I have updated this sample to Angular 18. It continues to use gojs-angular 2.0.7.
If you want to use GoJS v3, there's a bug in the Babel transpiler/minimizer. You will need to use at least v3.0.5, unless you use an Overview, in which case you'll need at least v3.0.6, which include work-arounds for that Babel bug.
