Build-Time OpenAPI Documentation in .NET 9: Insights from Mike Kistler
In a recent episode of #OneDevQuestion, Mike Kistler highlights his favorite OpenAPI feature introduced in .NET 9: build-time generation of OpenAPI documentation.
Key Points Discussed
- Build-Time Generation: .NET 9 now supports generating OpenAPI documentation as part of the build process. This eliminates the need for your application to serve the documentation at runtime.
- Local Usage: Developers can utilize the generated OpenAPI docs locally, facilitating tasks such as:
- Linting the API definition to ensure it conforms to best practices
- Code generation from the OpenAPI specification for clients or servers
- Applying tools like Spectral to enforce API design conventions
Benefits
- Performance and Security: By moving documentation serving out of the application, runtime overhead and potential exposure are reduced.
- Increased Flexibility: Local documentation files offer greater integration with CI/CD pipelines, linting, and external tools—improving the developer experience and code quality.
Tools Highlighted
- Spectral: A popular tool for linting OpenAPI (and other API formats) to enforce consistency and catch issues early.
