Asyncer is a small library built on top of AnyIO. Asyncer has a small number of utility functions that allow working with async, await, and concurrent code in a more convenient way under my (@tiangolo - Sebastián Ramírez) very opinionated and subjective point of view. The main goal of Asyncer is to improve developer experience by providing better support for autocompletion and inline errors in the editor, and more certainty that the code is bug-free by providing better support for type checking tools like mypy. Asyncer also tries to improve convenience and simplicity when working with async code mixed with regular blocking code, allowing to use them together in a simpler way... again, under my very subjective point of view.
