Typing Redux Toolkit Slices and Thunks
Use createSlice and createAsyncThunk with full type inference.
Why Type Redux Toolkit?
Redux Toolkit (RTK) includes excellent TypeScript support. Proper typing ensures actions, state, and async thunks are all type-safe without manual type assertions.
import { createSlice, createAsyncThunk } from "@reduxjs/toolkit";Typing the State Interface
Define your slice state as a TypeScript interface before creating the slice.
interface UserState {
users: User[];
loading: boolean;
error: string | null;
}
const initialState: UserState = {
users: [],
loading: false,
error: null,
