refactor: split monolith into 3 microservices (frontend, backend, discord-gateway)

- Extract services into services/{frontend,backend,discord-gateway}
- Create packages/shared/ for shared logger, errors, utils, types
- Setup Modular MVC pattern in backend (controller→service→repository)
- Setup event-driven architecture in discord-gateway with Redis pub/sub
- Move Docker files to infra/docker/ with per-service Dockerfiles
- Update docker-compose.yml to use Traefik-only routing (no port exposes)
- Update GitHub Actions deploy workflow for multi-service matrix build
- Fix all import paths and resolve type errors across all services
- All 3 services pass tsc --noEmit clean

## Layer Separation
### 1. Controller Layer
**File:** `modules/*/[module].controller.ts`
**Responsibility:** HTTP request handling only
- Parse request (query, params, body)
- Validate using Zod schemas
- Call service methods
- Return HTTP response (200, 400, 404, 500)
- **No database calls**
- **No business logic**
**Example:**
```typescript
export function handleListMessages(req: Request, res: Response, next: NextFunction) {
return asyncHandler(async (req: Request, res: Response) => {
const query = messageQuerySchema.parse(req.query);
const result = await messagesService.listMessages(query);
res.json(result);
})(req, res, next);
}
```
### 2. Service Layer
**File:** `modules/*/[module].service.ts`
**Responsibility:** Business logic and orchestration
- Validate input (throw ValidationError if invalid)
- Orchestrate repository calls
- Apply business rules
- Handle cross-cutting concerns (auth, permissions)
- **No database calls directly**
- **No HTTP request/response handling**
**Example:**
```typescript
async listMessages(query: MessageQuery) {
if (!query.channelId && !query.guildId) {
throw new ValidationError("Either channelId or guildId is required");
}
return messagesRepository.findMany(query);
}
```
### 3. Repository Layer
**File:** `modules/*/[module].repository.ts`
**Responsibility:** All database operations
- Execute Drizzle ORM queries
- Handle database errors
- Return raw data (no transformation)
- **No business logic**
- **No HTTP handling**
**Example:**
```typescript
async findMany(query: MessageQuery) {
const db = getDatabase();
return db.select().from(messagesTable).where(...).limit(query.limit);
}
```
### 4. Schema Layer
**File:** `modules/*/[module].schema.ts`
**Responsibility:** Zod validation schemas
- Define request/response types
- Validate at controller entry point
- Export TypeScript types
**Example:**
```typescript
export const messageQuerySchema = z.object({
channelId: z.string().optional(),
limit: z.coerce.number().int().positive().default(50),
});
```
## Module Responsibilities
| Module | Purpose | Routes |
|--------|---------|--------|
| **messages** | Text message storage & retrieval | GET /api/messages, GET /api/messages/:channelId |
| **analytics** | Moderation statistics & trends | GET /api/analytics/overview, /daily-trend, /hourly-stats |
| **media** | Media file management | GET /api/media/list, POST /api/media/upload |
| **voice** | Voice recording management | GET /api/voice/recordings, POST /api/voice/connect |
| **health** | Service health checks | GET /api/health |
## Data Flow
### Request Flow (HTTP)
```
Client Request
Express Router (routes/index.ts)
Controller (parse request, validate schema)
Service (business logic, validation)
Repository (database query)
Database (PostgreSQL)
Repository (return data)
Service (transform/orchestrate)
Controller (format response)
Client Response
```
### Event Flow (WebSocket - Future)
```
Discord Gateway (publishes event)
Redis pub/sub
Backend WebSocket Server (ws/server.ts)
Broadcast to connected clients
Frontend (receives real-time update)
```
## Dependency Rules
### ✅ Allowed
- Controller → Service
- Service → Repository
- Service → Config
- Service → Logger
- Repository → Database
- Any layer → Errors, Logger, Config
### ❌ Forbidden
- Repository → Service (data flows up, not down)
- Repository → Controller
- Service → HTTP (no req/res in service)
- Controller → Database (must go through service)
- Cross-module repository imports (each module owns its data)
## Error Handling
All errors inherit from `AppError` with `code` and `statusCode`:
```typescript
throw new ValidationError("Invalid input", { field: "error" }); // 400
throw new NotFoundError("Message not found"); // 404
throw new UnauthorizedError("Invalid password"); // 401
throw new ForbiddenError("Access denied"); // 403
throw new AppError("Custom error", "CUSTOM_CODE", 500); // 500
```
## Configuration
All config via environment variables (`.env`), validated with Zod in `shared/config/index.ts`:
```env
# Server
WEBSERVER_PORT=3001
NODE_ENV=development
LOG_LEVEL=info
# Database
DATABASE_URL=postgresql://user:pass@localhost:5432/discord_moderation
# OR
DATABASE_HOST=localhost
DATABASE_PORT=5432
DATABASE_NAME=discord_moderation
DATABASE_USER=postgres
DATABASE_PASSWORD=secret
# Redis (optional, for pub/sub)
REDIS_URL=redis://localhost:6379
# Discord
MONITOR_GUILD_ID=123456789
# Admin
ADMIN_PASSWORD=secret123
```
## Testing Strategy
Each module should have tests:
- `messages.repository.test.ts` — Database query tests
- `messages.service.test.ts` — Business logic tests
- `messages.controller.test.ts` — HTTP handler tests
Use Vitest with mocked database and services.
## Next Steps
1. **Migrate Drizzle schema** from `src/database/schema.ts` to `services/backend/src/shared/database/schema.ts`
2. **Implement repository queries** for each module using Drizzle ORM
3. **Add WebSocket server** in `src/ws/server.ts` with Redis pub/sub listener
4. **Create Discord Gateway service** in `services/discord-gateway/` (separate microservice)
5. **Add Docker & CI/CD** for multi-service deployment
6. **Write integration tests** for full request flow
## Circular Dependency Check
✅ No circular dependencies detected:
- Modules are independent (each owns its data)
- Layers flow upward only (Repository → Service → Controller)
- Shared infrastructure has no dependencies on modules
- Cross-module communication via events (Redis pub/sub), not direct imports
