Last year, we explored how to design and document APIs with OpenAPI. This year, we’re going a step further—into the world of code generation.

In this advanced session, we’ll show you how to evolve your OpenAPI specs from static descriptions into powerful, reusable assets that generate SDKs, server stubs, tests, and more. But to get clean, usable code, your spec needs more than just endpoints—it needs structure, consistency, and intention.

Attendees will learn how to:

- Refactor your specs for codegen success (think: reusable components, enums, type safety)

- Avoid common pitfalls like vague schemas, circular refs, or overloaded responses

- Enforce consistency with style guides and automated linting

- Integrate your specs into CI/CD pipelines for validation and governance

- Generate tailored docs, SDKs, and test clients—automatically

- Balance automation vs control: When to let the generator do the work—and when to intervene

We’ll demo code generation tools in action (like OpenAPI Generator, NSwag, and Stoplight), and share real-world lessons from teams using OpenAPI across production systems. You’ll also get practical tips for integrating codegen into your API lifecycle and CI/CD workflows.

This session is perfect for developers, architects, and technical writers ready to take their OpenAPI game to the next level—turning documentation into real, usable code.
