The source is absolutely available: https://github.com/WhiteWhiskey/rack_app

There is also a link to GitHub on the app.

  Learning resources:
    https://careerfoundry.com
    https://www.railstutorial.org/book
    https://learnrubythehardway.org/book/
    Browsing GitHub

  Books I've bought:
    O'Reilly Ruby Cookbook
    The Well-Grounded Rubyist
    Beginning Ruby
      From Novice to Professional Third Edition
    Practical Object-Oriented Design in Ruby: An Agile Primer

If you look through the source code I would enjoy feedback good or bad. I have not been able to find any resources that get past 'hello world' with rack. So what I have wrote was learned from those hello world apps combined with browsing GitHub. I have no idea if I am doing things right or not but it works for now.
