Vue+Cesium项目环境搭建 https://blog.csdn.net/HeHeDayou/article/details/94727051
基于Webpack的Cesium+Vue应用 https://blog.csdn.net/m0_37972557/article/details/79768408?depth_1-utm_source=distribute.pc_relevant.none-task&utm_source=distribute.pc_relevant.none-task
cesium1.66+vue填坑记录 https://blog.csdn.net/weizhixiang/article/details/1044738561、运行环境介绍
| 环境 | 操作系统 | Google Chrom |
Node.js |
Npm |
Webpack |
Vue |
Cesium |
| 版本 | Win10 x64 | 80.0.3987.122 | v12.16.1 |
v6.14.1(node 已经集成 无需单独安装) |
v4.41.6 |
v2.9.6 |
v1.66.0 |
2、基础环境安装
预先设置 使用taobao的npm镜像 (国外的下载速度 极慢)
npm config set registry https://registry.npm.taobao.org2.1 Node.js 请自行安装
2.2 webpack
npm install webpack -g 2.3 Vue-cli 脚手架
npm install vue-cli -g3、使用vue-cli 的webpack 模板 生成模板应用
vue-cli 官方提供的几个模板
vue-list //使用该命令查看vue 提供的应用模板
我们要开始生成模板应用啦！！！
vue init webpack vue_cesium //webpack 为模板名 vue_cesium 即我们要新建的项目名称之后就是一些需要填写 关于项目的信息 本例填写如下
生成完成之后 切入项目目录下 执行命令 npm run dev 看到如下画面时，按照指示用浏览器访问 http://localhost:8080
模板应用创建成功啦！！！
4、安装cesium模块
npm install cesium --save //使用该命令行 安装cesium 模块
npm install [email protected] --save //安装指定版本的Cesium模块 5、配置webpack
以下以 vue_cesium 指代项目根目录
5.1 配置 webpack.base.conf.js
位于vue_cesium/build/ 目录下 请将该配置文件中标注的1、2、3、4 处配置全部正确配置
'use strict'
const path = require('path')
const utils = require('./utils')
const config = require('../config')
const vueLoaderConfig = require('./vue-loader.conf')
//1、The path to the CesiumJS source code cesium的源码目录
const cesiumSource = '../node_modules/cesium/Source'
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 : config.dev.assetsPublicPath,
//2、 Needed to compile multiline strings in Cesium
sourcePrefix: ''
},
resolve: {
extensions: ['.js', '.vue', '.json'],
alias: {
'vue$': 'vue/dist/vue.esm.js',
'@': resolve('src'),
//3、 CesiumJS module name 我们就可以在应用程序中引用cesium了
cesium: path.resolve(__dirname, cesiumSource)
}
},
module: {
rules: [{
test: /\.vue$/,
loader: 'vue-loader',
options: vueLoaderConfig
},
{
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: {

loader: 'url-loader',
options: {
limit: 10000,
name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
}
}
],
//4、
unknownContextCritical: false
},
node: {
// prevent webpack from injecting useless setImmediate polyfill because Vue
// source contains it (although only uses it if it's native).

}6、引用Cesium 开发示例应用
6.1 在main.js中引入cesium
位于 vue_cesium/src/ 目录下
// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'
//新版本的cesium 不支持以前的import 方式导入 这是个坑
var Cesium = require('cesium/Cesium');
var widgets = require('cesium/Widgets/widgets.css');
//此处将cesium 赋给全局
Vue.prototype.Cesium = Cesium
Vue.prototype.widgets = widgets
Vue.config.productionTip = false
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
components: { App },
template: '6.2 在components目录下 新建vue组件 CesiumViewer.vue
位于 vue_cesium/src/components 目录下
6.3 配置路由
位于 vue_cesium/src/router 目录下
import Vue from 'vue'
import Router from 'vue-router'
import CesiumViewer from '@/components/CesiumViewer'
Vue.use(Router)
export default new Router({
routes: [{
path: '/',
name: 'CesiumViewer',
component: CesiumViewer
}]
})6.4 App.vue
位于 vue_cesium/src/ 目录下
7. 翻滚吧！Cesium ...
在项目根目录下 使用命令行 执行 npm run dev 成功后 再次访问http://localhost:8080
当你看到如下 画面时说明 你已经集成成功了...
