React Native Programming Fundamentals

React Native is a popular open-source framework used for building mobile applications using the ReactJS library. React Native allows developers to build native mobile apps for iOS and Android platforms using a single codebase written in JavaScript. In this article, we will explore the fundamental concepts of React Native programming, along with detailed examples.

Components:

Components are the building blocks of React Native apps. They are reusable pieces of code that can be used to build the user interface of an app. In React Native, there are two types of components: functional components and class components. Functional components are used for simple UI components, while class components are used for more complex UI components that require state management.
Example:

				
					
import React from 'react';
import { View, Text } from 'react-native';

const App = () => {
  return (
    <View><Text>Hello, World!</Text></View>
  );
};

export default App;
				
			

Props:

Props are short for properties and are used to pass data between components in React Native. Props are read-only, meaning that they cannot be changed by the component that receives them. Props can be passed down to child components using the curly braces syntax.
Example:

				
					
import React from 'react';
import { View, Text } from 'react-native';

const App = () => {
  return (
    <View><Greeting name="John" /></View>
  );
};

const Greeting = (props) => {
  return (
    <Text>Hello, {props.name}!</Text>
  );
};

export default App;
				
			

State:

State is used for managing dynamic data in React Native. Unlike props, state is mutable, meaning that it can be changed by the component that owns it. To change the state of a component, we use the setState method. Example:

				
					
import React, { useState } from 'react';
import { View, Text, Button } from 'react-native';

const App = () => {
  const [count, setCount] = useState(0);

  const handleIncrement = () => {
    setCount(count + 1);
  };

  return (
    <View><Text>You clicked {count} times</Text><Button title="Click me" onPress={handleIncrement} /></View>
  );
};

export default App;
				
			

Styling:

Styling: Styling in React Native is done using JavaScript, rather than CSS. React Native provides a set of built-in styles that can be used to style components, along with the ability to create custom styles using the StyleSheet API.

				
					
import React from 'react';
import { View, Text, StyleSheet } from 'react-native';

const App = () => {
  return (
    <View style={styles.container}><Text style={styles.text}>Hello, World!</Text></View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
    backgroundColor: '#fff',
  },
  text: {
    fontSize: 20,
    fontWeight: 'bold',
    color: '#333',
  },
});

export default App;
				
			

Navigation

Navigation is used to move between screens in a React Native app. React Navigation is a popular library used for navigation in React Native. It provides a set of navigators that can be used to navigate between screens, along with a set of customizable components for building navigation UI.
Example:
				
					
import React from 'react';
import { View, Text, Button } from 'react-native';
import { createStackNavigator } from '@react-navigation/stack';
import { NavigationContainer } from '@React Navigation';
const HomeScreen = ({ navigation }) => {
return (
<View>
<Text>Welcome to the home screen!</Text>
<Button
title="Go to Details"
onPress={() => navigation.navigate('Details')}
/>
</View>
);
};
const DetailsScreen = () => {
return (
<View>
<Text>Welcome to the details screen!</Text>
</View>
);
};
const Stack = createStackNavigator();
const App = () => {
return (
<NavigationContainer>
<Stack.Navigator>
<Stack.Screen name="Home" component={HomeScreen} />
<Stack.Screen name="Details" component={DetailsScreen} />
</Stack.Navigator>
</NavigationContainer>
);
};
				
			
In conclusion, these are just a few of the fundamental concepts of React Native programming. React Native is a powerful framework that allows developers to build mobile applications using familiar web development tools and technologies. With the examples above, you should have a better understanding of how React Native works and how to get started building your own mobile applications.

Simple React Native Application

here’s a detailed tutorial on how to create a React Native application that interacts with an external REST API to create, update, and retrieve articles. We will also cover deployment using Expo and AWS Amplify.

Prerequisites

Before we get started, we need to make sure we have the following installed:
  • Node.js and npm (Node.js version 10 or later)
  • React Native CLI
  • Expo CLI
  • An account with Expo and AWS Amplify

Step 1: Setting up the Development Environment

  1. Open a terminal window and create a new React Native project using the following command:
				
					
npx react-native init MyProject
				
			
Change to the project directory:
Example:
				
					

cd MyProject
				
			
Install the necessary dependencies:
				
					
npm install axios react-native-elements
				
			
  • axios: A promise-based HTTP client for making API requests.
  • react-native-elements: A UI library for React Native that provides pre-built components.

Step 2: Creating the Article Component

  1. Create a new folder called components in the root directory of our project.
  2. Create a new file called Article.js in the components folder.
  3. Add the following code to the Article.js file:
				
					

import React, { useState, useEffect } from 'react';
import { View, Text, TextInput, Button } from 'react-native';
import axios from 'axios';

const Article = () => {
  const [title, setTitle] = useState('');
  const [content, setContent] = useState('');
  const [articles, setArticles] = useState([]);

  const fetchArticles = async () => {
    const response = await axios.get('https://my-api-url.com/articles');
    setArticles(response.data);
  };

  useEffect(() => {
    fetchArticles();
  }, []);

  const handleSave = async () => {
    await axios.post('https://my-api-url.com/articles', { title, content });
    setTitle('');
    setContent('');
    fetchArticles();
  };

  const handleDelete = async (id) => {
    await axios.delete(`https://my-api-url.com/articles/${id}`);
    fetchArticles();
  };

  return (
    <View><Text>Articles</Text><TextInputvalue={title}onChangeText={(text) => setTitle(text)}
        placeholder="Title"
      />
      <TextInputvalue={content}onChangeText={(text) => setContent(text)}
        placeholder="Content"
      />
      <Button title="Save" onPress={handleSave} />
      {articles.map((article) => (
        <View key={article.id}><Text>{article.title}</Text><Text>{article.content}</Text><Buttontitle="Delete"onPress={() => handleDelete(article.id)}
          />
        </View>
      ))}
    </View>
  );
};

export default Article;
				
			
  1. In this code, we have created a state for the article title and content. We have also created a state for the list of articles retrieved from the REST API.
  2. We are using the useEffect hook to fetch the articles from the REST API when the component mounts.
  3. We have also created two functions, handleSave and handleDelete, to create and delete articles in the REST API.
  4. Finally, we are rendering a list of articles with their titles, content, and a delete button for each.

Step 3: Running the App

Open a terminal window and start the development server:
				
					
npx react-native start
				
			
Open a new terminal window and run the app on an Android or iOS simulator or device:
				
					javaCopy code
npx react-native run-android
				
			

or

				
					javaCopy code
npx react-native run-ios
				
			
Note: You may need to install additional dependencies or configure your environment to run on a simulator or device.
  • The app should now open on your simulator or device, displaying a form to create articles and a list of articles retrieved from the REST API.

Step 4: Deployment using Expo

Install the Expo CLI globally:
				
					
npm install -g expo-cli
				
			
Create a new Expo account and login using the Expo CLI:
				
					Copy code
expo login
				
			
Publish the app to Expo:
				
					
expo publish
				
			
  1. This will generate a URL that can be used to access the app on the Expo website.
  2. Download the Expo app on your mobile device.
  3. Open the Expo app and scan the QR code generated in the terminal or visit the URL provided by Expo to access the app.
  4. Note: Make sure your device and development computer are on the same network.

Step 5: Deployment using AWS Amplify

  1. Create a new Amplify app on the AWS console.
  2. Install the Amplify CLI:
				
					
npm install -g @aws-amplify/cli
				
			
Initialize Amplify in your project directory:
				
					
amplify init
				
			
  1. Follow the prompts to configure your app and create a new environment.
  2. Create a new API using Amplify:
				
					
amplify add api
				
			
  1. Follow the prompts to create a new REST API and configure the authorization and authentication settings.
  2. Push the changes to the Amplify app:
				
					
amplify push
				
			
  1. This will deploy your app to the configured environment on AWS.
  2. Update the REST API endpoint in the Article.js file to use the endpoint generated by Amplify.
  3. Restart the development server and run the app on your simulator or device.
  4. The app should now be able to create, update, and retrieve articles using the REST API deployed on AWS Amplify.


Conclusion:

In this tutorial, we have covered the steps to create a React Native app that interacts with a REST API to create, update, and retrieve articles. We have also covered deployment using Expo and AWS Amplify. With this knowledge, you should be able to create similar applications that interact with external APIs to build powerful mobile applications.
