Recently I had the chance to put together my first working Rodauth setup in a Hanami app! 
My focus was to make it feel as streamlined within Hanami as possible. This meant: requiring authentication from within actions, and making sure Rodauth’s templates are rendered by Hanami views.
All the code is now available in decafsucks/decafsucks (my hobby app), and I just wrote a full blog post explaining the setup: Rodauth, meet Hanami.
I hope this is useful!
And if any of you are interested in helping to create a rodauth-hanami gem, hit me up and I can help you out
