Are you folks using OpenAPI when developing API in Go?

What generators do you use?

Hi Alex,

Yes, I use OpenAPI all the time for doing API-first development in Go. This is the go-to generator currently, as far as I'm aware: https://github.com/oapi-codegen/oapi-codegen

It is very comprehensive, though in my opinion a bit configuration heavy and not quite strict enough.

I'm working on an alternative generator that is a bit more 'light-weight', but I don't have a timeline yet for when it will be available.

This is a cry for help! I cannot seem to go forward in my Go lessons. I am very stuck in APIs. As I do not have prior experience in this, it is so disheartening because this is something I need to learn

I briefly examined four approaches a while ago (https://appliedgo.net/spotlight/4-tools-for-generating-rest-apis/)—two spec-to-code and two code-to-spec approaches. I still found no time to run deeper experiments with any of them, though.

API-first, create specification, than generate all the code with ogen.

Generate models, controllers, etc. Fully compatible with std `http` lib.
