Tyrian is aimed to compile TypeScript to runnable code on JVM (and also web browser). You can program the server-side in TypeScript while using libraries fromMaven andNPM together.

To make it clear, I'd like to quote fromsparkjava.com:

Lately, a lot of server-side web development has been taken over by NodeJS, but a growing number of NodeJS developers are using TypeScript and other statically typed languages that compile to JavaScript. Why not go all the way and usea language that was actually designed with types, and intended to run on the server-side? You also get all thebenefits of running your application on the JVM, where libraries aren’t deprecated every day.

Here is what tyrian can offer: you can have TypeScript for the server-side (likedeno) and run it on the JVM.

Tyrian can generate TypeScript definitions for Maven dependencies so that you can enable the autocomplete feature in IDE.
