This is an example of a web server that utilizes asyncio processing using the Falcon web framework and running on uvicorn ASGI web server.
Create a virtualenv: python -m venv venv
Activate it: . venv/bin/activate
Install base requirements: pip install -r requirements.txt
Run the run.sh script to start the app.
Both App and Uvicorn configuration should reside in an optional conf.d directory that resides in the CWD of the app and is not committed to source control.
To configure uvicorn copy the example in examples/uvicorn to your conf.d/ directory and modify it accordingly.
To configure the app copy the example in examples/config.json.example to conf.d/config.json modify it accordingly.

└── run.shThe app/app.py module contains the main initialization code - including config loading and CORS setup - which also starts the falcon framework.
The app/asgi.py module creates the falcon app and is executed by the ASGI server.
The app/config.py module defines a Config class that you should extend with your own config parameters.
The app/constants.py module is the place to define app constants.
The app/utils module contains submodules that define some useful functions for working with async Python code.
The app/middleware module is where middleware classes should be placed, it contains a default task_starter.py module to help with async initialization of controllers.
The app/resources module is where endpoint controllers should be placed, it contains a simple healthcheck endpoint and an example of a controller with suffix endpoints.
The examples folder contains example configuration files for the app and for uvicorn.
The examples/uvicorn is a simple script that can be sourced to configure uvicorn at run time.
The examples/config.json.example is a template for the JSON configuration file the app tries to read on startup.
