KubeJS Additions
This mod aims to provide pack makers with additional functionality not in KubeJS already. A key feature is that it allows you to listen to any arbitrary Fabric or Architectury Event, making the event listening possibilities endless!
About this Mod
KubeJS Additions adds more events and methods to KubeJS to make it easier for pack creators to do things such as toggling force-loaded chunks or getting ticking chunks, adding additional checks for blocks and entities, adding player stats, toggling a player's elytra, messing with JEI and more!
You can now listen to any Fabric or Arch event in 1.18.2 or 1.19.2
Examples and documentation for this mod can be found on GitHub here
You can also find a full list of examples for listening to arch and fabric events on KubeJS's discord in this thread.

KubeJS Additions server crashes on startup – what to do?

KubeJS Additions officially supports fabric, forge, neoforge for Minecraft 1.21.1, 1.21, 1.20.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with KubeJS Additions – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if KubeJS Additions consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
