An easily internationalizable, mobile-friendly datepicker library for the web
An easily internationalizable, accessible, mobile-friendly datepicker library for the web.
For examples of the datepicker in action, go to react-dates.github.io.
OR
To run that demo on your own computer:
npm installnpm run storybookEnsure packages are installed with correct version numbers by running (from your command line):
( export PKG=react-dates; npm info "$PKG" peerDependencies --json | command sed 's/[\{\},]//g ; s/: /@/g; s/ *//g' | xargs npm install --save "$PKG" )
Which produces and runs a command like:
npm install --save react-dates moment@>=#.## react@>=#.## react-dom@>=#.##
If you are running Windows, that command will not work, but if you are running npm 5 or higher, you can run
npx install-peerdeps react-dateson any platform
import 'react-dates/initialize';
As of v13.0.0 of react-dates, this project relies on react-with-styles. If you want to continue using CSS stylesheets and classes, there is a little bit of extra set-up required to get things going. As such, you need to import react-dates/initialize to set up class names on our components. This import should go at the top of your application as you won't be able to import any react-dates components without it.
Note: This component assumes box-sizing: border-box is set globally in your page's CSS.
import { DateRangePicker, SingleDatePicker, DayPickerRangeController } from 'react-dates';
Using Webpack with CSS loader, add the following import to your app:
import 'react-dates/lib/css/_datepicker.css';
Create a CSS file with the contents of require.resolve('react-dates/lib/css/_datepicker.css') and include it in your html <head> section.
To see this in action, you can check out https://github.com/majapw/react-dates-demo which adds react-dates on top of a simple create-react-app setup.
By default react-dates will use PureComponent conditionally if it is available. However, it is possible to override this setting and use Component and shouldComponentUpdate instead. It is also possible to override the logic in build/util/baseClass if you know that you are using a React version with PureComponent.
import React from 'react'; export default React.PureComponent; export const pureComponentAvailable = true;
Right now, the easiest way to tweak react-dates to your heart's content is to create another stylesheet to override the default react-dates styles. For example, you could create a file named react_dates_overrides.css with the following contents (Make sure when you import said file to your app.js, you import it after the react-dates styles):
// NOTE: the order of these styles DO matter // Will edit everything selected including everything between a range of dates .CalendarDay__selected_span { background: #82e0aa; //background color: white; //text border: 1px solid $light-red; //default styles include a border } // Will edit selected date or the endpoints of a range of dates .CalendarDay__selected { background: $dark-red; color: white; } // Will edit when hovered over. _span style also has this property .CalendarDay__selected:hover { background: orange; color: white; } // Will edit when the second date (end date) in a range of dates // is not yet selected. Edits the dates between your mouse and said date .CalendarDay__hovered_span:hover, .CalendarDay__hovered_span { background: brown; }
This would override the background and text colors applied to highlighted calendar days. You can use this method with the default set-up to override any aspect of the calendar to have it better fit to your particular needs. If there are any styles that you need that aren't listed here, you can always check the source css of each element.
We provide a handful of components for your use. If you supply essential props to each component, you'll get a full featured interactive date picker. With additional optional props, you can customize the look and feel of the inputs, calendar, etc. You can see what each of the props do in the live demo or explore how to properly wrap the pickers in the examples folder.
The DateRangePicker is a fully controlled component that allows users to select a date range. You can control the selected
dates using the startDate, endDate, and onDatesChange props as shown below. The DateRangePicker also manages internal
state for partial dates entered by typing (although onDatesChange will not trigger until a date has been entered
completely in that case). Similarly, you can control which input is focused as well as calendar visibility (the calendar is
only visible if focusedInput is defined) with the focusedInput and onFocusChange props as shown below.
Here is the minimum REQUIRED setup you need to get the DateRangePicker working:
<DateRangePicker startDate={this.state.startDate} // momentPropTypes.momentObj or null, startDateId="your_unique_start_date_id" // PropTypes.string.isRequired, endDate={this.state.endDate} // momentPropTypes.momentObj or null, endDateId="your_unique_end_date_id" // PropTypes.string.isRequired, onDatesChange={({ startDate, endDate }) => this.setState({ startDate, endDate })} // PropTypes.func.isRequired, focusedInput={this.state.focusedInput} // PropTypes.oneOf([START_DATE, END_DATE]) or null, onFocusChange={focusedInput => this.setState({ focusedInput })} // PropTypes.func.isRequired, />
The following is a list of other OPTIONAL props you may provide to the DateRangePicker to customize appearance and behavior to your heart's desire. All constants (indicated by ALL_CAPS) are provided as named exports in react-dates/constants. Please explore the storybook for more information on what each of these props do.
// input related props startDatePlaceholderText: PropTypes.string, endDatePlaceholderText: PropTypes.string, startDateAriaLabel: PropTypes.string, endDateAriaLabel: PropTypes.string, startDateTitleText: PropTypes.string, endDateTitleText: PropTypes.string, disabled: PropTypes.oneOfType([PropTypes.bool, PropTypes.oneOf([START_DATE, END_DATE])]), required: PropTypes.bool, readOnly: PropTypes.bool, screenReaderInputMessage: PropTypes.string, showClearDates: PropTypes.bool, showDefaultInputIcon: PropTypes.bool, customInputIcon: PropTypes.node, customArrowIcon: PropTypes.node, customCloseIcon: PropTypes.node, inputIconPosition: PropTypes.oneOf([ICON_BEFORE_POSITION, ICON_AFTER_POSITION]), noBorder: PropTypes.bool, block: PropTypes.bool, small: PropTypes.bool, regular: PropTypes.bool, autoComplete: PropTypes.string, // calendar presentation and interaction related props renderMonthText: mutuallyExclusiveProps(PropTypes.func, 'renderMonthText', 'renderMonthElement'), // (month) => PropTypes.string, orientation: PropTypes.oneOf([HORIZONTAL_ORIENTATION, VERTICAL_ORIENTATION]), anchorDirection: PropTypes.oneOf([ANCHOR_LEFT, ANCHOR_RIGHT]), openDirection: PropTypes.oneOf([OPEN_DOWN, OPEN_UP]), horizontalMargin: PropTypes.number, withPortal: PropTypes.bool, withFullScreenPortal: PropTypes.bool, appendToBody: PropTypes.bool, disableScroll: PropTypes.bool, daySize: nonNegativeInteger, isRTL: PropTypes.bool, initialVisibleMonth: PropTypes.func, firstDayOfWeek: PropTypes.oneOf([0, 1, 2, 3, 4, 5, 6]), numberOfMonths: PropTypes.number, keepOpenOnDateSelect: PropTypes.bool, reopenPickerOnClearDates: PropTypes.bool, renderCalendarInfo: PropTypes.func, renderMonthElement: mutuallyExclusiveProps(PropTypes.func, 'renderMonthText', 'renderMonthElement'), PropTypes.func, // ({ month, onMonthSelect, onYearSelect, isVisible }) => PropTypes.node, hideKeyboardShortcutsPanel: PropTypes.bool, verticalSpacing: PropTypes.number, // navigation related props navPrev: PropTypes.node, navNext: PropTypes.node, onPrevMonthClick: PropTypes.func, onNextMonthClick: PropTypes.func, onClose: PropTypes.func, transitionDuration: nonNegativeInteger, // milliseconds // day presentation and interaction related props renderCalendarDay: PropTypes.func, renderDayContents: PropTypes.func, minimumNights: PropTypes.number, minDate: momentPropTypes.momentObj, maxDate: momentPropTypes.momentObj, enableOutsideDays: PropTypes.bool, isDayBlocked: PropTypes.func, isOutsideRange: PropTypes.func, isDayHighlighted: PropTypes.func, // internationalization props displayFormat: PropTypes.oneOfType([PropTypes.string, PropTypes.func]), monthFormat: PropTypes.string, weekDayFormat: PropTypes.string, phrases: PropTypes.shape(getPhrasePropTypes(DateRangePickerPhrases)), dayAriaLabelFormat: PropTypes.string,
The SingleDatePicker is a fully controlled component that allows users to select a single date. You can control the selected
date using the date and onDateChange props as shown below. The SingleDatePicker also manages internal
state for partial dates entered by typing (although onDateChange will not trigger until a date has been entered
completely in that case). Similarly, you can control whether or not the input is focused (calendar visibility is also
controlled with the same props) with the focused and onFocusChange props as shown below.
Here is the minimum REQUIRED setup you need to get the SingleDatePicker working:
<SingleDatePicker date={this.state.date} // momentPropTypes.momentObj or null onDateChange={date => this.setState({ date })} // PropTypes.func.isRequired focused={this.state.focused} // PropTypes.bool onFocusChange={({ focused }) => this.setState({ focused })} // PropTypes.func.isRequired id="your_unique_id" // PropTypes.string.isRequired, />
The following is a list of other OPTIONAL props you may provide to the SingleDatePicker to customize appearance and behavior to your heart's desire. All constants (indicated by ALL_CAPS) are provided as named exports in react-dates/constants. Please explore the storybook for more information on what each of these props do.
// input related props placeholder: PropTypes.string, ariaLabel: PropTypes.string, titleText: PropTypes.string, disabled: PropTypes.bool, required: PropTypes.bool, readOnly: PropTypes.bool, screenReaderInputMessage: PropTypes.string, showClearDate: PropTypes.bool, customCloseIcon: PropTypes.node, showDefaultInputIcon: PropTypes.bool, customInputIcon: PropTypes.node, inputIconPosition: PropTypes.oneOf([ICON_BEFORE_POSITION, ICON_AFTER_POSITION]), noBorder: PropTypes.bool, block: PropTypes.bool, small: PropTypes.bool, regular: PropTypes.bool, autoComplete: PropTypes.string, // calendar presentation and interaction related props renderMonthText: mutuallyExclusiveProps(PropTypes.func, 'renderMonthText', 'renderMonthElement'), // (month) => PropTypes.string, orientation: PropTypes.oneOf([HORIZONTAL_ORIENTATION, VERTICAL_ORIENTATION]), anchorDirection: PropTypes.oneOf([ANCHOR_LEFT, ANCHOR_RIGHT]), openDirection: PropTypes.oneOf([OPEN_DOWN, OPEN_UP]), horizontalMargin: PropTypes.number, withPortal: PropTypes.bool, withFullScreenPortal: PropTypes.bool, appendToBody: PropTypes.bool, disableScroll: PropTypes.bool, initialVisibleMonth: PropTypes.func, firstDayOfWeek: PropTypes.oneOf([0, 1, 2, 3, 4, 5, 6]), numberOfMonths: PropTypes.number, keepOpenOnDateSelect: PropTypes.bool, reopenPickerOnClearDate: PropTypes.bool, renderCalendarInfo: PropTypes.func, renderMonthElement: mutuallyExclusiveProps(PropTypes.func, 'renderMonthText', 'renderMonthElement'), // ({ month, onMonthSelect, onYearSelect, isVisible }) => PropTypes.node, hideKeyboardShortcutsPanel: PropTypes.bool, daySize: nonNegativeInteger, isRTL: PropTypes.bool, verticalSpacing: PropTypes.number, // navigation related props navPrev: PropTypes.node, navNext: PropTypes.node, onPrevMonthClick: PropTypes.func, onNextMonthClick: PropTypes.func, onClose: PropTypes.func, transitionDuration: nonNegativeInteger, // milliseconds // day presentation and interaction related props renderCalendarDay: PropTypes.func, renderDayContents: PropTypes.func, enableOutsideDays: PropTypes.bool, isDayBlocked: PropTypes.func, isOutsideRange: PropTypes.func, isDayHighlighted: PropTypes.func, // internationalization props displayFormat: PropTypes.oneOfType([PropTypes.string, PropTypes.func]), monthFormat: PropTypes.string, weekDayFormat: PropTypes.string, phrases: PropTypes.shape(getPhrasePropTypes(SingleDatePickerPhrases)), dayAriaLabelFormat: PropTypes.string,
The DayPickerRangeController is a calendar-only version of the DateRangePicker. There are no inputs (which also means
that currently, it is not keyboard accessible) and the calendar is always visible, but you can select a date range much in the same way you would with the DateRangePicker. You can control the selected
dates using the startDate, endDate, and onDatesChange props as shown below. Similarly, you can control which input is focused with the focusedInput and onFocusChange props as shown below. The user will only be able to select a date if focusedInput is provided.
Here is the minimum REQUIRED setup you need to get the DayPickerRangeController working:
<DayPickerRangeController startDate={this.state.startDate} // momentPropTypes.momentObj or null, endDate={this.state.endDate} // momentPropTypes.momentObj or null, onDatesChange={({ startDate, endDate }) => this.setState({ startDate, endDate })} // PropTypes.func.isRequired, focusedInput={this.state.focusedInput} // PropTypes.oneOf([START_DATE, END_DATE]) or null, onFocusChange={focusedInput => this.setState({ focusedInput })} // PropTypes.func.isRequired, initialVisibleMonth={() => moment().add(2, "M")} // PropTypes.func or null, />
The following is a list of other OPTIONAL props you may provide to the DayPickerRangeController to customize appearance and behavior to your heart's desire. Again, please explore the storybook for more information on what each of these props do.
// calendar presentation and interaction related props enableOutsideDays: PropTypes.bool, numberOfMonths: PropTypes.number, orientation: ScrollableOrientationShape, withPortal: PropTypes.bool, initialVisibleMonth: PropTypes.func, renderCalendarInfo: PropTypes.func, renderMonthElement: mutuallyExclusiveProps(PropTypes.func, 'renderMonthText', 'renderMonthElement'), // ({ month, onMonthSelect, onYearSelect, isVisible }) => PropTypes.node, onOutsideClick: PropTypes.func, keepOpenOnDateSelect: PropTypes.bool, noBorder: PropTypes.bool, // navigation related props navPrev: PropTypes.node, navNext: PropTypes.node, onPrevMonthClick: PropTypes.func, onNextMonthClick: PropTypes.func, transitionDuration: nonNegativeInteger, // milliseconds // day presentation and interaction related props renderCalendarDay: PropTypes.func, renderDayContents: PropTypes.func, minimumNights: PropTypes.number, isOutsideRange: PropTypes.func, isDayBlocked: PropTypes.func, isDayHighlighted: PropTypes.func, // internationalization props monthFormat: PropTypes.string, weekDayFormat: PropTypes.string, phrases: PropTypes.shape(getPhrasePropTypes(DayPickerPhrases)), dayAriaLabelFormat: PropTypes.string, />
Moment.js is a peer dependency of react-dates. The latter then uses a single instance of moment which is imported in one’s project. Loading a locale is done by calling moment.locale(..) in the component where moment is imported, with the locale key of choice. For instance:
moment.locale('pl'); // Polish
However, this only solves date localization. For complete internationalization of the components, react-dates defines a certain amount of user interface strings in English which can be changed through the phrases prop (explore the storybook for examples). For accessibility and usability concerns, all these UI elements should be translated.
react-dates no longer relies strictly on CSS, but rather relies on react-with-styles as an abstraction layer between how styles are applied and how they are written. The instructions above will get the project working out of the box, but there's a lot more customization that can be done.
The react-dates/initialize script actually relies on react-with-styles-interface-css under the hood. If you are interested in a different solution for styling in your project, you can do your own initialization of a another interface. At Airbnb, for instance, we rely on Aphrodite under the hood and therefore use the Aphrodite interface for react-with-styles. If you want to do the same, you would use the following pattern:
import ThemedStyleSheet from 'react-with-styles/lib/ThemedStyleSheet'; import aphroditeInterface from 'react-with-styles-interface-aphrodite'; import DefaultTheme from 'react-dates/lib/theme/DefaultTheme'; ThemedStyleSheet.registerInterface(aphroditeInterface); ThemedStyleSheet.registerTheme(DefaultTheme);
The above code has to be run before any react-dates component is imported. Otherwise, you will get an error. Also note that if you register any custom interface manually, you must also manually register a theme.
react-dates also now supports a different way to theme. You can see the default theme values in this file and you would override them in the following manner:
import ThemedStyleSheet from 'react-with-styles/lib/ThemedStyleSheet'; import aphroditeInterface from 'react-with-styles-interface-aphrodite'; import DefaultTheme from 'react-dates/lib/theme/DefaultTheme'; ThemedStyleSheet.registerInterface(aphroditeInterface); ThemedStyleSheet.registerTheme({ reactDates: { ...DefaultTheme.reactDates, color: { ...DefaultTheme.reactDates.color, highlighted: { backgroundColor: '#82E0AA', backgroundColor_active: '#58D68D', backgroundColor_hover: '#58D68D', color: '#186A3B', color_active: '#186A3B', color_hover: '#186A3B', }, }, }, });
The above code would use shades of green instead of shades of yellow for the highlight color on CalendarDay components. Note that you must register an interface if you manually register a theme. One will not work without the other.
The default interface that react-dates ships with is the CSS interface. If you want to use this interface along with the theme registration method, you will need to rebuild the core _datepicker.css file. We do not currently expose a utility method to build this file, but you can follow along with the code in https://github.com/react-dates/react-dates/blob/HEAD/scripts/buildCSS.js to build your own custom themed CSS file.
