前言
Electron是由Github开发,用HTML,CSS和JavaScript来构建跨平台桌面应用程序的一个开源库。 Electron通过将Chromium和Node.js合并到同一个运行时环境中,并将其打包为Mac,Windows和Linux系统下的应用来实现这一目的。
Electron于2013年作为构建Github上可编程的文本编辑器Atom的框架而被开发出来。这两个项目在2014春季开源。
目前它已成为开源开发者、初创企业和老牌公司常用的开发工具。 看看谁在使用Electron 。
继续往下阅读可以了解Electron的贡献者们和已经发布的版本,或者直接阅读快速开始指引来开始用Electron来构建应用。

一、初始化项目
运行,vue init simulatedgreg/electron-vue 项目名称
vue init simulatedgreg/electron-vue admin
这里的项目名称是“admin”
如果没有安装vue脚手架,请查看《spring boot + vue + element-ui全栈开发入门——windows开发环境》
一路回车
然后运行npm install来安装依赖,运行方式和之前一样。
如果遇到run dev或者run build的时候出错,可能是因为国内的网络下载“electron-v1.8.3-win32-x64.zip”出错,这时,你需要设置npm的代理:
npm config set proxy http://服务器IP或域名:端口号 npm config set https-proxy http://服务器IP或域名:端口号
如果需要用户名密码:
npm config set proxy http://用户名:密码@服务器IP或域名:端口号
npm config set https-proxy http://用户名:密码@服务器IP或域名:端口号
设置回原库
npm config set registry http://registry.npmjs.org
也可以使用yarn。
npm install -g yarn
安装依赖、开发模式运行和编程的命令分别是:
yarn install yarn run dev yarn run build
项目构建完毕后,结构如下图所示:
和之前项目区别是,main是用于桌面程序的代码,render是用于渲染的代码。我们只需要在render文件夹里写代码就可以。
开发模式运行:
npm run dev
二、代码编写
参照《spring boot + vue + element-ui全栈开发入门——集成element-ui》安装所需的依赖
cnpm install --save element-ui cnpm install --save-dev node-sass cnpm install --save-dev sass-loader
cnpm install --save font-awesome
参照《spring boot + vue + element-ui全栈开发入门——前端列表页面开发》的代码如下:
入口文件:
import Vue from 'vue' import axios from 'axios' import App from './App' import router from './router' import store from './store' if (!process.env.IS_WEB) Vue.use(require('vue-electron')) Vue.http = Vue.prototype.$http = axios axios.defaults.baseURL = 'http://localhost:18080' Vue.config.productionTip = false import 'font-awesome/css/font-awesome.min.css' import ElementUI from 'element-ui' //原始风格 // import 'element-ui/lib/theme-chalk/index.css' //自定义风格 import './assets/theme/element-#09345f/index.css' Vue.use(ElementUI) /* eslint-disable no-new */ new Vue({ components: { App }, router, store, template: '' }).$mount('#app')
其中 axios.defaults.baseURL = 'http://localhost:18080' 是设置后端项目URL,而这可以根据具体情况写到配置文件中,开发环境调用开发环境的配置,生产环境调用生产环境配置。
路由文件:
import Vue from 'vue' import Router from 'vue-router' Vue.use(Router) import Main from '@/pages/Main' import Dashboard from '@/pages/Dashboard' import Member from '@/pages/Member' // let routes = [ // { // path: '/', // name: 'landing-page', // component: require('@/components/LandingPage').default // }, // { // path: '*', // redirect: '/' // } // ] let routes = [{ path: '/', component: Main, hidden: true, children: [{ path: '/', component: Dashboard, name: '首页' }] }] routes.push({ path: '/member', name: '会员管理', component: Main, iconCls: 'fa fa-user-circle-o', children: [{ path: '/member/data', component: Member, name: '会员信息管理' }] }) const router = new Router({ routes: routes }) export default router

结构如下图所示:
还有,在运行之前,我们需求修改src/main/index.js的配置:
function createWindow() { /** * Initial window options */ mainWindow = new BrowserWindow({ height: 563, useContentSize: true, width: 1000, webPreferences: { webSecurity: false } })
其目的是为了实现js跨域。
运行之前项目的后端项目《spring boot + vue + element-ui全栈开发入门——spring boot后端开发》:
mvn package java -jar target/demo.jar
运行项目,效果如下:
二、生成安装包
npm run build
如提示缺少vue组建,是因为registry的问题,因为国内taobao镜像没有Electron的依赖环境。所以需要设置回默认的 registry,并使用设置proxy的方式下载依赖环境。
如果提示“icon source "build/icons/icon.ico" not found”
就把“icons”加到build目录下,下载icons请点击链接,根据具体情况修改icons。
生成好后,出现“admin Setup 0.0.0.exe”的文件,即安装程序。
我运用这个安装程序后,打开刚刚开发好的程序,效果如图所示:
发现,虽然只用到了一些前端技术,但已经能够开发出桌面应用了。小时候,老师说:“学好数理化,走遍天下都不怕”。而现在是:“学会了node,任何平台的前端都不怕”。
