Description

This is a mod that enables usage of the Javscript programming language and debugger tools for Fabric mods.

This is still being developed and tested. If you have any issues or are missing any features, please contact me on discord

For an example mod please checkout this github repo

Roadmap

  • Debugging directly in the code (VsCode or Intellij)
  • Support mixins
  • Custom registries (new blocks, items, entities, GUIs)
  • Client-side rendering
  • Networking — custom packets between client/server.

ThreadJS weaves JavaScript into Fabric.
