这里我将讲解一下从0搭建一个electron最简版架子，以及如何实现打包自动化更新
之前我有写过两篇文章关于electron框架概述以及 常用api的使用，感兴趣的同学可以看看
Electron桌面应用开发
Electron桌面应用开发2
搭建electron
官方文档：https://www.electronjs.org/zh/
只需要三个文件就可以跑起来electron
创建一个文件目录
mkdir my-electron-app && cd my-electron-app
yarn init
然后，将 electron 包安装到应用的开发依赖中。
yarn add --dev electron
{"name": "my-electron-app","version": "1.0.0","description": "Hello World!","main": "main.js", // 入口文件"author": "Jane Doe","license": "MIT","scripts": {"start": "electron ."},"devDependencies": {"electron": "^27.0.3",}
}
main.js
const createWindow = () => {const win = new BrowserWindow({width: 800,height: 600})win.loadFile('index.html') // 加载index.html
}
index.html
<!DOCTYPE html>
<html><head><meta charset="UTF-8"><!-- https://developer.mozilla.org/zh-CN/docs/Web/HTTP/CSP --><meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self'"><title>你好!</title></head><body><h1>你好!</h1>我们正在使用 Node.js <span id="node-version"></span>,Chromium <span id="chrome-version"></span>,和 Electron <span id="electron-version"></span>.</body>
</html>
yarn start就可以启动起来，这是最简版的框架
配置打包、自动升级
这里强调一下
做mac的打包需要开通苹果开发者账号，购买证书，打包需要签名，这里购买和配置的流程很复杂就不做过多赘述，都搜的到。
其实windows也需要签名 证书，但是不提供也可以打包
打包和自动升级用到了官方提供的两个工具
打包：electron-builder
升级：electron-updater
electron-builder官方文档地址：https://www.electron.build/configuration/win#WindowsConfiguration-certificateSubjectName
如果觉得英文看着不方便，有大神中文总结了一下，地址：https://blog.csdn.net/qq_38830593/article/details/89843722
首先下载这两个库：
yarn add electron-builder -D
yarn add electron-updater
package.json里做参数配置
看build参数，各个参数对照着官方文档

</script>执行升级
执行yarn build之后，会生成安装包 和 yml文件
yml文件是内部做检测更新使用
version: 1.0.0

releaseDate: '2023-11-05T08:56:32.685Z'我们需要把这三个文件放在 对象存储服务器上
只要提供的更新地址拼接上 latest-mac.yml文件的 可以访问到就可以
这样就可以做更新了
如果做测试，本地启动一个服务
//更新连接autoUpdater.setFeedURL('http://127.0.0.1:5500/build')
这里指向本地就可以，打包生层的文件放在build目录下 一样测试
