Starlette is a minimal ASGI framework for Python, similar to Flask but async-first. Used for fast APIs, real-time applications, and WebSocket services. FastAPI is built on Starlette. Salary: $110-170k USD. Time to proficiency: 4-5 weeks. Related to fastapi, python-async, and microservices-architecture.

Starlette ASGI என்றால் என்ன

Starlette is a lightweight ASGI (Asynchronous Server Gateway Interface) framework for Python, designed for building high-performance web applications. Unlike Flask (synchronous), Starlette is async-first: it uses Python's asyncio to handle thousands of concurrent connections efficiently. It provides routing, middleware, request/response handling, and WebSocket support. Starlette is the foundation for FastAPI (which adds validation and auto-docs). Teams use it for real-time APIs, microservices, and high-concurrency backends where resource efficiency matters. Starlette represents the modern Python web stack. It's lightweight (no batteries included) and performant (async-native). For teams that need high concurrency without the overhead of traditional frameworks, Starlette is ideal. It's also the foundation for FastAPI, which is one of the fastest-growing frameworks. Learning Starlette teaches async patterns in Python, a skill that transfers to other domains. Salaries are competitive ($140-200k USD senior) and growing as async adoption accelerates.

❓ FAQ

How does Starlette differ from Flask?

Flask is sync (threading-based); Starlette is async (event-loop-based). Starlette handles thousands of connections with fewer resources. Flask is easier for simple apps; Starlette excels at high-concurrency.

Is FastAPI just Starlette with validation?

Essentially. FastAPI adds Pydantic for request/response validation, automatic OpenAPI docs, and type hints. Starlette is the HTTP foundation; FastAPI builds on it. For simple APIs, Starlette is lighter.

How do you handle WebSockets in Starlette?

Starlette has built-in WebSocket support. Define a route with `@app.websocket_route()`, accept the connection, and send/receive messages. Enables real-time applications: chat, notifications, live updates.

What's ASGI?

ASGI (Asynchronous Server Gateway Interface) is a standard for async Python web frameworks, like WSGI for sync. Starlette implements ASGI; you run it on an ASGI server (Uvicorn, Hypercorn).

How do you scale Starlette apps?

Run multiple Starlette instances (Uvicorn processes) behind a load balancer (Nginx, AWS ALB). Add caching (Redis), database connection pools, and monitoring. Starlette itself is lightweight; scaling is horizontal.
