I have the following main.ts file in Vue3:
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");
How can I add the vue3-openlayers plugin to nuxt3?
To auto-install a Vue plugin in Nuxt 3, create a .js/.ts file under <projectDir>/plugins/ (create the directory if needed) with the following boilerplate:
// plugins/my-plugin.js
import { defineNuxtPlugin } from '#app'
export default defineNuxtPlugin(nuxtApp => {
nuxtApp.vueApp.use(/* MyPlugin */)
})
Since vue3-openlayers depends on window, the plugin can only be installed client side, so use the .client.js extension.
To load vue3-openlayers client side, the plugin file would look like this:
// plugins/vue3-openlayers.client.js
import { defineNuxtPlugin } from '#app'
import OpenLayers from 'vue3-openlayers'
export default defineNuxtPlugin(nuxtApp => {
nuxtApp.vueApp.use(OpenLayers)
})
Create <projectDir>/components/MyMap.vue with the following example content from the vue3-openlayers docs:
// 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>
We only want to render MyMap on the client because the plugin is only client-side, so use the <ClientOnly> component as a wrapper:
// app.vue
<template>
<ClientOnly>
<MyMap />
<template #fallback> Loading map... </template>
</ClientOnly>
</template>
