Electron入手记录(原有Vue项目中添加Electron)

前言

这是开发三端的一个框架，Win + Linux + MAC

• 官方文档
• W3C教程
• 中文文档

入手

秉持一贯风格，上代码
首先package.json添加一些东西，参照google的方法添加注释

"main": "main.js",
  "build": {
    "//": "",
    "appId": "Flands",
    "copyright": "Open Totally",
    "compression": "normal",
    "//": "不知道干嘛的，nsis是微软的一个打包程序，自行搜索",
    "nsis": {
      "oneClick": true,
      "perMachine": true,
      "runAfterFinish": true
    },
    "//": "关键点，这是要打包进去的文件，就资源+html+main.js",
    "//": "因为我用的vue，编译后是这些东西，添加就好",
    "files": [
      "dist/static",
      "dist/*.html",
      "*.js"
    ]
  },
  "scripts": {
    "dev": "node build/dev-server.js",
    "build": "node build/build.js",
    "//": "分别是调试运行，打包exe运行，打包成单个exe文件",
    "//": "打包在dist/win-unpacked里，有个exe文件就是",
    "start": "electron .",
    "pack": "electron-builder --dir",
    "dist": "electron-builder"
  },
  "devDependencies": {
    "//": "添加的框架，注意是dev里，builder是打包的工具，packager是builder的依赖",
    "electron": "^1.7.9",
    "electron-builder": "^19.48.2",
    "electron-packager": "^10.1.0",
  }

根目录创建main.js,这是配置文件

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

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 mainWindow

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

  // and load the index.html of the app.
  mainWindow.loadURL(url.format({
    pathname: path.join(__dirname, './dist', 'index.html'),
    protocol: 'file:',
    slashes: true
  }))

  // 自动打开调试台
  mainWindow.webContents.openDevTools({
    detach: true
  });

  // 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.

运行

参考package里添加的脚本，三选一
npm run [start] [pack] [dist]

热模块替换

• webpack自带的热模块更新功能
• 在main.js里写入 mainWindow.loadURL('http://localhost:8090/' + '#')即可
• 地址填自己的端口号

使用Electron框架的功能

在需要的vue页面中添加

  if (window.require) {
    var ipc = window.require('electron').ipcRenderer
  }

方法里添加

if (window.require) {
    ipc.send('close');
  }

原因:直接require会导致提示找不到fs模块，需要使用window.require,但是在Chrome环境中提示window.require not function所以需要做一次判断
在Electron的main.js里添加

const ipc = require('electron').ipcMain
ipc.on('close', e => mainWindow.close());

注意事项

• 使用vue-router的话必须用Hash模式，不能使用history
