Today, the JSweet transpiler source code was pushed to github.

This first version is the outcome of a lot of work on my private repo, so it comes out quite mature already, even if a lot of work will still be required, as expected.

JSweet relies on the TSD (TypeScript’s DefinitelyTyped) to access the JavaScript APIs from Java. The TSD to Java translator is not Open Source yet, but the Java APIs are.
