一覽

Sanic is a Python async web framework optimized for speed. Supports async/await, handles thousands of concurrent connections, and minimal overhead vs. Flask/Django. Used for high-performance APIs, WebSocket servers, and microservices. Learnable in 4–6 weeks with Python fundamentals and async basics. Sits alongside FastAPI, ASGI frameworks, and async Python. Moderate salary impact but growing demand for async-capable Python developers. Overlaps with asyncio, WebSockets, and microservices architecture.

什麼是 Sanic Async Web

Sanic is a Python async web framework for building high-performance web applications and APIs. Unlike Flask (synchronous, handles one request per thread) or Django (heavyweight, batteries-included), Sanic is minimalist and async-native. Sanic uses ASGI (Asynchronous Server Gateway Interface) to handle thousands of concurrent connections with a single process, making it ideal for real-time applications (WebSockets), high-throughput APIs, and microservices. Sanic applications are written with async/await syntax, allowing non-blocking I/O (database queries, HTTP calls) without spawning threads. Middleware, request handlers, and response writing are all async.

❓ 常見問題

Is Sanic faster than FastAPI?
Similar performance. Both use ASGI (async). Sanic benchmarks faster on microbenchmarks; FastAPI has better ecosystem and docs. Use FastAPI for new projects.
Can I use Sanic with Django models?
Not directly, Django is sync-based. Use async-compatible ORMs (SQLAlchemy, Tortoise ORM) with Sanic. Or use FastAPI+Django integration.
Does Sanic support CORS and authentication?
Yes. CORS middleware built-in; implement JWT or OAuth via middleware or decorators.
How do I run Sanic in production?
Use Gunicorn + Uvicorn workers (e.g., `gunicorn --workers 4 --worker-class sanic.worker.GunicornWorker app:app`).
Is Sanic suitable for beginners?
Not really. Requires understanding async/await, ASGI, and event loops. Learn FastAPI or Flask first.
