## 🏗️ Architecture Compliance
### Hexagonal Architecture Validation
✅ **Domain Layer Independence:**
- Zero external dependencies (no NestJS, TypeORM, Redis in domain/)
- Pure TypeScript business logic
- Framework-agnostic entities and services
- Can be tested without any framework
✅ **Dependency Direction:**
- Application layer depends on Domain
- Infrastructure layer depends on Domain
- Domain depends on nothing
- All arrows point inward
✅ **Port/Adapter Pattern:**
- Clear separation of API ports (in) and SPI ports (out)
- Adapters implement port interfaces
- Easy to swap implementations (e.g., TypeORM → Prisma)
✅ **SOLID Principles:**
- Single Responsibility: Each class has one reason to change
- Open/Closed: Extensible via ports without modification
- Liskov Substitution: Implementations are substitutable
- Interface Segregation: Small, focused port interfaces
- Dependency Inversion: Depend on abstractions (ports), not concretions

---
## Relationships
```
organizations 1──* users
carriers 1──* rate_quotes
```
---
## Data Volumes
**Estimated Sizes**:
- `organizations`: ~1,000 rows
- `users`: ~10,000 rows
- `carriers`: ~50 rows
- `ports`: ~10,000 rows (seeded from UN/LOCODE)
- `rate_quotes`: ~1M rows/year (auto-deleted after expiry)
- `containers`: ~100K rows/year
---
## Migrations Strategy
**Migration Order**:
1. Create extensions (uuid-ossp, pg_trgm)
2. Create organizations table + indexes
3. Create users table + indexes + FK
4. Create carriers table + indexes
5. Create ports table + indexes (with GIN indexes)
6. Create rate_quotes table + indexes + FK
7. Create containers table + indexes + FK (Phase 2)
---
## Seed Data
**Required Seeds**:
1. **Carriers** (5 major carriers)
- Maersk (MAEU)
- MSC (MSCU)
- CMA CGM (CMDU)
- Hapag-Lloyd (HLCU)
- ONE (ONEY)
2. **Ports** (~10,000 from UN/LOCODE dataset)
- Major ports: Rotterdam (NLRTM), Shanghai (CNSHA), Singapore (SGSIN), etc.
3. **Test Organizations** (3 test orgs)
- Test Freight Forwarder
- Test Carrier
- Test Shipper
---
## Performance Optimizations
1. **Indexes**:
- Composite index on rate_quotes (origin, destination, container_type, etd) for search
- GIN indexes on ports (name, city) for fuzzy search with pg_trgm
- Indexes on all foreign keys
- Indexes on frequently filtered columns (is_active, type, etc.)
2. **Partitioning** (Future):
- Partition rate_quotes by created_at (monthly partitions)
- Auto-drop old partitions (>3 months)
3. **Materialized Views** (Future):
- Popular trade lanes (top 100)
- Carrier performance metrics
4. **Cleanup Jobs**:
- Delete expired rate_quotes (valid_until < NOW()) - Daily cron
- Archive old bookings (>1 year) - Monthly
---
## Security Considerations
1. **Row-Level Security** (Phase 2)
- Users can only access their organization's data
- Admins can access all data
2. **Sensitive Data**:
- password_hash: bcrypt with 12+ rounds
- totp_secret: encrypted at rest
- api_config: encrypted credentials
3. **Audit Logging** (Phase 3)
- Track all sensitive operations (login, booking creation, etc.)

## ❌ Error Handling
### Error Response Format
All errors follow this structure:
```json
{
"statusCode": 400,
"message": "Error description or array of validation errors",
"error": "Bad Request"
}
```
### HTTP Status Codes
| Code | Description | When Used |
|------|-------------|-----------|
| `200` | OK | Successful GET request |
| `201` | Created | Successful POST (resource created) |
| `400` | Bad Request | Validation errors, malformed request |
| `401` | Unauthorized | Missing or invalid authentication |
| `403` | Forbidden | Insufficient permissions |
| `404` | Not Found | Resource doesn't exist |
| `429` | Too Many Requests | Rate limit exceeded |
| `500` | Internal Server Error | Unexpected server error |
| `503` | Service Unavailable | Carrier API down, circuit breaker open |
### Validation Errors
```json
{
"statusCode": 400,
"message": [
"Origin must be a valid 5-character UN/LOCODE (e.g., NLRTM)",
"Container type must be one of: 20DRY, 20HC, 40DRY, 40HC, 40REEFER, 45HC",
"Quantity must be at least 1"
],
"error": "Bad Request"
}
```
### Rate Limit Error
```json
{
"statusCode": 429,
"message": "Too many requests. Please try again in 60 seconds.",
"error": "Too Many Requests",
"retryAfter": 60
}
```
### Circuit Breaker Error
When a carrier API is unavailable (circuit breaker open):
```json
{
"statusCode": 503,
"message": "Maersk API is temporarily unavailable. Please try again later.",
"error": "Service Unavailable",
"retryAfter": 30
}
```
---
## ⚡ Rate Limiting
**Status:** To be implemented in Phase 2
**Planned Limits:**
- 100 requests per minute per API key
- 1000 requests per hour per API key
- Rate search: 20 requests per minute (resource-intensive)
**Headers:**
```
X-RateLimit-Limit: 100
X-RateLimit-Remaining: 95
X-RateLimit-Reset: 1612345678
```
---
## 🔔 Webhooks
**Status:** To be implemented in Phase 3
Planned webhook events:
- `booking.confirmed` - Booking confirmed by carrier
- `booking.in_transit` - Shipment departed
- `booking.delivered` - Shipment delivered
- `booking.delayed` - Shipment delayed
- `booking.cancelled` - Booking cancelled
**Webhook Payload Example:**
```json
{
"event": "booking.confirmed",
"timestamp": "2025-02-15T10:30:00Z",
"data": {
"bookingId": "550e8400-e29b-41d4-a716-446655440001",
"bookingNumber": "WCM-2025-ABC123",
"status": "confirmed",
"confirmedAt": "2025-02-15T10:30:00Z"
}
}
```
---
## 📊 Best Practices
### Pagination
Always use pagination for list endpoints to avoid performance issues:
```
GET /api/v1/bookings?page=1&pageSize=20
```
### Date Formats
All dates use ISO 8601 format:
- Request: `"2025-02-15"` (date only)
- Response: `"2025-02-15T10:00:00Z"` (with timezone)
### Port Codes
Use UN/LOCODE (5-character codes):
- Rotterdam: `NLRTM`
- Shanghai: `CNSHA`
- Los Angeles: `USLAX`
- Hamburg: `DEHAM`
Find port codes: https://unece.org/trade/cefact/unlocode-code-list-country-and-territory
### Error Handling
Always check `statusCode` and handle errors gracefully:
```javascript
try {
const response = await fetch('/api/v1/rates/search', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify(searchParams)
});
if (!response.ok) {
const error = await response.json();
console.error('API Error:', error.message);
return;
}
const data = await response.json();
// Process data
} catch (error) {
console.error('Network Error:', error);
}
```

# Integration Tests
This directory contains integration tests for the Xpeditis backend infrastructure layer.
## Overview
Integration tests verify that our infrastructure adapters (repositories, cache, carrier connectors) work correctly with their respective external services or mocks.
## Test Coverage
### Redis Cache Adapter (`redis-cache.adapter.spec.ts`)
- ✅ Get and set operations with various data types
- ✅ TTL (Time To Live) functionality
- ✅ Delete operations (single, multiple, clear all)
- ✅ Statistics tracking (hits, misses, hit rate)
- ✅ Error handling and resilience
- ✅ Complex data structures (nested objects, arrays)
- ✅ Key patterns and namespacing
### Booking Repository (`booking.repository.spec.ts`)
- ✅ Save new bookings
- ✅ Update existing bookings
- ✅ Find by ID, booking number, organization, status
- ✅ Delete bookings
- ✅ Complex scenarios with nested data (shipper, consignee)
- ✅ Data integrity verification
### Maersk Connector (`maersk.connector.spec.ts`)
- ✅ Search rates with successful responses
- ✅ Request/response mapping
- ✅ Surcharge handling
- ✅ Vessel and service information
- ✅ Empty results handling
- ✅ Error scenarios (timeout, API errors, malformed data)
- ✅ Circuit breaker behavior
- ✅ Health check functionality
## Running Integration Tests
### Prerequisites
**For Redis tests:**
- Redis server running on `localhost:6379` (or set `REDIS_HOST` and `REDIS_PORT`)
- Tests use Redis DB 1 by default (not DB 0)
**For Repository tests:**
- PostgreSQL server running on `localhost:5432` (or set `TEST_DB_*` variables)
- Tests will create a temporary database: `xpeditis_test`
- Tests use `synchronize: true` and `dropSchema: true` for clean slate
### Commands
```bash
# Run all integration tests
npm run test:integration
# Run with coverage report
npm run test:integration:cov
# Run in watch mode (for development)
npm run test:integration:watch
# Run specific test file
npm run test:integration -- redis-cache.adapter.spec.ts
```
### Environment Variables
Create a `.env.test` file or set these variables:
```bash
# Database (for repository tests)
TEST_DB_HOST=localhost
TEST_DB_PORT=5432
TEST_DB_USER=postgres
TEST_DB_PASSWORD=postgres
TEST_DB_NAME=xpeditis_test
# Redis (for cache tests)
REDIS_HOST=localhost
REDIS_PORT=6379
REDIS_DB=1
# Carrier APIs (for connector tests - mocked in tests)
MAERSK_API_BASE_URL=https://api.maersk.com
MAERSK_API_KEY=test-api-key
```
## Test Strategy
### Redis Cache Tests
- Uses `ioredis-mock` for isolated testing
- No real Redis connection required for CI/CD
- Fast execution, no external dependencies
### Repository Tests
- **Option 1 (Current)**: Real PostgreSQL database with `synchronize: true`
- **Option 2 (Recommended for CI)**: Use `testcontainers` for ephemeral PostgreSQL
- Tests create and destroy schema between runs
- Each test cleans up its data in `afterEach` hooks
### Carrier Connector Tests
- Uses mocked HTTP calls (jest mocks on axios)
- No real API calls to carriers
- Simulates various response scenarios
- Tests circuit breaker and retry logic
## Coverage Goals
Target coverage for infrastructure layer:
- **Redis Cache Adapter**: 90%+
- **Repositories**: 80%+
- **Carrier Connectors**: 80%+
## Best Practices
1. **Isolation**: Each test should be independent and not rely on other tests
2. **Cleanup**: Always clean up test data in `afterEach` or `afterAll`
3. **Mocking**: Use mocks for external services where appropriate
4. **Assertions**: Be specific with assertions - test both happy paths and error cases
5. **Performance**: Keep tests fast (< 5 seconds per test suite)
## Troubleshooting
### "Cannot connect to Redis"
- Ensure Redis is running: `redis-cli ping` should return `PONG`
- Check `REDIS_HOST` and `REDIS_PORT` environment variables
- For CI: ensure `ioredis-mock` is properly installed
### "Database connection failed"
- Ensure PostgreSQL is running
- Verify credentials in environment variables
- Check that user has permission to create databases
### "Tests timeout"
- Check `testTimeout` in `jest-integration.json` (default: 30s)
- Ensure database/Redis are responsive
- Look for hanging promises (missing `await`)
## Future Improvements
- [ ] Add testcontainers for PostgreSQL (better CI/CD)
- [ ] Add integration tests for User and Organization repositories
- [ ] Add integration tests for additional carrier connectors (MSC, CMA CGM)
- [ ] Add performance benchmarks
- [ ] Add integration tests for S3 storage adapter
- [ ] Add integration tests for email service
