## Blog REST API Implementation Plan

### Phase 1: Project Setup (15 min)
1. Initialize Node.js project with Express
2. Set up TypeScript configuration
3. Install dependencies (express, pg, jwt, joi)
4. Configure environment variables
5. Set up project structure

### Phase 2: Database Layer (30 min)
6. Design database schema
   - users table (id, email, password_hash, created_at)
   - posts table (id, user_id, title, content, published, created_at, updated_at)
   - comments table (id, post_id, user_id, content, created_at)
7. Create migration files
8. Set up database connection pool
9. Implement database models

### Phase 3: Authentication (45 min)
10. Implement user registration endpoint
11. Implement login endpoint with JWT
12. Create authentication middleware
13. Add password hashing with bcrypt
14. Implement token refresh logic

### Phase 4: Posts API (40 min)
15. GET /api/posts - List all published posts (with pagination)
16. GET /api/posts/:id - Get single post
17. POST /api/posts - Create new post (auth required)

### Phase 6: Validation & Error Handling (30 min)
24. Add request validation with Joi
25. Implement global error handler
26. Add input sanitization
27. Implement rate limiting

### Phase 7: Testing (60 min)
28. Write unit tests for models
29. Write integration tests for auth endpoints
30. Write integration tests for posts endpoints
31. Write integration tests for comments endpoints
32. Achieve 80%+ code coverage

### Phase 8: Documentation & Deployment (30 min)
33. Generate API documentation with Swagger
34. Create README with setup instructions
35. Add Docker configuration
36. Set up CI/CD pipeline
