### SveltyPicker Date Binding Example

Source: https://svelty-picker.vercel.app/working-with-dates

This example demonstrates how to bind the `value` property of SveltyPicker using function binding to format and parse dates. It ensures that the internal `date` variable is kept in sync with the picker's selected value.

```svelte
<script>
  import SveltyPicker, { formatDate, parseDate } from 'svelty-picker';
  import { en} from 'svelty-picker/i18n';

	let date = $state((() => {
		let initDate = new Date();
		initDate.setHours(0,0,0);
		return initDate;
	})());
</script>

Selected date: {date}
<SveltyPicker
  mode="date"
  format="yyyy/mm/dd"
  bind:value={
    () => {
      return formatDate(date, 'yyyy/mm/dd', en, 'standard');
    },
    (v) => {
      date = v ? parseDate(v, 'yyyy/mm/dd', en, 'standard') : null;
    }
  }
/>
```

```svelte
<script>
  import SveltyPicker, { formatDate, parseDate } from 'svelty-picker';
  import { en} from 'svelty-picker/i18n';

	let date = $state((() => {
		let initDate = new Date();
		initDate.setHours(0,0,0);
		return initDate;
	})());
</script>

Selected date: {date}
<SveltyPicker
  mode="date"
  format="yyyy/mm/dd"
  bind:value={
    () => {
      return formatDate(date, 'yyyy/mm/dd', en, 'standard');
    },
    (v) => {
      date = v ? parseDate(v, 'yyyy/mm/dd', en, 'standard') : null;
    }
  }
/>
```

### Applying Global and Local Svelty Picker Configurations

Source: https://svelty-picker.vercel.app/global-config

Demonstrates how to set global configuration options for Svelty Picker, such as language and week start day, and how to override these settings for individual picker instances.

```svelte
<script>
	import SveltyPicker, { config } from 'svelty-picker';
	import { de, jp } from 'svelty-picker/i18n';

	// all pickers set to german and to start week on saturday
	config.i18n = de;
	config.weekStart = 6;
</script>

<div style="display:flex;gap:1rem">
	<div>
		<h3>My german picker (global) </h3>
		<SveltyPicker pickerOnly />
	</div>
	<div>
		<h3>Japanese override</h3>
		<SveltyPicker pickerOnly i18n={jp} weekStart={1} />
	</div>
</div>
```

```svelte
<script>
	import SveltyPicker, { config } from 'svelty-picker';
	import { de, jp } from 'svelty-picker/i18n';

	// all pickers set to german and to start week on saturday
	config.i18n = de;
	config.weekStart = 6;
</script>

<div style="display:flex;gap:1rem">
	<div>
		<h3>My german picker (global) </h3>
		<SveltyPicker pickerOnly />
	</div>
	<div>
		<h3>Japanese override</h3>
		<SveltyPicker pickerOnly i18n={jp} weekStart={1} />
	</div>
</div>
```

### Svelty Picker Component Examples

Source: https://svelty-picker.vercel.app/modes-and-formats

Demonstrates different configurations of the SveltyPicker component, including matching and differing format/displayFormat properties, and a time-only format.

```svelte
<div class="flex">
	<div>
		<div>
			Format === displayFormat<br>Internal value: <code>{valueDefault}</code>
		</div>
		<SveltyPicker bind:value={valueDefault}/>
	</div>
	<div>
		<div>
			Format !== displayFormat<br>Internal value: <code>{valueDifferent}</code>
		</div>
		<SveltyPicker bind:value={valueDifferent} displayFormat="j. n. Y" displayFormatType="php"/>
	</div>
	<div>
		<div>
			Time only format:<br>Internal value: <code>{valueTimeOnly}</code>
		</div>
		<SveltyPicker bind:value={valueTimeOnly} format="hh:ii" displayFormat="HH:ii P"/>
	</div>
</div>
```

--------------------------------

### Configure Svelty Picker with German Locale and Saturday Week Start

Source: https://svelty-picker.vercel.app/localization

This snippet demonstrates how to globally configure the Svelty Picker to use the German locale and set the week to start on Saturday. This configuration affects all Svelty Picker instances on the page unless overridden.

```javascript
import SveltyPicker, { config } from 'svelty-picker';
import { de, jp } from 'svelty-picker/i18n';

// all pickers set to german and to start week on saturday
config.i18n = de;
config.weekStart = 6;
```

--------------------------------

### Migrating Events to Callback Properties

Source: https://svelty-picker.vercel.app/migration-guide

Event dispatchers have been replaced by event callback properties. For example, `on:change` is now `onChange`.

```svelte
<SveltyPicker on:change={fetchEventHandler} /> // [!code --]
<SveltyPicker onChange={fetchEventHandler} /> // [!code ++]
```

--------------------------------

    --sdt-shadow-color: #ccc;
    --sdt-color: inherit;
    --sdt-clock-color: var(--sdt-color);
    --sdt-clock-color-hover: var(--sdt-color);

  }
</style>
```

--------------------------------

### Migrating initialDate Property

Source: https://svelty-picker.vercel.app/migration-guide

The `initialDate` property is deprecated in favor of Svelte 5's function bindings. Use `bind:value` directly for more powerful date handling.

```svelte
<SveltyPicker bind:value intialDate={myDate} {...otherProps} />  // [!code --]
<SveltyPicker bind:value {...otherProps} />  // [!code ++]
```

--------------------------------

### Date Helper Functions

Source: https://svelty-picker.vercel.app/working-with-dates

These functions are used for converting between Date objects and strings. They are essential for managing date values, especially when the library expects string inputs.

```javascript
/**
 * String -> date
 *
 * @param {Date|string} date
 * @param {string} format
 * @param {i18nType} i18n
 * @param {string} type
 * @returns {Date}
 */
export function parseDate(date, format, i18n, type) { /* ... */}

/**
 * Date -> string
 *
 * @param {Date} date
 * @param {string} format
 * @param {i18nType} i18n
 * @param {string} type
 * @returns {string}
 */
export function formatDate(date, format, i18n, type) { /* ... */}
```

```javascript
/**
 * String -> date
 *
 * @param {Date|string} date
 * @param {string} format
 * @param {i18nType} i18n
 * @param {string} type
 * @returns {Date}
 */
export function parseDate(date, format, i18n, type) { /* ... */}

/**
 * Date -> string
 *
 * @param {Date} date
 * @param {string} format
 * @param {i18nType} i18n
 * @param {string} type
 * @returns {string}
 */
export function formatDate(date, format, i18n, type) { /* ... */}
```

    --sdt-shadow-color: #777;
    --sdt-color: #eee;
    --sdt-clock-color: var(--sdt-color);
    --sdt-clock-color-hover: var(--sdt-color);

```svelte
<SveltyPicker>
  <svg ... />
</SveltyPicker>
```

```svelte
<SveltyPicker>
  <svg ... />
</SveltyPicker>
```

--------------------------------

### Disabling Dates with startDate and endDate

Source: https://svelty-picker.vercel.app/disabling-dates

Use `startDate` and `endDate` to define an inclusive range of selectable dates. It's recommended to use string formats that match the picker's `format` property.

```javascript
<script>
	import SveltyPicker from 'svelty-picker';

	let startDate = '2024-12-04';
	let endDate = '2024-12-28';

	function disableWeekends(date) {
		return date.getDay() === 0 || date.getDay() === 6
	}
</script>

<SveltyPicker {startDate} {endDate} placeholder="Only December is allowed"/>

<SveltyPicker disableDatesFn={disableWeekends} placeholder="Weekends are disabled"/>

```
