Electron + Vue3 + TS + Vite 搭建桌面应用

参考：https://blog.csdn.net/mo911108/article/details/131456698

npm -v
10.2.4

npm create vite@latest gcto-electron-app --template vue-ts

运行项目

npm run dev

切换镜像源并安装electron，需要设置ELECTRON_MIRROR才行，win10操作如下：

set ELECTRON_MIRROR=http://npm.taobao.org/mirrors/electron/
//安装electron
npm install electron -D
//打包工具
npm install electron-builder -D
//开发工具
npm install electron-devtools-installer -D
//集成Vite和Electron，方便后续在渲染进程中使用Node API或Electron API
npm install vite-plugin-electron -D
npm install vite-plugin-electron-renderer -D
 
//快速删除某些文件和文件夹
npm install rimraf -D    

在项目的根目录下新建electron-main文件夹，之后新建index.ts，配置如下：

 // electron-main/index.ts
import { app, BrowserWindow } from "electron"
import path from "path"
 
const createWindow = () => {
  const win = new BrowserWindow({
    webPreferences: {
      contextIsolation: false, // 是否开启隔离上下文
      nodeIntegration: true, // 渲染进程使用Node API
      preload: path.join(__dirname, "./preload.js"), // 需要引用js文件
    },
  })
 
  // 如果打包了，渲染index.html
  if (process.env.NODE_ENV !== 'development') {
    win.loadFile(path.join(__dirname, "./index.html"))
    win.webContents.openDevTools()
  } else {
    let url = "http://localhost:5173" // 本地启动的vue项目路径。注意：vite版本3以上使用的端口5173；版本2用的是3000
    win.loadURL(url)
    win.webContents.openDevTools()
  }
}
 
app.whenReady().then(() => {
  createWindow() // 创建窗口
  app.on("activate", () => {
    if (BrowserWindow.getAllWindows().length === 0) createWindow()
  })
})
 
// 关闭窗口
app.on("window-all-closed", () => {
  if (process.platform !== "darwin") {
    app.quit()
  }
}) 

项目根目录创建electron-preload目录，在electron-preload目录新建preload.ts文件，参考示例代码如下：

// electron-preload/preload.ts
import os from "os";
console.log("platform", os.platform());

修改vite.config.ts，将当前独立的vite与electron关联起来

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
 
import electron from "vite-plugin-electron"
import electronRenderer from "vite-plugin-electron-renderer" 
import polyfillExports from "vite-plugin-electron-renderer" 
 
export default defineConfig(({ mode }) => ({
  base: mode == 'development' ? '' : './',
  plugins: [
    vue(),
    electron([{
      entry: "electron-main/index.ts", // 主进程文件
    },
    {
      entry: 'electron-preload/preload.ts'
    }
  ]),
    electronRenderer(),
    polyfillExports(),
  ],
  build: {
    emptyOutDir: false, // 默认情况下，若 outDir 在 root 目录下，则 Vite 会在构建时清空该目录
    outDir: "dist-electron"
  },
}))

修改tsconfig.json
增加electron相关的监听，增加配置内容如下

"include": ["src/**/*.ts", "src/**/*.d.ts", "src/**/*.tsx", "src/**/*.vue","electron-main/**/*.ts","electron-preload/**/*.ts"],

修改package.json

1. 删除"type":“module”
2. 增加"main": “dist-electron/index.js”
3. “build"修改为"build”: “rimraf dist-electron && vite build && electron-builder”
4. 修改dev运行命令，增加chcp 65001支持中文显示，“scripts”: {“dev”: “chcp 65001 && vite”}
5. （如果不涉及打包，可以不配置）增加配置build配置（配置build才能打包成功，具体含义可以官网查询），注意files及output配置的路径，files打包关联路径，output为后续包生成路径

{
  "name": "gcto-electron-app",
  "private": true,
  "version": "0.0.0",
  "main": "dist-electron/index.js", 
  "scripts": {
    "dev": "vite",
    "build": "rimraf dist-electron && vite build && electron-builder",
    "preview": "vite preview",
    "start": "electron ."
  },

运行

npm run dev
