mpp-server-dev2

This is an MPP server currently in development for MPP.dev. The original server is old and the site desperately needs a new one.

This server uses Bun - not just the runtime, but the libraries as well. This is because Bun provides easy access to uWebSockets.js, a speedy implementation of WebSockets that heavily outperforms the old ws module that is used so frequently.

I have tried to comply well with Brandon Lockaby's original MPP server so that this server stays widely accessible for any frontend implementation, including the ones used by MultiplayerPiano.net, LapisHusky's frontend, and the frontends used by nagalun's server, as well as the smnmpp and mpp.hri7566.info frontends.

Of course, most of the ones I have listed probably won't work yet because I haven't implemented a way to switch between token authentication and legacy connections yet.

Regardless, this server is meant for speed, stability, and compatability.

This server uses Prisma as an ORM for saving user data, and is currently setup to interface with SQLite. I may be switching this to PostgreSQL in the very near future, so don't get too comfortable with SQLite.

Brandon's server originally used MongoDB for storing user data, but there are too many reasons to list why it isn't fit for this project here, so I will link this video by Theo instead.
