Why a focus on frontend only? I am using Typescript, Babel, Jest and a bundler for any app/library on the frontend/backend. If you got to do it, do it all the way! I can already see the GH issues, “sorry, this is a backend use case”. So now my tooling would end up being more complex with the addition of another tool since it will never support all my use cases. Seemed promising but this alone makes me question its utility.
