最新Vue + Cesium环境配置

好记性不如烂笔头，对于一个刚接触 Vue、Cesium 的菜鸟来说，Vue + Cesium 集成之路可以说是历经艰辛，因此特意记录一下 Vue + Cesium 的配置过程，以便日后查看。

1、Vue Cli 5.0+

基于Vue3配置Cesium，软件版本如下：

@vue/cli 5.0.8
cesium 1.104
vue 3.2.13

不想看下面内容的可以直接跳转到GitHub项目。
项目地址：https://github.com/zhengjie9510/webgis-demo
配置文件简单，直接复制官方例子的配置到vue.config.js文件中，具体内容如下：

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,
  configureWebpack: {
    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' }
        ]
      }),
      new webpack.DefinePlugin({
        // Define relative base path in cesium for loading assets
        CESIUM_BASE_URL: JSON.stringify('')
      })
    ],
  }
})

2、Vue Cli 3.0+

2.1、安装

# 全局安装vue-cli 3.x版本
npm install -g @vue/cli

# 创建 vue-cesium 项目
vue create vue-cesium

# 创建好一个 vue-cesium 项目后，在项目内安装 Cesium
npm install cesium

2.2、配置

在项目文件夹下新建文件：vue.config.js，文件内容为：

const CopyWebpackPlugin = require('copy-webpack-plugin')
const webpack = require('webpack')
const path = require('path')

let cesiumSource = './node_modules/cesium/Source'
let cesiumWorkers = '../Build/Cesium/Workers'

module.exports = {
    // 基本路径 
    publicPath: "./",
    // 输出文件目录
    outputDir: "dist",
    // eslint-loader 是否在保存的时候检查
    lintOnSave: false,
    // webpack-dev-server 相关配置
    devServer: {
        open: process.platform === "darwin",
        host: "0.0.0.0",
        port: 5000,
        https: false,
        hotOnly: false
    },
    configureWebpack: {
        output: {
            sourcePrefix: ' '
        },
        amd: {
            toUrlUndefined: true
        },
        resolve: {
            alias: {
                'vue$': 'vue/dist/vue.esm.js',
                '@': path.resolve('src'),
                'cesium': path.resolve(__dirname, cesiumSource)
            }
        },
        plugins: [
            new CopyWebpackPlugin([{ from: path.join(cesiumSource, cesiumWorkers), to: 'Workers' }]),
            new CopyWebpackPlugin([{ from: path.join(cesiumSource, 'Assets'), to: 'Assets' }]),
            new CopyWebpackPlugin([{ from: path.join(cesiumSource, 'Widgets'), to: 'Widgets' }]),
            new CopyWebpackPlugin([{ from: path.join(cesiumSource, 'ThirdParty/Workers'), to: 'ThirdParty/Workers' }]),
            new webpack.DefinePlugin({
                CESIUM_BASE_URL: JSON.stringify('./')
            })
        ],
        module: {
            unknownContextCritical: /^.\/.*$/,
            unknownContextCritical: false
        }
    }
};

2.3、使用

开发时如下，直接在模块中使用 Cesium 对象即可

<template>
  <div class="map-box">
    <div id="cesiumContainer"></div>
  </div>
</template>

<script>
var Cesium = require("cesium/Cesium");
var widgets = require("cesium/Widgets/widgets.css");
export default {
  name: "",
  mounted() {
    var viewer = new Cesium.Viewer("cesiumContainer");
    //谷歌影像
    var googleImagery = new Cesium.UrlTemplateImageryProvider({
      url:
        "http://mt{s}.google.cn/vt/lyrs=s&hl=zh-CN&gl=CN&src=app&x={x}&y={y}&z={z}",
      subdomains: "0123",
    });
    viewer.imageryLayers.addImageryProvider(googleImagery);
  },
};
</script> 

<style scoped>
.map-box {
  width: 100%;
  height: 100%;
}
#cesiumContainer {
  width: 100%;
  height: 100%;
}
</style>

3、Vue Cli 2.X

3.1、安装

# 全局安装 vue-cli
npm install -g vue-cli

# 创建 vue-cesium 项目
vue init webpack vue-cesium

# 创建好一个 vue-cesium 项目后，在项目内安装 Cesium
npm install cesium

3.2、配置

需要修改 webpack.base.conf.js、webpack.dev.conf.js、webpack.prod.conf.js、config/index.js 文件

3.2.1、配置 webpack.base.conf.js

修改 1、2、3、4 处的配置

'use strict'
const path = require('path')
const utils = require('./utils')
const config = require('../config')
const vueLoaderConfig = require('./vue-loader.conf')
//配置cesium全局基础配置
//1、The path to the CesiumJS source code cesium的源码目录  
const cesiumSource = '../node_modules/cesium/Source'
//1、结束

function resolve (dir) {
  return path.join(__dirname, '..', dir)
}

module.exports = {
  context: path.resolve(__dirname, '../'),
  entry: {
    app: './src/main.js'
  },
  output: {
    path: config.build.assetsRoot,
    filename: '[name].js',
    publicPath: process.env.NODE_ENV === 'production'
      ? config.build.assetsPublicPath

      //2、Needed to compile multiline strings in Cesium
      sourcePrefix: ''
      //2、结束
  },
  resolve: {
    extensions: ['.js', '.vue', '.json'],
    alias: {
      'vue$': 'vue/dist/vue.esm.js',
      '@': resolve('src'),
      //3、CesiumJS module name 我们就可以在应用程序中引用cesium了 
      cesium: path.resolve(__dirname, cesiumSource)
      //3、结束
    }
  },
  module: {
    rules: [
      {
        test: /\.vue$/,

      },
      {
        test: /\.js$/,
        loader: 'babel-loader',
        include: [resolve('src'), resolve('test'), resolve('node_modules/webpack-dev-server/client')]
      },
      {
        test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
        loader: 'url-loader',
        options: {
          limit: 10000,
          name: utils.assetsPath('img/[name].[hash:7].[ext]')
        }
      },
      {
        test: /\.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.*)?$/,
        loader: 'url-loader',
        options: {
          limit: 10000,
          name: utils.assetsPath('media/[name].[hash:7].[ext]')
        }
      },
      {
        test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/,
        loader: 'url-loader',
        options: {
          limit: 10000,
          name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
        }
      }
    ],
    //4、屏蔽webpack 打印载入特定库时候的警告
    unknownContextCritical: false
    //4、结束
  },
  node: {
    // prevent webpack from injecting useless setImmediate polyfill because Vue
    // source contains it (although only uses it if it's native).
    setImmediate: false,
    // prevent webpack from injecting mocks to Node native modules
    // that does not make sense for the client
    dgram: 'empty',
    fs: 'empty',
    net: 'empty',
    tls: 'empty',
    child_process: 'empty'
  }
}

3.2.2、配置 webpack.dev.conf.js

const cesiumWorkers = '../Build/Cesium/Workers'
//1、结束
const HOST = process.env.HOST
const PORT = process.env.PORT && Number(process.env.PORT)

const devWebpackConfig = merge(baseWebpackConfig, {
  module: {
    rules: utils.styleLoaders({ sourceMap: config.dev.cssSourceMap, usePostCSS: true })
  },
  // cheap-module-eval-source-map is faster for development
  devtool: config.dev.devtool,

  // these devServer options should be customized in /config/index.js
  devServer: {
    clientLogLevel: 'warning',
    historyApiFallback: {
      rewrites: [
        { from: /.*/, to: path.posix.join(config.dev.assetsPublicPath, 'index.html') },
      ],
    },
    hot: true,
    contentBase: false, // since we use CopyWebpackPlugin.
    compress: true,
    host: HOST || config.dev.host,
    port: PORT || config.dev.port,

      process.env.PORT = port
      // add port to devServer config
      devWebpackConfig.devServer.port = port

      // Add FriendlyErrorsPlugin
      devWebpackConfig.plugins.push(new FriendlyErrorsPlugin({
        compilationSuccessInfo: {
          messages: [`Your application is running here: http://${devWebpackConfig.devServer.host}:${port}`],
        },
        onErrors: config.dev.notifyOnErrors
        ? utils.createNotifierCallback()
        : undefined
      }))

      resolve(devWebpackConfig)
