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 init to make our React Native App.
Assuming that you have node installed, you can use npm to install the react-native-cli command line utility.
Open the terminal and go to the workspace and run
Run the following commands to create a new React Native projectnpm install -g react-native-cli
This will make a project structure with an index file named App.js in your project directory.react-native init ProjectName
Open App.js in any code editor and the Replace the code with the following code.
App.js
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 | //This is an example code to understand Slider// import React, { Component } from 'react'; //import react in our code. import {Slider,View, Text, StyleSheet } from 'react-native'; //import all the components we are going to use. export default class App extends Component { constructor(props) { super(props); this.state = { //Initial Value of slider sliderValue: '15' }; } render() { return ( <View style={styles.container}> {/*Text to show slider value*/} <Text style={{color: 'black'}}>Value of slider is : {this.state.sliderValue}</Text> {/*Slider with max, min, step and initial value*/} <Slider maximumValue='100' minimumValue='0' step='1' value={this.state.sliderValue} onValueChange={(sliderValue) => this.setState({ sliderValue })} /> </View> ); } } const styles = StyleSheet.create({ container: { flex: 1, padding:20, justifyContent: 'center', backgroundColor: '#ecf0f1', } }); |
