Better HTTP Server Routing in Go 1.22 — Back in May, we linked to a discussion about enhancing http.ServeMux’s routing capabilities. In July, it became a proposal, and now Eli Bendersky gives a practical example of what the new multiplexer can offer and compares it against gorilla/mux. Hacker News hosted an extensive discussion too, with debate over the pros and cons of having a panic occur when multiple routes match and the use of magic strings vs. verb-specific methods. Go 1.22 is expected in early 2024, so expect to see more on this topic before then.
