When you get a chance, please check out our new Redux Starter Kit package. It includes utilities to simplify several common Redux use cases, including store setup, defining reducers, immutable update logic, and even creating entire "slices" of state at once:

https://redux-starter-kit.js.org

It's also written in TypeScript itself, so it works well for TS usage. It doesn't do as much strict magical inference as something like `typesafe-actions`, but it should be very usable.

I recently wrote a small example "Github issues" app that's written in TS and uses Redux Starter Kit and our new React-Redux hooks API, if you'd like to see how the code looks:

In particular, here's an example of RSK's `createSlice()` API in action, with TS and some thunks:
