@darrken/react-datepicker

React Date Picker

A simple and reusable Datepicker component for React, forked from HackerOne's react-datepicker, using the native javascript Date object.

Installation

The package can be installed via NPM:

npm install @darrken/react-datepicker --save

You’ll need to install React and PropTypes separately since those dependencies aren’t included in the package. If you need to use a locale other than the default en-US, you'll also need to import that into your project from date-fns (see Localization section below). Below is a simple example of how to use the Datepicker in a React view. You will also need to require the CSS file from this package (or provide your own). The example below shows how to include the CSS from this package if your build system supports requiring CSS files (Webpack is one that does).

import React from 'react';
import DatePicker from '@darrken/react-datepicker';

import '@darrken/react-datepicker/dist/react-datepicker.css';

// CSS Modules, react-datepicker-cssmodules.css
// import '@darrken/react-datepicker/dist/react-datepicker-cssmodules.css';

class Example extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      startDate: new Date()
    };
    this.handleChange = this.handleChange.bind(this);
  }

  handleChange(date) {
    this.setState({
      startDate: date
    });
  }

  render() {
    return (
      <DatePicker
        selected={this.state.startDate}
        onChange={this.handleChange}
      />
    );
  }
}

Configuration

The most basic use of the DatePicker can be described with:

<DatePicker selected={this.state.date} onChange={this.handleChange} />

You can use onSelect event handler which fires each time some calendar date has been selected

<DatePicker
  selected={this.state.date}
  onSelect={this.handleSelect} //when day is clicked
  onChange={this.handleChange} //only when value has changed
/>

onClickOutside handler may be useful to close datepicker in inline mode

See here for a full list of props that may be passed to the component. Examples are given on the main website.

Time picker

You can also include a time picker by adding the showTimeSelect prop

<DatePicker
  selected={this.state.date}
  onChange={this.handleChange}
  showTimeSelect
  dateFormat="Pp"
/>

Times will be displayed at 30-minute intervals by default (default configurable via timeInterval prop)

More examples of how to use the time picker are given on the main website

Localization

The date picker relies on date-fns internationalization to localize its display components. By default, the date picker will use the locale globally set, which is English. Provided are 3 helper methods to set the locale:

• registerLocale (string, object): loads an imported locale object from date-fns
• setDefaultLocale (string): sets a registered locale as the default for all datepicker instances
• getDefaultLocale: returns a string showing the currently set default locale

To load an alternate locale:

• Import the helper methods you need: import { registerLocale, setDefaultLocale } from DatePicker;
• Import the locale from date-fns: import fi from 'date-fns/locale/fi';
• Register the locale: registerLocale('fi', fi);

Locales can be changed in the following ways:

• Globally - setDefaultLocale('fi');
• Picker-specific by providing the locale prop - <DatePicker locale='fi' ... />

Compatibility

React

We're always trying to stay compatible with the latest version of React. We can't support all older versions of React.

Latest compatible versions:

• React 15.5 or newer: All above React-datepicker v.0.40.0
• React 15.4.1: needs React-datepicker v0.40.0, newer won't work (due to react-onclickoutside dependencies)
• React 0.14 or newer: All above React-datepicker v0.13.0
• React 0.13: React-datepicker v0.13.0
• pre React 0.13: React-datepicker v0.6.2

Browser Support

The date picker is compatible with the latest versions of Chrome, Firefox, and IE10+.

Unfortunately, it is difficult to support legacy browsers while maintaining our ability to develop new features in the future. For IE9 support, it is known that the classlist polyfill is needed, but this may change or break at any point in the future.

Local Development

The master branch contains the latest version of the Datepicker component. To start your example app, you can run yarn start. This starts a simple webserver on http://localhost:8080.

You can run yarn test to execute the test suite and linters. To help you develop the component we’ve set up some tests that cover the basic functionality (can be found in /tests). Even though we’re big fans of testing, this only covers a small piece of the component. We highly recommend you add tests when you’re adding new functionality.

The examples

The examples are hosted within the docs folder and are ran in the simple app that loads the Datepicker. To extend the examples with a new example, you can simply duplicate one of the existing examples and change the unique properties of your example.
