A date library agnostic React component for choosing dates and date ranges. Uses [date-fns](http://date-fns.org/) for date operations.

### Why should you use `react-date-range`?

- Stateless date operations
- Highly configurable
- Multiple range selection
- Based on native js dates
- Drag n Drop selection
- Keyboard friendly

## Getting Started
### Installation

```
npm install --save react-date-range
```
This plugin expects `react` and `date-fns` as peerDependencies, It means that you need to install them in your project folder.

```
npm install --save react date-fns
```

## Usage

You need to import skeleton and theme styles first.

```javascript
import 'react-date-range/dist/styles.css'; // main style file
import 'react-date-range/dist/theme/default.css'; // theme css file
```

### `DatePicker`
```javascript
import { Calendar } from 'react-date-range';

class MyComponent extends Component {
  handleSelect(date){
    console.log(date); // native Date object
  }
  render(){
    return (
      <Calendar
        date={new Date()}
        onChange={this.handleSelect}
      />
    )
  }
}

```

### `DateRangePicker / DateRange`
```javascript
import { DateRangePicker } from 'react-date-range';

class MyComponent extends Component {
  handleSelect(ranges){
    console.log(ranges);
    // {
    //   selection: {
    //     startDate: [native Date Object],
    //     endDate: [native Date Object],
    //   }
    // }
  }
  render(){
    const selectionRange = {
      startDate: new Date(),
      endDate: new Date(),
      key: 'selection',
    }
    return (
      <DateRangePicker
        ranges={[selectionRange]}
        onChange={this.handleSelect}
      />
    )
  }
}

```

 *shape of range:
 ```js
  {
    startDate: PropTypes.object,
    endDate: PropTypes.object,
    color: PropTypes.string,
    key: PropTypes.string,
    autoFocus: PropTypes.bool,
    disabled: PropTypes.bool,
    showDateDisplay: PropTypes.bool,
  }
```

 **shape of ariaLabels:
 ```js
  {
    // The key of dateInput should be same as key in range.
    dateInput: PropTypes.objectOf(
      PropTypes.shape({
        startDate: PropTypes.string,
        endDate: PropTypes.string
      })
    ),
    monthPicker: PropTypes.string,
    yearPicker: PropTypes.string,
    prevButton: PropTypes.string,
    nextButton: PropTypes.string,
  }
```
#### Infinite Scrolled Mode

To enable infinite scroll set `scroll={{enabled: true}}` basically. Infinite scroll feature is affected by `direction`(rendering direction for months) and `months`(for rendered months count) props directly.
If you prefer, you can overwrite calendar sizes with `calendarWidth`/`calendarHeight` or each month's height/withs with `monthWidth`/`monthHeight`/`longMonthHeight` at `scroll` prop.

```js
  // shape of scroll prop
  scroll: {
    enabled: PropTypes.bool,
    monthHeight: PropTypes.number,
    longMonthHeight: PropTypes.number, // some months has 1 more row than others
    monthWidth: PropTypes.number, // just used when direction="horizontal"
    calendarWidth: PropTypes.number, // defaults monthWidth * months
    calendarHeight: PropTypes.number, // defaults monthHeight * months
  }),
```


### Release workflow
- Merge everything that needs to be in the release to master
- Open a new release PR than:
  - bumps version to appropriate one <new_version>
  - Update CHANGELOG.md
- Make sure the demo and important features are working as expected
- After merging, tag the master commit with `release/<new_version>` and let Github Action handle publishing
- = Profit 🙈

### TODOs

- Make mobile friendly (integrate tap and swipe actions)
- Add tests
- Improve documentation
