Call an action from another action using Redux Toolkit
There are multiple ways to call an action from another action using Redux Toolkit. Here, we’ll discuss two different methods with a small example.
Way to call an action from another action
1. Using dispatch function
In Redux Toolkit, you can use the dispatch function to call an action from another action. Here is an example of how to do this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | import { createAsyncThunk } from "@reduxjs/toolkit"; // define the first action export const fetchUser = createAsyncThunk("user/fetchUser", async () => { // make an API call to fetch the user data }); // define the second action that calls the first action export const updateUser = createAsyncThunk("user/updateUser", async (userId, { dispatch }) => { // make an API call to update the user data // then fetch the updated user data by calling the fetchUser action await dispatch(fetchUser()); }); // define the user slice const userSlice = createSlice({ name: "user", initialState: {}, reducers: {}, extraReducers: { <strong>Â Â </strong><code>// handle actions }, }); |
In the above example, we have two actions: fetchUser and updateUser. The updateUser action takes a userId parameter and a dispatch parameter, which is provided by Redux Toolkit. Inside the updateUser action, we make an API call to update the user data and then call the fetchUser action using dispatch to fetch the updated user data.
To handle these actions in the user slice, we use the extraReducers field in createSlice to listen for the fulfilled action of each of these actions and update the state accordingly.
Overall, Redux Toolkit makes it easy to call actions from other actions using the dispatch function, allowing you to easily manage complex state changes in your Redux store.
2. Using createAction function
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | import { createAsyncThunk, createAction } from "@reduxjs/toolkit"; // define the first action export const fetchUser = createAsyncThunk("user/fetchUser", async () => {  // make an API call to fetch the user data }); // define the second action export const updateUser = createAsyncThunk("user/updateUser", async (userId, { dispatch }) => {  // make an API call to update the user data }); // Define the action that call both actions export const updateAndFetchUser = createAction(  "user/updateAndFetchUser",  async (userId, dispatch) => {   await dispatch(updateUser(userId));   await dispatch(fetchUser());  } ); // define the user slice const userSlice = createSlice({  name: "user",  initialState: {},  reducers: {},  extraReducers: {   // handle actions  }, }); |
In the above example, the updateAndFetchUser action calls the updateUser and fetchUser actions using the dispatch function passed as an argument. This way, you can call one action from another and orchestrate more complex behavior in your Redux store.
