安装cesium
在已有项目中执行,
npm i cesium
修改配置
build/webpack.base.conf.js
1、定义 Cesium 源码路径
const cesiumSource = '../node_modules/cesium/Source'
'use strict'
const path = require('path')
const utils = require('./utils')
const config = require('../config')
const vueLoaderConfig = require('./vue-loader.conf')
//--cesium--配置
const cesiumSource = '../node_modules/cesium/Source';2、在output 里加入sourcePrefix: ' ' 让webpack 正确处理多行字符串
3、配置 amd参数
4、module中在rules后添加 unknownContextCritical: false,
module.exports = {
context: path.resolve(__dirname, '../'),
entry: {
app: ["babel-polyfill", './src/main.js']
},
output: {
path: config.build.assetsRoot,
filename: '[name].js',
publicPath: process.env.NODE_ENV === 'production' ?
config.build.assetsPublicPath : config.dev.assetsPublicPath,
//--cesium--配置------------------------------------
sourcePrefix: ' '
},
//--cesium--配置----------------------------------------
amd:{
toUrlUndefined: true
},
resolve: {
extensions: ['.js', '.vue', '.json'],
alias: {
'vue$': 'vue/dist/vue.esm.js',
'@': resolve('src'),
//--cesium--配置
'cesium': path.resolve(__dirname, cesiumSource)
}
},
module: {
rules: [
...
],
//--cesium--配置-------------------------------------
//unknownContextRegExp: /^.\/.*$/
unknownContextCritical: false,
}
}build/webpack.dev.conf.js
1、定义 Cesium 源码路径和Cesium Workers 路径
const cesiumSource = 'node_modules/cesium/Source' const cesiumWorkers = '../Build/Cesium/Workers'
（注意这里的 node_modules 与webpack.base.conf.js的不同，前面没有../）
2、定义CESIUM_BASE_URL变量
3、在plugins 中加入下面插件,拷贝静态资源
plugins: [
new webpack.DefinePlugin({
'process.env': require('../config/dev.env'),
//--cesium--配置-------------------------------------------
'CESIUM_BASE_URL': JSON.stringify('')
}),
new webpack.HotModuleReplacementPlugin(),
new webpack.NamedModulesPlugin(), // HMR shows correct file names in console on update.
new webpack.NoEmitOnErrorsPlugin(),
// https://github.com/ampedandwired/html-webpack-plugin
new HtmlWebpackPlugin({
filename: 'index.html',
template: 'index.html',
inject: true
}),
//--cesium--配置---------------------------------------------
new CopyWebpackPlugin([ { from: path.join(cesiumSource, cesiumWorkers), to: 'Workers' } ]), //flag
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 CopyWebpackPlugin([ { from: 'ThirdParty', to: 'ThirdParty' } ]),
// copy custom static assets
new CopyWebpackPlugin([
{
from: path.resolve(__dirname, '../static'),
to: config.dev.assetsSubDirectory,
ignore: ['.*']
}
])
]build/webpack.prod.conf.js
1、定义
const cesiumSource = 'node_modules/cesium/Source'; const cesiumWorkers = '../Build/Cesium/Workers';
2、定义'CESIUM_BASE_URL'变量
3、在plugins 中加入下面插件,拷贝静态资源
plugins: [
// http://vuejs.github.io/vue-loader/en/workflow/production.html
new webpack.DefinePlugin({
'process.env': env,
//--cesium--配置--------------------------------------
'CESIUM_BASE_URL': JSON.stringify('static')
}),
...
new HtmlWebpackPlugin({
...
},
//--cesium--配置--------------------------------------
new CopyWebpackPlugin([ { from: path.join(cesiumSource, cesiumWorkers), to: 'static/Workers' } ]),//flag
new CopyWebpackPlugin([ { from: path.join(cesiumSource, 'Assets'), to: 'static/Assets' } ]),
new CopyWebpackPlugin([ { from: path.join(cesiumSource, 'Widgets'), to: 'static/Widgets' } ]),
new CopyWebpackPlugin([ { from: path.join(cesiumSource, 'ThirdParty/Workers'), to: 'ThirdParty/Workers' } ]),
new CopyWebpackPlugin([ { from: 'ThirdParty', to: 'ThirdParty' } ]),
