Design First: OpenApi and AsyncApi in Action!
summary
The talk explains using a Design-First workflow with OpenAPI for synchronous REST APIs and AsyncAPI for event-driven/asynchronous architectures. It shows, via a concrete example, how these specs keep documentation aligned with implementation, simplify consumer integration, enable standardized code generation, and support industrialization with modern tooling.
