vue+cesium 项目搭建

Cesium 1.63 版本之前是用的AMD的方式进行编译的，而在1.63版时使用ES6进行了重构，因此网上很多vue配置cesium的项目搭建方法是失败的。通过总结，vue项目初始化之后，根据项目版本，如下修改webpack配置：

配置文件

package.json 内的 cesium和vue版本。webpack和cesium的版本不一样，有可能以下项目配置会失败，此处提供参考，请勿修改你的package配置。

  })

vue组件

<template>
  <div id="app">
    <div id="cesiumContainer"></div>
  </div>
</template>

<script>
import * as Cesium from 'cesium/Cesium'
import 'cesium/Widgets/widgets.css'
export default {
  mounted: function () {
    this.$nextTick(function () {
      let viewer = new Cesium.Viewer('cesiumContainer', {})
      viewer.camera.setView({
        orientation: {
          heading: Cesium.Math.toRadians(0),
          pitch: Cesium.Math.toRadians(-90),
          roll: Cesium.Math.toRadians(0)
        }
      })
    })
  }
}
</script>
<style>
  html,
  body {
    width: 100%;
    height: 100%;
    padding: 0;
    margin: 0;
  }
  #app,#cesiumContainer {
    font-family: "Avenir", Helvetica, Arial, sans-serif;
    width: 100%;
    height: 100%;
    overflow: hidden;
  }
</style>

配置完成后 npm run dev 运行
