aiohttp is an asynchronous HTTP client and server framework for Python's asyncio library.
The tool addresses the need to handle HTTP communication without blocking, allowing concurrent requests and responses through async/await syntax. It provides both client-side capabilities for making HTTP requests and server-side functionality for building web applications. The framework includes built-in support for WebSockets, middleware, and pluggable routing, eliminating callback-based patterns in favor of async/await semantics.
Developers should choose aiohttp when building I/O-bound applications that benefit from concurrency, such as services making many simultaneous HTTP requests or web servers handling numerous concurrent connections. It suits projects already using asyncio or those where non-blocking I/O is a core requirement. The README contrasts its approach with the requests library, noting that aiohttp requires more explicit session management and awaiting because it operates asynchronously rather than synchronously.
The project maintains active continuous integration with automated testing and code coverage tracking. Development activity shows consistent engagement with community discussions and multiple communication channels for support and coordination.
