description AIOHTTP Overview

AIOHTTP is a Python 3 framework designed for building asynchronous HTTP servers and clients. It leverages the asyncio library to achieve efficient handling of concurrent requests, making it suitable for creating high-performance APIs and backend applications. Developers working on network services or those needing rapid response times will find AIOHTTP particularly useful.

help AIOHTTP FAQ

Is aiohttp only a web server framework or also an HTTP client?

aiohttp is both an asynchronous HTTP client library and a server-side web framework for Python. It sits on top of asyncio, so one event loop can handle many network connections without blocking on each request.

When would someone choose aiohttp instead of FastAPI?

aiohttp is a lower-level asyncio framework with built-in client and server primitives, while FastAPI is centered on typed API development and OpenAPI generation. Developers often pick aiohttp when they want direct control over async sessions, WebSockets, and request handling.

Does aiohttp support WebSockets?

Yes, aiohttp includes WebSocket support on the server side and in its client tools. That makes it practical for chat services, streaming dashboards, and real-time control panels written in Python.

What is a common aiohttp mistake with ClientSession?

A common mistake is creating a new ClientSession for every request. aiohttp's own usage pattern encourages reusing a session so connection pooling can work across many HTTP calls.
