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
- 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
- (Fixed in 25.0.2.0) If you are running the game with GraalVM, the game will crash early
