## Installation
```Bash
yarn add @reecelucas/react-datepicker
```
## Example Usage
### Basic
```jsx
console.log(date)}>
prev()}>
Prev Month
next()}>
Next Month
```
### Initial Date
```jsx
console.log(date)}
>
{/* ... */}
```
### Min Date
```jsx
console.log(date)}
>
{/* ... */}
```
### Max Date
```jsx
console.log(date)}
>
{/* ... */}
```
### Date Range
```jsx
console.log(date)}
>
{/* ... */}
```
### Exclude Dates
```jsx
console.log(date)}
>
{/* ... */}
```
### Include Dates
```jsx
console.log(date)}
>
{/* ... */}
```
### Non-English Locale
Import the required date-fns [`locale`](https://date-fns.org/v2.0.0-alpha.37/docs/I18n#supported-languages)
and make sure to render a custom aria label for each day, using the `renderDayLabel` prop.
```jsx
import { format } from 'date-fns';
import locale from 'date-fns/locale/fr';
console.log(date)}
>
{/* ... */}
{/* ... */}
{
const status = isSelected ? 'Sélectionné. ' : `${isSelectable ? 'Disponible. ' : 'Indisponible. '}`;
return `${status}${format(date, 'eeee, do MMMM yyyy', { locale })}.`;
}}
/>
```
### Custom Month Format
Pass a valid date-fns [`format`](https://date-fns.org/v2.0.0-alpha.37/docs/format) string.
```jsx
console.log(date)}>
{/* ... */}
```
### Render Day Content
```jsx
import { getDate, isWeekend } from 'date-fns';
console.log(date)}>
{/* ... */}
{/* ... */}
(
{getDate(date)}
)}
/>
```
### Custom Input Date Format
Pass a valid date-fns [`format`](https://date-fns.org/v2.0.0-alpha.37/docs/format) string.
```jsx
console.log(date)}>
{/* ... */}
```
### Custom Screen Reader Message
The `DatePickerInput` includes an `aria-describedby` attribute that references
a visually hidden aria message (for use by screen readers). The default message is:
```jsx
<>
Press the down arrow key to interact with the calendar and select a date.
The following keyboard shortcuts can be used to change dates.
- Enter Key: select the date in focus.
-
Right and left arrow keys: Move backward (left) and forward (right) by
one day.
-
Up and down arrow keys: Move backward (up) and forward (down) by one
week.
- Page up and page down keys: Switch months.
- Home and end keys: go to the first or last day of a week.
- Escape key: Return to the date input field.
```
But you can render a custom message (E.g. written in another language if you're
passing a [`locale`](#non-english-locale)) by passing a render function...
```jsx
const renderScreenReaderMsg = () => (
I'm a custom screen reader message. I should describe how to interact with
the date picker, playing special attention to the keyboard shortcuts that
are available. This message won't be visible in the UI.
);
console.log(date)}>
{/* ... */}
```
...Or by passing a JSX element
```jsx
console.log(date)}>
I'm a custom screen reader message. I should describe how to interact with
the date picker, playing special attention to the keyboard shortcuts that
are available. This message won't be visible in the UI.
}
/>
{/* ... */}
```
