Using Functions Inside Go Templates In this tutorial we are going to cover how to use template functions like and, eq, and index to add some basic logic to our templates.

Controllers and Views in Go Chances are a lot of developers who pick up Go will be familiar with the MVC model. Models, views, and controllers are great for abstracting away code, but sadly there aren’t many examples of how to use them in Go. In this post I am going to go over how to get started with a basic controller and view in Go, and cover a really simple web application that uses them. While
