I wrote all of this from scratch myself
This list is non-exhaustive, and likely always will be. Many of my personal projects are interesting only really to me and people who are super invested into things like serverless functions and automation. Most of my public code is on GitHub, but here's some highlights:
Sleetcord
A bot framework built on Discord.js. Used in all my bots, it handles interaction/event registering, routing, and handling, massively simplifying building modular bots. Publicly available, but is mainly meant for personal use.
Booru
booru is a Node.js package to easily interface with the APIs of several boorus
Create-a-Chart
A SPA to create a chart with labeled points, for alignment charts or whatever else. Made with Preact, hosted on Cloudflare pages.
Bots
Mostly utility and moderation tools for Discord, with some 'fun' commands thrown in too.
