基于Electron27+Vite4+React18搭建桌面端项目|electron多开窗口实践

Posted on by hackdl

前段时间有分享一篇electron25+vite4搭建跨桌面端vue3应用实践。今天带来最新捣鼓的electron27+react18创建跨端程序、electron多开窗体(模拟QQ登录窗口切换主窗口)、自定义无边框窗口拖拽导航栏的一些知识分享。

electron团队更新迭代比较快，目前稳定版本已经升级到了electron27。而且运行及构建速度有了大幅度的提升！

  • 版本信息

"vite": "^4.4.5"
"react": "^18.2.0"
"electron": "^27.0.1"
"electron-builder": "^24.6.4"
"vite-plugin-electron": "^0.14.1"

  • 搭建react18项目

使用vite4构建工具创建react项目模板。

yarn create vite electron-vite4-react18
# 选择创建react模板
cd electron-vite4-react18
yarn install
yarn dev

至此，一个基础的react模板项目就创建好了。接下来就是安装electron相关的依赖配置。

  • 安装electron关联依赖包

注意：如果安装出现卡顿情况，建议设置淘宝镜像源。

// 安装electron
yarn add -D electron
// 安装electron-builder 用于构建打包可安装exe程序
yarn add -D electron-builder
// 安装electron-devtools-installer 用于开发调试electron项目
yarn add -D electron-devtools-installer

另外还需要安装一个electron和vite的桥接插件vite-plugin-electron。

yarn add -D vite-plugin-electron

vite-plugin-electron：一款快速集成整合Vite和Electron，方便在渲染进程中使用Node API或Electron API功能。

到这里，所依赖的electron插件已经安装完毕。接下来就是创建主进程，启动项目了。

  • 创建主进程配置

const { app, BrowserWindow } = require('electron')

const MultiWindow = require('./src/windows')

const createWindow = () => {
    let win = new MultiWindow()
    win.createWin({ isMainWin: true })
}

app.whenReady().then(() => {
    createWindow()
    app.on('activate', () => {
        if (BrowserWindow.getAllWindows().length === 0) createWindow()
    })
})

app.on('window-all-closed', () => {
    if (process.platform !== 'darwin') app.quit()
})

配置vite.config.js

在vite.config.js中引入vite-plugin-electron配置主进程入口electron-main.js文件。

import { defineConfig, loadEnv } from 'vite'
import react from '@vitejs/plugin-react'
import electron from 'vite-plugin-electron'
import { resolve } from 'path'
import { parseEnv } from './src/utils/env'

// https://vitejs.dev/config/
export default defineConfig(({ command, mode }) => {
    const viteEnv = loadEnv(mode, process.cwd())
    const env = parseEnv(viteEnv)

    return {
        plugins: [
            react(),
            electron({
                entry: 'electron-main.js',
            })
        ],

        esbuild: {
            // 打包去除 console.log 和 debugger
            drop: env.VITE_DROP_CONSOLE && command === 'build' ? ["console", "debugger"] : []
        },

        /* 开发服务器配置 */
        server: {
            // 端口
            port: env.VITE_PORT,
            // 代理配置
            proxy: {
                // ...
            }
        },

        resolve: {
            // 设置别名
            alias: {
                '@': resolve(__dirname, 'src'),
                '@assets': resolve(__dirname, 'src/assets'),
                '@components': resolve(__dirname, 'src/components'),
                '@views': resolve(__dirname, 'src/views')
            }
        }
    }
})

配置package.json

在package.json文件中加入“main”: “electron-main.js”入口配置，并且需要去掉“type”: “module”。

注意：官方提示electron28之后可以支持”type”: “module”

接下来就运行yarn electron:serve桌面端项目就能运行了。

至于一些electron打包配置，这里就不详细介绍了，之前有相关分享的文章。

  • electron自定义无边框拖拽导航栏

创建窗口的时候设置 frame: false 即可创建一个无系统边框的窗体。

通过css设置 -webkit-app-region: drag 来实现拖拽区域。设置 -webkit-app-region: no-drag 取消拖拽响应。

自定义最大化/最小化/关闭

import { useState, useContext } from 'react'
import { Modal } from '@arco-design/web-react'
import { setWin } from '@/windows/action'

function WinBtn(props) {
  const {
    color = '#fff',
    minimizable = true,
    maximizable = true,
    closable = true,
    zIndex = 2023,

    children
  } = props

  const [hasMaximized, setHasMaximized] = useState(false)

  window.electronAPI.invoke('win__isMaximized').then(res => {
    setHasMaximized(res)
  })
  window.electronAPI.receive('win__hasMaximized', (e, res) => {
    setHasMaximized(res)
  })

  // 最小化
  const handleWinMin = () => {
      window.electronAPI.send("win__minimize")
  }
  // 最大化/还原
  const handleWinMax2Min = () => {
      window.electronAPI.invoke("win__max2min").then(res => {
          console.log(res)
          setHasMaximized(res)
      })
  }
  // 关闭
  const handleWinClose = () => {
      if(window.config.isMainWin) {
        Modal.confirm({
          title: '提示',
          content: div style={{ textAlign: 'center' }}>是否最小化至托盘，不退出程序？div>,
          okButtonProps: {status: 'warning'},
          sty服务器托管网le: {width: 360},
          cancelText: '最小化至托盘',
          okText: '残忍退出',
          onOk: () => {
            setWin('close')
          },
          onCancel: () => {
            setWin('hide', window.config.id)
          }
        })
      }else {
          setWin('close', window.config.id)
      }
  }

module.exports = MultiWindow

electron支持的一些环境变量。

process.env.NODE_ENV
process.env.VITE_DEV_SERVER_URL

另外需要注意，__dirname变量指向当前文件。如：src/windows/index.js文件，则根目录需要../../返回。
