| Using GraphQL SDL files as executable API Contracts | apidays New York 2025 | 2025-05-14 |
Uses GraphQL SDL files as executable API contracts with Specmatic to auto‑generate contract tests, mocks and backward‑compatibility checks; demos run from CLI… | ||
| API Design Anti-patterns: How to identify & avoid them | Agile India 2025 | 2025-03-25 |
Explains that Level 2 REST covers the 80/20 of HTTP APIs while Level 3 hypermedia is rare (PayPal, GitHub), and contrasts Postel’s robustness with Hyrum’s Law… | ||
| The Functional Fix: Kotlin Error Handling Made Elegant | Functional Conf 2025 | 2025-01-24 |
Refactors a procedural Kotlin HTTP-request matcher used in Specmatic into a Railway Oriented composition that returns an Either monad and chains via… | ||
