Which produces and runs a command like:

npm install --save react-dates moment@>=#.## react@>=#.## react-dom@>=#.## react-addons-shallow-compare@>=#.##

API

We have a handful of different components and utilities available for all of your date picking needs!

`DateRangePicker`

This fully-controlled component is designed to allow a user to select both a start date and an end date. It is best suited for a selecting a relatively short date range some time in the next year.

`Props`

Dates:

Moment objects representing the currently selected start and end dates. To indicate that a date has not yet been selected, these are set to null.

  startDate: momentPropTypes.momentObj
  endDate: momentPropTypes.momentObj

onDatesChange is the callback necessary to update the date state being held in the parent component and pass that back down to the DateRangePicker as props. onDatesChange receives an object of the form { startDate: momentPropTypes.momentObj, endDate: momentPropTypes.momentObj } as an argument.

  onDatesChange: PropTypes.func

Focus:

The focusedInput prop indicates which of the two inputs is currently focused, if either. You can import the START_DATE and END_DATE constants from react-dates/constants.

  focusedInput: PropTypes.oneOf([START_DATE, END_DATE])

onFocusChange is the callback necessary to update the focus state being held in the parent component and pass that back down to the DateRangePicker as a prop. onFocusChange receives either START_DATE, END_DATE, or null as an argument.

  onFocusChange: PropTypes.func

Date selection rules:

The value of minimumNights indicates the minimum number of days between the start date and the end date.

  minimumNights: PropTypes.number

To indicate which days are blocked from selection, you may provide a function to the isDayBlocked prop. As of v1.0.0, we allow blocked dates inside of ranges.

  isDayBlocked: PropTypes.func

isOutsideRange indicates which days are out of selectable range. Past dates out of range by default. If you would like to allow the user to select days in the past, you may set isOutsideRange to () => false.

Right now we have an expectation that this function returns true for a continuous range of dates from -Infinity to some date and/or from some date to +Infinity. This is relevant to the minimum nights logic. If you would like to prevent the user from selecting a non-continuous set of dates, you should use isDayBlocked instead.

  isOutsideRange: PropTypes.func

Calendar presentation:

numberOfMonths indicates the number of visible months at a time.

  numberOfMonths: PropTypes.number

By default, we do not show days from the previous month and the next month in the same table as the currently visible month. However, sometimes, and especially if the numberOfMonths prop is set to 1, it might make sense to allow users to see these days as well. To do, you may set enabledOutsideDays to true. These days can still be styled by selecting on the CalendarMonth__day--outside class.

  enableOutsideDays: PropTypes.bool

DayPicker presentation:

The orientation prop indicates whether months are stacked on top of each other or displayed side-by-side. You can import the HORIZONTAL_ORIENTATION and VERTICAL_ORIENTATION constants from react-dates/constants.

  orientation: PropTypes.oneOf([HORIZONTAL_ORIENTATION, VERTICAL_ORIENTATION])

withPortal was designed for use on mobile devices. Namely, if this prop is set to true, the DayPicker will be rendered centrally on the screen, above the current plane, with a transparent black background behind it. Clicking on the background will hide the DayPicker. This option is currently only available for a DateRangePicker with a horizontal orientation.

  withPortal: PropTypes.bool

withFullScreenPortal is a full-screen takeover version of the withPortal prop. Similarly to withPortal, the DayPicker is rendered centrally on the screen, above the current plane. However, instead of a clickable transparent black background, the background is solid and white. To close the datepicker, the user must either select a date or click the close button located at the top right of the screen.

  withFullScreenPortal: PropTypes.bool

Input presentation:

The startDateId and endDateId props are assigned to the actual <input> DOM elements for accessibility reasons. They default to the values of the START_DATE and END_DATE constants.

  startDateId: PropTypes.string
  endDateId: PropTypes.string

The startDatePlaceholderText and endDatePlaceholderText props are the placeholders for the two inputs. As of v1.0.0, they are also used as the label text for their respective inputs.

  startDatePlaceholderText: PropTypes.string,
  endDatePlaceholderText: PropTypes.string,

If the showClearDates prop is set to true, an x shows up in the input box that allows you to clear out both dates and reset the input.

  showClearDates: PropTypes.bool,

If the disabled prop is set to true, onFocusChange is not called when onStartDateFocus or onEndDateFocus are invoked and disabled is assigned to the actual <input> DOM elements.

  disabled: PropTypes.bool,

Some useful callbacks:

If you need to do something when the user navigates between months (for instance, check the availability of a listing), you can do so using the onPrevMonthClick and onNextMonthClick props.

  onPrevMonthClick: PropTypes.func,
  onNextMonthClick: PropTypes.func,

Internationalization:

While we have reasonable defaults for english, we understand that that's not the only language in the world! :) At Airbnb, more than 50% of users visit our site in a language other than english. Thus, in addition to supporting moment locales, the DateRangePicker accepts a number of props to allow for this.

The displayFormat prop is either a string that abides by moment's date formatting rules or a function that returns a string that follows these rules. It defaults to the value of moment's L format in whatever locale you happen to be in at the time of render.

  displayFormat: PropTypes.oneOfType([PropTypes.string, PropTypes.func])

The monthFormat prop abides by moment's date formatting rules and indicates the format in which to display dates at the top of each calendar. It defaults to MMMM YYYY.

  monthFormat: PropTypes.string,

The phrases prop is an object that contains all the English language phrases currently part of the class. As of now, we only have two such phrases and neither are visible but they are used for screen-reader navigation of the datepicker.

  phrases: PropTypes.shape({
    closeDatePicker: PropTypes.node,
    clearDates: PropTypes.node,
  }),

Display picker when clicked on clear button:

The reopenPickerOnClearDates helps to control whether to show the date picker when the clear option is clicked. This is set to false by default which means that the picker does not open when the clear button is clicked by default. To display the picker one must explicitly set it to true.

    reopenPickerOnClearDates: PropTypes.bool

`SingleDatePicker`

This fully-controlled component is designed to allow a user to select a single date.

`Props`

Dates:

Moment objects representing the currently selected date. This is set to null when no date has yet been selected.

  date: momentPropTypes.momentObj

onDateChange is the callback necessary to update the date state held in the parent component. It expects a single argument equal to either null or a moment object.

  onDateChange: PropTypes.func

Focus:

A boolean representing whether or not the date input is currently focused.

  focused: PropTypes.bool

onFocusChange is the callback necessary to update the focus state in the parent component. It expects a single argument of the form { focused: PropTypes.bool }.

  onFocusChange: PropTypes.func

Date selection rules:

These properties are the same as provided to the <DateRangePicker /> component.

To indicate which days are blocked from selection, you may either provide an array of moment objects to the blockedDates prop or you may set blockedByDefault to true and provide available days as an array of moment objects to the unblockedDates prop, depending on what makes sense for you.

  blockedDates: PropTypes.arrayOf(momentPropTypes.momentObj)
  blockedByDefault: PropTypes.bool
  unblockedDates: PropTypes.arrayOf(momentPropTypes.momentObj)

  isOutsideRange: PropTypes.func

Calendar presentation:

These properties are the same as provided to the <DateRangePicker /> component.

numberOfMonths indicates the number of visible months at a time.

  numberOfMonths: PropTypes.number

  enableOutsideDays: PropTypes.bool

DayPicker presentation:

These properties are the same as provided to the <DateRangePicker /> component.

  orientation: PropTypes.oneOf([HORIZONTAL_ORIENTATION, VERTICAL_ORIENTATION])

  withPortal: PropTypes.bool

  withFullScreenPortal: PropTypes.bool

Input presentation:

The id prop is assigned to the actual <input> DOM element. It is currently required for accessibility reasons.

  id: PropTypes.string.isRequired

The placeholder props is the placeholder text for the input. It is both applied as an actual placeholder to the DOM <input> and as a placeholder for the display text. As of v1.0.0, it is also used as label text.

  placeholder: PropTypes.string

Some useful callbacks:

These properties are the same as provided to the <DateRangePicker /> component.

If you need to do something when the user navigates between months (for instance, check the availability of a listing), you can do so using the onPrevMonthClick and onNextMonthClick props.

  onPrevMonthClick: PropTypes.func
  onNextMonthClick: PropTypes.func

Internationalization:

  displayFormat: PropTypes.oneOfType([PropTypes.string, PropTypes.func])

The monthFormat prop abides by moment's date formatting rules and indicates the format in which to display dates at the top of each calendar. It defaults to MMMM YYYY.

  monthFormat: PropTypes.string

The phrases prop is an object that contains all the English language phrases currently part of the class. As of v1.0.0, we only have one such phrases and it is not visible but is used for screen-reader navigation of the datepicker.

  phrases: PropTypes.shape({
    closeDatePicker: PropTypes.node,
  })

`DayPicker`

This fully-controlled component renders a designated number of months and allows for user interaction with days. It is possible to navigate between months using this component.

`Props`

Calendar Presentation:

These properties are the same as provided to the <DateRangePicker /> and <SingleDatePicker /> components.

numberOfMonths indicates the number of visible months at a time.

  numberOfMonths: PropTypes.number

  enableOutsideDays: PropTypes.bool

DayPicker Presentation:

  orientation: PropTypes.oneOf([HORIZONTAL_ORIENTATION, VERTICAL_ORIENTATION]),

withPortal exists primarily for use in conjunction with the <DateRangePicker /> and <SingleDatePicker /> components. It will not do much if a DayPicker is rendered on its own with it set to true other than modify some position-related styles and remove a box-shadow.

  withPortal: PropTypes.bool,

The modifiers object maps modifier names (designated as strings) to functions that take in a moment object and return a boolean value. An example of a modifiers object could be as follows:

  modifiers={{
    friday: (day) => moment.weekdays(day.weekday()) === 'Friday',
  }}

Then, every Friday in the visible calendar would have the class CalendarMonth__day--friday applied to it and could be styled appropriately. By default, the only modifier that is always applied is the outside modifier which is applied to dates on the calendar that might still be visible but fall outside of the current month.

  modifiers: PropTypes.object,

Day interaction callbacks:

These callbacks get triggered when the relevant event ('click', 'mousedown', etc.) occurs on any visible CalendarDay component. The callback gets back 3 arguments, the day represented as a moment object, an array of strings representing the modifiers that are applicable to that day, and the event object itself.

onDayTouchTap has been implemented in-house and has not yet been thoroughly tested. We recommend using onDayClick whenever possible.

  onDayClick: PropTypes.func,
  onDayMouseDown: PropTypes.func,
  onDayMouseUp: PropTypes.func,
  onDayMouseEnter: PropTypes.func,
  onDayMouseLeave: PropTypes.func,
  onDayTouchStart: PropTypes.func,
  onDayTouchEnd: PropTypes.func,
  onDayTouchTap: PropTypes.func,

Some other useful callbacks:

If you need to do something when the user navigates between months (for instance, check the availability of a listing), you can do so using the onPrevMonthClick and onNextMonthClick props.

  onPrevMonthClick: PropTypes.func,
  onNextMonthClick: PropTypes.func,

If you need to do something when the user clicks outside of the DayPicker (for instance, hide the DayPicker), you may do so using the onOutsideClick prop.

  onOutsideClick: PropTypes.func,

Internationalization:

The monthFormat prop abides by moment's date formatting rules and indicates the format in which to display dates at the top of each calendar. It defaults to MMMM YYYY.

  monthFormat: PropTypes.string,

Utility Methods

Date Comparison

We provide four utility methods for date comparison:

  isInclusivelyAfterDay
  isInclusivelyBeforeDay
  isNextDay
  isSameDay

Each of these methods takes in two moment objects and returns a boolean, indicating whether the first argument is inclusively after, inclusively before, the day immediately after, or the same day as the second argument.

Theming

react-dates comes with a set of SCSS variables that can be overridden to add your own project-specific theming. Override any variables found in css/variables.scss with your own and then import ~react-dates/css/styles.scss (and ~react-dates/css/variables.scss if you're only overriding a few). If you were using sass-loader with webpack, the code below would properly override the selected variables:

//overriding default sass variables with my project's colors
$react-dates-color-primary: $some-color-specific-to-my-project;
$react-dates-color-primary-dark: $some-other-color-specific-to-my-project;
@import '~react-dates/css/variables.scss';
@import '~react-dates/css/styles.scss';
