Generate Elixir API from Swagger / OpenAPI 3.0

Hi all. I’ve seen plenty of information about generating Swagger docs from a pre-existing Phoenix API. Has anyone come across a tool that has the ability to generate a Phoenix API from a Swagger / OpenAPI 3.0 specification? I’ve had a look at Swagger’s Codegen tool but it doesn’t support building server stubs for Elixir. Thank you :slight_smile:

Update:. The library is on its way. I’m currently refactoring the JSONschema stuff to be easier to debug

I’m still stuck on unevaluatedProperties, but I’m very close. UnevaluatedItems should fall soon after. Sorry, this is an incredibly hard part of JSONschema to compile correctly.

But as a teaser, this is the performance improvement for one of the JSONschema tests ($ref)

To give some perspective. It is also difficult to keep this in sync with the openapi spec over time. Also, the generators get old very fast. From my experience from using this in java. We had more trouble with the generator. Instead, we built it manually and programmed unit tests to check that the implementation is in sync with the openapi spec.

And also the spec is quite complex as this is using all features json-schema has to offer.
