Setup

Plugin usage

This component is part of the Geometries plugin. If not installed globally, you need to import and use the plugin in your main.ts or use the explicit component import (see section below).

Import and use the Geometries plugin

import { createApp } from "vue";
import App from "./App.vue";

import {
  Map,
  Layers,
  Sources,
  Geometries,
} from "vue3-openlayers";

const app = createApp(App);
// ...
app.use(Geometries); 
// ...

Explicit import

If you don't want to install a plugin, you can import the component explicitly. It's available as a child of the named export Geometries.

NOTE

The following documentation refers to the plugin usage. Please make sure to adopt the component names, when you decided to use explicit component imports (e. g. <ol-map> becomes <Map.OlMap> etc.).
