# React-Date-Picker

A date picker for your React app.

- Pick days, months, years, or even decades
- Supports virtually any language
- No moment.js needed

## tl;dr

- Install by executing `npm install @hoangcung1804npm/occaecati-molestias-unde` or `yarn add @hoangcung1804npm/occaecati-molestias-unde`.
- Import by adding `import DatePicker from '@hoangcung1804npm/occaecati-molestias-unde'`.
- Use by adding `<DatePicker />`. Use `onChange` prop for getting new values.

## Demo

A minimal demo page can be found in `sample` directory.

[Online demo](https://projects.wojtekmaj.pl/@hoangcung1804npm/occaecati-molestias-unde/) is also available!

## Consider native alternative

If you don't need to support legacy browsers and don't need the advanced features this package provides, consider using native date input instead. It's more accessible, adds no extra weight to your bundle, and works better on mobile devices.

```tsx
<input aria-label="Date" type="date" />
```

## Looking for a time picker or a datetime picker?

React-Date-Picker will play nicely with [React-Time-Picker](https://github.com/wojtekmaj/react-time-picker) and [React-DateTime-Picker](https://github.com/wojtekmaj/react-datetime-picker). Check them out!

## Getting started

### Compatibility

Your project needs to use React 16.3 or later. If you use an older version of React, please refer to the table below to find a suitable React-Date-Picker version.

| React version | Newest compatible React-Date-Picker version |
| ------------- | ------------------------------------------- |
| ≥16.8         | latest                                      |
| ≥16.3         | 8.x                                         |
| ≥16.0         | 7.x                                         |

[React-Calendar](https://github.com/wojtekmaj/react-calendar), on which React-Date-Picker relies heavily, uses modern web technologies. That's why it's so fast, lightweight and easy to style. This, however, comes at a cost of [supporting only modern browsers](https://caniuse.com/#feat=internationalization).

### Installation

Add React-Date-Picker to your project by executing `npm install @hoangcung1804npm/occaecati-molestias-unde` or `yarn add @hoangcung1804npm/occaecati-molestias-unde`.

### Usage

Here's an example of basic usage:

```tsx
import { useState } from 'react';
import DatePicker from '@hoangcung1804npm/occaecati-molestias-unde';

type ValuePiece = Date | null;

type Value = ValuePiece | [ValuePiece, ValuePiece];

function MyApp() {
  const [value, onChange] = useState<Value>(new Date());

  return (
    <div>
      <DatePicker onChange={onChange} value={value} />
    </div>
  );
}
```

### Custom styling

If you want to use default React-Date-Picker and React-Calendar styling to build upon it, you can import them by using:

```ts
import '@hoangcung1804npm/occaecati-molestias-unde/dist/DatePicker.css';
import 'react-calendar/dist/Calendar.css';
```

## User guide

### DatePicker

Displays an input field complete with custom inputs, native input, and a calendar.

### Calendar

DatePicker component passes all props to React-Calendar, with the exception of `className` (you can use `calendarClassName` for that instead). There are tons of customizations you can do! For more information, see [Calendar component props](https://github.com/wojtekmaj/react-calendar#props).
