This is a demo of FastComments SSO in a very simple Python 3 app. It is written w/ Python 3.8.
It only uses the standard library.
See fastcomments_sso.py for how to create the SSO payload server-side.
See server.py for how to pass the SSO payload to FastComments client-side.
In server.py we just send back HTML with the widget JSON payload pre-populated, as an example of simple server-side-rendering.
You could instead render the page and call an API that calls get_fast_comments_config_with_secure_sso_payload.
This will work as-is since it uses a pre-created demo account, however in production you'd have to define your own secret key and tenant id.
You may set your own api key and tenant id in fastcomments_sso.py.
To run, run python server.py and open http://localhost:8000.
