Looking at those, it seems the sample apps are way more complex than what I envision. The Django one starts with these dependencies:

    Django==3.1.12
    greenlet==0.4.17
    gunicorn==20.0.4
    meinheld==1.0.2
    mysqlclient==1.4.6
    psycopg2==2.8.6
    pytz==2020.4
    ujson==4.0.1

The approach I want to show is: What are the minimal steps to get a working web application with routes, templates and user accounts. I know that at least for Django, this is possible with no additional dependencies.
