Date Picker Svelte

Date and time picker for Svelte

This is an adaptation from date-picker-svelte.

• Expanding closeOnSelection to be an object so user can choose which actions to close on (day, month, year)
• Expanding on:change event to be an object that includes the date and which field was just change (day, month, year)
• Updating on:change to fire on every change that happens in the picker (the original version did not fire change on year and month changes)

Goes to original packages demo:
Demo • Documentation • REPL

Install

npm i @gregg-cbs/svelte-date-picker

Usage

<script>
  import { DateInput, DatePicker } from 'date-picker-svelte'

  let date = new Date()

  const minDate = new Date()
  minDate.setFullYear(2020)

  const maxDate = new Date()
  maxDate.setFullYear(2026)

  function onChange(e) {
    date = e.detail.value; // value is always a date
    // e.detail.changed tells you whether day, month or year was changed so you can
    // have side effects on these actions if you want
  }
</script>

<!-- input that shows datepicker when clicked on (wraps the DatePicker for you) -->
<DateInput 
  bind:value={date} 
/>
  
<!-- 
DateInput Props

/** Format string */
format = 'yyyy-MM-dd HH:mm:ss' 

/** Locale object for internationalization */
locale: Locale = {}

/** Whether the date popup is visible */
visible = false

/** Close the date popup when a date is selected */
closeOnSelection: {
  day?: boolean,
  month?: boolean,
  year?: boolean
}

/** Wait with updating the date until a date is selected */
browseWithoutSelecting = false

/** Show a time picker with the specified precision */
timePrecision: 'minute' | 'second' | 'millisecond' | null = null

/** Automatically adjust date popup position to not appear outside the screen */
dynamicPositioning = false
-->

<!-- standalone date picker/calendar so you can do your own thing -->
<DatePicker 
  value={value}
  min={minDate}
  max={maxDate}
  on:change={onChange}
/>

<!-- 
  DatePicker Props

	/** Date value. It's `null` if no date is selected */

  /** Locale object for internationalization */

<DatePicker
