What it does

ZJS is a JavaScript modding framework for live scripting of the Minecraft client. It includes libraries, wrappers and objects that make scripting easier, and covers a subset of the features of the original ChatTriggers mod, with many features removed. The project supports 26.1.2 – 26.2 and is released under the MIT License as open source. Fabric API and Fabric Language Kotlin are both required.

Key features

  1. Live client scripting

    Scripts written in JavaScript can modify the client while the game is running, without a restart.

  2. Helper libraries

    Wrappers and objects bundled with the framework reduce the code needed for common modding tasks.

  3. Reduced ChatTriggers subset

    The fork keeps only part of the original ChatTriggers feature set, so it is smaller than the full mod.
