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);

      datesBlacklist={datesBlacklistFunc}
    />
  );

markedDates Example

markedDates may be an array of dates with dots/lines, or a callback that returns the same shaped object for a date passed to it.

  // Marked dates array format
  markedDatesArray = [
    {
      date: '(string, Date or Moment object)',
      dots: [

customDatesStyles

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'},
      }
    }
  }

  render() {
    return (
      <CalendarStrip
        customDatesStyles={customDatesStylesFunc}
        ...
      />
    );
  }

Responsive Sizing

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. |

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

$ 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',

      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',
      h: 'une heure',
      hh: '%d heures',
      d: 'un jour',
      dd: '%d jours',
      M: 'un mois',
      MM: '%d mois',
      y: 'une année',
      yy: '%d années'
    },
    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
