Coding react native

If you’ve ever developed a large-scale application using React Native, you’ve likely encountered the challenge of state management. It’s a common issue that can become increasingly complex as your application grows. In this article, we’ll explore how to solve this problem using Redux, a predictable state container for JavaScript apps.

Understanding State Management

State management is a crucial aspect of any application. It involves maintaining the state, or data, of an application and how it changes over time. As your application grows, managing state can become increasingly complex. This is where Redux comes into play.

Introduction to Redux

Redux is a library that helps manage application state. It follows three basic principles:

  1. Single source of truth: The state of your whole application is stored in an object tree within a single store.
  2. State is read-only: The only way to change the state is to emit an action, an object describing what happened.
  3. Changes are made with pure functions: To specify how the state tree is transformed by actions, you write pure reducers.

Setting Up the Environment

To get started, we need to set up a new React Native project. Once you’ve done that, you can install Redux using the following command:

npm install redux react-redux

Implementing Redux in React Native

In Redux, we define actions and reducers. Actions are JavaScript objects that have a type property, describing the type of action being performed, and payload property, describing what is being updated. Reducers are functions that decide how the application’s state changes in response to actions sent to the store.

Here’s an example of how to connect a React Native component to the Redux store:

import { connect } from 'react-redux';

// Your component here

const mapStateToProps = state => ({
// Your state here

export default connect(mapStateToProps)(YourComponent);

Example: Building a Simple App

Let’s build a simple counter app using React Native and Redux. We’ll start by defining our actions:

// actions.js
export const increment = () => ({
type: 'INCREMENT',

export const decrement = () => ({
type: 'DECREMENT',

Next, we’ll define our reducer:

// reducer.js
const counter = (state = 0, action) => {
switch (action.type) {
return state + 1;
return state - 1;
return state;

export default counter;

Finally, we’ll connect our component to the Redux store:

// Counter.js
import React from 'react';
import { connect } from 'react-redux';
import { increment, decrement } from './actions';

const Counter = ({ count, increment, decrement }) => (
// Your component here

const mapStateToProps = state => ({
count: state,

const mapDispatchToProps = dispatch => ({
increment: () => dispatch(increment()),
decrement: () => dispatch(decrement()),

export default connect(mapStateToProps, mapDispatchToProps)(Counter);


State management is a common challenge in React Native development, but with Redux, we can manage our application’s state in a predictable way. By following the principles of Redux and connecting our components to the Redux store, we can build large-scale applications more efficiently.
