electron在window打包流程

2、参考网址

• electron 安装使用
• electron官网教程

3、学习目的

• vue项目创建
• electron软件打包

---

4、核心操作

1）vue 项目创建

vue init webpack demo

---

2）electron打包

• 添加electron和electron-builder

npm install electron --save-dev
npm install electron-packager --save-dev

• 修改打包的绝对路径config/index.js

assetsPublicPath: './',

• 添加electron的打包配置文件（在build文件夹下创建一个electron.js,拷贝以下内容）

• electron.js如下

const electron = require('electron')
// Module to control application life.
const app = electron.app
// Module to create native browser window.
const BrowserWindow = electron.BrowserWindow

// 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 mainWindow

function createWindow () {
  // Create the browser window.
  mainWindow = new BrowserWindow({width: 800, height: 600})

  // and load the index.html of the app.
  mainWindow.loadFile('./dist/index.html')

  // Open the DevTools.
  mainWindow.webContents.openDevTools()

  // Emitted when the window is closed.
  mainWindow.on('closed', function () {
    // 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.
    mainWindow = 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', function () {
  // On OS X 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', function () {
  // On OS X 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 (mainWindow === 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.

• 修改package.json

  "main":"build/electron.js",
  "scripts": {
    "dev": "webpack-dev-server --inline --progress --config build/webpack.dev.conf.js",
    "start": "npm run dev",
    "build": "node build/build.js",
    "electron_build": "electron-packager ./dist ming --platform=win32 --arch=x64 --overwrite --out ../pack"
  },

• 进行软件install和build

npm install
npm run build

• 编译之后会创建一个dist文件夹，然后将上面使用到的electron.js和package.json文件拷贝到dist文件中，修改一下对应的资源位置
• electron.js修改

mainWindow.loadFile('index.html')

• package.json修改

"main":"electron.js",

• 开始进行打包

npm run electron_build

• 找到打包后的文件运行即可
