electron 集成vue

重点先说三遍
一定安装cnpm
一定用windows自带的cmd窗口装包
一定多尝试几次

1.先用cli3初始化一个vue项目

vue create electron-vue-demo

2.修改package.json，添加以下7行：

...
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint",
+   "electron:build": "vue-cli-service electron:build",
+   "electron:serve": "vue-cli-service electron:serve",
+   "postinstall": "electron-builder install-app-deps",
+   "postuninstall": "electron-builder install-app-deps"
  },
+ "main": "background.js",
  "dependencies": {
    "core-js": "^2.6.5",
    "vue": "^2.6.6",
    "vue-router": "^3.0.1",
    "vuex": "^3.0.1"
  },
  "devDependencies": {
    "@vue/cli-plugin-babel": "^3.8.0",
    "@vue/cli-plugin-eslint": "^3.8.0",
    "@vue/cli-service": "^3.8.0",
    "@vue/eslint-config-standard": "^4.0.0",
    "babel-eslint": "^10.0.1",
+   "electron": "^5.0.6",
    "eslint": "^5.16.0",
    "eslint-plugin-vue": "^5.0.0",
    "stylus": "^0.54.5",
    "stylus-loader": "^3.0.2",
+   "vue-cli-plugin-electron-builder": "^1.3.5",
    "vue-template-compiler": "^2.6.10"
  },
  ...

3.在src目录下新建background.js，复制以下代码：

'use strict'

import { app, protocol, BrowserWindow } from 'electron'
import {
  createProtocol,
  installVueDevtools
} from 'vue-cli-plugin-electron-builder/lib'

const isDevelopment = process.env.NODE_ENV !== 'production'

// 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

// Scheme must be registered before the app is ready
protocol.registerSchemesAsPrivileged([{
  scheme: 'app',
  privileges: {
    secure: true,
    standard: true
  }
}])

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

  if (process.env.WEBPACK_DEV_SERVER_URL) {
    // Load the url of the dev server if in development mode
    win.loadURL(process.env.WEBPACK_DEV_SERVER_URL)
    if (!process.env.IS_TEST) win.webContents.openDevTools()
  } else {
    createProtocol('app')
    // Load the index.html when not in development
    win.loadURL('app://./index.html')
  }

  win.on('closed', () => {
    win = null
  })
}

// 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()
  }
})

// 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', async () => {
  if (isDevelopment && !process.env.IS_TEST) {
    // Install Vue Devtools
    try {
      await installVueDevtools()
    } catch (e) {
      console.error('Vue Devtools failed to install:', e.toString())
    }
  }
  createWindow()
})

// Exit cleanly on request from parent process in development mode.
if (isDevelopment) {
  if (process.platform === 'win32') {
    process.on('message', data => {
      if (data === 'graceful-exit') {
        app.quit()
      }
    })
  } else {
    process.on('SIGTERM', () => {
      app.quit()
    })
  }
}

4.运行
cnpm install
如果安装过程中报错：Error: post install error, please remove node_modules before retry!可以忽略，不影响后续使用
5.结果
npm run electron:serve
首次启动可能会等待很久，出现以下信息：

INFO Launching Electron...
Failed to fetch extension, trying 4 more times
Failed to fetch extension, trying 3 more times
Failed to fetch extension, trying 2 more times
...
6.打包
npm run electron:build
JS代码里，指定的对相对或绝对目录的.exe文件的调用，在用Electron-Buider打包后，不会受到破坏。但是，该.exe文件及其目录不会被打包，所以需要打包后，手动将该.exe文件及目录拷贝到打包后的unpacked类型绿色目录，便于后期再进一步打包成单个安装文件
打包前,我exe是放这里的

那么打包后(在打包成品的解压版中)

ps:其实解压版的文件目录和安装版安装好之后的文件目录是一样的哦
