Last week I gave talk about how I made a web app for our tiled and woven maps work1 to the Wellington Python meetup held at the Sharesies office on the third Thursday of every month.

The talk was recorded, although the original was pretty choppy as a result of some weird interactions between google meet, macos workspaces, and full screen browser windows (or something) so the below is a re-recording I made the day after.

If you are mostly interested in how you can make a web app in pure python while writing no javascript, then skip to about 19 minutes in where I talk about marimo and more or less competently demonstrate how easy it is to do. I recently posted about marimo when I first encountered it two or three months ago.

The app itself is here. Be patient: it takes a little while to load, which is why I wrote almost no javascript. The little I did write is to show a splash screen while the app loads in the background!

  1. I should note here as I somehow failed to do in the talk that the tiled and woven maps work is in collaboration with Luke Bergmann at UBC in Canada.↩︎
