如何将 vue3-openlayers 插件添加到 nuxt

Question

我在Vue3中有以下 main.ts 文件：

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");

如何将 vue3-openlayers 插件添加到nuxt3 ？

Answer 1

要在 Nuxt 3 中自动安装 Vue 插件，请使用以下样板在<projectDir>/plugins/下创建一个.js/.ts文件（如果需要，创建目录）：

// plugins/my-plugin.js
import { defineNuxtPlugin } from '#app'

export default defineNuxtPlugin(nuxtApp => {
  nuxtApp.vueApp.use(/* MyPlugin */)
})

由于vue3-openlayers依赖于window ，插件只能安装在客户端，所以使用.client.js扩展名。

要加载vue3-openlayers客户端， plugin文件如下所示：

// plugins/vue3-openlayers.client.js
import { defineNuxtPlugin } from '#app'
import OpenLayers from 'vue3-openlayers'

export default defineNuxtPlugin(nuxtApp => {
  nuxtApp.vueApp.use(OpenLayers)
})

使用vue3-openlayers文档中的以下示例内容创建<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>组件作为包装器：

// app.vue
<template>
  <ClientOnly>
    <MyMap />
    <template #fallback> Loading map... </template>
  </ClientOnly>
</template>
