nodejs可以开发桌面应用吗？
nodejs可以开发桌面应用。目前用Nodejs开发桌面应用，主要有两种方案：NW.js和Electron框架。NW.js是Intel的工程师写的一个基于node.js和chromium的应用程序运行环境。Electron是一款利用Web技术开发跨平台桌面应用的框架。
下面给大家简单介绍一下使用Electron进行NodeJS的桌面应用开发。
##开发环境及版本号##
NodeJS ： 7.2.0
Electron ： 1.4.10
##开始教程##
安装各个应用：
安装electron的包
npm install -g electron
安装 aser 打包工具
npm install -g asar
安装 packager 发布工具
npm install -g electron-packager
建立空的 nodejs 项目：
npm init
建立js程序 index.js :
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 win
function createWindow () {
// Create the browser window.
win = new BrowserWindow({width: 800, height: 600,autoHideMenuBar :true})
win.setMenu(null);
// 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 + Q
if (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.package.json 中添加依赖，最终的格式：
{
"name": "app",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC",
"dependencies": {
"electron": "^1.4.10"
}
}当然你也可以用npm start执行在scripts中添加start的命令
添加index.html 文件：
<!DOCTYPE HTML>
<html>
<head>
<meta charset="UTF-8"/>
<title>Hello World</title>
</head>
<body>
Hello World!
</body>
</html>然后执行运行命令：
electron .
. 是指当前目录
开始打包，进入项目：
asar abc path app.asar
然后到app.asar目录下开始发布：
electron-packager abc --all
至此当前目录下会有一个可执行程序的目录进入点开exe程序就可以了
