+# Repository Guidelines
+
+## Project Structure & Module Organization
+This repository is split into two apps:
+- `mengyaping-frontend/`: React + Vite UI. Main code is in `src/` (`components/`, `pages/`, `hooks/`, `services/`), with static assets in `public/`.
+- `mengyaping-backend/`: Go + Gin API and monitor service. Core folders are `handlers/`, `services/`, `router/`, `models/`, `storage/`, `config/`, and `utils/`.
+
+Runtime data is persisted under `mengyaping-backend/data/` (`websites.json`, `records.json`, `groups.json`, `config.json`). Keep data format changes backward-compatible.
+
+## Build, Test, and Development Commands
+Frontend (run inside `mengyaping-frontend/`):
+- `npm install`: install dependencies.
+- `npm run dev`: start Vite dev server.
+- `npm run build`: create production build in `dist/`.
+- `npm run lint`: run ESLint checks.
+
+Backend (run inside `mengyaping-backend/`):
+- `go mod tidy`: sync Go modules.
+- `go run main.go`: start API server (default `0.0.0.0:8080`).
+- `go test ./...`: run all backend tests.
+- `docker compose up -d --build`: build and run containerized backend.
+
+## Coding Style & Naming Conventions
+- Frontend: 2-space indentation, ES module imports, React component files in PascalCase (for example `WebsiteCard.jsx`), hooks in `useXxx.js`, utility/service functions in camelCase.
+- Backend: format with `gofmt`; keep package names lowercase; exported identifiers in PascalCase, internal helpers in camelCase.
+- Keep handlers thin and place business logic in `services/`.
+
+## Testing Guidelines
+There are currently no committed frontend tests and minimal backend test coverage. Add tests for every non-trivial change:
+- Backend: `*_test.go` next to implementation; focus on handlers and service logic.
+- Frontend: if introducing test tooling, prefer Vitest + Testing Library with `*.test.jsx` naming.
+
+## Commit & Pull Request Guidelines
+Current history uses short, imperative commit text (for example `first commit`). Continue with concise, scoped messages such as:
+- `feat(frontend): add status filter`
+- `fix(backend): validate monitor interval`
+
+Each PR should include:
+- Clear summary and impacted area (`frontend`, `backend`, or both).
+- Validation steps and commands run.
+- Screenshots/GIFs for UI changes.
+- Linked issue/ticket when available.
+
+## Security & Configuration Tips
+- Do not commit secrets, tokens, or private endpoints.
+- Frontend dev API target is `http://localhost:8080/api` in `mengyaping-frontend/src/services/api.js`.
+- Commit only sanitized sample data in `mengyaping-backend/data/`.

+# 萌芽Ping（MengYaPing）
+
+一个轻量、可自部署的网站可用性监控面板。  
+支持多网站/多 URL 监控、分组管理、实时状态查看、24h/7d 可用率统计与延迟展示。
+
+## 功能特性
+
+- 多网站监控：每个网站可配置多个 URL，分别检测
+- 自动巡检：默认每 5 分钟检测一次（可配置）
+- 状态面板：在线/离线、状态码、响应延迟、最后检测时间
+- 可用率统计：按 24 小时与 7 天维度聚合
+- 分组与检索：支持分组筛选与关键词搜索
+- 手动触发：支持单网站“立即检测”
+
+## 技术栈
+
+- 前端：React 19 + Vite 7 + Tailwind CSS 4
+- 后端：Go 1.25 + Gin
+- 存储：本地 JSON 文件（`mengyaping-backend/data/`）
+- 部署：Docker / Docker Compose（后端）
+

+```
+
+## 快速开始（本地开发）
+
+### 1) 启动后端
+
+```bash
+cd mengyaping-backend
+go mod tidy
+go run main.go
+```
+
+默认地址：`http://localhost:8080`
+
+### 2) 启动前端
+
+```bash
+cd mengyaping-frontend
+npm install
+npm run dev
+```
+
+前端开发地址通常为：`http://localhost:5173`
+
+## 常用命令
+
+```bash
+# 前端
+cd mengyaping-frontend
+npm run dev      # 开发模式
+npm run build    # 生产构建
+npm run lint     # 代码检查
+
+# 后端
+cd mengyaping-backend
+go test ./...    # 运行测试
+```
+
+Windows 用户也可直接使用仓库根目录下的 `开启前端.bat`、`开启后端.bat`、`构建前端.bat`。
+
+## API 概览
+
+基础前缀：`/api`
+
+- `GET /health`：健康检查
+- `GET /websites`：获取全部网站状态
+- `GET /websites/:id`：获取单网站状态
+- `POST /websites`：创建网站
+- `PUT /websites/:id`：更新网站
+- `DELETE /websites/:id`：删除网站
+- `POST /websites/:id/check`：立即检测
+- `GET /groups`：获取分组
+- `POST /groups`：新增分组
+
+## 配置说明
+
+后端支持环境变量配置（如 `SERVER_PORT`、`MONITOR_INTERVAL`、`MONITOR_TIMEOUT` 等），并会读取 `mengyaping-backend/data/config.json`。  
+当前实现中，`config.json` 的值会覆盖环境变量同名项。
+
+## Docker 部署（后端）
+
+```bash
+cd mengyaping-backend
+docker compose up -d --build
+```
+
+`docker-compose.yml` 默认映射端口 `6161 -> 8080`。
+
+## 展示建议（GitHub）
+
+- 建议在仓库中新增 `docs/images/` 并放置页面截图
+- 可在本 README 顶部补充截图、动图或在线演示链接，提升展示效果
