FWIW, this process can be simplified greatly, on several levels.

First, we already have a Redux+TS template for Create-React-App: github.com/reduxjs/cra-template-redux-typescript . It comes with Redux Toolkit and React-Redux already configured.

Second, the examples here are actually going against how we recommend writing Redux code.

• Redux Toolkit is installed, but it's not being used at all to write the reducers
• You should be using the createSlice API, which will also auto-generate the action creators for you
• createSlice uses Immer inside, so you can "mutate" the state inside of the reducer instead of having to write spread operations for immutable updates
• The logic should be organized into single-file "slice" files per feature - no need for separate "actions" and "action-creators" files.
