NodeJS的桌面应用开发 Electron

##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
