How can I use Swagger UI with Ktor, any reference?

Swagger UI is generated from an OpenAPI specification, so you'd need to document your API as an OpenAPI spec, then you can generate the Swagger UI for it.

I think he meant if you can generate it from the Kotlin sources eg. by placing open api annotations on routes and stuff

Thanks for replying. I've checked the swagger website but I didn't find the solution. Does the swagger not support the Ktor yet officially?

If you're looking to generate the API spec from your existing API, try this: https://swagger.io/resources/articles/documenting-apis-with-swagger/#how-to-generate-openapi-from-existing-apis-7 Swagger Inspector should work with any API, regardless of implementation language.

It’s helpful to me. Thanks a lot.
