本项目由四个 repo，共计三个后端、一个前端、三个客户端组成。
This project consists of four repositories, which consists of three backends, one frontend, and three clients in total.
- 给教师和学生使用的 Panel 的前端和后端，技术栈分别为 Vue3 + vite + TypeScript 和 Node.js + Express.js + Sequelize + TypeScript
- The frontend and backend for the panel used by teachers and students are built with Vue3 + Vite + TypeScript and Node.js + Express.js + Sequelize + TypeScript, respectively. You can find the frontend here and the backend here.
- 用于控制、推流工控摄像头的工控机客户端和后端，技术栈分别为 Node.js + JS (JSDoc) + ffmpeg (HLS) 和 Node.js + Express.js + Sequelize + TypeScript
- The client and backend for controlling and streaming industrial cameras are developed using Node.js + JS (JSDoc) + ffmpeg (HLS) and Node.js + Express.js + Sequelize (MySQL) + TypeScript, respectively. You can access the client repository here and the backend here.
- 用于在浏览器中远程控制电脑的远程桌面客户端、被控客户端和后端。其中远程桌面客户端修改自开源项目 rustdesk，并继续以 AGPL 协议开源；被控客户端技术栈为 Node.js + JS (JSDoc)，后端技术栈为 Node.js + Express.js + Sequelize + TypeScript
- The remote desktop client, controlled client, and backend for remotely controlling computers in a web browser are available at the following links: Remote Desktop Client, Controlled Client, and Backend. The remote desktop client is a modified version of the open-source project RustDesk, which remains open source under the AGPL license. The controlled client is developed using Node.js + JS (JSDoc), and the backend utilizes Node.js + Express.js + Sequelize + TypeScript.
全量引入了 type check，对 JS 也使用了 JSDoc 标注类型和 @ts-check 检查类型，以尽可能减少运行时错误。
Strong type checking is implemented throughout the project, including the use of JSDoc for annotating types and @ts-check for type checking, aiming to minimize runtime errors as much as possible. You can find some interesting type functions here.
