Cesium Vue（一）— 项目初始化配置

1. 创建VUE项目工程

• 创建项目

    vue create cesium-vue
  

• 配置Vue3
  

2. 创建vue.config.js文件

const { defineConfig } = require('@vue/cli-service')

// The path to the CesiumJS source code
const cesiumSource = 'node_modules/cesium/Source';
const cesiumWorkers = '../Build/Cesium/Workers';
const CopyWebpackPlugin = require('copy-webpack-plugin');
const path = require('path');
const webpack = require('webpack');

module.exports = defineConfig({
 transpileDependencies: true,
 productionSourceMap: false,
 publicPath: process.env.NODE_ENV === 'production' ? '/webgis-demo/' : '/',
 configureWebpack: {
   devtool: 'source-map',
   output: {
     sourcePrefix: ''
   },
   resolve: {
     fallback: { "https": false, "zlib": false, "http": false, "url": false },
     mainFiles: ['index', 'Cesium']
   },
   plugins: [
     // Copy Cesium Assets, Widgets, and Workers to a static directory
     new CopyWebpackPlugin({
       patterns: [
         { from: path.join(cesiumSource, cesiumWorkers), to: 'Workers' },
         { from: path.join(cesiumSource, 'Assets'), to: 'Assets' },
         { from: path.join(cesiumSource, 'Widgets'), to: 'Widgets' },
         { from: path.join(cesiumSource, 'ThirdParty'), to: 'ThirdParty' }
       ]
     }),
     new webpack.DefinePlugin({
       // Define relative base path in cesium for loading assets
       CESIUM_BASE_URL: JSON.stringify('')
     })
   ],
 }
})

3. 安装相关依赖库

"dependencies": {
    "assert": "^2.1.0",
    "browserify-zlib": "^0.2.0",
    "cesium": "^1.110.0",
    "https-browserify": "^1.0.0",
    "stream-browserify": "^3.0.0",
    "stream-http": "^3.2.0",
    "url": "^0.11.3",
    "vue": "^3.2.13"
  },

4. 运行第一个Cesium

把目标文件夹“./node_modules/cesium/Build/Cesium/Widgets” 拷贝到 “./src”文件夹目录下。

修改App.vue文件

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

<script setup>
import { onMounted } from "vue";
import * as Cesium from "cesium";
import "./Widgets/widgets.css";

onMounted(async() => {
  var viewer = new Cesium.Viewer("cesiumContainer");
});
</script>

<style>
* {
  margin: 0;
  padding: 0;
}
#cesiumContainer {
  width: 100vw;
  height: 100vh;
}
</style>

效果展示如下：
