到auto-install a Vue plugin in Nuxt 3,在<projectDir>/plugins/ 下创建一个.js/.ts 文件(如果需要,创建目录)并使用以下样板:
// plugins/my-plugin.js
import { defineNuxtPlugin } from '#app'
export default defineNuxtPlugin(nuxtApp => {
nuxtApp.vueApp.use(/* MyPlugin */)
})
由于vue3-openlayers依赖window,插件只能安装在客户端,所以使用.client.js扩展。
要加载vue3-openlayers 客户端,plugin 文件将如下所示:
// plugins/vue3-openlayers.client.js
import { defineNuxtPlugin } from '#app'
import OpenLayers from 'vue3-openlayers'
export default defineNuxtPlugin(nuxtApp => {
nuxtApp.vueApp.use(OpenLayers)
})
使用以下example content from the vue3-openlayers docs 创建<projectDir>/components/MyMap.vue:
// components/MyMap.vue
<script setup>
import { ref } from 'vue'
const center = ref([40, 40])
const projection = ref('EPSG:4326')
const zoom = ref(8)
const rotation = ref(0)
</script>
<template>
<ol-map :loadTilesWhileAnimating="true" :loadTilesWhileInteracting="true" style="height:400px">
<ol-view :center="center" :rotation="rotation" :zoom="zoom"
:projection="projection" />
<ol-tile-layer>
<ol-source-osm />
</ol-tile-layer>
</ol-map>
</template>
<style scoped>
@import 'vue3-openlayers/dist/vue3-openlayers.css';
</style>
我们只想在客户端渲染MyMap,因为插件只是客户端,所以使用<ClientOnly> component作为包装器:
// app.vue
<template>
<ClientOnly>
<MyMap />
<template #fallback> Loading map... </template>
</ClientOnly>
</template>
