From ea9ab5e352552acb3b3ff566c82be210ff056b15 Mon Sep 17 00:00:00 2001 From: pqhuy1987 Date: Tue, 21 Apr 2026 20:56:37 +0700 Subject: [PATCH] [CLAUDE] App+Infra+Api+FE: SignalR realtime notifications E2E MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Clean-arch split: - Application: IRealtimeNotifier (PushToUserAsync, abstraction) - Api: NotificationHub (/hubs/notifications, [Authorize]) + SignalRNotifier impl với IHubContext, 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.
