[Swiper4](http://www.swiper.com.cn) component for Vue, support pc and mobile, SPA and SSR.

基于 [Swiper4](http://www.swiper.com.cn)、适用于 Vue 的轮播组件，支持服务端渲染和单页应用。

#### NPM

```

### Mount

#### mount with global

``` javascript
import Vue from 'vue'
import VueAwesomeSwiper from '@keepi/swiper'

// require styles
import 'swiper/dist/css/swiper.css'

Vue.use(VueAwesomeSwiper, /* { default global options } */)
```

#### mount with component

```javascript
// require styles
import 'swiper/dist/css/swiper.css'

import { swiper, swiperSlide } from '@keepi/swiper'

export default {
  components: {
    swiper,
    swiperSlide
  }
}
```

#### mount with ssr

```javascript
// If used in nuxt.js/ssr, you should keep it only in browser build environment
if (process.browser) {
  const VueAwesomeSwiper = require('@keepi/swiper/dist/ssr')
  Vue.use(VueAwesomeSwiper)
}
```

#### custom swiper plugin

```javascript
import Swiper from 'swiper'
Swiper.use({
  name: 'pluginName',
  params: {
    pluginSwitch: false,
  },
  on: {
    init() {
      if (!this.params.pluginSwitch) return
      console.log('init')
    },
    // swiper callback...
  }
})
```


### Difference（使用方法的异同）

**SSR and the only difference in the use of the SPA:**
- SPA worked by the `component`, find swiper instance by `ref attribute`.
- SSR worked by the `directive`, find swiper instance by `directive arg`.
- Other configurations, events are the same.

### SPA

```vue
<!-- The ref attr used to find the swiper instance -->
<template>
  <swiper :options="swiperOption" ref="mySwiper" @someSwiperEvent="callback">
    <!-- slides -->
    <swiper-slide>I'm Slide 1</swiper-slide>
    <swiper-slide>I'm Slide 2</swiper-slide>
    <swiper-slide>I'm Slide 3</swiper-slide>
    <swiper-slide>I'm Slide 4</swiper-slide>
    <swiper-slide>I'm Slide 5</swiper-slide>
    <swiper-slide>I'm Slide 6</swiper-slide>
    <swiper-slide>I'm Slide 7</swiper-slide>
    <!-- Optional controls -->
    <div class="swiper-pagination"  slot="pagination"></div>
    <div class="swiper-button-prev" slot="button-prev"></div>
    <div class="swiper-button-next" slot="button-next"></div>
    <div class="swiper-scrollbar"   slot="scrollbar"></div>
  </swiper>
</template>

<script>
  export default {
    name: 'carrousel',
    data() {
      return {
        swiperOption: {
          // some swiper options/callbacks
          // 所有的参数同 swiper 官方 api 参数
          // ...
        }
      }
    },
    computed: {
      swiper() {
        return this.$refs.mySwiper.swiper
      }
    },
    mounted() {
      // current swiper instance
      // 然后你就可以使用当前上下文内的swiper对象去做你想做的事了
      console.log('this is current swiper instance object', this.swiper)
      this.swiper.slideTo(3, 1000, false)
    }
  }
</script>
```

### Async data example

```vue
<template>
  <swiper :options="swiperOption">
    <swiper-slide v-for="(slide, index) in swiperSlides" :key="index">I'm Slide {{ slide }}</swiper-slide>
    <div class="swiper-pagination" slot="pagination"></div>
  </swiper>
</template>

<script>
  export default {
    name: 'carrousel',
    data() {
      return {
        swiperOption: {
          pagination: {
            el: '.swiper-pagination'
          }
        },
        swiperSlides: [1, 2, 3, 4, 5]
      }
    },
    mounted() {
      setInterval(() => {
        console.log('simulate async data')
        if (this.swiperSlides.length < 10) {
          this.swiperSlides.push(this.swiperSlides.length + 1)
        }
      }, 3000)
    }
  }
</script>
```


### SSR

```vue
<!-- You can custom the "mySwiper" name used to find the swiper instance in current component -->
<template>
  <div v-swiper:mySwiper="swiperOption" @someSwiperEvent="callback">
    <div class="swiper-wrapper">
      <div class="swiper-slide" v-for="banner in banners">
        <img :src="banner">
      </div>
    </div>
    <div class="swiper-pagination"></div>
  </div>
</template>

<script>
  export default {
    data () {
      return {
        banners: [ '/1.jpg', '/2.jpg', '/3.jpg' ],
        swiperOption: {
          pagination: {
            el: '.swiper-pagination'
          },
          // some swiper options...
        }
      }
    },
    mounted() {
      setTimeout(() => {
        this.banners.push('/4.jpg')
        console.log('banners update')
      }, 3000)
      console.log(
        'This is current swiper instance object', this.mySwiper, 
        'It will slideTo banners 3')
      this.mySwiper.slideTo(3, 1000, false)
    }
  }
</script>
```
