Context isn’t for cancellation | Dave Cheney
This is an experience report about the use of, and difficulties with, the context.Context facility in Go. Many authors, including myself, have written about the use of, misuse of, and how they would change, context.Context in a future iteration of Go. While opinions differs on many aspects of context.Context, one thing is clear–there is almost unanimous agreement that the Context.WithValue method
Unit Testing Golang HTTP Middleware - Kyle Purdon - Medium
Unit-Testing Golang HTTP Middleware is simple, but a topic that is not well covered. This post covers an example http middleware including unit tests. Constructing and using idiomatic http middleware is a story that’s already been told. See this, this, or simply google it to learn more about the topic. Something you won’t find in that search is how to unit test http middleware in Golang. The examp

Writing HTTP Middleware in Go · Justinas StankeviÄius
In the context of web development, "middleware" usually stands for "a part of an application that wraps the original application, adding additional functionality". It's a concept that usually seems to be somewhat underappreciated, but I think middleware is great. For one, a good middleware has a single responsibility, is pluggable and self-contained. That means you can plug it in your app at the i
