OpenAPI, which was formerly called Swagger, is a set of specifications to encode the server API endpoints definitions into text, mostly JSON.
From this reference text, you can generate client code to access the service, in a vast number of languages.
Delphi seems to be far behind other languages, in terms of this code generation. I found nothing even working for FPC.
Since we needed it for our internal tools at Tranquil IT, we just published the new mormot.net.openapi.pas Open Source unit, which is quite a game changer. Thanks Andreas for starting this project, and testing it in its early age!
