I think most of this can be solved by proptypes, although true proptypes is not as thorough as TypeScript.

I had some negative experiences with typescript in a large React project but in that case the most negative experience was that often the type definitions provided by React and common type libraries didn't match our needs, which made doing something that would normally be quick difficult and long.

The reason for types not matching was often that we needed to generate HTML emails as part of things, which means you need a lot of deprecated attributes, so probably you won't have this problem.
