Storing data in a context.Context, or as I refer to it - using context values, is one of the most contentious design patterns in Go. Storing values in a context appears to be fine with everyone, but what specifically should be stored as a context value receives a lot of heated discussion. I’ll be honest - when I started using them I used them in the naive and somewhat inappropriate way that everyone complains about.
This article covers how to use the http.ServeMux provided by Go's standard libary in order to apply middleware to specific path prefixes (eg /dashboard/*) while ensuring the middleware isn't run on other paths.
