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.
It's not tutorial-style, but it does contain hundreds of sample web apps (that all do the same thing, but still)
