API and Library

Graal

is a customized version of GraalJS, a high performance JavaScript implementation. It is ECMAScript-compliant, provides interoperability with Java and other Graal languages.

On top of regular GraalJS features, Graal made these improvements:

  • MemberRemapper support, allowing developers to customize the JavaScript side name of a Java member, like Method and Field
  • Trimmed bundled libraries, making the total mod size ~50% smaller than regular GraalJS

GraalJS Documentation: https://www.graalvm.org/reference-manual/js/

Attention

  1. This is NOT GraalJS or GraalVM. If you encounter issues that are not related to JavaScript itself, send issues to GraalMC GitHub repo before contacting GraalJS or GraalVM
  2. (Fixed in 25.0.2.0) If you are running the game with GraalVM, the game will crash early
