Routing without Frameworks

Go's http.ServeMux is a simple router. For microservices, you often want more control.

Creating a Mux:

go mux := http.NewServeMux() mux.HandleFunc("/users", userHandler) mux.HandleFunc("/products", productHandler)

http.ListenAndServe(":8080", mux)

Avoid using the global http.DefaultServeMux in production to prevent unexpected side effects from third-party packages.
