To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react native command line interface to make our React Native App.

If you have previously installed a global react-native-cli package, please remove it as it may cause unexpected issues:

npm uninstall -g react-native-cli @react-native-community/cli

Run the following commands to create a new React Native project

npx react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

npx react-native init ProjectName --version X.XX.X

Note If the above command is failing, you may have old version of react-native or react-native-cli installed globally on your pc. Try uninstalling the cli and run the cli using npx.

This will make a project structure with an index file named App.js in your project directory.

Code

Open App.js in any code editor and replace the code with the following code

App.js

// React Native Toast – Toast Alert for Android
// https://aboutreact.com/react-native-toast-android-only/

// import React in our code
import React from 'react';

// import all the components we are going to use
import {
  SafeAreaView,
  View,
  Text,
  ToastAndroid,
  TouchableHighlight,
  StyleSheet,
} from 'react-native';

const App = () => {
  const toastWithDurationHandler = () => {
    // To make Toast with duration
    ToastAndroid.show(
      'Hi I am Simple Toast', ToastAndroid.SHORT
    );
  };

  const toastWithDurationGravityHandler = () => {
    // To make Toast with
    // * Duration
    // * Gravity
    ToastAndroid.showWithGravity(
      'Hi I am Toast with center gravity',
      ToastAndroid.SHORT, //can be SHORT, LONG
      ToastAndroid.CENTER, //can be TOP, BOTTON, CENTER
    );
  };

  const toastWithDurationGravityOffsetHandler = () => {
    // To make Toast With
    // * Duration
    // * Gravity
    // * Offset
    ToastAndroid.showWithGravityAndOffset(
      'Hi I am Toast with garavity and offset',
      ToastAndroid.LONG, //can be SHORT, LONG
      ToastAndroid.BOTTOM, //can be TOP, BOTTON, CENTER
      25, //xOffset
      500, //yOffset
    );
  };

  return (
    <SafeAreaView style={styles.container}>
      <View style={styles.container}>
        <Text style={styles.titleStyle}>
          React Native Toast – Toast Alert for Android
        </Text>
        {/*To generate Toast With Duration*/}
        <TouchableHighlight
          style={styles.buttonStyle}
          onPress={toastWithDurationHandler}>
          <Text style={styles.buttonTextStyle}>
            Generate Toast With Duration
          </Text>
        </TouchableHighlight>

        {/*To generate Toast With Duration And Gravity*/}
        <TouchableHighlight
          style={styles.buttonStyle}
          onPress={toastWithDurationGravityHandler}>
          <Text style={styles.buttonTextStyle}>
            Generate Toast With Duration AND Gravity
          </Text>
        </TouchableHighlight>

        {/*To generate Toast With Duration, Gravity And Offset*/}
        <TouchableHighlight
          style={styles.buttonStyle}
          onPress={toastWithDurationGravityOffsetHandler}>
          <Text style={styles.buttonTextStyle}>
            Generate Toast With Duration, Gravity And Offset
          </Text>
        </TouchableHighlight>
      </View>
    </SafeAreaView>
  );
};
export default App;

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
    backgroundColor: '#307ecc',
    padding: 16,
  },
  buttonStyle: {
    minWidth: '100%',
    padding: 10,
    backgroundColor: '#f5821f',
    margin: 15,
  },
  buttonTextStyle: {
    color: 'white',
    textAlign: 'center',
  },
  titleStyle: {
    color: 'white',
    textAlign: 'center',
    fontSize: 20,
    marginTop: 10,
  },
});

To Run the React Native App

Open the terminal again and jump into your project using.

cd ProjectName

1. Start Metro Bundler

First, you will need to start Metro, the JavaScript bundler that ships with React Native. To start Metro bundler run following command

npx react-native start

Once you start Metro Bundler it will run forever on your terminal until you close it. Let Metro Bundler run in its own terminal. Open a new terminal and run the application.

2. Start React Native Application

To run the project on an Android Virtual Device or on real debugging device

npx react-native run-android

or on the iOS Simulator by running (macOS only)

npx react-native run-ios
