Setting Up A Kowloon Server

Setting Up Your Own Kowloon Server

Setting Up Your Own Kowloon Server

This guide assumes you can open a terminal, log into a remote server over SSH, and run commands. You do not need to be a Linux expert or know anything about Docker.

What you will need before you start

A server or VPS. Kowloon runs on any Linux server or Mac running macOS 13 or later. A $6/month VPS from DigitalOcean, Linode, or Hetzner is fine for a small community. You will need at least 1 GB of RAM and 20 GB of disk. Two gigabytes of RAM is more comfortable.

Boilerplate for simple Mongoose user schema
/*
I find myself recreating user models for Mongoose every time I start a new project, so I thought I'd create a generic schema for a user model that can be added to or modified as need be.
This is loosely based on the Meteor user model (using a "profile" sub-object for the user's personal information). It also includes an optional geolocation point for the user, and Mongoose timestamps, as well as a pre("save") function to bcrypt the user password and a comparePassword() function.
Just save this file wherever you store your models and do something like const Users = include('./models/userSchema.js') and you can just use it as a standard Mongoose user model.
The username/email address definitions were copied from this tutorial: https://thinkster.io/tutorials/node-json-api/creating-the-user-model

Given an array of numeric arrays and a decimal value between 0 and max, returns a "morph" of the arrays at a point on the continuum of the arrays at that point. Used to emulate the waveform knob on a Moog synthesizer.
// These are just examples.
var arrays = [
[0.64, 0.02, 0.1, 0, 0.9, 0, 0.09, 0, 0.07, 0, 0.06, 0, 0.05, 0],
[0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[0.81, 0, -0.09, 0, 0.03, 0, -0.02, 0, 0.01, 0, -0.01, 0, 0, 0],
[-0.32, -0.16, -0.11, -0.08, -0.06, -0.05, -0.05, -0.04, -0.04, -0.03, -0.03, -0.02, -0.02]
];
var arrayMorph = function(value, max, arrays) {
current = [];
