Example integration with Starlette or FastAPI

If you open FastAPI source code you find it's subclass of Starlette. That's why I don't separate them

Implementing Unit class

For example, the name of following file is starlette_app.py

from systempy.unit.ext.starlette import StarletteUnit

# It's advice to define all your apps in separated file(s)
# having this instance and nothing else. I think it's the
# easiest way to avoid circular imports
from .starlette_instance import app as starlette_app

from . import views
# Linters some why don't know that imports has side effects
views.__package__


class  MyStarletteApp(StarletteUnit):
    """
    Optionally you can define lifecycle actions. These actions you can split
    into your own mixins. Then you organize own mixins into own collection and
    then your application `Unit` will be a combination of 4-6 or more mixins.
    Congrats! This is the most typical `systemPY` usage
    """


# StarletteUnit relies on keyword argument starlette_app
unit = MyStarletteApp(
    starlette_app=starlette_app,
)

Running the app

Then run webserver:

uvicorn starlette_app:starlette_app
