Command Line Interface

$ blu

When you install Blu, the Blu command line interface (CLI) will also be installed and made available in your system path as blu.

Run blu from your project root (the directory containing the app/ directory) to start a development server that runs your app and restarts any time a change is made to Python files in your app directory.

The deveopment server will automatically find an available port to run on, and once it has started, the blu process will give you output like the following, showing the URL where your app is running:

INFO:     Uvicorn running on http://127.0.0.1:50227 (Press CTRL+C to quit)

Don’t run the development server in production. See Deploying Your App for details on how to deploy an app to a production environment.
