GraalJS
by anmao
GraalJS packages a JavaScript language library so that other mods can run GraalJS code without bundling it themselves.
What it does
The library provides a JavaScript language runtime based on GraalJS. Mods that use GraalJS can depend on this package instead of shipping their own copy, which keeps each mod's file size smaller. Builds are published for Forge and NeoForge, covering the game versions 1.20.1 – 26.2 across 15 release versions. Either side can load it, and a server or a client does not require it to be present.
