Hello, everyone!
What is the best way to generate OpenAPI docs basing on Ktor routings (already written)?
There`s Ktor OpenAPI Generator (https://github.com/papsign/Ktor-OpenAPI-Generator), but the project seems not very active.

[CLOVIS]

The only active project I know of is the Ktor plugin for IntelliJ, but it has a few limitations (you must have IDEA, and it won't work if you don't write your endpoints exactly as they are in the documentation, you can't generate with utility functions)

[aazavoykin]

Thank you, it`s an option!

I believe they added support for openapi in ktor v2.2 -> https://ktor.io/docs/openapi.html

[CLOVIS]

@Dariusz Kuc that's the plugin I mentioned.

I can vouch for https://github.com/bkbnio/kompendium
No intellij plugin needed, and no need to keep your openapi up to date manually since the api is inferred on runtime.

Thank you! I will try it too

@ESchouten It seems that with Kompendium we should describe our API with some DSL (and I will get schema based on these descriptions on some endpoint on runtime), but what I need is to generate schema based on existing routes (as json at some endpoint in runtime or as a file generated by some Gradle task). Do I miss something in Kompendium`s docs?

[CLOVIS]

It looks promising, but also quite verbose 🤔

I wrote a code generator for OpenApi, Swagger, WSDL, XSD that will be open sourced soon.
