AI Prompt: Generate API Documentation from Code Comments

- 06.06.26 - ErcanOPAK

📚 Turn // Comments into Beautiful Documentation

JSDoc, XML comments, docstrings are structured. AI converts comments to Markdown docs. Publish anywhere.

📝 The Prompt

Convert these code comments into API documentation:

[Paste code with JSDoc/XML comments here]

Requirements:
- Generate readable Markdown
- Include function signatures with types
- Add example usage for each function
- Group by class/module
- Add table of contents
- Highlight deprecated methods
- Show parameter details (name, type, description)
- Show return values and possible exceptions

Output format: GitHub Flavored Markdown
Language: English, technical but accessible

Example JSDoc:
/**
 * Fetches user data by ID
 * @param {number} userId - User identifier
 * @param {boolean} [includeOrders=false] - Include user orders
 * @returns {Promise<User>} User object
 * @throws {NotFoundError} If user doesn't exist
 */

✅ Example Output

## UserAPI

### fetchUser(userId, includeOrders = false)

Fetches user data by ID from the database.

**Parameters:**
- `userId` (number, required) - User identifier (must be positive)
- `includeOrders` (boolean, optional) - Include user orders in response. Default: false

**Returns:** `Promise<User>` - User object with id, name, email

**Throws:** `NotFoundError` - When user doesn't exist

**Example:**
```javascript
import { fetchUser } from './api';

try {
  const user = await fetchUser(123, true);
  console.log(user.name, user.orders);
} catch (err) {
  if (err instanceof NotFoundError) {
    console.log('User not found');
  }
}
```

💡 Use Cases

  • Generate README from JSDoc comments
  • Create wiki pages for internal APIs
  • Document legacy code with minimal comments
  • Generate Postman collections from OpenAPI comments

“Code had JSDoc but no external docs. AI converted to Markdown in 2 minutes. Published to GitHub wiki. Developers finally know how to use the API.”
