ScriptableMC-Engine

Run JavaScript/TypeScript plugins for Minecraft 1.15 using the GraalJS script engine.
Supported Minecraft Versions: Bukkit/Spigot/Paper 1.12, 1.13, 1.14, 1.15
Untested but should work: 1.8+

This plugin is in a preview state, there may be breaking changes, missing features, and possibly a few bugs.
Feel free to create an issue if you find any missing features, bugs, or just have an idea for a great feature to add.

This plugin requires running your minecraft server with OpenJDK, Standard JDK, or the GraalVM java runtime.
Most linux servers already use OpenJDK, however if you're running windows or want a fully supported java runtime that supports AOT javascript compilation you can install GraalVM-CE.

GraalVM-CE is a free open source java runtime created by Oracle that is pre-packaged with the GraalJS Engine allowing all javascript engine features including AOT compilation of javascript.

Installing The JavaScript Engine Plugin

If your server is running on a Standard JDK

Download the latest ScriptableMC-Engine-JS-Bundled.jar and place it in your plugins folder.

If your server is running on a GraalVM JDK

Download the latest ScriptableMC-Engine-JS.jar and place it in your plugins folder.

Take a look at ScriptableMC-TypeScript for a full typescript plugin example. You can take the typescript example and compile it, then directly modify the javascript if you don't want to use typescript.
