This document explains my environment and workflow for handling upgrades to AEL's Hubs Cloud instance.

Overview

hubs.aelatgt.net includes source modifications to support script injection and a handful of project-specific tweaks. This allows developers to add new behaviors on a room-by-room basis without having to rebuild the client. Some projects require access to internal client logic, which we expose on a global APP.utils object.

Environment

I have multiple Git remotes configured so I can maneuver between the Mozilla and AEL repos:
