What is Redux Toolkit and how do I use it with TypeScript?

Redux Toolkit is a library that simplifies Redux development. It provides tools to create slices, reducers, and actions easily, especially when using TypeScript.

Can you show me a simple example of a Redux slice in TypeScript?

Sure! Here's a basic example:

import { createSlice, PayloadAction } from '@reduxjs/toolkit';

interface CounterState {
  value: number;
}

const initialState: CounterState = { value: 0 };

const counterSlice = createSlice({
  name: 'counter',
  initialState,
  reducers: {
    increment: (state) => {
      state.value += 1;
    },
    decrement: (state) => {
      state.value -= 1;
    },
    incrementByAmount: (state, action: PayloadAction<number>) => {
      state.value += action.payload;
    },
  },
});

export const { increment, decrement, incrementByAmount } = counterSlice.actions;
export default counterSlice.reducer;

How do I integrate this slice into my store?

You can integrate the slice into your store like this:

import { configureStore } from '@reduxjs/toolkit';
import counterReducer from './counterSlice';

const store = configureStore({
  reducer: {
    counter: counterReducer,
  },
});

export default store;
