+## Using nvm from postCreateCommand or another lifecycle command
+
+Certain operations like `postCreateCommand` run non-interactive, non-login shells. Unfortunately, `nvm` is really particular that it needs to be "sourced" before it is used, which can only happen automatically with interactive and/or login shells. Fortunately, this is easy to work around:
+
+Just can source the `nvm` startup script before using it:
+
+```json
+"postCreateCommand": ". ${NVM_DIR}/nvm.sh && nvm install --lts"
+```
+
+Note that typically the default shell in these cases is `sh` not `bash`, so use `. ${NVM_DIR}/nvm.sh` instead of `source ${NVM_DIR}/nvm.sh`.
+
+Alternatively, you can start up an interactive shell which will in turn source `nvm`:
+
+```json
+"postCreateCommand": "bash -i -c 'nvm install --lts'"
+```
+
+
+
+## OS Support
+
+Debian/Ubuntu, RedHat Enterprise Linux, Fedora, Alma, and Rocky Linux distributions with the `apt`, `yum`, `dnf`, or `microdnf` package manager installed.
+
+**Note**:  RedHat 7 Family (RedHat, CentOS, etc.) must use Node versions less than 18 due to its system libraries and long-term support (LTS) policies.
+
+`bash` is required to execute the `install.sh` script.

+## Options
+
+| Options Id | Description | Type | Default Value |
+|-----|-----|-----|-----|
+| version | Select or enter a Node.js version to install | string | lts |
+| nodeGypDependencies | Install dependencies to compile native node modules (node-gyp)? | boolean | true |
+| nvmInstallPath | The path where NVM will be installed. | string | /usr/local/share/nvm |
+| pnpmVersion | Select or enter the PNPM version to install | string | latest |
+| nvmVersion | Version of NVM to install. | string | latest |
+| installYarnUsingApt | On Debian and Ubuntu systems, you have the option to install Yarn globally via APT. If you choose not to use this option, Yarn will be set up using Corepack instead. This choice is specific to Debian and Ubuntu; for other Linux distributions, Yarn is always installed using Corepack, with a fallback to installation via NPM if an error occurs. | boolean | true |

+# 🚀 Node.js Hello World 项目
+
+一个功能完整的 Node.js Hello World 应用，展示了基本的 HTTP 服务器创建、路由处理和响应返回。
+
+## ✨ 特性
+
+- 🌐 内置 HTTP 服务器
+- 🎨 美观的 HTML 界面
+- 📡 RESTful API 端点
+- 🔧 完整的 JSDoc 注释
+- 🚀 优雅的服务器关闭处理
+- 📱 响应式设计
+- 🌍 中文界面支持
+
+## 🛠️ 技术栈
+
+- **Node.js** - JavaScript 运行时
+- **原生 HTTP 模块** - 无需额外依赖
+- **ES6+ 语法** - 现代 JavaScript 特性
+- **JSDoc** - 代码文档注释
+
+## 📋 系统要求
+
+- Node.js 14.0.0 或更高版本
+- npm 或 yarn 包管理器
+
+## 🚀 快速开始
+
+### 1. 克隆项目
+
+```bash
+git clone <your-repository-url>
+cd node-hello-world
+```
+
+### 2. 安装依赖
+
+```bash
+# 使用 npm
+npm install
+
+# 或使用 yarn
+yarn install
+
+# 或使用 pnpm
+pnpm install
+```
+
+### 3. 启动应用
+
+```bash
+# 生产环境启动
+npm start
+
+# 开发环境启动（支持热重载）
+npm run dev
+```
+
+### 4. 访问应用
+
+打开浏览器访问 [http://localhost:3000](http://localhost:3000)
+
+## 📡 API 端点
+
+| 端点 | 方法 | 描述 | 响应格式 |
+|------|------|------|----------|
+| `/` | GET | 主页面，显示项目信息和状态 | HTML |
+| `/api/hello` | GET | 返回 Hello World 消息 | JSON |
+| `/api/status` | GET | 返回服务器状态信息 | JSON |
+
+### API 响应示例
+
+#### GET /api/hello
+```json
+{
+  "message": "Hello World!",
+  "timestamp": "2024-01-01T00:00:00.000Z",
+  "language": "zh-CN"
+}
+```
+
+#### GET /api/status
+```json
+{
+  "status": "running",
+  "uptime": 123.456,
+  "memory": {
+    "rss": 12345678,
+    "heapTotal": 12345678,
+    "heapUsed": 12345678,
+    "external": 123456
+  },
+  "platform": "linux",
+  "nodeVersion": "v18.17.0"
+}
+```
+
+## 🎯 项目结构
+
+```
+node-hello-world/
+├── index.js          # 主应用文件
+├── package.json      # 项目配置和依赖
+├── README.md         # 项目说明文档
+└── .devcontainer/    # Dev Container 配置
+    └── devcontainer-node-20.json
+```
+
+## 🔧 开发
+
+### 可用的 npm 脚本
+
+```bash
+npm start      # 启动应用
+npm run dev    # 开发模式启动（支持热重载）
+npm test       # 运行测试（待实现）
+```
+
+### 环境变量
+
+| 变量名 | 默认值 | 描述 |
+|--------|--------|------|
+| `PORT` | `3000` | 服务器监听端口 |
+
+### 开发模式
+
+开发模式使用 `nodemon` 实现热重载，当你修改代码时，服务器会自动重启：
+
+```bash
+npm run dev
+```
+
+## 🐳 Docker 支持
+
+项目包含 Dev Container 配置，可以在 VS Code 或 GitHub Codespaces 中直接运行：
+
+1. 安装 VS Code 的 Dev Containers 扩展
+2. 在项目根目录按 `Ctrl+Shift+P`（或 `Cmd+Shift+P`）
+3. 选择 "Dev Containers: Reopen in Container"
+4. 等待容器构建完成
+
+## 📝 代码规范
+
+- 使用 JSDoc 注释规范
+- 遵循 ESLint 规则
+- 使用 Prettier 进行代码格式化
+- 支持 TypeScript 类型检查
+
+## 🧪 测试
