AIOHTTP
Aiohttp is an asynchronous HTTP client/server for the Asyncio module. It is a Python library that is needed to execute client requests and create a web server with streaming output and websockets.
In simple terms, Aiohttp is a technology that helps an application (server) and its users (clients) communicate faster and exchange data. The performance of your web project depends on how well this communication is implemented.
There are several ways to implement an HTTP client for Python projects, but Aiohttp is the most popular solution, fast and scalable, and is used almost by default.
Asynchronization is needed to perform several operations, establishing connections simultaneously without waiting for the previous ones to complete. Using this approach increases the speed of web services by several times, the reason for the low performance of which is usually not complex calculations, but waiting for input/output.
A single solution for implementing an HTTP server and client
Support for server and client websockets out of the box, without callback hell
Middleware for a web server with signaling and routing that connects
A simple and convenient solution for modeling the level of high parallelism in Python projects that do not have multithreading.
Aiohttp is a Python library based on Asyncio technology. It is used to create asynchronous HTTP clients/servers. It is a backend development technology for optimizing work with a large number of simultaneous requests. Every application needs it so that your users don't have to wait several minutes for each of their tasks to be completed. In some projects, you can use other options for implementing HTTP client/servers for Python projects, but in any case, this decision should be entrusted to developers.
