Concise guide to golang/dep

Overview

This gist is based on the information available at golang/dep, only slightly more terse and annotated with a few notes and links primarily for my own personal benefit. It's public in case this information is helpful to anyone else as well.

I initially advocated Glide for my team and then, more recently, vndr. I've also taken the approach of exerting direct control over what goes into vendor/ in my Dockerfiles, and also work from isolated GOPATH environments on my system per project to ensure that dependencies are explicitly found under vendor/.

At the end of the day, vendoring (and committing vendor/) is about being in control of your dependencies and being able to achieve reproducible builds. While you can achieve this manually, things that are nice to have in a vendoring tool include:

##
## HTTP Router benchmarks -- August 31st, 2017 running Go 1.9.0
##
## This benchmark suite is based on https://github.com/julienschmidt/go-http-routing-benchmark
## using the most up-to-date version of each pkg as of today. Each router has their own
## pros and cons, so consider the designs of each router to suit your application.
