In this guide, I will walk you through the process step by step. Please make sure you have Node.js, npm (Node Package Manager), and Expo CLI installed on your system.

1. Prerequisites
Before you start, make sure you have the following tools installed:
- Node.js and npm (You can download them from the official website)
- Expo CLI (Install it using
npm install -g expo-cli
)
2. Creating a New React Native Expo Project
First, create a new Expo project if you haven't already:
expo init MyReduxApp
cd MyReduxApp
Follow the instructions to set up your project, and then navigate to your project directory:
cd MyReduxApp
3. Installing Redux Toolkit and Thunk
Install Redux Toolkit and Thunk in your project:
npm install @reduxjs/toolkit react-redux redux-thunk
4. Setting Up Redux Store
Create a folder called store
in your project directory to organize your Redux-related files. Inside the store
folder, create a file called store.js
:
// store.js
import { configureStore } from '@reduxjs/toolkit';
import rootReducer from './reducers'; // Create this file in the next section
import thunk from 'redux-thunk';
const store = configureStore({
reducer: rootReducer,
middleware: (getDefaultMiddleware) => getDefaultMiddleware().concat(thunk),
});
export default store;
5. Creating Actions and Reducers
In the store
folder, create a file called reducers.js
. This is where you'll define your reducers using Redux Toolkit:
// reducers.js
import { combineReducers } from 'redux';
import { createSlice } from '@reduxjs/toolkit';
const initialState = {
// Define your initial state here
};
const mySlice = createSlice({
name: 'myData',
initialState,
reducers: {
// Define your actions and reducers here
},
});
const rootReducer = combineReducers({
myData: mySlice.reducer,
// Add more slices as needed
});
export default rootReducer;
Define your actions and reducers inside the mySlice
slice, and feel free to create more slices as needed for different parts of your application.
6. Connecting Redux to Your Components
You'll need to use the react-redux
library to connect your components to the Redux store. Let's assume you have a component named MyComponent
that should access your Redux state. Here's how to do it:
// MyComponent.js
import React from 'react';
import { useSelector, useDispatch } from 'react-redux';
import { someAction } from './store/reducers'; // Import your actions
const MyComponent = () => {
const myData = useSelector((state) => state.myData);
const dispatch = useDispatch();
return (
<div>
<p>{myData.someValue}</p>
<button onClick={() => dispatch(someAction())}>Dispatch Action</button>
</div>
);
};
export default MyComponent;
7. Thunk Middleware for Asynchronous Actions
You can use Thunk middleware to handle asynchronous actions. For example, you can create an async action like this:
// store/reducers.js
import { createAsyncThunk } from '@reduxjs/toolkit';
export const fetchData = createAsyncThunk('myData/fetchData', async (payload, { dispatch, getState }) => {
try {
const response = await fetch('https://api.example.com/data');
const data = await response.json();
dispatch(setData(data));
} catch (error) {
console.error('Error fetching data:', error);
}
});
8. Testing Your Redux Setup
Run your application with Expo to test your Redux setup:
expo start
9. Building and Running Your App
Once you're satisfied with your app and want to create a production build, you can use Expo to build and deploy it.
Building the app:
expo build:android
# or
expo build:ios
This command will generate APK (for Android) or IPA (for iOS) files that you can use to install and distribute your app.
That's it! You've successfully set up a React Native Expo project with Redux Toolkit and Thunk for state management and asynchronous actions. You can now build and expand your application with powerful state management capabilities.
