This is a write-up of a talk I gave at the Gotham Go conference in 2018. It won’t be identical to the talk, but should cover the same topics and convey the same message. Whenever the videos from the conference are posted online I’ll also link to it from here. Slides from this talk can be found here. What is Gophercises? Gophercises is a free course I created that is composed of mini-exercises to help budding Gophers (Go developers) practice writing Go code and gain familiarity with different aspects of the language.

A common misconception is that a JSON API is vastly different from a web application that renders server-side HTML. In this article we explore how to convert an HTML-based web app into a JSON API in order to demonstrate how similar the two really are in a well designed app.

An incredibly common question I get when helping people learn web development is, "Why can’t I pass this handler function into a function that expects an http.Handler?" It is a logical question. The compiler can automatically convert those functions into the http.HandlerFunc type, so why can't it take the next step and infer that it also implements the Handler interface? Learn why (and more) in this article!

I was lucky enough to be invited onto the popular Go Time to discuss things like Gophercises, experiencing the joy programming, and more. If you want to check it out you can use the widget below to listen, visit the website (https://changelog.com/gotime/74) to download an MP3, and lastly you can probably find the episodes anywhere else you typically consume podcasts (I have only verified Go Time is on Google Music and Apple Music).

I want to describe a scenario where there currently isn’t a good solution in Go (at least that I am aware of). Let’s say you have something like the template.Template type with methods like Template.Funcs: type Template struct { *parse.Tree // contains filtered or unexported fields } func (t *Template) Funcs(funcMap FuncMap) *Template If we wanted to use an interface for this type, it is impossible to express in Go now.
