Twitter API
It's very convenient how a HTML/CSS/JS project on repl.it is automatically hosted, so there's no need to explicitly set up a back end (Hello World example here, viewable here).
I've been wanting to play around with Twitter's API, and thought setting up the client JavaScript to make the API call keeps things simple. Annoyingly .env files for HTML/CSS/JS projects get exposed and the more interesting parts of the API is behind the auth.
OK so I'll need my own back end. It turns out this is not too complicated. I stitched together a minimal Flask web server that dumps the response in the HTML (project here, viewable here).
