Have you done any work with Vue and Typescript? We're just starting out with Vue. But my understanding was that TypeScript is a first class citizen in the new version of Vue.
TS isn't a first-class citizen in 2.x, and you'll need to go through a couple of awkward maneuvers to prevent Vue from negating many of the benefits of TS, but it can absolutely be done. This sample project sums it up nicely: https://github.com/Armour/vue-typescript-admin-template
Looks like 3.x plans to be built on typescript but I'm not sure if this article is still relevant, I very recently started paying serious attention to Vue.js so I'm playing a game of drink from a fire-hose.
