vue2.0项目集成Cesium的实现方法       这篇文章主要介绍了vue2.0项目集成Cesium的实现方法,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧
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(),
 // ampedandwired/html-webpack-plugin
 new HtmlWebpackPlugin({
 ',
 ',
 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: [
 // vue-loader/en/
 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' } ]),
 ...

ThirdParty

在项目根目录新建文件夹ThirdParty,放入draco_decoder.wasm文件,在加载gltf模型文件需要用到

以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持凡科。
