One of the firsts ones you’ll encounter is: How do I even find a Go project to contribute to? This writeup will help you find the right issue for you, in a Go project you can get excited about! An Endless Stream of Issues The GitHub advanced search is a great source of various first-time suitable issues! https://gopherdojo.com/handler-vs-handlerfunc/ Fri, 22 Mar 2024 00:00:00 +0000 https://gopherdojo.com/handler-vs-handlerfunc/ Confused by seeing references to Handler and HandlerFunc in Go code? Here is all you need to know to understand how they relate to each other and which one to use. Handler Handler is an interface. You can see the complete definition in the documentation: type Handler interface { ServeHTTP(ResponseWriter, *Request) } Whatever provides a ServeHTTP function satisfies the Handler interface! To satisfy this interface, you could write your own struct which has the function signature required. https://gopherdojo.com/go-folder-structure/ Tue, 29 Jan 2019 00:00:00 +0000 https://gopherdojo.com/go-folder-structure/ Before getting back into developing professionally in Golang last year, I had so many questions: What tools are useful? What nuances am I missing? What patterns are popular? How to design testable applications? What libraries are helpful when creating RESTful APIs? How to make friends with interfaces and the Go-way of doing things? Good ol’ A Tour of Go helped with the first one. The other ones took a bit of searching, watching talks, looking at projects and asking questions. https://gopherdojo.com/go-json-omitempty/ Wed, 21 Nov 2018 00:00:00 +0000 https://gopherdojo.com/go-json-omitempty/ When working with JSON in Go recently, I wondered: “What the heck does json:omitempty do?”. I was looking for ways to handle missing fields while unmarshalling some JSON into a struct, and got confused for a while. Here are a few examples, as a reminder how most of it works. Those are not fancy edgecases. Those are self-contained, completely functional code snippets which should be easy to follow. You’re welcome future-me. https://gopherdojo.com/switch-to-go-modules/ Wed, 14 Nov 2018 00:00:00 +0000 https://gopherdojo.com/switch-to-go-modules/ Go modules! Finally you don’t have to place your code into the directory structure imposed by GOPATH! Also, you don’t need to set up external tooling, such as Godep, to manage your project’s dependencies. All you need is to use Go in the version 1.11+ and you’re set. Well, not quite. Before you can start enjoying modules, you need to make the switch to them, or init your fresh new project to use them.
