In Go 1.22 the ServeMux was updated to be significantly easier to use for building web applications. Supported was added for HTTP methods, variables in URL paths, and more. In this article we discuss how it stacks up to some third party libraries that have existed in the Go ecosystemf or a while.
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.
