Electron是由GitHub开发，使用 JavaScript，HTML 和 CSS 构建跨平台的桌面应用程序，可以帮我们把web网页项目直接打包成桌面应用程序。

一、所需环境&打包前准备

1、安装node.js

electron 依赖于node.js 需要安装node.js：

安装node(步骤，不是重点，略过）

2、安装electron

dos下，全局安装：

npm install -g electron

检查是否安装成功：

electron -v

3、web项目

二、打包过程

1、打包配置

在需要打包的web网页项目根目录下分别新建:main.js、package.json

package.json：在package.json中加入如下内容

{
  "name"    : "App", // 项目名称
  "version" : "0.1.0",
  "main"    : "main.js"  // 根目录下的main.js
}

main.js：在main.js中加入如下代码

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})
 
  // 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.

注意：在main.js 中的index.html 为你web项目的首页，及入口文件

2、 安装打包器

打开 DOS窗口，cd 到你的项目目录下，输入下面命令，全局安装electron打包器

npm install electron-packager -g

3、执行打包命令：

在根目录下执行打包命令：

electron-packager . app --win --out App --arch=x64 --electron-version 1.4.14 --overwrite --ignore=node_modules

打包成功后在根目录下会生成打包好的工程：

打开工程中的应用程序即可运行web项目：
