Yes, you can update existing OpenAPI docs. The tool supports both creating new documentation and maintaining existing files, ensuring your API specifications stay continuously in sync with your TypeScript codebase.

Yes, this OpenAPI generator works with Hono framework applications. After implementing API endpoints in your Hono application, it instantly generates corresponding OpenAPI 3.0.3 documentation ready for integration with Swagger UI.

Generating OpenAPI specifications from code adheres to strict Chinese OpenAPI writing standards. This ensures all documentation includes detailed business descriptions, accurate data models, comprehensive examples, and standardized error handling.

The best way to maintain API documentation accuracy in a TypeScript project is to automate it from your source code. This approach generates and updates OpenAPI 3.0.3 docs directly from your controller and service layers, preventing manual documentation drift.

Your API descriptions are out of sync with your service layer code because manual documentation easily drifts from implementation. Automating OpenAPI generation directly from TypeScript files ensures your specs accurately reflect your current endpoints and data models.
