In the JS version of this there is discussion regarding a dev mode that compiles the app and just writes the result to disk whilst watching rather than serving direct from webpack-dev-server, the rationale being that perhaps you want to integrate your react app with a backend so it's helpful to have your backend server serve your frontend files locally.

Others have contributed scripts which defer to react-scripts but it's not obvious how to get this to work when TypeScript is involved.

Is there a possibility of adding a watch mode or devising a way to do this?
