Mod KubeJS

KubeJS, JavaScript control for Minecraft

KubeJS is a Minecraft Java Edition mod that lets creators customize a modpack or Minecraft server through JavaScript scripts. It can add, remove, or replace recipes, adjust tags, register custom items and blocks, and connect with supported mods.

Its event system also handles gameplay logic, including player interactions, commands, world changes, and generation tweaks. Startup scripts register content, while server scripts manage live events and can often be refreshed with /reload. For BoxToPlay communities, KubeJS is a flexible way to shape progression, balance crafting, and build distinctive server experiences without modifying every mod directly.
