# Documentation Structure Template

## Code Snippet: User Authentication
**Source**: React Tutorial @12:34-15:20
**Language**: JavaScript (React 18.2.0)
**Context**: JWT implementation with secure storage

```javascript
// 由教程捕获；请与当前源码及API文档核对
const authenticateUser = async (credentials) => {
  try {
    const response = await fetch('/api/auth', {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify(credentials)
    });
    return await response.json();
  } catch (error) {
    console.error('认证失败:', error);
  }
};
```

**Visual Context**:
`![Authentication Flow Diagram](auth-flow-screenshot.png)`

<TutorialDocumentationCTA />

**Implementation Notes**:
- Requires CSRF token for production
- Error handling added for network failures
- Compatible with React 18+ concurrent features

#更站得住脚的技术工作流

目标并不是编造一个准确率或生产力百分比，而是得到一个其他开发者能够验证的结果。Google 的技术写作指南建议使用清晰的范围、合乎逻辑的大纲、基于任务的标题、渐进式披露、导航，以及指向更深入材料的链接。把这一标准应用到你的工作流中：保留教程 URL 和时间戳，记录语言与依赖版本，说明这段代码片段为什么存在，在一个小型、可复现的环境中运行它，并链接到相关的官方文档。把捕获到的代码视为起点。测试、类型检查、安全审查、许可检查，以及与当前上游 API 的对照，才是把教程片段转化为可维护项目知识的关键。
