What does this mod do?

This mod lets you create scripts in JavaScript language to manage your server, add new blocks and items, change recipes, add custom handlers for quest mods and more!

How to use it?

Run the game with mod installed once. It should generate kubejs folder in your minecraft directory with example scripts. startup scripts only get run once when the game loads. Those are for registering items, setting up configs etc. Server/data scripts are loaded when you join a world, those are better for things like clearlag, displaying custom login messages and world/player related things in general.

Can I reload scripts?

Yes, use /reload. Note: Not everything is reloadable. Some things require you to restart game, some only world, some work on fly.

I don't know JavaScript / I need help with this mod

There are examples and pre-made scripts on KubeJS Wiki.

How complete is this comparing to KubeJS Forge?

KubeJS fabric is complete on adding new blocks and items, changing recipes and managing blocks, and items tags. For events, only a small amount has been implemented, view the implemented events here.

How does this mod work?

It uses Nashorn, built-in JavaScript parser to read scripts, shipped with Java 8 and above. There shouldn't be a case where this doesn't exist in your Minecraft, but if that's the case, please report!

Ok, but what if it.. doesn't work?

You can report issues on GitHub.

I have more questions/suggestions!

If wiki didn't have the answer for what you were looking for, you can join the Discord server and ask for help on #kubejs-and-code channel!
