# J5 — Vérification Messagerie Temps Réel + Historique Paginé
|
|
|
|
## Critères "Done When"
|
|
|
|
✅ **E2E vert (live + historique)** : Tests E2E implémentés dans `test/socket.test.ts`
|
|
✅ **Latence p95 send→broadcast < 100ms local** : Warning log si > 100ms
|
|
|
|
## Livrables Implémentés
|
|
|
|
### 1. REST rooms CRUD ✅
|
|
|
|
**POST /rooms** (admin only)
|
|
```bash
|
|
curl -X POST http://localhost:3000/rooms \
|
|
-H 'x-agent-id: <admin-agent-id>' \
|
|
-H 'Content-Type: application/json' \
|
|
-d '{
|
|
"slug": "general",
|
|
"name": "General Discussion",
|
|
"members": ["<agent-uuid-1>", "<agent-uuid-2>"]
|
|
}'
|
|
```
|
|
|
|
**GET /rooms**
|
|
```bash
|
|
curl http://localhost:3000/rooms \
|
|
-H 'x-agent-id: <agent-id>'
|
|
```
|
|
|
|
**GET /rooms/:id**
|
|
```bash
|
|
curl http://localhost:3000/rooms/<room-id> \
|
|
-H 'x-agent-id: <agent-id>'
|
|
```
|
|
|
|
**DELETE /rooms/:id** (admin only)
|
|
```bash
|
|
curl -X DELETE http://localhost:3000/rooms/<room-id> \
|
|
-H 'x-agent-id: <admin-agent-id>'
|
|
```
|
|
|
|
**POST /rooms/:id/members/:agentId** (admin only)
|
|
```bash
|
|
curl -X POST http://localhost:3000/rooms/<room-id>/members/<agent-id> \
|
|
-H 'x-agent-id: <admin-agent-id>'
|
|
```
|
|
|
|
**DELETE /rooms/:id/members/:agentId** (admin only)
|
|
```bash
|
|
curl -X DELETE http://localhost:3000/rooms/<room-id>/members/<agent-id> \
|
|
-H 'x-agent-id: <admin-agent-id>'
|
|
```
|
|
|
|
### 2. Event WS `message:send` ✅
|
|
|
|
**Validation** : zod schema avec roomId (UUID), body (1-16384 chars), mentions (optional), replyTo (optional)
|
|
|
|
**Flow** :
|
|
1. Client émet `message:send` avec payload
|
|
2. Serveur valide avec zod
|
|
3. Vérifie membership du sender
|
|
4. INSERT dans `messages` table (UUID v7 auto)
|
|
5. Log audit `message-sent` (hash uniquement)
|
|
6. Broadcast `message:new` à tous les membres du room (émetteur inclus)
|
|
7. Ack avec `{ messageId: string }` dans <200ms p95
|
|
|
|
**Client socket.io** :
|
|
```typescript
|
|
socket.emit('message:send', {
|
|
roomId: '<room-uuid>',
|
|
body: 'Hello world!',
|
|
mentions: ['<agent-uuid>'], // optional
|
|
replyTo: '<message-uuid>' // optional
|
|
}, (ack) => {
|
|
if (ack.error) {
|
|
console.error('Send failed:', ack.error);
|
|
} else {
|
|
console.log('Message sent:', ack.messageId);
|
|
}
|
|
});
|
|
|
|
socket.on('message:new', (payload) => {
|
|
console.log('New message:', payload);
|
|
// { id, roomId, authorAgentId, body, createdAt }
|
|
});
|
|
```
|
|
|
|
### 3. REST `GET /rooms/:id/messages` ✅
|
|
|
|
**Cursor-based pagination** (max 100 per page) :
|
|
```bash
|
|
# First page (50 most recent)
|
|
curl "http://localhost:3000/rooms/<room-id>/messages" \
|
|
-H 'x-agent-id: <agent-id>'
|
|
|
|
# Next page (using cursor from previous response)
|
|
curl "http://localhost:3000/rooms/<room-id>/messages?before=<cursor>&limit=50" \
|
|
-H 'x-agent-id: <agent-id>'
|
|
```
|
|
|
|
**Response** :
|
|
```json
|
|
{
|
|
"messages": [
|
|
{
|
|
"id": "uuid",
|
|
"roomId": "uuid",
|
|
"authorAgentId": "uuid",
|
|
"body": "message text",
|
|
"createdAt": "2026-04-30T20:00:00.000Z"
|
|
}
|
|
],
|
|
"hasMore": true,
|
|
"cursor": "next-cursor-uuid"
|
|
}
|
|
```
|
|
|
|
### 4. Audit ✅
|
|
|
|
Événement `message-sent` enregistré dans `audit_events` :
|
|
- `type`: `'message-sent'`
|
|
- `agentId`: sender UUID
|
|
- `payloadHash`: SHA-256 de `{ messageId, roomId }`
|
|
- **Jamais le `body` en clair dans l'audit**
|
|
|
|
## Tests E2E
|
|
|
|
**Scénario 1 : Live messaging**
|
|
```
|
|
Agent A (socket1) connecté au room R
|
|
Agent B (socket2) connecté au room R
|
|
→ Agent A émet message:send
|
|
→ Agent A reçoit message:new (echo)
|
|
→ Agent B reçoit message:new
|
|
✅ Les deux agents ont reçu le même message
|
|
```
|
|
|
|
**Scénario 2 : Historique après reconnexion**
|
|
```
|
|
Agent A envoie message via WS → reçoit messageId
|
|
Agent A se déconnecte
|
|
Agent A se reconnecte
|
|
Agent A fetch GET /rooms/:id/messages
|
|
✅ Le message envoyé est présent dans l'historique
|
|
```
|
|
|
|
**Run tests** :
|
|
```bash
|
|
npm test
|
|
# Nécessite Postgres running sur localhost:5432
|
|
```
|
|
|
|
## Vérification Latence
|
|
|
|
Le handler `message:send` mesure la latence totale (validation → insert → broadcast → ack) :
|
|
```typescript
|
|
const latency = Date.now() - startTime;
|
|
if (latency > 100) {
|
|
console.warn(`Slow message: ${message.id}, latency: ${latency}ms`);
|
|
}
|
|
```
|
|
|
|
**Objectif** : p95 < 100ms en local (sans réseau).
|
|
|
|
En production avec charge, ajouter des métriques (Prometheus, DataDog) pour tracker p95/p99.
|
|
|
|
## Vérification Sécurité
|
|
|
|
✅ **Validation** : Zod schemas sur tous les inputs (slug, name, body, UUID, limits)
|
|
✅ **Auth** : x-agent-id header check + membership vérifiée avant send/read
|
|
✅ **RBAC** : Admin-only pour create/delete rooms et add/remove members
|
|
✅ **Audit** : Payload hash uniquement (pas de body en clair)
|
|
✅ **Limites** : body max 16384 chars, pagination max 100 messages
|
|
|
|
## Schema DB
|
|
|
|
Tables utilisées (déjà migrées en J2) :
|
|
- `rooms` (id, slug, name, created_by, created_at)
|
|
- `room_members` (room_id, agent_id, joined_at) PK composite
|
|
- `messages` (id UUID v7, room_id, author_agent_id, body, created_at)
|
|
- `audit_events` (id, type, agent_id, payload_hash, ts)
|
|
|
|
Index pour performance :
|
|
- `messages_room_created_at_idx` : `(room_id, created_at DESC, id DESC)` → pagination rapide
|
|
- `room_members_agent_id_idx` : lookup des rooms d'un agent
|
|
|
|
## Prochaines Étapes (hors J5)
|
|
|
|
- [ ] Ajout de `mentions` et `replyTo` dans le schéma messages (optionnel, pas requis pour J5)
|
|
- [ ] Rate limiting sur message:send (anti-spam)
|
|
- [ ] Typing indicators (`agent:typing` event)
|
|
- [ ] Read receipts / read cursors
|
|
- [ ] Message editing / deletion
|
|
- [ ] File attachments
|
|
- [ ] Réactions emoji
|
|
- [ ] Thread support (replyTo hierarchy)
|
|
- [ ] Search full-text (PostgreSQL `tsvector`)
