This package provides a drop-in replacement for net/http's ListenAndServe for use in an AWS Lambda invoked by a ALB

func main() {
http.HandleFunc("/", hello)
log.Fatal(gateway.ListenAndServe(":3000", nil))
}
func hello(w http.ResponseWriter, r *http.Request) {
// example retrieving values from the api gateway proxy request context.
_, ok := gateway.RequestContext(r.Context())
if !ok {
fmt.Fprint(w, "Hello World from Go")
return
}
fmt.Fprintf(w, "Hello %s from Go", r.RemoteAddr)
