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

import {

  Map,
  Layers,
  Sources,
  Styles,
} from "vue3-openlayers";

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

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 Styles.

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.).
