# Change: Fix Real-time Notifications Alignment
|
|
|
|
## Why
|
|
現行實作與 collaboration spec 的 Real-time Notifications requirement 有以下差距：
|
|
1. 通知僅寫入資料庫，未透過 WebSocket 即時推播
|
|
2. 未使用 Redis Pub/Sub 處理多 process 推播
|
|
3. 使用者連線時未補送未讀通知
|
|
|
|
## What Changes
|
|
- **WebSocket Manager** - 建立 WebSocket 連線管理模組
|
|
- **Redis Pub/Sub** - 整合 Redis 處理跨 process 通知推播
|
|
- **NotificationService** - 新增即時推播呼叫
|
|
- **API** - 新增 `/ws/notifications` WebSocket endpoint
|
|
- **Frontend** - 整合 WebSocket 接收即時通知
|
|
|
|
## Impact
|
|
- Affected specs: `collaboration`
|
|
- Affected code:
|
|
- `backend/app/core/websocket.py` - 新增 WebSocket 管理
|
|
- `backend/app/core/redis_pubsub.py` - 新增 Redis Pub/Sub 服務
|
|
- `backend/app/services/notification_service.py` - 加入即時推播
|
|
- `backend/app/api/notifications/router.py` - 新增 WebSocket endpoint
|
|
- `frontend/src/services/websocket.ts` - 新增 WebSocket client
|
|
- `frontend/src/contexts/NotificationContext.tsx` - 整合即時通知
|
|
|
|
## Implementation Phases
|
|
|
|
### Phase 1: WebSocket Infrastructure
|
|
- WebSocket 連線管理器
|
|
- 使用者連線/斷線處理
|
|
- 連線時補送未讀通知
|
|
|
|
### Phase 2: Redis Pub/Sub Integration
|
|
- Redis Pub/Sub 服務封裝
|
|
- 多 process 通知廣播
|
|
- 訊息序列化/反序列化
|
|
|
|
### Phase 3: Service Integration
|
|
- NotificationService 加入推播
|
|
- 前端 WebSocket client
|
|
- 未讀數量即時更新
|
|
|
|
## Dependencies
|
|
- collaboration (已完成)
|
|
- Redis 已在 user-auth 中使用
|
|
|
|
## Technical Decisions
|
|
- 使用 FastAPI WebSocket 原生支援
|
|
- Redis Pub/Sub 處理多 worker 同步
|
|
- 使用者以 user_id 為 channel key
