Solopreneur's Secret Weapon|Developing Microservices Web App with Cursor|From Modular 2 MicroService

We dive into the Layers of Microservices Architecture
Layer | Responsibility
API (endpoints) | Handle HTTP, routing
Schemas | Data validation
Services | Business logic
Models | Data structure

Review 30 to 35 Python libraries (equivalent libraries in other languages will be present)
1. API Layer (Router/Controller)
FastAPI → fastapi (for defining routes and handling requests)
Pydantic → pydantic (for request/response validation)
2. Service Layer (Business Logic)
No specific package needed → This layer contains business rules and logic.
3. Data Access Layer (Repository)
SQLAlchemy → sqlalchemy (ORM for database interaction)
Alembic → alembic (for database migrations)
4. Database Layer
PostgreSQL Driver → asyncpg (for PostgreSQL)
MySQL Driver → aiomysql (for MySQL)
SQLite → sqlite3 (built-in)
5. Authentication & Security
JWT → python-jose, pyjwt (for token-based authentication)
Password Hashing → passlib (for bcrypt password hashing)
6. Configuration Management
Dotenv → python-dotenv (for .env configuration loading)
7. Dependency Injection (DI)
FastAPI Depends → fastapi.Depends (for injecting dependencies)
8. Inter-Service Communication
HTTP Requests → httpx (for async HTTP calls)
Message Queue → pika (for RabbitMQ), celery (for task queues)
gRPC → grpcio (for gRPC communication)
