An exciting proposal is set to be included in Go 1.22, which will enhance the pattern-matching capabilities of the default HTTP serving multiplexer in the net/http package. The current multiplexer lacks advanced matching abilities, leading to the development of various third-party libraries. The new multiplexer in Go 1.22 aims to bridge this gap by providing advanced matching features. This article introduces the new multiplexer and compares it with gorilla/mux. It also provides usage examples and highlights new features such as specifying HTTP methods explicitly and using wildcards for pattern matching. The article concludes by stating that the improved standard library is a positive change for the Go community.
