我在Vue3 中有以下 main.ts 檔案：
import { createApp } from "vue"
import App from "./App.vue";
//How to do this in nuxt3?
import OpenLayersMap from "vue3-openlayers";
import "vue3-openlayers/dist/vue3-openlayers.css";
const app = createApp(App);
//How to do this in nuxt3?
app.use(OpenLayersMap);
app.mount("#app");
如何將 vue3-openlayers 插件添加到nuxt3？
uj5u.com熱心網友回復：
要在 Nuxt 3 中自動安裝 Vue 插件，請使用以下樣板.js/.ts在<projectDir>/plugins/（如果需要，請創建目錄）下創建一個檔案：
// plugins/my-plugin.js
import { defineNuxtPlugin } from '#app'
export default defineNuxtPlugin(nuxtApp => {
nuxtApp.vueApp.use(/* MyPlugin */)
})
由于vue3-openlayers依賴window，插件只能安裝在客戶端，所以使用.client.js擴展。
要加載vue3-openlayers客戶端，plugin檔案將如下所示：
// plugins/vue3-openlayers.client.js
import { defineNuxtPlugin } from '#app'
import OpenLayers from 'vue3-openlayers'
export default defineNuxtPlugin(nuxtApp => {
nuxtApp.vueApp.use(OpenLayers)
})
<projectDir>/components/MyMap.vue使用檔案中的以下示例內容vue3-openlayers創建：
// 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>
我們只想MyMap在客戶端渲染，因為插件只是客戶端，所以使用<ClientOnly>組件作為包裝器：
// app.vue
<template>
<ClientOnly>
<MyMap />
<template #fallback> Loading map... </template>
</ClientOnly>
</template>
