Don’t return err in Go — akavel's digital garden
Instead, add missing details relevant for debugging. Some people like to complain that Go requires writing tons of “if err != nil { return err }†blocks. Those people don’t understand Go errors. The thing is, what they complain about is actually a completely wrong way of handling errors in Go: return err is an antipattern. Let me show what I mean on some sample code: a helper library for configuri

Matthew Sanabria - Start With the Go Standard Library
When starting a project, new Gophers often ask the following questions. What logger should I use? What web framework should I use? What object–relational mapping (ORM) should I use? These questions are well-intentioned but they all miss a key aspect about Go. Go has a great standard library. Let’s understand why. What is a Standard Library? A standard library is library of packages that are includ

Self-referential functions and the design of options
I've been trying on and off to find a nice way to deal with setting options in a Go package I am writing. Options on a type, that is. The package is intricate and there will probably end up being dozens of options. There are many ways to do this kind of thing, but I wanted one that felt nice to use, didn't require too much API (or at least not too much for the user to absorb), and could grow as ne
