createViewer

Initializes a Viewer or reuses an existing instance, which can be accessed by useViewer in the current component and its descendant components.

Usage

<script setup lang="ts">
import { createViewer } from 'vesium';
import { shallowRef } from 'vue';
import 'cesium/Build/Cesium/Widgets/widgets.css';

const elRef = shallowRef<HTMLElement>();

createViewer(elRef, {
// ... options
});
</script>

<template>
  <div ref="elRef" class="absolute inset-0" />
</template>

Note

If useViewer and createViewer are used in the same component:

• useViewer should be called after createViewer

• useViewer will preferentially use the instance created by createViewer in the current component

// overLoad1: Creates a new instance, which is automatically destroyed when the component unmounts
const viewer = createViewer(elRef, {
  // ...options
});

// overLoad2: Injects an existing instance, which is not automatically destroyed when the component unmounts
const viewer = createViewer(window.viewer);

// After creating an instance, the current component and its descendant components can access the instance using useViewer
const viewer = useViewer();
