npm install @reduxjs/toolkit react-reduxOnce it’s installed, you’re ready for the next step! Redux Toolkit works with Next.js 13 without any extra tools. It’s simple and saves time. There is no complex setup, just easy commands and smooth sailing.
How to configure the Redux store in Next.js 13 using Redux Toolkit
After installing it’s time to build your store. Create a new file named store.js in your project directory. Put this code there:
import { configureStore } from '@reduxjs/toolkit';
import counterReducer from './features/counterSlice';
export const store = configureStore({
reducer: {
counter: counterReducer,
},
});Then, proceed to your pages/_app.js file and encapsulate your app with a Provider like so:
import { Provider } from 'react-redux';
import { store } from '../store';
function MyApp({ Component, pageProps }) {
return (
<Provider store={store}>
<Component {...pageProps} />
</Provider>
);
}
export default MyApp;Now your shop is ready. You can control your app’s state with ease from here.
Making Slices with Redux Toolkit in Next.js 13
Making slices is really simple and easy with the Redux Toolkit in Next.js 13. Think of a slice as a small part of your app’s state. Each slice controls a specific piece of data.
How to create a slice using Redux Toolkit in Next.js 13
To create a slice you need to make a new file. Let’s call it counterSlice.js and put it inside a folder named features. Now, here’s the simple code you can use:
import { createSlice } from '@reduxjs/toolkit';
export const counterSlice = createSlice({
name: 'counter',
initialState: {
value: 0,
},
reducers: {
increment: (state) => {
state.value += 1;
},
decrement: (state) => {
state.value -= 1;
},
reset: (state) => {
state.value = 0;
},
},
});
export const { increment, decrement, reset } = counterSlice.actions;
export default counterSlice.reducer;This code creates a simple counter. You can now increase, decrease, or reset your number. It’s easy and straightforward and works great in your app.
How to manage actions and reducers in Redux Toolkit for Next.js 13
Actions and reducers help you control what happens to your app’s data. In Redux Toolkit, they are super easy to use. Actions are like buttons—when you click one, something happens! Reducers determine how the state will alter.
Once you’ve got your slice, Redux Toolkit does the actions for you. In our example, we’ve got increment, decrement, and reset. You can use those actions anywhere in your app by calling them through React Redux’s useDispatch hook.
import { useDispatch } from 'react-redux';
import { increment } from '../features/counterSlice';
const CounterButton = () => {
const dispatch = useDispatch();
return (
<button onClick={() => dispatch(increment())}>
Increase Counter
</button>
);
};That’s it! Your app is now able to update its data with a click of a button. Simple, quick, and smooth!
Handling Async Logic with Redux Toolkit in Next.js 13
Sometimes, you need to get data from an API or a server. This is called async logic because it happens in the background. With the Redux Toolkit in Next.js 13, you can easily handle async tasks using thunks.
How to create and use async thunks in Redux Toolkit for Next.js 13
Async thunks help you fetch data or do actions that take time. Redux Toolkit has a tool called createAsyncThunk. It makes everything simple! Let’s create a thunk that fetches user data from an API.
Here’s an example:
import { createAsyncThunk } from '@reduxjs/toolkit';
export const fetchUser = createAsyncThunk(
'user/fetchUser',
async (userId) => {
const response = await fetch(`https://jsonplaceholder.typicode.com/users/${userId}`);
const data = await response.json();
return data;
}
);This code fetches user data based on the user’s ID. When the data comes back, you can use this thunk inside your slice to update your state.
How to handle loading and error states using Redux Toolkit in Next.js 13
When you load data, you have to know if it’s still loading or if there was an error. Redux Toolkit assists you with that in a clean way.
Within your slice, you might include additional reducers to manage the three states: pending (in progress), fulfilled (success), and rejected (failure).
Example:
import { createSlice } from '@reduxjs/toolkit';
import { fetchUser } from './userThunks';
const userSlice = createSlice({
name: 'user',
initialState: {
user: null,
loading: false,
error: null,
},
extraReducers: (builder) => {
builder
.addCase(fetchUser.pending, (state) => {
state.loading = true;
state.error = null;
})
.addCase(fetchUser.fulfilled, (state, action) => {
state.loading = false;
state.user = action.payload;
})
.addCase(fetchUser.rejected, (state, action) => {
state.loading = false;
state.error = action.error.message;
});
},
});
export default userSlice.reducer;Now your app knows it’s loading and if something went wrong. That helps you to show a loading spinner or error message in your app.
Best Practices on Using Redux Toolkit in Next.js 13
By adhering to best practices, your app is fast, clean, and a joy to work with. When you’re working with the Redux Toolkit using Next.js 13, it’s best to remain organized and avoid common mistakes. Let’s explore how you can do that!
How to structure Redux Toolkit files for large Next.js 13 applications
As your project expands, it’s important to remain organized. If your directories are disorganized, it’s difficult to locate things or patch bugs. A sound method of being well-organized is to employ a reasonable folder structure.
For instance: features folder for each feature, like user or posts Inside each folder, keep these files:slice.js (or slice. ts if using TypeScript)thunks.js for as ync actionsselectors.js to get data from the state
Here’s a simple example of a structure:
src/
app/
store.js
features/
user/
slice.js
thunks.js
selectors.js
posts/
slice.js
thunks.js
selectors.jsThis setup helps you and your team work faster because everything is in the right place. It also keeps your code clean and easy to understand.
Common mistakes to avoid when using Redux Toolkit in Next.js 13
Even though Redux Toolkit makes things easier, there are still mistakes people make. Here are some to watch out for:
Not using createSlice – Some people still write reducers by hand. createSlice saves time and reduces mistakes.
Forgetting immer – Redux Toolkit uses simmer under the hood, so you can safely write code that “mutates” state. You don’t need to copy the state manually.
Overusing Redux – Not every piece of state needs Redux! Use Redux for global state and React state (state) for local things like a modal.
Not handling loading and error states – Always show users when things are loading or if something went wrong.
Putting too much logic inside reducers – Keep reducers simple. Use thunks for complex logic or API calls.
