    Usage

    Scrollable CalendarStrip — New in 2.x

    The scrollable prop was introduced in 2.0.0 and features a bi-directional infinite scroller. It recycles days using RecyclerListView, shifting the dates as the ends are reached. The Chrome debugger can cause issues with this updating due to a RN setTimeout bug. To prevent date shifts at the ends of the scroller, set the minDate and maxDate range to a year or less.

    The refactor to support scrollable introduced internal changes to the CalendarDay component. Users of the dayComponent prop may need to adjust their custom day component to accommodate the props passed to it.

    import { View, StyleSheet } from 'react-native';
    import CalendarStrip from 'react-native-calendar-strip';
    
    const Example = () => (
      <View style={styles.container}>
        <CalendarStrip
          scrollable
          style={{height:200, paddingTop: 20, paddingBottom: 10}}
          calendarColor={'#3343CE'}
          calendarHeaderStyle={{color: 'white'}}
          dateNumberStyle={{color: 'white'}}
          dateNameStyle={{color: 'white'}}
          iconContainer={{flex: 0.1}}
        />
      </View>
    );
    
    const styles = StyleSheet.create({
      container: { flex: 1 }
    });
    

    Simple "out of the box" Example

    You can use this component without any styling or customization. Just import it in your project and render it:

    import { View, StyleSheet } from 'react-native';
    import CalendarStrip from 'react-native-calendar-strip';
    
    const Example = () => (
      <View style={styles.container}>
        <CalendarStrip
          style={{height:150, paddingTop: 20, paddingBottom: 10}}
        />
      </View>
    );
    
    const styles = StyleSheet.create({
      container: { flex: 1 }
    });
    

    Styling and animations Example

    Even though this component works withouth any customization, it is possible to customize almost everything, so you can make it as beautiful as you want:

    import React, {Component} from 'react';
    import {
        AppRegistry,
        View
    } from 'react-native';
    import moment from 'moment';
    
    import CalendarStrip from 'react-native-calendar-strip';
    
    class Example extends Component {
        let datesWhitelist = [{
          start: moment(),
          end: moment().add(3, 'days')  // total 4 days enabled
        }];
        let datesBlacklist = [ moment().add(1, 'days') ]; // 1 day disabled
    
        render() {
            return (
                <View>
                    <CalendarStrip
                        calendarAnimation={{type: 'sequence', duration: 30}}
                        daySelectionAnimation={{type: 'border', duration: 200, borderWidth: 1, borderHighlightColor: 'white'}}
                        style={{height: 100, paddingTop: 20, paddingBottom: 10}}
                        calendarHeaderStyle={{color: 'white'}}
                        calendarColor={'#7743CE'}
                        dateNumberStyle={{color: 'white'}}
                        dateNameStyle={{color: 'white'}}
                        highlightDateNumberStyle={{color: 'yellow'}}
                        highlightDateNameStyle={{color: 'yellow'}}
                        disabledDateNameStyle={{color: 'grey'}}
                        disabledDateNumberStyle={{color: 'grey'}}
                        datesWhitelist={datesWhitelist}
                        datesBlacklist={datesBlacklist}
                        iconLeft={require('./img/left-arrow.png')}
                        iconRight={require('./img/right-arrow.png')}
                        iconContainer={{flex: 0.1}}
                    />
                </View>
            );
        }
    }
    
    AppRegistry.registerComponent('Example', () => Example);

    customDatesStyles

    Custom date styling example

    This prop may be passed an array of style objects or a callback which receives a date param and returns a style object for it. The format for the style object follows:

    Key Description Type optional
    startDate anything parseable by Moment. Any False (unused w/ callback)
    endDate specify a range. If no endDate is supplied, startDate is treated as a single date. Any True (unused w/ callback)
    dateNameStyle Text style for the name of the day. Any True
    dateNumberStyle Text style for the number of the day. Any True
    highlightDateNameStyle Text style for the selected name of the day. This overrides the global prop. Any True
    highlightDateNumberStyle Text style for the selected number of the day. This overrides the global prop. Any True
    dateContainerStyle Style for the date Container. Any True
    Array Usage Example:
      let customDatesStyles = [];
      let startDate = moment();
      for (let i=0; i<6; i++) {
        customDatesStyles.push({
            startDate: startDate.clone().add(i, 'days'), // Single date since no endDate provided
            dateNameStyle: styles.dateNameStyle,
            dateNumberStyle: styles.dateNumberStyle,
            // Random color...
            dateContainerStyle: { backgroundColor: `#${(`#00000${(Math.random() * (1 << 24) | 0).toString(16)}`).slice(-6)}` },
          });
      }
    
      render() {
        return (
          <CalendarStrip
            customDatesStyles={customDatesStyles}
            ...
          />
        );
      }
    
    Callback Usage Example:
      const customDatesStylesFunc = date => {
        if (date.isoWeekday() === 5) { // Fridays
          return {
            dateNameStyle: {color: 'blue'},
            dateNumberStyle: {color: 'purple'},
            dateContainerStyle:  {color: 'yellow'},

    dayComponentHeight Fixed height for the CalendarDay component or custom dayComponent. Number

    Icon Sizing

    Prop Description Type Default
    iconLeft Icon to be used for the left icon. It accepts require statement with url to the image (require('./img/icon.png')), or object with remote uri {uri: 'http://example.com/image.png'} Any
    iconRight Icon to be used for the right icon. It accepts require statement with url to the image (require('./img/icon.png')), or object with remote uri {uri: 'http://example.com/image.png'} Any
    iconStyle Style that is applied to both left and right icons. It is applied before iconLeftStyle or iconRightStyle. Any
    iconLeftStyle Style for left icon. It will override all of the other styles applied to icons. Any
    iconRightStyle Style for right icon. It will override all of the other styles applied to icons. Any
    iconContainer Style for the container of icons. (Example usage is to add flex property to it so in the portrait mode, it will shrink the dates strip) Any
    leftSelector Component for the left selector control. May be an instance of any React component. This overrides the icon* props above. Passing in an empty array [] hides this control. Any
    rightSelector Component for the right selector control. May be an instance of any React component. This overrides the icon* props above. Passing in an empty array [] hides this control. Any

    Custom Day component

    Prop Description Type Default
    dayComponent User-defined component for the Days. All day-related props are passed to the custom component: https://github.com/BugiDev/react-native-calendar-strip/blob/master/src/CalendarStrip.js#L542 Any

    Methods

    Methods may be accessed through the instantiated component's ref.

    Prop Description
    getSelectedDate() Returns the currently selected date. If no date is selected, returns undefined.
    setSelectedDate(date) Sets the selected date. date may be a Moment object, ISO8601 date string, or any format that Moment is able to parse. It is the responsibility of the caller to select a date that makes sense (e.g. within the current week view). Passing in a value of 0 effectively clears the selected date. scrollToOnSetSelectedDate controls whether the scroller repositions to the selected date.
    getNextWeek() Advance to the next week.
    getPreviousWeek() Rewind to the previous week.
    updateWeekView(date) Show the week starting on date.

    name The name of the locale (ex. 'fr') String
    config The config object holding all of the localization strings.. Object

    Build Release info

    To properly make a release build, import the appropriate "Locale" module using the following steps. Not importing the locale module will crash the release build (though the dev build will work).

    1- import momentJs module:

    $ yarn add moment

    or

    $ npm install moment

    2- Go to your index.js and import the specific "Locale" after the main moment import. Ex:

    import 'moment';
    import 'moment/locale/fr';  // language must match config
    import moment from 'moment-timezone';  // only if timezone is needed
    

    The locale import must match the language specified in the locale config (example below).

    Example of one locale object is:

    const locale = {
      name: 'fr',
      config: {
        months: 'Janvier_Février_Mars_Avril_Mai_Juin_Juillet_Août_Septembre_Octobre_Novembre_Décembre'.split(
          '_'
        ),
        monthsShort: 'Janv_Févr_Mars_Avr_Mai_Juin_Juil_Août_Sept_Oct_Nov_Déc'.split(
          '_'
        ),
        weekdays: 'Dimanche_Lundi_Mardi_Mercredi_Jeudi_Vendredi_Samedi'.split('_'),
        weekdaysShort: 'Dim_Lun_Mar_Mer_Jeu_Ven_Sam'.split('_'),
        weekdaysMin: 'Di_Lu_Ma_Me_Je_Ve_Sa'.split('_'),
        longDateFormat: {
          LT: 'HH:mm',
          LTS: 'HH:mm:ss',
          L: 'DD/MM/YYYY',
          LL: 'D MMMM YYYY',
          LLL: 'D MMMM YYYY LT',
          LLLL: 'dddd D MMMM YYYY LT'

          sameDay: "[Aujourd'hui à] LT",
          nextDay: '[Demain à] LT',
          nextWeek: 'dddd [à] LT',
          lastDay: '[Hier à] LT',
          lastWeek: 'dddd [dernier à] LT',
          sameElse: 'L'
        },
        relativeTime: {
          future: 'dans %s',
          past: 'il y a %s',
          s: 'quelques secondes',
          m: 'une minute',
          mm: '%d minutes',

        },
        ordinalParse: /\d{1,2}(er|ème)/,
        ordinal: function(number) {
          return number + (number === 1 ? 'er' : 'ème');
        },
        meridiemParse: /PD|MD/,
        isPM: function(input) {
          return input.charAt(0) === 'M';
        },
        // in case the meridiem units are not separated around 12, then implement
        // this function (look at locale/id.js for an example)
        // meridiemHour : function (hour, meridiem) {
        //     return /* 0-23 hour, given meridiem token and hour 1-12 */
        // },
        meridiem: function(hours, minutes, isLower) {
          return hours < 12 ? 'PD' : 'MD';
        },
        week: {
          dow: 1, // Monday is the first day of the week.
          doy: 4 // The week that contains Jan 4th is the first week of the year.
        }
      }
    };
    

    Device Specific Notes

    • OnePlus devices use OnePlus Slate font by default which causes text being cut off in the date number in react-native-calendar-strip. To overcome this change the default font of the device or use a specific font throughout your app.

    Development with Sample Application

    To facilitate development, the example directory has a sample app.

    cd example
    npm run cp
    npm install
    npm start
    

    The CalendarStrip source files are copied from the project root directory into example/CalendarStrip using npm run cp. If a source file is modified, it must be copied over again with npm run cp.
