🚀 Context Manager to run `uvicorn` ASGI applications

🚀 Context Manager to run uvicorn ASGI applications

uvicorn_context_manager is a Python package that exposes a class named UvicornContextManager that inherits from uvicorn.Server and contains a Python context manager to deploy an ASGI application inside a context and then gracefully shut it down.

The motivation was to provide a way to easily deploy an ASGI application when running tests or wanting to interact temporarily with ASGI applications.

This could have been a GitHub Gist or just a code snippet, but I think that this can be useful for many uvicorn users, and it just contains the uvicorn dependency so there's no overhead.

⚒️ Installation

Python greater than 3.7 and lower than 3.11

pip install uvicorn_context_manager

Or install it in development mode as:

pip install -e .

👨🏻‍💻 Usage

⚡️ With fastapi

As mentioned before, the context manager as uvicorn, lets you deploy any ASGI application. Since fastapi is one of the most used Python frameworks for web development according to a JetBrains survey, see https://twitter.com/tiangolo/status/1624002347776065538.

So on, we think it's useful to showcase how to use uvicorn_context_manager with fastapi.

pip install fastapi

Once installed, you can deploy your ASGI application in a Python context manager as:

from fastapi import FastAPI
from uvicorn_context_manager import UvicornContextManager

api = FastAPI()
with UvicornContextManager(api) as server:
    ...
