ES6 module compatibility

[vorth]

I'm pulling J4TS into my project as a Maven dependency, and it works fine* as long as I use JSweet with module=none. If I turn on module=commonjs or module=es2015, the errors from the transpiler are very different, as if it couldn't see J4TS at all. Is there something else I need to do so that the J4TS dependency works with module=commonjs?

I saw somewhere in a README here that J4TS is "module compatible". It looks like that means it is published on NPM, so I suppose a commonjs module. I can see how I could benefit from that in my client build, but that doesn't help me transpile with J4TS.

I should note, I did find the language spec section on modules, but that seems to apply only to the "def" package for bindings, and it is not clear whether it addresses compile-time dependencies at all.

*I do get some errors about java.util.StringTokenizer, which now seem odd, since I see that StringTokenizer is part of J4TS.

I resolved the StringTokenizer issue by copy/pasting the java implementation here:

https://github.com/j4ts/j4ts/blob/8a371ac068834d5d36dae762e2f197a160ca95bf/src/main/java/java/util/StringTokenizer.java

into a new class in my java project.

Similar to what you describe, I can build individual files and make a bundle, but if I use the es2015, I suddenly get hundreds of errors, e.g. Cannot find name 'ArrayList'.
