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
ts
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.).
