how to call an action from another action slice in redux

const counter = createSlice({

  name: ‘counter’,

  initialState: 0 as number,

  reducers: {

    increment: (state) => state + 1,

    decrement: (state) => state – 1,

    multiply: {

      reducer: (state, action: PayloadAction) => state * action.payload,

      prepare: (value?: number) => ({ payload: value || 2 }), // fallback if the payload is a falsy value

    },

  },

  // “builder callback API”, recommended for TypeScript users

  extraReducers: (builder) => {

    builder.addCase(incrementBy, (state, action) => {

      return state + action.payload

    })

    builder.addCase(decrementBy, (state, action) => {

      return state – action.payload

    })

  },

})

const user = createSlice({

  name: ‘user’,

  initialState: { name: ”, age: 20 },

  reducers: {

    setUserName: (state, action) => {

      state.name = action.payload // mutate the state all you want with immer

    },

  },

  // “map object API”

  extraReducers: {

    // @ts-expect-error in TypeScript, this would need to be [counter.actions.increment.type]

    [counter.actions.increment]: (

      state,

      action /* action will be inferred as “any”, as the map notation does not contain type information */

    ) => {

      state.age += 1

    },

  },

})
