Building Scalable APIs with FastAPI and MongoDB

Why FastAPI?

FastAPI has emerged as one of the fastest-growing Python web frameworks. Its combination of speed, developer experience, and automatic documentation makes it ideal for building modern APIs.

Setting Up Your Project

Start with a clean project structure:

app/
├── api/
├── models/
├── schemas/
└── core/

Database Integration

MongoDB combined with Motor's async capabilities provides a robust foundation for your data layer. Use connection pooling for optimal performance under load.

Best Practices

• Use Pydantic for data validation
• Implement proper error handling
• Add authentication middleware
• Write comprehensive tests
