背景
因为搞嵌入式开发的时候，每次烧写不同版本的固件的时候，经常需要重命名,有时候烧错版本我也不知道；
因此我认为对固件的管理比较麻烦，所以我希望能够有一个比较好的工具来做管理，找了一圈没有发现合适的，因此我决定自己搞。
找了一些界面设计的框架，QT 和 Electron 都不错。但是因为 搞嵌入式不能总是只会 C/C++，还是要懂点其他语言（哪怕是脚本）。
因此，我决定勇敢地迈出web的第一步。
介绍
总结：Electron是用于跨平台的桌面开发的框架，能够以web的形式设计界面。
大家感话：
-
Electron 是一个使用 JavaScript, HTML 和 CSS 等 Web 技术创建原生程序的框架，它负责比较难搞的部分，你只需把精力放在你的应用的核心上即可。
-
Electron相当于一个浏览器的外壳，可以把网页程序嵌入到壳里面，可以运行在桌面上的一个程序，可以把网页打包成一个在桌面运行的程序（软件）。
安装
nodejs
环境要求 v10.0 以上
首先进入node.js官网[https://nodejs.org/en/]下载node.js，并安装。
因为等待的时间会有点久，因此可以先将官方提供的例程给先clone下来，或者下载：
git clone https://github.com/electron/electron-api-demos
安装时的路径最好不要带有中文或者是空格，node验证安装情况：
node -v
v14.15.1
Electron
输入以下命令安装：
npm config set registry https://registry.npm.taobao.org/ # 设置npm镜像源为淘宝镜像
npm install -g electron # 进行全局安装
npm install -g electron-packager
输出结果：
C:UsersSchipsAppDataRoaming

查看electron是否安装成功可通过命令electron -v查看。
可选的权限配置
reference：https://blog.csdn.net/weixin_38883338/article/details/100054550
注意，因为权限的问题，运行Electron可能会出现以下结果：
electron : 无法加载文件 C:UsersSchipsAppDataRoaming
pmelectron.ps1，因为在此系统上禁止运行脚本。有关详细信息，请
参阅 https:/go.microsoft.com/fwlink/?LinkID=135170 中的 about_Execution_Policies。

解决方法：以管理员权限运行cmd或powershell，输入set-ExecutionPolicy RemoteSigned，按y回车
set-ExecutionPolicy RemoteSigned
执行策略更改
执行策略可帮助你防止执行不信任的脚本。更改执行策略可能会产生安全风险，如 https:/go.microsoft.com/fwlink/?LinkID=135170

运行Electron例程
通过运行Electron例程来验证效果（上文已经提到提前下载）：
git clone https://github.com/electron/electron-api-demos
根据例程提供的文档，输入下列的命令：
cd electron-api-demos
npm install
npm start
运行结果如下：
PS C:cygwin64homeSchipselectron-api-demos> npm install

使用electron-builder打包
使用之前需要先安装yarn：
拓展阅读：
yarn是什么？简单来说是和npm一样的包管理工具，并对npm的一些弊端提供了优化和解决方案
yarn和npm的区别？安装速度更快，缓存了每个下载过的包，再次使用时无需重复下载。 同时利用并行下载以最大化资源利用率，
运行代码前会校验每个安装包的完整性和统一性，使其在不同系统上也能无差别的工作
官方推荐使用yarn的原因：
1、它可以更好地处理依赖关系。
2、可以使用 yarn clean 帮助减少最后构建文件的大小。
