As it turns out, you can use Redux Toolkit even if you're not using a Redux store!
A reducer is, ultimately, just a function. It doesn't matter if that function is implemented using vanilla JS, Immer, Ramda, Lodash/FP, or something else.
I've used Redux Toolkit's createSlice API multiple times to create reducers that were only meant for use with the useReducer hook in a React component, in apps that weren't using a Redux store at all.
If you're looking at using Immer to write a reducer, you should seriously consider just using createSlice instead of calling produce yourself. createSlice adds minimal extra runtime overhead beyond Immer by itself, and works great with TypeScript as well.
