Malicious npm Packages Inject SSH Backdoors via Typosquatted Libraries
Socket’s threat research team has detected six malicious npm packages typosquatting popular libraries to insert SSH backdoors.
@alexstrat/react-native-calendars
Advanced tools
This module includes various customizable React-Native calendar components.
The package is both Android and iOS compatible.
You can run example module by performing these steps:
$ git clone git@github.com:wix/react-native-calendars.git
$ npm install
$ react-native run-ios
You can check example screens source code in example module screens
This project is compatible with Expo/CRNA (without ejecting), and the examples have been published on Expo
$ npm install --save react-native-calendars
The solution is implemented in JavaScript so no native module linking is required.
import {
Calendar, CalendarList, Agenda} from 'react-native-calendars';
All parameters for components are optional. By default the month of current local date will be displayed.
Event handler callbacks are called with calendar objects
like this:
{
day: 1, // day of month (1-31)
month: 1, // month of year (1-12)
year: 2017, // year
timestamp, // UTC timestamp representing 00:00 AM of this date
dateString: '2016-05-13' // date formatted as 'YYYY-MM-DD' string
}
Parameters that require date types accept YYYY-MM-DD
formated date-strings
, JavaScript date objects, calendar objects
and UTC timestamps
.
Calendars can be localized by adding custom locales to LocaleConfig
object:
import {LocaleConfig} from 'react-native-calendars';
LocaleConfig.locales['fr'] = {
monthNames: [
'Janvier',
'Février',
'Mars',
'Avril',
'Mai',
'Juin',
'Juillet',
'Août',
'Septembre',
'Octobre',
'Novembre',
'Décembre'
],
monthNamesShort: ['Janv.', 'Févr.', 'Mars', 'Avril', 'Mai', 'Juin', 'Juil.', 'Août', 'Sept.', 'Oct.', 'Nov.', 'Déc.'],
dayNames: ['Dimanche', 'Lundi', 'Mardi', 'Mercredi', 'Jeudi', 'Vendredi', 'Samedi'],
dayNamesShort: ['Dim.', 'Lun.', 'Mar.', 'Mer.', 'Jeu.', 'Ven.', 'Sam.'],
today: "Aujourd'hui"
};
LocaleConfig.defaultLocale = 'fr';
<Calendar
// Initially visible month. Default = Date()
current={'2012-03-01'}
// Minimum date that can be selected, dates before minDate will be grayed out. Default = undefined
minDate={'2012-05-10'}
// Maximum date that can be selected, dates after maxDate will be grayed out. Default = undefined
maxDate={'2012-05-30'}
// Handler which gets executed on day press. Default = undefined
onDayPress={day => {
console.log('selected day', day);
}}
// Handler which gets executed on day long press. Default = undefined
onDayLongPress={day => {
console.log('selected day', day);
}}
// Month format in calendar title. Formatting values: http://arshaw.com/xdate/#Formatting
monthFormat={'yyyy MM'}
// Handler which gets executed when visible month changes in calendar. Default = undefined
onMonthChange={month => {
console.log('month changed', month);
}}
// Hide month navigation arrows. Default = false
hideArrows={true}
// Replace default arrows with custom ones (direction can be 'left' or 'right')
renderArrow={direction => <Arrow />}
// Do not show days of other months in month page. Default = false
hideExtraDays={true}
// If hideArrows=false and hideExtraDays=false do not switch month when tapping on greyed out
// day from another month that is visible in calendar page. Default = false
disableMonthChange={true}
// If firstDay=1 week starts from Monday. Note that dayNames and dayNamesShort should still start from Sunday.
firstDay={1}
// Hide day names. Default = false
hideDayNames={true}
// Show week numbers to the left. Default = false
showWeekNumbers={true}
// Handler which gets executed when press arrow icon left. It receive a callback can go back month
onPressArrowLeft={subtractMonth => subtractMonth()}
// Handler which gets executed when press arrow icon right. It receive a callback can go next month
onPressArrowRight={addMonth => addMonth()}
// Disable left arrow. Default = false
disableArrowLeft={true}
// Disable right arrow. Default = false
disableArrowRight={true}
// Disable all touch events for disabled days. can be override with disableTouchEvent in markedDates
disableAllTouchEventsForDisabledDays={true}
// Replace default month and year title with custom one. the function receive a date as parameter.
renderHeader={date => {
/*Return JSX*/
}}
// Enable the option to swipe between months. Default = false
enableSwipeMonths={true}
// A `react-native-swipe-gestures` config used to detect swipe of months. Default = undefined
swipeMonthsConfig={{velocityThreshold: 0.3, directionalOffsetThreshold: 80, gestureIsClickThreshold: 5}}
/>
Disclaimer: Make sure that markedDates
param is immutable. If you change markedDates
object content but the reference to it does not change calendar update will not be triggered.
Dot marking
<Calendar
// Collection of dates that have to be marked. Default = {}
markedDates={{
'2012-05-16': {selected: true, marked: true, selectedColor: 'blue'},
'2012-05-17': {marked: true},
'2012-05-18': {marked: true, dotColor: 'red', activeOpacity: 0},
'2012-05-19': {disabled: true, disableTouchEvent: true}
}}
/>
You can customize a dot color for each day independently.
Multi-Dot marking
Use markingType={'multi-dot'}
if you want to display more than one dot. Both the <Calendar/>
and <CalendarList/>
support multiple dots by using dots
array in markedDates
prop.
The property color
is mandatory while key
and selectedColor
are optional. If key is omitted then the array index is used as key. If selectedColor
is omitted then color
will be used for selected dates.
const vacation = {key: 'vacation', color: 'red', selectedDotColor: 'blue'};
const massage = {key: 'massage', color: 'blue', selectedDotColor: 'blue'};
const workout = {key: 'workout', color: 'green'};
<Calendar
markedDates={{
'2017-10-25': {dots: [vacation, massage, workout], selected: true, selectedColor: 'red'},
'2017-10-26': {dots: [massage, workout], disabled: true}
}}
markingType={'multi-dot'}
/>;
Period marking
<Calendar
// Collection of dates that have to be colored in a special way. Default = {}
markedDates={{
'2012-05-20': {textColor: 'green'},
'2012-05-22': {startingDay: true, color: 'green'},
'2012-05-23': {selected: true, endingDay: true, color: 'green', textColor: 'gray'},
'2012-05-04': {disabled: true, startingDay: true, color: 'green', endingDay: true}
}}
// Date marking style [simple/period/multi-dot/custom]. Default = 'simple'
markingType={'period'}
/>
Multi-period marking
CAUTION: This marking is only fully supported by the <Calendar/>
component because it expands its height. Usage with <CalendarList/>
might lead to overflow issues.
<Calendar
markedDates={{
'2017-12-14': {
periods: [
{startingDay: false, endingDay: true, color: '#5f9ea0'},
{startingDay: false, endingDay: true, color: '#ffa500'},
{startingDay: true, endingDay: false, color: '#f0e68c'}
]
},
'2017-12-15': {
periods: [
{startingDay: true, endingDay: false, color: '#ffa500'},
{color: 'transparent'},
{startingDay: false, endingDay: false, color: '#f0e68c'}
]
}
}}
// Date marking style [simple/period/multi-dot/custom]. Default = 'simple'
markingType="multi-period"
/>
Custom marking allows you to customize each marker with custom styles.
<Calendar
// Date marking style [simple/period/multi-dot/single]. Default = 'simple'
markingType={'custom'}
markedDates={{
'2018-03-28': {
customStyles: {
container: {
backgroundColor: 'green'
},
text: {
color: 'black',
fontWeight: 'bold'
}
}
},
'2018-03-29': {
customStyles: {
container: {
backgroundColor: 'white',
elevation: 2
},
text: {
color: 'blue'
}
}
}
}}
/>
NEW! While we still don't support multi marking type, we add the possibility to combine between period
and simple
.
<Calendar
markingType={'period'}
markedDates={{
'2012-05-15': {marked: true, dotColor: '#50cebb'},
'2012-05-16': {marked: true, dotColor: '#50cebb'},
'2012-05-21': {startingDay: true, color: '#50cebb', textColor: 'white'},
'2012-05-22': {color: '#70d7c7', textColor: 'white'},
'2012-05-23': {color: '#70d7c7', textColor: 'white', marked: true, dotColor: 'white'},
'2012-05-24': {color: '#70d7c7', textColor: 'white'},
'2012-05-25': {endingDay: true, color: '#50cebb', textColor: 'white'}
}}
/>
Keep in mind that different marking types are not compatible. You can use just one marking style for a calendar.
The loading indicator next to the month name will be displayed if <Calendar/>
has displayLoadingIndicator
prop and the markedDates
collection does not have a value for every day of the month in question. When you load data for days, just set []
or special marking value to all days in markedDates
collection.
<Calendar
// Specify style for calendar container element. Default = {}
style={{
borderWidth: 1,
borderColor: 'gray',
height: 350
}}
// Specify theme properties to override specific styles for calendar parts. Default = {}
theme={{
backgroundColor: '#ffffff',
calendarBackground: '#ffffff',
textSectionTitleColor: '#b6c1cd',
textSectionTitleDisabledColor: '#d9e1e8',
selectedDayBackgroundColor: '#00adf5',
selectedDayTextColor: '#ffffff',
todayTextColor: '#00adf5',
dayTextColor: '#2d4150',
textDisabledColor: '#d9e1e8',
dotColor: '#00adf5',
selectedDotColor: '#ffffff',
arrowColor: 'orange',
disabledArrowColor: '#d9e1e8',
monthTextColor: 'blue',
indicatorColor: 'blue',
textDayFontFamily: 'monospace',
textMonthFontFamily: 'monospace',
textDayHeaderFontFamily: 'monospace',
textDayFontWeight: '300',
textMonthFontWeight: 'bold',
textDayHeaderFontWeight: '300',
textDayFontSize: 16,
textMonthFontSize: 16,
textDayHeaderFontSize: 16
}}
/>
<Calendar
theme={{
textSectionTitleDisabledColor: '#d9e1e8'
}}
disabledDaysIndexes={[0, 6]}
markedDates={{
...this.getDisabledDates('2012-05-01', '2012-05-30', [0, 6])
}}
/>
If you want to have complete control over the calendar styles you can do it by overriding default style.js
files. For example, if you want to override <CalendarHeader/>
style first you have to find stylesheet id for this file:
https://github.com/wix/react-native-calendars/blob/master/src/calendar/header/style.js#L4
In this case it is stylesheet.calendar.header
. Next you can add overriding stylesheet to your theme with this id.
https://github.com/wix/react-native-calendars/blob/master/example/src/screens/calendars.js#L56
theme={{
arrowColor: 'white',
'stylesheet.calendar.header': {
week: {
marginTop: 5,
flexDirection: 'row',
justifyContent: 'space-between'
}
}
}}
Disclaimer: Issues that arise because something breaks after using stylesheet override will not be supported. Use this option at your own risk.
If you need custom functionality not supported by current day component implementations you can pass your own custom day component to the calendar.
<Calendar
style={[styles.calendar, {height: 300}]}
dayComponent={({date, state}) => {
return (
<View>
<Text style={{textAlign: 'center', color: state === 'disabled' ? 'gray' : 'black'}}>{date.day}</Text>
</View>
);
}}
/>
The dayComponent
prop has to receive a RN component or a function that receive props. The dayComponent
will receive such props:
markedDates
value for this day.Tip: Don't forget to implement shouldComponentUpdate()
for your custom day component to make the calendar perform better
If you implement an awesome day component please make a PR so that other people could use it :)
<CalendarList/>
is scrollable semi-infinite calendar composed of <Calendar/>
components. Currently it is possible to scroll 4 years back and 4 years to the future. All parameters that are available for <Calendar/>
are also available for this component. There are also some additional params that can be used:
<CalendarList
// Callback which gets executed when visible months change in scroll view. Default = undefined
onVisibleMonthsChange={(months) => {console.log('now these months are visible', months);}}
// Max amount of months allowed to scroll to the past. Default = 50
pastScrollRange={50}
// Max amount of months allowed to scroll to the future. Default = 50
futureScrollRange={50}
// Enable or disable scrolling of calendar list
scrollEnabled={true}
// Enable or disable vertical scroll indicator. Default = false
showScrollIndicator={true}
...calendarParams
/>
You can also make the CalendarList
scroll horizontally. To do that you need to pass specific props to the CalendarList
:
<CalendarList
// Enable horizontal scrolling, default = false
horizontal={true}
// Enable paging on horizontal, default = false
pagingEnabled={true}
// Set custom calendarWidth.
calendarWidth={320}
...calendarListParams
...calendarParams
/>
An advanced Agenda
component that can display interactive listings for calendar day items.
<Agenda
// The list of items that have to be displayed in agenda. If you want to render item as empty date
// the value of date key has to be an empty array []. If there exists no value for date key it is
// considered that the date in question is not yet loaded
items={{
'2012-05-22': [{name: 'item 1 - any js object'}],
'2012-05-23': [{name: 'item 2 - any js object', height: 80}],
'2012-05-24': [],
'2012-05-25': [{name: 'item 3 - any js object'}, {name: 'any js object'}]
}}
// Callback that gets called when items for a certain month should be loaded (month became visible)
loadItemsForMonth={month => {
console.log('trigger items loading');
}}
// Callback that fires when the calendar is opened or closed
onCalendarToggled={calendarOpened => {
console.log(calendarOpened);
}}
// Callback that gets called on day press
onDayPress={day => {
console.log('day pressed');
}}
// Callback that gets called when day changes while scrolling agenda list
onDayChange={day => {
console.log('day changed');
}}
// Initially selected day
selected={'2012-05-16'}
// Minimum date that can be selected, dates before minDate will be grayed out. Default = undefined
minDate={'2012-05-10'}
// Maximum date that can be selected, dates after maxDate will be grayed out. Default = undefined
maxDate={'2012-05-30'}
// Max amount of months allowed to scroll to the past. Default = 50
pastScrollRange={50}
// Max amount of months allowed to scroll to the future. Default = 50
futureScrollRange={50}
// Specify how each item should be rendered in agenda
renderItem={(item, firstItemInDay) => {
return <View />;
}}
// Specify how each date should be rendered. day can be undefined if the item is not first in that day.
renderDay={(day, item) => {
return <View />;
}}
// Specify how empty date content with no items should be rendered
renderEmptyDate={() => {
return <View />;
}}
// Specify how agenda knob should look like
renderKnob={() => {
return <View />;
}}
// Specify what should be rendered instead of ActivityIndicator
renderEmptyData={() => {
return <View />;
}}
// Specify your item comparison function for increased performance
rowHasChanged={(r1, r2) => {
return r1.text !== r2.text;
}}
// Hide knob button. Default = false
hideKnob={true}
// By default, agenda dates are marked if they have at least one item, but you can override this if needed
markedDates={{
'2012-05-16': {selected: true, marked: true},
'2012-05-17': {marked: true},
'2012-05-18': {disabled: true}
}}
// If disabledByDefault={true} dates flagged as not disabled will be enabled. Default = false
disabledByDefault={true}
// If provided, a standard RefreshControl will be added for "Pull to Refresh" functionality. Make sure to also set the refreshing prop correctly.
onRefresh={() => console.log('refreshing...')}
// Set this true while waiting for new data from a refresh
refreshing={false}
// Add a custom RefreshControl component, used to provide pull-to-refresh functionality for the ScrollView.
refreshControl={null}
// Agenda theme
theme={{
...calendarTheme,
agendaDayTextColor: 'yellow',
agendaDayNumColor: 'green',
agendaTodayColor: 'red',
agendaKnobColor: 'blue'
}}
// Agenda container style
