We can now produce not only the basic routes from the net/http package but more complicated ones using the Gorilla toolkit. By utilizing Gorilla, we can now create regular expressions and implement pattern-based routing and allow much more flexibility to our routing patterns.

With this increased flexibility, we also have to be mindful of errors now, so we've looked at handling error-based redirects and messages, including a custom 404, Page not found message to produce more customized error messages.

Now that we have the basics down for creating endpoints, routes, and handlers; we need to start doing some non-trivial data serving.

In Chapter 3, Connecting to Data, we'll start getting dynamic information from databases, so we can manage data in a smarter and more reliable fashion. By connecting to a couple of different, commonly-used databases, we'll be able to build robust, dynamic, and scalable web applications.
