一個簡單的 Vue Cli 4 引入 Cesium 的架子，可以直接拉取專案，自己擴充套件。歡迎試用，可以 Star 喲！

Vue 專案搭建，我就不展示了。按照官網直接一步一步進行就可以。也不展示 webpack 配置的坑了，按照下面的程式碼配置，專案就能用。

vue.config.js

const CopyWebpackPlugin = require("copy-webpack-plugin");
const webpack = require("webpack");

module.exports = {
  configureWebpack: {
    plugins: [
      // Copy Cesium Assets, Widgets, and Workers to a static directory
      new CopyWebpackPlugin({
        patterns: [
          { from: "node_modules/cesium/Build/Cesium/Workers", to: "Workers" },
          {
            from: "node_modules/cesium/Build/Cesium/ThirdParty",
            to: "ThirdParty"
          },
          { from: "node_modules/cesium/Build/Cesium/Assets", to: "Assets" },
          { from: "node_modules/cesium/Build/Cesium/Widgets", to: "Widgets" }
        ]
      }),
      new webpack.DefinePlugin({
        // Define relative base path in cesium for loading assets
        CESIUM_BASE_URL: JSON.stringify("")
      })
    ],
    module: {
      // Removes these errors: "Critical dependency: require function is used in a way in which dependencies cannot be statically extracted"
      // https://github.com/AnalyticalGraphicsInc/cesium-webpack-example/issues/6
      unknownContextCritical: false,
      unknownContextRegExp: /\/cesium\/cesium\/Source\/Core\/buildModuleUrl\.js/
    }
  }
};

Map.vue

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

<script>
import "cesium/Build/Cesium/Widgets/widgets.css";
import * as Cesium from "cesium";

export default {
  name: "Map",
  mounted() {
    this.init();
  },
  methods: {
    init() {
      let viewer = new Cesium.Viewer("cesiumContainer");

      let imageryLayers = viewer.imageryLayers;

      let googleMap = new Cesium.UrlTemplateImageryProvider({
        url: "http://www.google.com/maps/vt?lyrs=s@716&x={x}&y={y}&z={z}"
      });

      imageryLayers.addImageryProvider(googleMap);

      // fly
      viewer.camera.flyTo({
        destination: Cesium.Cartesian3.fromDegrees(
          114.296063,
          30.55245,
          20000000
        ),
        orientation: {
          heading: Cesium.Math.toRadians(0),
          pitch: Cesium.Math.toRadians(-90),
          roll: 0.0
        },
        duration: 10 // fly time 10s
      });
    }
  }
};
</script>

<style lang="scss" scoped>
#cesiumContainer {
  width: 100vw;
  height: 100vh;
  margin: 0;
  padding: 0;
  overflow: hidden;
}
</style>
