Opinion here: but I would not use a third-party package to implement validation. Maybe your example here is trivial and there will be more complex validation steps, but fighting a framework to do validation that you can trivially implement yourself and with way more granularity would be a better path IMHO.The Go programming language is an open source project to make programmers more productive.
