| 31 | ## Review Areas |
| 32 | |
| 33 | ### 1. System Design |
| 34 | |
| 35 | **Structure** |
| 36 | - Is the system appropriately decomposed? |
| 37 | - Are component boundaries clear and logical? |
| 38 | - Is coupling minimized and cohesion maximized? |
| 39 | - Are dependencies managed properly? |
| 40 | |
| 41 | **Scalability** |
| 42 | - Can the system handle increased load? |
| 43 | - Are there single points of failure? |
| 44 | - Is horizontal scaling possible? |
| 45 | - Are stateless components used where appropriate? |
| 46 | |
| 47 | **Performance** |
| 48 | - Are there potential bottlenecks? |
| 49 | - Is caching used effectively? |
| 50 | - Are expensive operations optimized? |
| 51 | - Is database access efficient? |
| 52 | |
| 53 | ### 2. Code Organization |
| 54 | |
| 55 | **Project Structure** |
| 56 | ``` |
| 57 | project/ |
| 58 | ├── src/ |
| 59 | │ ├── core/ # Business logic, domain models |

| 66 | └── config/ |
| 67 | ``` |
| 68 | |
| 69 | **Module Design** |
| 70 | - Clear module boundaries |
| 71 | - Single responsibility per module |
| 72 | - Minimal public interfaces |
| 73 | - Internal implementation hiding |

| 75 | |
| 76 | ### 3. API Design |
| 77 | |
| 78 | **RESTful APIs** |
| 79 | ``` |
| 80 | GET /api/v1/users # List users |
| 81 | GET /api/v1/users/:id # Get user |
| 82 | POST /api/v1/users # Create user |
| 83 | PUT /api/v1/users/:id # Update user |
| 84 | DELETE /api/v1/users/:id # Delete user |
| 85 | |
| 86 | # Use proper HTTP status codes: |
| 87 | # 200 OK, 201 Created, 204 No Content |
| 88 | # 400 Bad Request, 401 Unauthorized, 403 Forbidden, 404 Not Found |
| 89 | # 500 Internal Server Error, 503 Service Unavailable |
| 90 | ``` |
| 91 | |
| 92 | **API Versioning** |
| 93 | - URL versioning (/api/v1/) |
| 94 | - Header versioning (Accept: application/vnd.api.v1+json) |
| 95 | - Backward compatibility considerations |
| 96 | - Deprecation strategy |
| 97 | |
| 98 | **API Documentation** |
| 99 | - OpenAPI/Swagger specification |
| 100 | - Request/response examples |
| 101 | - Error codes and handling |
| 102 | - Rate limiting policies |
| 103 | |
| 104 | ### 4. Data Architecture |
| 105 | |
| 106 | **Data Modeling** |
| 107 | - Appropriate database choice (SQL vs NoSQL) |
| 108 | - Schema normalization level |
| 109 | - Relationship definitions |
| 110 | - Index strategy |
| 111 | |
| 112 | **Data Access Layer** |
| 113 | - Repository pattern implementation |
| 114 | - Query optimization |
| 115 | - Connection pooling |
| 116 | - Transaction management |
| 117 | - Caching strategy |
| 118 | |
| 119 | **Data Flow** |
| 120 | ``` |
| 121 | Client → API → Service Layer → Repository → Database |
| 122 | ↓ |
| 123 | Validation, Authorization |
| 124 | ↓ |

| 156 | ```typescript |
| 157 | interface ApiError { |
| 158 | code: string; // Machine-readable error code |
| 159 | message: string; // Human-readable message |
| 160 | details?: unknown; // Additional context |
| 161 | timestamp: string; // ISO 8601 timestamp |
| 162 | requestId: string; // Trace request |
| 163 | } |
| 164 | ``` |

| 180 | email: user.email, |
| 181 | requestId: req.id, |
| 182 | duration: Date.now() - startTime |
| 183 | }); |
| 184 | ``` |
| 185 | |

| 204 | ↓ |
| 205 | Integration Tests (20%) → Component interaction |
| 206 | ↓ |
| 207 | Unit Tests (70%) → Individual functions |
| 208 | ``` |
| 209 | |
