>A minimal, accessible React/Preact calendar component using modern CSS, for modern browsers. *Now with a 100 Lighthouse Accessibility Audit score.* It works with native Javascript dates, so there's no need to import any heavy dependencies like `moment`. For a set of functions for working with Javascript Dates, we recommend [`date-fns`](https://date-fns.org). For a more flexible, fully-featured set of calendar components, see [`react-dates`](https://github.com/airbnb/react-dates).

## Installation
Using recal is simple. Just install the npm package:

```bash
npm i -S recal
```

Or, import recal and its stylesheet via CDN:

```html

```

## Usage

If you're using recal from npm, be sure to import the necessary modules into the file you wish to use it in.

```javascript
// You can use React or Preact hereβ€”just make sure you have the proper aliasing.
import React from 'react';

// Calendar components.
import { DatePicker, DateRangePicker } from 'recal';

// Stylesheet for calendar.
import 'recal/lib/index.css';
```

### Date Picker

To create a single date picker, use the `DatePicker` component as follows:

```javascript
class MyDatePicker extends React.Component {
state = {};

onDateSelected = (selectedDate) => {
this.setState({
selectedDate
});
}

render() {
return (

);
}
}
```

### Date Range Picker

To create a date range picker, use the `DateRangePicker` component as follows:

```javascript
class MyDateRangePicker extends React.Component {
state = {};

onStartDateSelected = (startDate) => {
this.setState({
startDate
});
}
onEndDateSelected = (endDate) => {
this.setState({
endDate
});
}

render() {
return (

);
}
}
```

### Options

Both calendars have some required and some optional props.

```javascript
// Used by DatePicker
selectedDate: PropTypes.instanceOf(Date),
onDateSelected: PropTypes.func,

// Used by DateRangePicker
startDate: PropTypes.instanceOf(Date),
endDate: PropTypes.instanceOf(Date),
onStartDateSelected: PropTypes.func,
onEndDateSelected: PropTypes.func,

// Used by either (optional)
onDateHovered: PropTypes.func,
onDateFocused: PropTypes.func,
isDateHighlighted: PropTypes.func,
isDateEnabled: PropTypes.func,
locale: PropTypes.string,
disabled: PropTypes.bool
```

## Localization

Use the `locale` string prop on the calendar components to localize the month and days of the week into other languages *(e.g. "en-US", "es-MX", etc.)*.

## Accessibility

This set of calendars are optimized for screen readers as well as for keyboard-based navigation. The following shortcuts are available when the calendar is focused:

| Key | Direction | Time |
| ------------------| ----------| --------|
| Left Arrow | Back | 1 day |
| Right Arrow | Forward | 1 day |
| Up Arrow | Back | 1 week |
| Down Arrow | Forward | 1 week |
| Page Up | Back | 1 month |
| Page Down | Forward | 1 month |
| Shift + Page Up | Back | 1 year |
| Shift + Page Down | Forward | 1 year |
