aiohttp is an asynchronous networking framework for Python that provides both an HTTP client and an HTTP server. It utilizes the asyncio library to handle network requests and server-side routing through a non-blocking event loop.
The framework includes a dedicated toolkit for establishing persistent bidirectional communication channels, enabling the implementation of both WebSocket servers and clients for real-time data exchange.
It covers a broad range of asynchronous network programming capabilities, including the development of web servers with customizable routing and the ability to send non-blocking requests to external web services.
