oal-wasm

The Oxlip API Language

OAL is a high-level functional programming language for designing OpenAPI definitions. As an Interface Description Language, it is not general purpose. The motivation is to alleviate the pain of managing OpenAPI in JSON or YAML by hand and at scale. OAL defines algebraic abstractions over REST concepts, not too dissimilar to Sass/SCSS over CSS.

There are pros and cons to both API-design-first and OpenAPI generated from implementation. As OpenAPI is better produced or consumed by machines rather than humans, OAL tries to help API-design-first teams with better tooling.
