api := rest.NewApi()

All 19 examples have been updated to use the new API. See here
V3 is about deprecating the ResourceHandler in favor of a new API that exposes the Middlewares. As a consequence, all the Middlewares are now public, and the new Api object helps putting them together as a stack. Some default stack configurations are offered. The router is now an App that sits on top of the stack of Middlewares. Which means that the router is no longer required to use Go-Json-Rest.
