How to Install Redux in React Native Apps

Introduction to What is Redux in React Native Apps

What is Redux and Why Use It in React Native?

Redux is a powerful React state management tool used in React Native applications. It offers a centralised store that allows components to access and update data. Redux facilitates efficient communication and consistent state management in complex apps by defining actions and reducers.

With Redux, React Native developers can simplify data flow and avoid the complexities of passing props between multiple components. The centralised store serves as a single source of truth for the application’s state, making it easily accessible and modifiable from any component. 

In this article, we will explore the implementation of React Native Redux applications, providing a deeper understanding of their benefits. 

Installation Process of Redux in React Native Apps

To install Redux in a React Native app, follow these steps:

  • Start by creating a new React Native project or navigate to your existing project directory.
  • Open a terminal or command prompt and navigate to the project directory.
  • Install the required dependencies by running the following command:

npm install redux react-redux

  • Additionally, if you plan to handle asynchronous actions with Redux, you can install redux-thunk as well:

npm install redux-thunk

  • Once the installation is complete, you can use Redux in your React Native app.


To set up Redux in your React Native app, follow these steps:


  • Create a new directory, usually named “store”, at the root level of your project. Inside the “store” directory, create a new file called “index.js“.
  • In the “index.js” file, import the necessary Redux modules:

import { createStore, applyMiddleware } from ‘redux’;

import thunk from ‘redux-thunk’;

import rootReducer from ‘./reducers’;

  • Create the Redux store by combining your reducers using the createStore function:

const store = createStore(rootReducer, applyMiddleware(thunk));

  • In your app’s entry point file (often “App.js” or “index.js“), import the necessary React Redux modules:

import { Provider } from ‘react-redux’;

import store from ‘./store’;

  • Wrap your main app component with the Provider component and pass the Redux store as a prop:

const App = () => {

  return (

    <Provider store={store}>

      {/* Your app component */}





export default App;


Redux is now set up in your React Native app!

Installing Required Packages and Dependencies

To install the necessary packages and dependencies for integrating Redux into your React Native app, follow these steps:

  • Step 1: Open a terminal or command prompt and navigate to your React Native project directory.
  • Step 2: Run the following command to install the required packages using npm:

npm install redux react-redux

Or, if you prefer using yarn, run:

yarn add redux react-redux

  • Step 3: Additionally, if you need to handle asynchronous actions in your Redux app, you can install redux-thunk by running:

npm install redux-thunk


yarn add redux-thunk

  • Step 4: Once the installation is complete, the necessary packages and dependencies are installed in your React Native project.

Creating a Redux Store

Now with all the dependencies installed, here’s how you can create a React Native Redux store: 

  • Import the ‘createStore’ from the Redux library and root reducer within a file.

import { createStore } from ‘redux’;

import rootReducer from ‘./reducers’;

  • Use ‘createStore’ function to pass the root reducer as an argument and create a Redux store. 

const store = createStore(rootReducer);


  • In the entry point file of your app, usually labelled as App.js or index.js, wrap the main app component along with ‘Provider’ component based in the ‘react-redux’ library. Pass the created store as a prop to Provider.


import React from ‘react’;

import ReactDOM from ‘react-dom’;

import { Provider } from ‘react-redux’;

import store from ‘./store’;

import App from ‘./App’;



  <Provider store={store}>

    <App />





The applied Provider component will make sure that all containing components have access to the Redux store.

Defining Actions and Reducers

Actions in Redux are plain JavaScript objects describing the change or event that should occur in the application. They are typically defined as constants and created using action creator functions.


For example – 


// Define action type

const ADD_TODO = ‘ADD_TODO’;


// Define action creator

const addTodo = (text) => {

  return {

    type: ADD_TODO,

    payload: {





In this example, ADD_TODO is the action type, and addTodo is the action creator function that returns the action object with the specified type and payload.

On the other hand, Reducers in Redux are functions that specify how the state should be updated based on the dispatched actions. They input the current state and the action and return a new state object. 


For example, 


// Define initial state

const initialState = {

  todos: [],



// Define reducer function

const todoReducer = (state = initialState, action) => {

  switch (action.type) {

    case ADD_TODO:

      return {


        todos: […state.todos, action.payload],



      return state;




In this example, ‘initialState’ represents the application’s initial state. In the case of “ADD_TODO,” it creates a new state object by adding the new todo item to the existing todos array. 

Connecting Redux to React Native Components

To connect Redux to React Native components, you can use the react-redux library, which provides bindings between Redux and React. Here’s a step-by-step guide on how to connect Redux to your React Native components:


  • Install the react-redux package:

npm install react-redux

  • Import necessary components from react-redux in your component file:

import { connect } from ‘react-redux’;

  • Define a mapStateToProps function:
  • This function maps the state from the Redux store to props that will be passed to your component.
  • It takes the state as an argument and returns an object with the desired props.


const mapStateToProps = (state) => {

  return {

    todos: state.todos,

    // other props mapping here




  • Define mapDispatchToProps function:
  • This function maps action creators to props, allowing your component to dispatch actions.
  • It takes the dispatch function as an argument and returns an object with the mapped action creators.


const mapDispatchToProps = (dispatch) => {

  return {

    addTodo: (text) => dispatch(addTodo(text)),

    // other action creators mapping here




  • Connect your component to Redux using the connect function:
  • Pass mapStateToProps and mapDispatchToProps as arguments to connect.
  • Wrap your component with the returned function.


const MyComponent = ({ todos, addTodo }) => {

  // component implementation here


export default connect(mapStateToProps,



  • Access the props in your component:
  • The mapped state from the Redux store (todos in this example) and the action creators (addTodo in this example) will be available as props in your component.

Implementing Redux Thunk Middleware

To implement Redux Thunk middleware in your Redux setup, follow these steps:


  • Install the required packages:

npm install redux-thunk

  • Import applyMiddleware and createStore from Redux, as well as redux-thunk:

import { createStore, applyMiddleware } from ‘redux’;

import thunk from ‘redux-thunk’;

  • Create your root reducer and initial state, similar to how you would go without middleware.
  • Apply the Redux Thunk middleware when creating the Redux store:

const store = createStore(rootReducer, applyMiddleware(thunk));

  • Define your action creator as a thunk function:


const fetchTodos = () => {

  return (dispatch) => {

    dispatch({ type: ‘FETCH_TODOS_REQUEST’ });


    // Perform asynchronous operations (e.g., API call)

    // Dispatch further actions based on the result


      .then((response) => response.json())

      .then((data) => {

        dispatch({ type: ‘FETCH_TODOS_SUCCESS’, payload: data });


      .catch((error) => {

        dispatch({ type: ‘FETCH_TODOS_FAILURE’, error: error.message });




  • Dispatch the thunk action from your component:
  • Import the action creator into your component.
  • Dispatch it using store.dispatch or the dispatch function available through connect.


import { useDispatch } from ‘react-redux’;

import { fetchTodos } from ‘../actions/todoActions’;


const MyComponent = () => {

  const dispatch = useDispatch();


  const handleFetchTodos = () => {




  // Rest of your component code



By implementing Redux Thunk middleware, you can write asynchronous action creators in Redux that can handle side effects and dispatch multiple actions over time. The Thunk middleware allows you to create more complex and powerful actions in your Redux application.

Debugging Redux in React Native Apps

Let’s explore some common approaches to help you debug your Redux in React Native :

  • Logging: Use console.log statements in your action creators, reducers, and components to log the state, action types, and other relevant data. This can provide insights into how the state changes and help identify any issues.
  • Redux DevTools Extension: Install the Redux DevTools extension in your browser (Chrome or Firefox) and configure it to work with your React Native app. It allows you to inspect and debug the state and actions in real-time, track changes, and even replay actions. 
  • Breakpoints and Debugging Tools: Use the debugging tools provided by your development environment, such as Chrome DevTools or React Native Debugger. Set breakpoints in your Redux-related code, step through the execution, and inspect variables and state to identify potential issues.
  • React Native Debugger: React Native Debugger is a standalone debugging tool specifically designed for React Native apps. It integrates with Redux DevTools and provides additional features for inspecting state, actions, and performance profiling.
