## 🏗️ Architecture Validation
|
|
|
|
### Hexagonal Architecture Compliance ✅
|
|
|
|
- ✅ **Domain isolation**: Zero external dependencies in domain layer
|
|
- ✅ **Dependency direction**: All dependencies point inward toward domain
|
|
- ✅ **Framework-free testing**: Tests run without NestJS
|
|
- ✅ **Database agnostic**: No TypeORM in domain
|
|
- ✅ **Pure TypeScript**: No decorators in domain layer
|
|
- ✅ **Port/Adapter pattern**: Clear separation of concerns
|
|
- ✅ **Compilation independence**: Domain compiles standalone
|
|
|
|
### Build Verification ✅
|
|
|
|
```bash
|
|
cd apps/backend && npm run build
|
|
# ✅ Compilation successful - 0 errors
|
|
```
|
|
|
|
### Test Verification ✅
|
|
|
|
```bash
|
|
cd apps/backend && npm test -- --testPathPattern="domain"
|
|
# Test Suites: 3 passed, 3 total
|
|
# Tests: 49 passed, 49 total
|
|
# ✅ All tests passing
|
|
```
