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. createSlice takes an object of reducer functions, a slice name, and an initial state value and lets us auto-generate action types and action creators, based on the names of the reducer functions that we supply. Redux Toolkit (also known as 'RTK' for short) is our official recommended approach for writing Redux logic.
What exactly helps developers to write code faster, easier, more clearly One of the helpers is createSlice function. Also, if any other part of the application happens to dispatch an action Redux Toolkit popularity is growing every month. The keys in the object will be used to generate string action type constants, and these will show up in the ReduxĭevTools Extension when they are dispatched. reducers Īn object containing Redux "case reducer" functions (functions intended to handle a specific action type, equivalent I will be keeping the feature naming for the counter, and will be renaming the file from counter.js.
REDUXJS TOOLKIT CREATESLICE UPDATE
Generated action type constants will use this as a prefix. A basic createSlice methods takes in the following: name: which is name of the slice for reference initialState: the initial state of the reducer reducers: contains all the actions to mutate the reducer state Lets update the repo to a slice. 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. name Ī string name for this slice of state. createAsyncThunk returns a standard Redux thunk action creator. This will be used whenever the reducer is called with undefined as its state value, and is primarily useful for cases like reading initial state from localStorage.
This may also be a "lazy initializer" function, which should return an initial state value when called. In Redux-Toolkit, the createSlice method helps us create a slice of that redux-store, which contains the reducer and actions in a single file. The initial state value for this slice of state.
