## Install

```bash
$ npm install vue2-datepicker --save
```

## Usage

```html
<script>
  import DatePicker from 'vue2-datepicker';
  import 'vue2-datepicker/index.css';

  export default {
    components: { DatePicker },
    data() {
      return {
        time1: null,
        time2: null,
        time3: null,
      };
    },
  };
</script>

<template>
  <div>
    <date-picker v-model="time1" valueType="format"></date-picker>
    <date-picker v-model="time2" type="datetime"></date-picker>
    <date-picker v-model="time3" range></date-picker>
  </div>
</template>
```

## Theme

If your project uses SCSS, you can change the default style variables.

To create a scss file. e.g. `datepicker.scss`:

```scss
$default-color: #555;
$primary-color: #1284e7;

@import '~vue2-datepicker/scss/index.scss';
```

## Internationalization

The default language of v3.x is English. If you need other locales.
You can import locale file.
Once you import a locale, it becomes the active locale.

```js
import DatePicker from 'vue2-datepicker';
import 'vue2-datepicker/index.css';

import 'vue2-datepicker/locale/zh-cn';
```

You can also override some of the default locale by `lang`.
[Full config](https://github.com/mengxiong10/vue2-datepicker/blob/master/locale.md)

```html
<script>
  export default {
    data() {
      return {
        lang: {
          formatLocale: {
            firstDayOfWeek: 1,
          },
          monthBeforeYear: false,
        },
      };
    },
  };
</script>

<template>
  <date-picker :lang="lang"></date-picker>
</template>
```
