React Native Calendar Picker using react-native-calendar-picker

React Native Calendar Picker

This is an Example Showing the Working of Calendar Picker in React Native. Calendar Picker can be used to select the date range (Start Date to End Date). For the Calendar Picker that can be used on both platforms, you need to use a react-native-calendar-picker library.  A single React Native Calendar Picker component for both Android and IOS.

In this example, We will make a Calendar Picker which will have the feature to select a date range and will show the starting and ending date on a Text. So let’s get started.

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.

Installation of Dependencies

To use CalendarPicker you need to install react-native-calendar-picker package.

To install this open the terminal and jump into your project using

cd ProjectName

Run the following commands

npm install react-native-calendar-picker --save

npm install moment --save

This command will copy all the dependencies into your node_module directory. –save is optional, it is just to update the react-native-calendar-picker dependency in your package.json file.

Code for Calendar Picker

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

App.js

// React Native Calendar Picker using react-native-calendar-picker
// https://aboutreact.com/react-native-calendar-picker/

// import React in our code
import React, {useState} from 'react';

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

//import CalendarPicker from the package we installed
import CalendarPicker from 'react-native-calendar-picker';

const App = () => {
  const [selectedStartDate, setSelectedStartDate] = useState(null);
  const [selectedEndDate, setSelectedEndDate] = useState(null);

  const onDateChange = (date, type) => {
    //function to handle the date change
    if (type === 'END_DATE') {
      setSelectedEndDate(date);
    } else {
      setSelectedEndDate(null);
      setSelectedStartDate(date);
    }
  };

  return (
    <SafeAreaView style={styles.container}>
      <View style={styles.container}>
        <Text style={styles.titleStyle}>
          React Native Calendar Picker
        </Text>
        <CalendarPicker
          startFromMonday={true}
          allowRangeSelection={true}
          minDate={new Date(2018, 1, 1)}
          maxDate={new Date(2050, 6, 3)}
          weekdays={
            [
              'Mon', 
              'Tue', 
              'Wed', 
              'Thur', 
              'Fri', 
              'Sat', 
              'Sun'
            ]}
          months={[
            'January',
            'Febraury',
            'March',
            'April',
            'May',
            'June',
            'July',
            'August',
            'September',
            'October',
            'November',
            'December',
          ]}
          previousTitle="Previous"
          nextTitle="Next"
          todayBackgroundColor="#e6ffe6"
          selectedDayColor="#66ff33"
          selectedDayTextColor="#000000"
          scaleFactor={375}
          textStyle={{
            fontFamily: 'Cochin',
            color: '#000000',
          }}
          onDateChange={onDateChange}
        />
        <View style={styles.textStyle}>
          <Text style={styles.textStyle}>
            Selected Start Date :
          </Text>
          <Text style={styles.textStyle}>
            {selectedStartDate ? selectedStartDate.toString() : ''}
          </Text>
          <Text style={styles.textStyle}>
            Selected End Date :
          </Text>
          <Text style={styles.textStyle}>
            {selectedEndDate ? selectedEndDate.toString() : ''}
          </Text>
        </View>
      </View>
    </SafeAreaView>
  );
};
export default App;

const styles = StyleSheet.create({
  container: {
    flex: 1,
    paddingTop: 30,
    backgroundColor: '#ffffff',
    padding: 16,
  },
  textStyle: {
    marginTop: 10,
  },
  titleStyle: {
    textAlign: 'center',
    fontSize: 20,
    margin: 20,
  },
});

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
