I've used it because my uni still forces us to use Java (https://github.com/alphahorizonio/jnebulark) but the experience hasn't been that great for the actual framework (bindings are way to hard to do; I haven't found a way to do Promises yet, see https://github.com/alphahorizonio/jnebulark/blob/main/src/ma...). In general, docs are lacking quite a bit as well (you have to use the development version for most things now, which isn't in sync with the docs). We just took the sane route, wrote the backend in TypeScript (and ported to Java for Uni), and used React for the frontend. The WebAssembly support of TeaVM is fun to use for small modules though, we integrated it into a WIP project: https://docs.webnetes.dev/getting-started/develop/java.html
"I haven't found a way to do promises yet". TeaVM provides Java wrappers for most JS APIs, including promises (https://github.com/konsoletyper/teavm/blob/master/core/src/m...). If you require an API that doesn't have a wrapper yet, it is dead simple to create your own wrapper. Or just use the @JSBody annotation to write your own ad-hoc Javascript.
Thanks for the link! This looks like a significant improvement over my current solution of trying to pass callbacks ... which aren’t transferable types sadly ;)
