Electron Vue3.0搭建

1、准备环境

需准备以下环境:

1. nodejs
2. vue-cli

2、使用vue-cli创建项目

1. 打开cmd,输入 vue ui 打开vue可视化界面
   
2. 在弹出的vue项目管理器网页中创建项目
   

3、添加vue-cli-plugin-electron-builder插件

在vue可视化界面中点击插件--->添加插件--->搜索vue-cli-plugin-electron-builder插件--->安装

4、运行

在终端执行 yarn electron:serve 启动

5、备注

1、每次启动很慢

每次 yarn electron:serve 启动APP，出现如下信息：

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

这是因为在请求安装vuejs devtools插件。需要kexue上网才能安装成功。如果不能kexue上网也没关系，耐心等待5次请求失败后会自动跳过。或者可以通过去掉加载vuejs devtools插件代码来实现：

//background.js中

'use strict'

import { app, protocol, BrowserWindow } from 'electron'
import { createProtocol } from 'vue-cli-plugin-electron-builder/lib'
// 去掉这段代码
// import installExtension, { VUEJS_DEVTOOLS } from 'electron-devtools-installer'
const isDevelopment = process.env.NODE_ENV !== 'production'

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

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

      // Use pluginOptions.nodeIntegration, leave this alone
      // See nklayman.github.io/vue-cli-plugin-electron-builder/guide/security.html#node-integration for more info
      nodeIntegration: process.env.ELECTRON_NODE_INTEGRATION,
      contextIsolation: !process.env.ELECTRON_NODE_INTEGRATION
    }
  })

  if (process.env.WEBPACK_DEV_SERVER_URL) {
    // Load the url of the dev server if in development mode
    await 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')
  }
}

// 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 (BrowserWindow.getAllWindows().length === 0) 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 () => {
  // 去掉这段代码
  // if (isDevelopment && !process.env.IS_TEST) {
  //   // Install Vue Devtools
  //   try {
  //     await installExtension(VUEJS_DEVTOOLS)
  //   } 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()
    })
  }
}

2、开启vue-devtools

在background.js中把：

import installExtension, { VUEJS_DEVTOOLS } from 'electron-devtools-installer'

改为

import installExtension, { VUEJS3_DEVTOOLS } from 'electron-devtools-installer'

下面相应的调用也要改

await installExtension(VUEJS3_DEVTOOLS)
