+# React + Vite
+
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+
+Currently, two official plugins are available:
+
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) for Fast Refresh
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
+
+## React Compiler
+
+The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend using TypeScript with type-aware lint rules enabled. Check out the [TS template](https://github.com/vitejs/vite/tree/main/packages/create-vite/template-react-ts) for information on how to integrate TypeScript and [`typescript-eslint`](https://typescript-eslint.io) in your project.
+
+## 环境变量配置
+
+本项目使用环境变量来配置 API 基础地址。
+
+### 配置说明
+
+1. 复制 `.env.example` 文件为 `.env`：
+   ```bash
+   cp .env.example .env
+   ```
+
+2. 编辑 `.env` 文件，设置您的 API 基础地址：
+   ```env
+   VITE_API_BASE_URL=http://your-api-server.com/api
+   ```
+
+3. 环境变量以 `VITE_` 开头才能在客户端代码中访问
+
+### 可用环境变量
+
+- `VITE_API_BASE_URL`: API 服务器的基础地址
+
+### 开发说明
+
+- 环境变量在开发服务器重启后生效
+- 生产环境部署时，请确保正确设置环境变量
