vue3-openlayers

Appearance

ol-map ​

The core component of vue3-openlayers

This is the main container for all other vue3-openlayers components and has one default slot to place them all. Usually you will use it together with ol-view component to setup zoom, center, projection and other view related propeties for the map.

Usage ​

Example of a simple map. See also documentation of ol-view component.

vue
<template>
  <ol-map
    :loadTilesWhileAnimating="true"
    :loadTilesWhileInteracting="true"
    style="height: 400px"
  >
    <ol-view
      ref="view"
      :center="center"
      :rotation="rotation"
      :zoom="zoom"
      :projection="projection"
    />

    <ol-tile-layer>
      <ol-source-osm />
    </ol-tile-layer>
  </ol-map>
</template>

<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
      ref="view"
      :center="center"
      :rotation="rotation"
      :zoom="zoom"
      :projection="projection"
    />

    <ol-tile-layer>
      <ol-source-osm />
    </ol-tile-layer>
  </ol-map>
</template>

<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>

Props from OpenLayers ​

Properties are passed-trough from OpenLayers directly. Their types and default values can be checked-out in the official OpenLayers docs. Only some properties deviate caused by reserved keywords from Vue / HTML. This deviating props are described in the section below.

Deviating Properties ​

None.

Events ​

You have access to all Events from the underlying source. Check out the official OpenLayers docs to see the available events tht will be fired.

html
<ol-map @error="handleEvent">
  <!-- ... -->
</ol-map>
<ol-map @error="handleEvent">
  <!-- ... -->
</ol-map>

Methods ​

You have access to all Methods from the underlying source. Check out the official OpenLayers docs to see the available methods.

To access the source, you can use a ref() as shown below:

vue
<template>
  <!-- ... -->
  <ol-map ref="mapRef" @error="handleEvent">
    <!-- ... -->
  </ol-map>
  <!-- ... -->
</template>

<script setup lang="ts">
import { ref, onMounted } from "vue";
import type Map from "ol/Map";

const mapRef = ref<{ map: Map }>(null);

onMounted(() => {
  const map: Map = mapRef.value?.map;
  // call your method on `map`
});
</script>
<template>
  <!-- ... -->
  <ol-map ref="mapRef" @error="handleEvent">
    <!-- ... -->
  </ol-map>
  <!-- ... -->
</template>

<script setup lang="ts">
import { ref, onMounted } from "vue";
import type Map from "ol/Map";

const mapRef = ref<{ map: Map }>(null);

onMounted(() => {
  const map: Map = mapRef.value?.map;
  // call your method on `map`
});
</script>
