Setup

Plugin usage

This component is part of the Animations 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 Animations plugin

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

import {

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

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

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 Animations.

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.).
