/**
 * 一、推荐🔥全局js方式引入
 */
import Vue from 'vue'
import { showImages } from 'vue-img-viewr'
import 'vue-img-viewr/styles/index.css'

const app = createApp(App)
app.config.globalProperties.$showImages = showImages
app.mount('#app')

/** 使用 **/
const appContext = getCurrentInstance()?.appContext as AppContext
const showImagesByJs: (i: number) => void = i => {
  appContext.config.globalProperties.$showImages({
    urls: images,
    index: i,
    onSwitch: (i: number) => void = i => {
      console.log(`current image index: ${i}`)
    },
    onClose: () => {
      console.log('closed')
    }
  })
}

/** 
 * 注册全局组件
 */
import ImgViewr from 'vue-img-viewr'
import 'vue-img-viewr/styles/index.css'

const app = createApp(App)

// 等同于
// app.component('ImgViewr', ImgViewr)
// app.config.globalProperties.$showImages = showImages
app.use(ImgViewr)

app.mount('#app')

/**
 * 二、按需引入使用
 */
// lang="ts"
import { ref } from 'vue'
import ImgViewr, { showImages } from 'vue-img-viewr'
import 'vue-img-viewr/styles/index.css'

const images = [
  'https://s.gravatar.com/avatar/221f86a573320174bad7a62886a6d4b4?size=100&default=retro',

]
export default {
  name: 'App',
  components: { ImgViewr },
  setup () {
    const urls = ref(images)
    const index = ref(0)
    const visible = ref(false)
    const showImagesByComponent: (i: number) => void = i => {
      visible.value = true
      index.value = i
    }
    const showImagesByJs: (i: number) => void = i => {
      showImages({
        urls: images,
        index: i,
        onSwitch: changeHandle,
        onClose: () => {
          console.log('closed js')
        }
      })
    }
    const changeHandle: (i: number) => void = i => {
      console.log(`current image index: ${i}`)
    }
    const closeHandle = () => {
      console.log('closed component')
      visible.value = false
    }
    return {
      urls,
      index,
      visible,
      showImagesByComponent,
      showImagesByJs,
      closeHandle,
      changeHandle
    }
  }

服务端渲染(SSR)中使用,以Nuxtjs为例
