Question 1

How to set up WebSockets in Starlette?

Accepted Answer

Starlette has built-in WebSocket support. Define WebSocket routes in your application and handle connections asynchronously using the WebSocket class, similar to HTTP endpoints, with examples in the documentation.

Question 2

Starlette vs FastAPI: which one should I use?

Accepted Answer

Starlette is the underlying ASGI toolkit for FastAPI. Choose Starlette for minimal control and maximum performance; FastAPI adds automatic OpenAPI docs, data validation, and dependency injection on top, making it better for rapid API development.

Question 3

How to handle authentication in Starlette?

Accepted Answer

Starlette provides session and cookie middleware via optional dependencies, but for full authentication like OAuth, you need to implement custom logic or integrate libraries such as Authlib, as it lacks built-in auth systems.

Question 4

Can I use Starlette with Django?

Accepted Answer

Yes, through ASGI compatibility. You can mount Starlette applications within Django's ASGI setup or use it for specific async endpoints, but integration requires configuration and may not be seamless for all use cases.

Question 5

What's the best way to deploy a Starlette app?

Accepted Answer

Deploy using ASGI servers like Uvicorn, Daphne, or Hypercorn. For production, use process managers like Gunicorn with Uvicorn workers for better scalability and reliability, following deployment guides in the documentation.

Question 6

How to test Starlette applications effectively?

Accepted Answer

Starlette includes a test client built on httpx, allowing you to write unit tests for endpoints without running a live server. Use it with pytest or similar frameworks for comprehensive testing coverage.
