Golang Panic Handler Middleware

Handling panic elegantly:

package main

import (
    "fmt"
    "log"
    "net/http"
)

func handle() http.HandlerFunc {
    return func(w http.ResponseWriter, r *http.Request) {
        panic("i am panic")
    }
}

func handlePanic(next http.HandlerFunc) http.HandlerFunc {
    return func(w http.ResponseWriter, r *http.Request) {
        defer func() {
            if i := recover(); i != nil {
                log.Printf("panic at %s: %v", r.URL.Path, i)
                w.WriteHeader(http.StatusInternalServerError)
                fmt.Fprint(w, http.StatusText(http.StatusInternalServerError))
            }
        }()

        next(w, r)
    }
}

func main() {
    http.ListenAndServe(":8000", handlePanic(handle()))
}
