Note

pypy3 is also supported

ASGI-Tools belongs to the category of ASGI web frameworks, so it requires an ASGI HTTP server to run, such as uvicorn, daphne, or hypercorn.

Installation

asgi-tools should be installed using pip:

pip install asgi-tools

A Quick Example

You can use any of ASGI-Tools components independently.

ASGI-Tools also includes an App helper to quickly build ASGI applications. For instance:

Save this to app.py.

from asgi_tools import App

app = App()

@app.route('/')
async def hello(request):
    return "Hello World!"

Run it with uvicorn

$ uvicorn app:app
