Hi. Does Http4k actually generate the `openapi.yml` file somewhere? If not, is it possible to make it to do so?

it's purposely dynamic in order that you can generate it at runtime. For the times when we actually need it, we always just write a test which calls the openapi endpoint and outputs the content to a file somewhere.

A lot of the time we use this for approval testing (to lock in the contract) and to export it for other uses like generating clients etc...

The `openapi` is in the `json` format. Is there a way, out-of-the-box to have it as `yaml` ?

sorry - you'll need to convert it manually to what is undoubtedly a worse format :wink: . Should be easy in a test though - you can use jackson YAML and jackson JSON to do it
