TypeScript with JSPM and VS.NET works great, IMO even better than Babel since it doesn't require additional configuration for Babel or managing a separate watcher process since VS.NET compiles on save - providing an optimal dev experience. The additional complexity TypeScript requires is typings for each library which is designed to add value over time through typing feedback, but sometimes the typings can deviate from the implementation which is currently the only friction I hit when using TypeScript. If you're interested in this combination, I've published a step-by-step guide showing how all pieces fit together in: https://github.com/ServiceStackApps/typescript-redux https://github.com/ServiceStackApps/typescript-redux For a decent sized TypeScript + React code-base checkout https://github.com/ServiceStack/Gistlyn https://github.com/ServiceStack/Gistlyn - a C# Gist IDE written in TypeScript + React and Redux - a large enough project that would've been painful to write without React or TypeScript.
