I just finished writing a discord bot backed by postgres with a web frontend. Some friends and I like to do watch parties and this system lets you set a theme for a group of movies, everyone submits their picks, then it will randomize and post what the agenda is each week. Afterwards it posts a poll to let them respond with a thumbs up or down. The next thing on my list is to use the voting data to render a user score based on how well their picks were received by the group lol.
I got really interested in this idea when I decided to write it in a stack I don't normally work in, Go + HTMX. Go routines are incredibly useful. I used https://nostalgic-css.github.io/NES.css/ for the front end and it's really become a fun bot all around.
