I am ''finally'' learning a web framework! We are diving into [https://pzwiki.wdka.nl/mediadesign/Prototyping/2025-2026/T3 during the prototyping classes of XPUB Special Issue 30].

This is a sparse collection of notes that complements the wiki pages from the course.

The source code I have been tinkering with is [https://git.xpub.nl/tommi/flask-intro here].

By default, Flask runs <code>app.py</code>. It’s possible to define a different app with <code>--app</code> flag.

<pre class="zsh">uv run --app main --debug</pre>
It is mind-blowing, game-changing for me to learn how the Web works by making little things step-by-step with a software, in this case Flask.

What I am referring to is understanding [https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Methods HTTP request methods], which honestly seemed conceptually sound, yet very abstract and impractical so far. Implementing this methods in Flask and experimenting together in a simple form is what made things click in my head.

It is fascinating to observe how <code>@app.route</code> handles requests behind the scenes, and how to channel those requests into changes that are then visible in the web page(s).
