### **Data Flow**
|
||||||
|
|
||||||
|
**Creating Inquiry:**
|
||||||
|
```
|
||||||
|
POST /inquiries (CreateInquiryDto)
|
||||||
|
→ InquiriesController.createInquiry()
|
||||||
|
→ CommandBus.execute(CreateInquiryCommand)
|
||||||
|
→ CreateInquiryHandler.execute()
|
||||||
|
- Validate listing exists (Prisma)
|
||||||
|
- Create InquiryEntity
|
||||||
|
- Save to repository (Prisma)
|
||||||
|
- Publish InquiryCreatedEvent via EventBus
|
||||||
|
→ Return { id, listingId, createdAt }
|
||||||
|
```
|
||||||
|
|
||||||
|
**Marking as Read:**
|
||||||
|
```
|
||||||
|
PATCH /inquiries/:id/read (agent only)
|
||||||
|
→ InquiriesController.markAsRead()
|
||||||
|
→ CommandBus.execute(MarkInquiryReadCommand)
|
||||||
|
→ MarkInquiryReadHandler.execute()
|
||||||
|
- Find inquiry entity
|
||||||
|
- Verify agent is listing owner
|
||||||
|
- Call entity.markAsRead()
|
||||||
|
- Update in repository
|
||||||
|
- Publish InquiryReadEvent via EventBus
|
||||||
|
→ Return { success: true }
|
||||||
|
```
|
||||||
|
|
||||||
|
**Getting Inquiries:**
|
||||||
|
```
|
||||||
|
GET /inquiries/listing/:id or /agent/me (with pagination)
|
||||||
|
→ InquiriesController.getByListing() or getMyInquiries()
|
||||||
|
→ QueryBus.execute(GetInquiriesByListingQuery or GetInquiriesByAgentQuery)
|
||||||
|
→ Handler delegates to repository
|
||||||
|
→ Repository.findByListing() or findByAgent()
|
||||||
|
- Queries Prisma with joins
|
||||||
|
- Maps to InquiryReadDto
|
||||||
|
- Returns PaginatedResult
|
||||||
|
→ Return paginated data
|
||||||
|
```
|
||||||
|
|
||||||

## 🔑 KEY CLASSES & HANDLERS
|
||||||
|
|
||||||
|
### **Domain Entity: InquiryEntity**
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
export class InquiryEntity extends AggregateRoot<string> {
|
||||||
|
// Properties
|
||||||
|
private _listingId: string;
|
||||||
|
private _userId: string;
|
||||||
|
private _message: string;
|
||||||
|
private _phone: string | null;
|
||||||
|
private _isRead: boolean;
|
||||||
|
|
||||||
|
// Factory Method
|
||||||
|
static createNew(id, listingId, userId, message, phone): InquiryEntity
|
||||||
|
→ Creates new inquiry with isRead=false
|
||||||
|
→ Emits InquiryCreatedEvent
|
||||||
|
|
||||||
|
// Business Logic
|
||||||
|
markAsRead(): void
|
||||||
|
→ Sets isRead to true
|
||||||
|
→ Emits InquiryReadEvent
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### **Command Handlers**
|
||||||
|
|
||||||
|
#### CreateInquiryHandler
|
||||||
|
```typescript
|
||||||
|
class CreateInquiryHandler implements ICommandHandler<CreateInquiryCommand> {
|
||||||
|
async execute(command: CreateInquiryCommand): Promise<CreateInquiryResult> {
|
||||||
|
// 1. Validate listing exists
|
||||||
|
const listing = await prisma.listing.findUnique(...)
|
||||||
|
if (!listing) throw NotFoundException
|
||||||
|
|
||||||
|
// 2. Create entity with factory
|
||||||
|
const inquiry = InquiryEntity.createNew(...)
|
||||||
|
|
||||||
|
// 3. Persist to database
|
||||||
|
await inquiryRepo.save(inquiry)
|
||||||
|
|
||||||
|
// 4. Publish domain events
|
||||||
|
const events = inquiry.clearDomainEvents()
|
||||||
|
events.forEach(e => eventBus.publish(e))
|
||||||
|
|
||||||
|
return { id, listingId, createdAt }
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
#### MarkInquiryReadHandler
|
||||||
|
```typescript
|
||||||
|
class MarkInquiryReadHandler implements ICommandHandler<MarkInquiryReadCommand> {
|
||||||
|
async execute(command: MarkInquiryReadCommand): Promise<void> {
|
||||||
|
// 1. Load aggregate root
|
||||||
|
const inquiry = await inquiryRepo.findById(...)
|
||||||
|
if (!inquiry) throw NotFoundException
|
||||||
|
|
||||||
|
// 2. Verify authorization
|
||||||
|
const listing = await prisma.listing.findUnique(...)
|
||||||
|
const agent = await prisma.agent.findUnique(...)
|
||||||
|
if (agent.id !== listing.agentId) throw ForbiddenException
|
||||||
|
|
||||||
|
// 3. Update domain state
|
||||||
|
inquiry.markAsRead()
|
||||||
|
|
||||||
|
// 4. Persist state
|
||||||
|
await inquiryRepo.markAsRead(...)
|
||||||
|
|
||||||
|
// 5. Publish events
|
||||||
|
const events = inquiry.clearDomainEvents()
|
||||||
|
events.forEach(e => eventBus.publish(e))
|
||||||
|
}
|
||||||
|
}
|
||||||

|
||||||
|
return this.inquiryRepo.findByListing(
|
||||||
|
query.listingId,
|
||||||
|
query.page,
|
||||||
|
query.limit
|
||||||
|
)
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
#### GetInquiriesByAgentHandler
|
||||||
|

|
||||||
|
class GetInquiriesByAgentHandler implements IQueryHandler<GetInquiriesByAgentQuery> {
|
||||||
|
async execute(query: GetInquiriesByAgentQuery): Promise<PaginatedResult<InquiryReadDto>> {

|
||||||
|
const agent = await prisma.agent.findUnique({ where: { userId } })
|
||||||
|
if (!agent) throw NotFoundException
|
||||||
|
|
||||||
|
// 2. Delegate to repository
|
||||||
|
return this.inquiryRepo.findByAgent(agent.id, page, limit)
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### **Repository Implementation**
|
||||||
|
|
||||||
|
#### PrismaInquiryRepository
|
||||||
|
|
||||||
|
**Methods:**
|
||||||
|
1. `findById(id)` - Single inquiry lookup
|
||||||
|
2. `save(entity)` - Create inquiry
|
||||||
|
3. `markAsRead(id)` - Update isRead flag
|
||||||
|
4. `findByListing(listingId, page, limit)` - Paginated search with joins
|
||||||
|
5. `findByAgent(agentId, page, limit)` - Paginated search via listing agent
|
||||||
|
6. `countUnreadByAgent(agentId)` - Unread count aggregation
|
||||||
|
|
||||||
|
**Prisma Relations Used:**
|
||||||
|
- `inquiry.listing` → property (for title)
|
||||||
|
- `inquiry.user` → fullName, phone
|
||||||
|
- `listing.agentId` → agent filter
|
||||||
|
- Pagination: skip/take with orderBy descending
|
||||||
|

## 🎓 ARCHITECTURAL INSIGHTS
|
||||||
|
|
||||||
|
### **Strengths**
|
||||||
|
|
||||||
|
1. **Clean Architecture** - Clear separation of concerns across layers
|
||||||
|
2. **CQRS Pattern** - Separate read/write paths enable scalability
|
||||||
|
3. **Domain-Driven Design** - Business logic in entities, not anemic models
|
||||||
|
4. **Event-Driven** - Domain events enable audit trails and event sourcing
|
||||||
|
5. **Testability** - Each layer independently testable with mocks
|
||||||
|
6. **Type Safety** - Full TypeScript with interfaces and strict types
|
||||||
|
7. **DI Framework** - NestJS provides dependency injection out of box
|
||||||
|
|
||||||
|
### **Design Decisions**
|
||||||
|
|
||||||
|
1. **InquiryEntity as Aggregate Root**
|
||||||
|
- Encapsulates inquiry business rules
|
||||||
|
- Controls state transitions via methods (createNew, markAsRead)
|
||||||
|
- Collects domain events
|
||||||
|
|
||||||
|
2. **Repository Pattern**
|
||||||
|
- Interface in domain, implementation in infrastructure
|
||||||
|
- Allows swapping data sources without affecting business logic
|
||||||
|
|
||||||
|
3. **Separate Read/Write DTOs**
|
||||||
|
- `CreateInquiryDto` (input) vs `InquiryReadDto` (output)
|
||||||
|
- Enables flexible API evolution
|
||||||
|
|
||||||
|
4. **CQRS Handlers**
|
||||||
|
- Commands handle mutations with authorization
|
||||||
|
- Queries handle reads with filtering
|
||||||
|
- Both independent, can be optimized separately
|
||||||
|
|
||||||
|
5. **Pagination Interface**
|
||||||
|
- Consistent pagination across all list endpoints
|
||||||
|
- Page + limit model with calculated totalPages
|
||||||

|
## 💡 Next Steps Recommended
|
||||||
|
|
||||||
|
### High Priority (Do These First)
|
||||||
|
1. Add tests for `McpIntegrationModule.onModuleInit()`
|
||||||
|
2. Test module dependency injection
|
||||||
|
3. Verify TypesenseClient initialization
|
||||||
|
|
||||||
|
### Medium Priority (Consider These)
|
||||||
|
1. Add integration tests for full SSE lifecycle
|
||||||
|
2. Test session timeout and cleanup
|
||||||
|
3. Add error recovery tests
|
||||||
|
|
||||||
|
### Low Priority (Future Enhancement)
|
||||||
|
1. Implement domain layer if more business logic is added
|
||||||
|
2. Add application handlers (CQRS) if needed
|
||||||
|
3. Implement infrastructure layer for persistence

|
||||||
|
imports: [SearchModule, AuthModule, McpCoreModule.forRoot({...})],
|
||||||
|
controllers: [McpTransportController],
|
||||||
|
})
|
||||||
|
|
||||||
|
Class: McpIntegrationModule implements OnModuleInit
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
Lifecycle Hook:
|
||||||
|
async onModuleInit(): Promise<void>
|
||||||
|
- Sets Typesense client on registry
|
||||||
|
- Re-initializes MCP servers
|
||||||
|

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
||||||
|
Type: NestJS HTTP Controller
|
||||||
|
Lines: 102
|
||||||
|
Purpose: HTTP transport layer for MCP Server-Sent Events (SSE) connections
|
||||||
|
|
||||||
|
Decorators Applied:
|
||||||
|
@ApiTags('mcp') - Swagger grouping
|
||||||
|
@ApiBearerAuth('JWT') - API doc
|
||||||
|
@Controller('mcp') - Route prefix
|
||||||
|
@UseGuards(JwtAuthGuard) - Auth guard (all endpoints)
|
||||||
|
|
||||||
|
Private Properties:
|
||||||
|
transports: Map<string, SSEServerTransport>
|
||||||
|
→ Active session tracking by sessionId
|
||||||
|
|
||||||
|
Constructor:
|
||||||
|
McpTransportController(registry: McpRegistryService)
|
||||||
|
|
||||||
|
Endpoints (3):
|
||||||
|
|
||||||
|
1️⃣ GET /mcp/servers
|
||||||
|
├── Decorator: @Get('servers')
|
||||||
|
├── Throttle: 30 requests per 60,000ms
|
||||||
|
├── Auth: JwtAuthGuard ✅
|
||||||
|
├── Returns: { servers: string[] }
|
||||||
|
├── HTTP Status: 200 OK, 401 Unauthorized
|
||||||
|
└── Logic: Returns server.names from registry
|
||||||
|
|
||||||
|
2️⃣ GET /mcp/:serverName/sse
|
||||||
|
├── Decorator: @Get(':serverName/sse')
|
||||||
|
├── Throttle: 5 requests per 60,000ms ⚡ (STRICTER)
|
||||||
|
├── Params: serverName (string)
|
||||||
|
├── Auth: JwtAuthGuard ✅, CurrentUser decorator
|
||||||
|
├── Returns: SSE stream (response.write)
|
||||||
|
├── HTTP Status: 200 (stream), 404 (not found), 401 (unauthorized)
|
||||||
|
└── Logic:
|
||||||
|
1. Verify server exists (throw NOT_FOUND if not)
|
||||||
|
2. Create SSEServerTransport instance
|
||||||
|
3. Store in Map[sessionId]
|
||||||
|
4. Attach close listener for cleanup
|
||||||
|
5. Connect transport to server
|
||||||
|
|
||||||
|
3️⃣ POST /mcp/:serverName/messages
|
||||||
|
├── Decorator: @Post(':serverName/messages')
|
||||||
|
├── Throttle: 30 requests per 60,000ms
|
||||||
|
├── Params: serverName (string)
|
||||||
|
├── Query: sessionId (required)
|
||||||
|
├── Auth: JwtAuthGuard ✅, CurrentUser decorator
|
||||||
|
├── Returns: Delegate response to transport
|
||||||
|
├── HTTP Status: 200 OK, 400 (missing sessionId), 404 (not found), 401 (unauthorized)
|
||||||
|
└── Logic:
|
||||||
|
1. Extract sessionId from query
|
||||||
|
2. Validate sessionId present (throw BAD_REQUEST if not)
|
||||||
|
3. Look up transport (throw NOT_FOUND if expired)
|
||||||
|
4. Delegate to transport.handlePostMessage()
|
||||||
|
|
||||||
|
Status: ✅ Well tested (see spec file)

Mocking Strategies Used:
|
||||||
|
1. vi.mock() - Module mocking (SSEServerTransport)
|
||||||
|
2. vi.fn() - Function mocks (service methods)
|
||||||
|
3. mockReturnValue() - Sync returns
|
||||||
|
4. mockResolvedValue() - Async returns
|
||||||
|
5. Manual mock objects - req/res simulation
|
||||||
|
6. Reflect.getMetadata() - Decorator inspection
|
||||||
|
|
||||||

SUMMARY
|
||||||
|
================================================================================
|
||||||
|
|
||||||
|
The MCP module is a SIMPLIFIED integration layer that:
|
||||||
|
✅ Exposes 3 HTTP endpoints for MCP server access
|
||||||
|
✅ Handles SSE connection lifecycle
|
||||||
|
✅ Provides rate limiting and JWT authentication
|
||||||
|
✅ Well-tested at controller level (174 lines of tests)
|
||||||
|
|
||||||
|
Areas for Improvement:
|
||||||
|
⚠️ Module initialization not tested
|
||||||
|
⚠️ No domain layer implementation
|
||||||
|
⚠️ No application handlers (CQRS)
|
||||||
|
⚠️ No infrastructure adapters
|
||||||
|
|
||||||
|
The module follows project conventions:
|
||||||
|
✅ Vitest for testing
|
||||||
|
✅ vi.fn() for mocking
|
||||||
|
✅ Decorator verification with Reflect API
|
||||||
|
✅ Organized __tests__/ subdirectory
|
||||||
|
|
||||||
|

## 5. TESTING PATTERNS FROM OTHER MODULES
|
||||||
|
|
||||||
|
### Pattern 1: Auth Module (Simple Handler)
|
||||||
|
```typescript
|
||||||
|
describe('LoginUserHandler', () => {
|
||||||
|
let handler: LoginUserHandler;
|
||||||
|
let mockTokenService = { generateTokenPair: vi.fn() };
|
||||||
|
|
||||||
|
beforeEach(() => {
|
||||||
|
handler = new LoginUserHandler(mockTokenService as any);
|
||||||
|
});
|
||||||
|
|
||||||
|
it('generates token pair', async () => {
|
||||||
|
mockTokenService.generateTokenPair.mockResolvedValue(tokenPair);
|
||||||
|
const result = await handler.execute(command);
|
||||||
|
expect(result).toEqual(tokenPair);
|
||||||
|
});
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
### Pattern 2: Payments Module (Complex Handler)
|
||||||
|
```typescript
|
||||||
|
describe('CreatePaymentHandler', () => {
|
||||||
|
let handler: CreatePaymentHandler;
|
||||||
|
let mockPaymentRepo: { [K in keyof IPaymentRepository]: ReturnType<typeof vi.fn> };
|
||||||
|
let mockGatewayFactory: { getGateway: ReturnType<typeof vi.fn> };
|
||||||
|
|
||||||
|
beforeEach(() => {
|
||||||
|
mockPaymentRepo = {
|
||||||
|
findById: vi.fn(),
|
||||||
|
save: vi.fn().mockResolvedValue(undefined),
|
||||||
|
};
|
||||||
|
handler = new CreatePaymentHandler(mockPaymentRepo as any, mockGatewayFactory as any);
|
||||||
|
});
|
||||||
|
|
||||||
|
it('creates payment successfully', async () => {
|
||||||
|
const result = await handler.execute(command);
|
||||||
|
expect(result.paymentId).toBeDefined();
|
||||||
|
expect(mockPaymentRepo.save).toHaveBeenCalledTimes(1);
|
||||||
|
});
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
### Pattern 3: Domain Entity Testing
|
||||||
|
```typescript
|
||||||
|
import { describe, it, expect } from 'vitest';
|
||||||
|
|
||||||
|
describe('PaymentEntity', () => {
|
||||||
|
it('should create payment with events', () => {
|
||||||
|
const payment = PaymentEntity.createNew(...);
|
||||||
|
expect(payment.status).toBe('PENDING');
|
||||||
|
expect(payment.domainEvents).toHaveLength(1);
|
||||||
|
expect(payment.domainEvents[0]).toBeInstanceOf(PaymentCreatedEvent);
|
||||||
|
});
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
### Pattern 4: Infrastructure Service Testing
|
||||||
|
```typescript
|
||||||
|
describe('ZalopayService', () => {
|
||||||
|
let service: ZalopayService;
|
||||||
|
|
||||||
|
beforeEach(() => {
|
||||||
|
const mockConfig = {
|
||||||
|
get: vi.fn((key) => env[key]),
|
||||||
|
getOrThrow: vi.fn((key) => env[key] || throw),
|
||||||
|
};
|
||||||
|
service = new ZalopayService(mockConfig as any);
|
||||||
|
});
|
||||||
|
|
||||||
|
it('should verify valid callback', () => {
|
||||||
|
const mac = crypto.createHmac('sha256', key2).update(dataStr).digest('hex');
|
||||||
|
const result = service.verifyCallback({ data: dataStr, mac });
|
||||||
|
expect(result.isValid).toBe(true);
|
||||||
|
});
|
||||||
|
});
|
||||||
|
```

## 🎯 Key Classes
|
||||||
|
|
||||||
|
### McpIntegrationModule
|
||||||
|
```typescript
|
||||||
|
class McpIntegrationModule implements OnModuleInit {
|
||||||
|
constructor(
|
||||||
|
typesenseClient: TypesenseClientService,
|
||||||
|
mcpRegistry: McpRegistryService,
|
||||||
|
logger: LoggerService,
|
||||||
|
) {}
|
||||||
|
|
||||||
|
async onModuleInit(): Promise<void> {
|
||||||
|
// Set typesense client, re-initialize servers, log results
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### McpTransportController
|
||||||
|
```typescript
|
||||||
|
@Controller('mcp')
|
||||||
|
@UseGuards(JwtAuthGuard)
|
||||||
|
class McpTransportController {
|
||||||
|
listServers(): { servers: string[] }
|
||||||
|
|
||||||
|
async handleSse(serverName, user, req, res): Promise<void>
|
||||||
|
|
||||||
|
async handleMessage(serverName, user, req, res): Promise<void>
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## 🔧 Testing Patterns
|
||||||
|
|
||||||
|
### Module Mocking
|
||||||
|
```typescript
|
||||||
|
vi.mock('@goodgo/mcp-servers', () => ({
|
||||||
|
SSEServerTransport: class MockSSE {
|
||||||
|
sessionId = 'mock-session-id';
|
||||||
|
handlePostMessage = vi.fn().mockResolvedValue(undefined);
|
||||||
|
},
|
||||||
|
}));
|
||||||
|
```
|
||||||
|
|
||||||
|
### Service Mocking
|
||||||
|
```typescript
|
||||||
|
mockRegistry = {
|
||||||
|
getServerNames: vi.fn(),
|
||||||
|
getServer: vi.fn(),
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
### Decorator Verification
|
||||||
|
```typescript
|
||||||
|
const guards = Reflect.getMetadata('__guards__', McpTransportController);
|
||||||
|
const throttleLimit = Reflect.getMetadata('THROTTLER:LIMITdefault', method);
|
||||||
|
```
|
||||||
|
|
||||||
|
## 📚 Testing Examples from Other Modules
|
||||||
|
|
||||||
|
### Auth Module Pattern (Simple)
|
||||||
|
- Minimal dependencies
|
||||||
|
- Direct handler instantiation
|
||||||
|
- Focus on behavior verification
|
||||||
|
|
||||||
|
### Payments Module Pattern (Complex)
|
||||||
|
- Multiple dependency mocks
|
||||||
|
- Business rule testing
|
||||||
|
- Event bus verification
|
||||||
|
|
||||||
|
### Domain Entity Pattern
|
||||||
|
- Explicit vitest imports
|
||||||
|
- State transition testing
|
||||||
|
- Domain event verification
|
||||||
|
- Error handling with Result types
|
||||||
|
|
||||||
|
### Infrastructure Pattern
|
||||||
|
- External service simulation
|
||||||
|
- Security testing (crypto)
|
||||||
|
- Complex test data builders
|
||||||
|
|
||||||
|
## 🚀 Running Tests
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Run all MCP tests
|
||||||
|
pnpm test -- src/modules/mcp
|
||||||
|
|
||||||
|
# Run with watch
|
||||||
|
pnpm test -- --watch src/modules/mcp
|
||||||
|
|
||||||
|
# Run with coverage
|
||||||
|
pnpm test -- --coverage src/modules/mcp
|
||||||
|
|
||||||
|
# Run specific test
|
||||||
|
pnpm test -- src/modules/mcp/presentation/__tests__/mcp-transport.controller.spec.ts
|
||||||
|
```
|
||||||
|
|
||||||
|
## 💡 Recommendations
|
||||||
|
|
||||||
|
### High Priority
|
||||||
|
- ✅ Controller is well tested - maintain this
|
||||||
|
- 📝 Add tests for McpIntegrationModule.onModuleInit()
|
||||||
|
- 📝 Test module dependency injection
|
||||||
|
|
||||||
|
### Lower Priority
|
||||||
|
- 🏗️ If domain logic added, follow payments patterns
|
||||||
|
- 🏗️ If handlers added, use CQRS patterns
|
||||||
|
- 🏗️ Add integration tests for SSE lifecycle
