如果我们的技术栈是react，也想要用electron来开发一个桌面的多端应用该怎么做呢？这篇文章选择了react的技术栈，讲解了环境的初始化步骤

步骤

在这里插入图片描述

创建 react 项目

npm create vite@latest my-react-app

安装依赖

cd my-react-app
npm install

启动项目

npm run dev

浏览器能打开我们的 app 页面即可。

安装 electron

npm install electron -D
npm i electron-builder -D

注意：这两个依赖包是开发环境依赖，生产环境不需要安装。否则，后面打包应用会报错

完整的配置文件如下：

    "vite": "^5.3.4",
    "vite-plugin-electron-renderer": "^0.14.5"
  }
}

如果报错，按提示安装即可。问题不大。

修改 packge.json
添加"main": "./electron/main.js",，删除type:module,添加desctiption,添加author
创建 electron 目录

mkdir electron

创建 main.js

touch electron/main.js
touch electron/preload.js

增加.npmrc 配置

strict-ssl=false
registry=https://registry.npmmirror.com/
electron_mirror=https://registry.npmmirror.com/-/binary/electron/
electron_builder_binaries_mirror=https://registry.npmmirror.com/-/binary/electron-builder-binaries/
# ELECTRON_BUILDER_BINARIES_MIRROR=https://mirrors.huaweicloud.com/electron-builder-binaries/

配置 vite.config.js

import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import electron from "vite-plugin-electron/simple";

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    react(),
    electron({
      main: {
        // `build.lib.entry的快捷方式`
        entry: "electron/main.js",
      },
      preload: {
        //`build.rollupOptions.input的快捷方式`
        input: "electron/preload.js",
      },
      // 可选：在渲染器进程中使用Node.js API
      renderer: {},
    }),
  ],
});
