# Project Instructions
|
|||
|
|
|
|||
|
|
This file provides context for AI assistants working on this project.
|
|||
|
|
|
|||
|
|
## Project Type: Go
|
|||
|
|
|
|||
|
|
### Commands
|
|||
|
|
- Build: `go build`
|
|||
|
|
- Test: `go test ./...`
|
|||
|
|
- Run: `go run .`
|
|||
|
|
- Format: `go fmt ./...`
|
|||
|
|
|
|||
|
|
### Version Control
|
|||
|
|
This project uses Git. See .gitignore for excluded files.
|
|||
|
|
|
|||
|
|
## Guidelines
|
|||
|
|
|
|||
|
|
- Follow existing code style and patterns
|
|||
|
|
- Write tests for new functionality
|
|||
|
|
- Keep changes focused and atomic
|
|||
|
|
- Document public APIs
|
|||
|
|
- **防御式编程**: 所有函数返回 error 不许直接 `_` 忽略，必须日志告警或向上抛出
|
|||
|
|
- **校验前置**: 外部输入（接口参数、PLC 信号地址、配置值）在边界处做合法性校验，防止非法参数进入内部逻辑
|
|||
|
|
|
|||
|
|
## Frontend Build
|
|||
|
|
|
|||
|
|
前端代码位于 `frontend/` 目录，使用 Vite + React + TypeScript。
|
|||
|
|
|
|||
|
|
### 构建流程
|
|||
|
|
|
|||
|
|
1. `cd frontend && npm run build` — 前端构建，输出到 `frontend/dist/`
|
|||
|
|
2. 将 `frontend/dist/*` 复制到 `public/`（`public/` 在 `.gitignore` 中，不提交到 git）
|
|||
|
|
3. `go build` — Go 通过 `//go:embed public` 将 `public/` 嵌入二进制
|
|||
|
|
|
|||
|
|
### 构建脚本
|
|||
|
|
|
|||
|
|
- **macOS/Linux:** `./build.sh`
|
|||
|
|
- **Windows:** `build.bat`
|
|||
|
|
|
|||
|
|
### 注意事项
|
|||
|
|
|
|||
|
|
- `vite.config.ts` 不得设置 `build.outDir`，保持 Vite 默认行为（输出到 `dist/`）
|
|||
|
|
- `public/` 是纯构建产物，不与 `frontend/public/`（Vite 静态资源目录）混淆
|
|||
|
|
- 开发时前端通过 `npm run dev` 独立运行，Vite proxy 代理 API 请求到 Go 后端
|
|||
|
|
|
|||
|
|
## Important Notes
|
|||
|
|
|
|||
|
|
- **每次对话开始时，必须先读取 `agent约束.md`**。该文件包含项目架构、代码规范、启动顺序、数据流等核心约束，是 AI 辅助开发的最高优先级参考文档。
