前言

　　最近想把自己用html+css+js做的網頁界面打包成桌面應用，網上一搜，發現Electron是一個不錯的選擇，試了試，發現效果真的不錯。這里記錄一下打包過程以作記錄，便於自己以后查看學習。

一、簡介

　　Electron是由Github開發，用HTML，CSS和JavaScript來構建跨平台桌面應用程序的一個開源庫。 Electron通過將Chromium和Node.js合並到同一個運行時環境中，並將其打包為Mac，Windows和Linux系統下的應用來實現這一目的。

二、打包過程

1.首先保證自己計算機全局安裝了nodejs，並且利用nodejs自帶的npm全局安裝了electron和打包神器electron-packager。兩個命令：（npm install electron -g），(npm install electron-packager -g)。注意：npm速度較慢，可以嘗試用cnpm，下載安裝速度快。

2.在自己的前端網頁項目文件夾下，新建 package.json、main.js、index.html 三個文件（注：其中的 index.html 是你的網頁首頁，就是自己已經寫好的網頁界面）。

3.在 package.json 中添加如下內容：（name屬性值可以自定義，Version屬性值也可以自定義，main屬性值是根據新建的main.js文件名來的）

{
  "name"    : "app-name",
  "version" : "0.1.0",
  "main"    : "main.js"
}

4.在main.js中插入如下代碼：

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()     //注意：這行代碼取消注釋的話，就可以使打包生成的應用程序帶有開發者模式，類似於chrome的調試模式，可以調試程序的出現的bug
 
  // 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.
