Django を Uvicorn とともに使う

Uvicorn は uvloop と httptools をベースにした速度重視のASGIサーバーです。

Uvicorn のインストール

pip で Uvicorn をインストールします:

python -m pip install uvicorn

Uvicorn で Django を実行

When Uvicorn is installed, a uvicorn command is available which runs ASGI applications. Uvicorn needs to be called with the location of a module containing an ASGI application object, followed by what the application is called (separated by a colon).

For a typical Django project, invoking Uvicorn would look like:

python -m uvicorn myproject.asgi:application

This will start one process listening on 127.0.0.1:8000. It requires that your project be on the Python path; to ensure that run this command from the same directory as your manage.py file.

In development mode, you can add --reload to cause the server to reload any time a file is changed on disk.

For more advanced usage, please read the Uvicorn documentation.

Deploying Django using Uvicorn and Gunicorn

Gunicorn は、プロセス監視と自動再起動を実装した堅牢なウェブサーバーです。本番環境でUvicornを運用する際に役立ちます。

To install Uvicorn and Gunicorn, use the following:

python -m pip install uvicorn gunicorn

Then start Gunicorn using the Uvicorn worker class like this:

python -m gunicorn myproject.asgi:application -k uvicorn.workers.UvicornWorker
