现在基于 js 和 web浏览器核心构建的 c/s 程序越来越多，比如微信桌面版（基于 duilib 和 cef）、vs code（基于electron）等，出于了解的目的，最近学习了 electron。electron具体是什么，可以做什么，这里不做过多的介绍，网上很多相关的介绍，这里主要介绍在vs2017下怎么进行 electron 应用程序的开发。
一、环境搭建
安装 node.js 及 npm。
安装 vs2017 ，必须安装 node.js web开发包。
二、创建空白 Node.js 控制台应用程序项目
创建好的项目结构入下：
三、编写 electron Hello Word
参照 ：
1、打开 package.json 加入：
"dependencies": {"electron": "^1.6.6"}最后内容如下：
{"name": "electron-hello-word","version": "0.0.0","description": "ElectronHelloWord","main": "app.js?1.1.11","author": {"name": "Starts_2000"},"dependencies": {"electron": "^1.6.6"}
}2、打开 app.js，输入以下内容：

'use strict';
const { app, BrowserWindow } = require('electron')
const path = require('path')
const url = require('url')// Keep a global reference of the window object, if you don't, the window will// be closed automatically when the JavaScript object is garbage collected.let winfunction createWindow() {// Create the browser window.win = new BrowserWindow({ width: 800, height: 600 })// and load the index.html of the app. win.loadURL(url.format({
pathname: path.join(__dirname, 'index.html'),
protocol: 'file:',
slashes: true}))// Open the DevTools. win.webContents.openDevTools()// Emitted when the window is closed.win.on('closed', () => {// Dereference the window object, usually you would store windows// in an array if your app supports multi windows, this is the time// when you should delete the corresponding element.win = null})
}// This method will be called when Electron has finished// initialization and is ready to create browser windows.// Some APIs can only be used after this event occurs.app.on('ready', createWindow)// Quit when all windows are closed.app.on('window-all-closed', () => {// On macOS it is common for applications and their menu bar// to stay active until the user quits explicitly with Cmd + Qif (process.platform !== 'darwin') {
app.quit()
}
})
app.on('activate', () => {// On macOS it's common to re-create a window in the app when the// dock icon is clicked and there are no other windows open.if (win === null) {
createWindow()
}
})// In this file you can include the rest of your app's specific main process// code. You can also put them in separate files and require them here.3、新建 index.html 文件
<!DOCTYPE html><html><head><meta charset="UTF-8"><title>Hello World!</title></head><body><h1>Hello World!</h1>We are using node<script>document.write(process.versions.node)</script>,
Chrome<script>document.write(process.versions.chrome)</script>,
and Electron<script>document.write(process.versions.electron)</script>.</body></html>四、设置和运行
1、NPM 安装 electron 包
安装成功后可看到，点击解决方案上方的显示所有文件，可以看到
2、设置项目 Node.exe路径为：
.\node_modules\electron\dist\electron.exe
运行解决方案，就可以看到electron 的 Hello Word示例了：
