However, you can reference this post to learn how to create Redux apps with Redux Toolkit. You’ll need to have some knowledge about Redux to understand Redux Toolkit. Redux Toolkit builds in our suggested best practices, simplifies most. The reduxjs/toolkit package wraps around the core redux package, and contains API methods and common dependencies that we think are essential for building a Redux app. That doesn't work well with createSlice() right now, because it tries to generate action creators and action types based on the reducer names, and the reducers only respond to those actions. In this article, you’ll learn how to use the createAsyncThunk API to perform asynchronous tasks in Redux apps. Redux Toolkit (also known as 'RTK' for short) is our official recommended approach for writing Redux logic. As a more specific example, let's say you want to handle async request status (ie, 'REQUESTSTARTED / SUCCESS / FAILURE' actions. With Redux Toolkit, Redux Thunk is included by default, allowing createAsyncThunk to perform delayed, asynchronous logic before sending the processed result to the reducers. A middleware is designed to enable developers to write logic that has side effects - which refers to any external interaction outside an existing client application, like fetching data from an API. Middleware has since been used in Redux applications to perform asynchronous tasks, with Redux Thunk’s middleware being the most popular package. Using the fetchUserById example above, createAsyncThunk will generate four functions: fetchUserById, the thunk action creator that kicks off. The thunk action creator function will have plain action creators for the pending, fulfilled, and rejected cases attached as nested fields. Redux eschews handling asynchronous logic simply because it doesn’t know what you want to do with the data you fetched, let alone if it’s ever fetched - hello, errors. createAsyncThunk returns a standard Redux thunk action creator. weixin43077745: testApiparams reduxjs/toolkitcreateSlicecreateAsyncThunk.
