Enhancement - Add comments before routes for the Open API Spec

[khareyash05]

Hi ! I am in touch with this project from quite a while now and I had been reading about Open API recently. Would you like to OpenAPI-fy your project?

From my (limited) knowledge of Golang, there's no easy way to generate the Spec file without adding the comments before routes through the project.

Would it make sense to introduce something like this through the codebase so the file is auto generated?There would still be scope for error since the file isn't generated automatically from the code (which from what I can tell is not possible in Golang), but would make it slightly easier to track and make changes vs making them directly in the spec file.
