không set headers).
- SignalRNotifier singleton (stateless, chỉ delegate IHubContext).
FE (both apps):
- @microsoft/signalr 8.0.7 vào package.json.
- lib/realtime.ts: singleton connection với lazy start + automatic
reconnect [0,2s,5s,10s,15s] + accessTokenFactory lấy từ localStorage.
- NotificationBell: useEffect subscribe 'notification-created' khi
isAuthenticated. On push: invalidate query + toast.message. Fallback
polling giảm từ 30s → 60s (realtime cover gap).
- AuthContext.logout: dynamic import stopConnection() — avoid leaking
auth'd socket across users.
Result: ERP-grade feel. Contract transition → Drafter nhận toast ngay
trong vòng 100-300ms (same-origin WebSocket), không cần F5 hay polling.
