Crafting Great APIs with Domain-Driven Design
summary
Claims a repeatable workshop sequence that turns business workflows into APIs by combining Domain Stories, a Visual Glossary, Wardley mapping, Event Storming and an API Product Canvas. Uses Miro boards exported to PDF, then LLMs or Cloud Code to generate starter OpenAPI/AsyncAPI specs. Demonstrates with a donation-funded online library: catalog management as a bounded context, search endpoints, async events for reading-list updates, and a path to anti-corruption layers and implementation guidance. Emphasizes synchronous and asynchronous design, quality requirements, and iterative versioning.
