svelte-calendar

A small date picker built with Svelte 3. Demo available here: demo page.

Basic usage

<Datepicker start={minDate} end={maxDate} />

Props

prop name	type	default
start	date	new Date(1987, 9, 29)
end	date	new Date(2020, 9, 29)
selected	date	today
formattedSelected	string	today
dateChosen	boolean	false
selectableCallback	function	null
format	string | function	'#{m}/#{d}/#{Y}'
daysOfWeek	array	En-US Locale (see below)
monthsOfYear	array	En-US Locale (see below)
style	string	""

start and end

These properties set the minimum and maximum dates that will be rendered by this calendar. It is highly recommended that you do not leave these as their defaults and supply values which suit your application's needs.

selected and formattedSelected

Bind to these properties to observe the selected date as either a date or a string. Use selected to set the day which is selected by default.

dateChosen

Bind to this property to observe whether a user has selected a day.

selectableCallback

Provide a function which accepts a date and returns a boolean determining whether a day between start and end is selectable. For example, use this to prevent weekend days from being selected.

format

Date formatting uses timeUtils formatting (MM/DD/YYYY by default). If you would like to use a different formatting library, supply a function which accepts a date and returns a string.

daysOfWeek and monthsOfYear

These two props are used to internationalize the calendar. The default values are:

export let daysOfWeek = [
  ['Sunday', 'Sun'],
  ['Monday', 'Mon'],
  ['Tuesday', 'Tue'],
  ['Wednesday', 'Wed'],
  ['Thursday', 'Thu'],
  ['Friday', 'Fri'],
  ['Saturday', 'Sat']
];
export let monthsOfYear = [
  ['January', 'Jan'],
  ['February', 'Feb'],
  ['March', 'Mar'],
  ['April', 'Apr'],
  ['May', 'May'],
  ['June', 'Jun'],
  ['July', 'Jul'],
  ['August', 'Aug'],
  ['September', 'Sep'],
  ['October', 'Oct'],
  ['November', 'Nov'],
  ['December', 'Dec']
];

style

This prop allows you to style the div which wraps the Datepicker component. This can be useful, for instance, if you'd like to do something like make the component full-width or display: block; (by default the element is inline-block). If you would like to style the button that triggers the opening of the datepicker we recommend you pass a custom element (button/link/etc) to the component via its default slot.

Kitchen Sink Example:

<script>
  const daysOfWeek = [
    [ 'Domingo', 'Dom' ],
    [ 'Lunes', 'Lun' ],
    [ 'Martes', 'Mar' ],
    [ 'Miércoles', 'Mié' ],
    [ 'Jueves', 'Jue' ],
    [ 'Viernes', 'Vie' ],
    [ 'Sábado', 'Sáb' ],
  ];
  const monthsOfYear = [
    [ 'Enero', 'Ene' ],
    [ 'Febrero', 'Feb' ],
    [ 'Marzo', 'Mar' ],
    [ 'Abril', 'Abr' ],
    [ 'Mayo', 'May' ],
    [ 'Junio', 'Jun' ],
    [ 'Julio', 'Jul' ],
    [ 'Agosto', 'Ago' ],
    [ 'Septiembre', 'Sep' ],
    [ 'Octubre', 'Oct' ],
    [ 'Noviembre', 'Nov' ],
    [ 'Diciembre', 'Dic' ],
  ];
</script>

<Datepicker
  bind:formattedSelected={selectedDateFormatted}
  bind:selected={selectedDate}
  bind:dateChosen={userHasChosenDate}
  start={threeDaysInPast}
  end={inThirtyDays}
  selectableCallback={filterWeekends}
  daysOfWeek={daysOfWeek}
  monthsOfYear={monthsOfYear}
  format={date => dayjs(date).format('DD/MM/YYYY')}
/>
