Example of Calendar with Events Listed in React Native

React Native Calendar with Events

This is an Example of Calendar with Events Listed in React Native. To make a Calendar with Events in React Native we have a EventCalendar component provided by react-native-events-calendar.

In this example, you can add the events in a calendar using an event array. You just need to pass the date and time (or some other elements if you want) of the event as a JSON array and this will show you all the events on the calendar. You can use click on the calendar event to get further details of the event.

If you want to add the event in your device’s calendar also then you can also see Add Event in Device’s Calendar from React Native App for Android and iOS

How to use EventCalendar Component?

<EventCalendar
  eventTapped={this.eventClicked.bind(this)}
  // Function on event press
  events={this.state.events}
  // passing the Array of event
  width={width}
  // Container width
  size={60}
  // Number of date will render before and after initDate 
  // (default is 30 will render 30 day before initDate 
  // and 29 day after initDate)
  initDate={'2019-01-01'}
  // Show initial date (default is today)
  scrollToFirst
  // Scroll to first event of the day (default true)
/>

In this example of Calendar with Events, we will make a calendar with some event listed from a dummy event array. If you want you can use web-services to fetch the data as an array from the server and pass that array in events prop of  EventCalendar. 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 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

npm install -g react-native-cli

Run the following commands to create a new React Native project

react-native init ProjectName

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

react-native init ProjectName --version X.XX.X
react-native init ProjectName --version react-native@next

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

Installation of Dependency

To use EventCalendar component you need to install react-native-events-calendar package.

To install this Open the terminal and jump into your project

cd ProjectName

Run the following command

npm install react-native-events-calendar --save

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

Code

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

App.js

// Example of Calendar with Events Listed in React Native
// https://aboutreact.com/example-of-calendar-with-events-listed-in-react-native/

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

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

//import EventCalendar component
import EventCalendar from 'react-native-events-calendar';

//get the size of device
let {width} = Dimensions.get('window');

const App = () => {
  const [events, setEvents] = useState([
    {
      start: '2020-01-01 00:00:00',
      end: '2020-01-01 02:00:00',
      title: 'New Year Party',
      summary: 'xyz Location',
    },
    {
      start: '2020-01-01 01:00:00',
      end: '2020-01-01 02:00:00',
      title: 'New Year Wishes',
      summary: 'Call to every one',
    },
    {
      start: '2020-01-02 00:30:00',
      end: '2020-01-02 01:30:00',
      title: 'Parag Birthday Party',
      summary: 'Call him',
    },
    {
      start: '2020-01-03 01:30:00',
      end: '2020-01-03 02:20:00',
      title: 'My Birthday Party',
      summary: 'Lets Enjoy',
    },
    {
      start: '2020-02-04 04:10:00',
      end: '2020-02-04 04:40:00',
      title: 'Engg Expo 2020',
      summary: 'Expoo Vanue not confirm',
    },
  ]);

  const eventClicked = (event) => {
    //On Click of event showing alert from here
    alert(JSON.stringify(event));
  };

  return (
    <SafeAreaView style={styles.container}>
      <View style={styles.container}>
        <EventCalendar
          eventTapped={eventClicked}
          // Function on event press
          events={events}
          // Passing the Array of event
          width={width}
          // Container width
          size={60}
          // number of date will render before and after initDate
          // (default is 30 will render 30 day before initDate
          // and 29 day after initDate)
          initDate={'2020-01-01'}
          // Show initial date (default is today)
          scrollToFirst
          // Scroll to first event of the day (default true)
        />
      </View>
    </SafeAreaView>
  );
};
export default App;

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
  },
});

To Run the React Native App

Open the terminal again and jump into your project using.

cd ProjectName

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

react-native run-android

or on the iOS Simulator by running (macOS only)

react-native run-ios
