Handling the endpoint for updating an event in go-rest-api

main.go

func updateEvent(w http.ResponseWriter, r *http.Request) {
	eventID := mux.Vars(r)["id"]
	var updatedEvent event

	reqBody, err := ioutil.ReadAll(r.Body)
	if err != nil {
		fmt.Fprintf(w, "Kindly enter data with the event title and description only in order to update")
	}
	json.Unmarshal(reqBody, &updatedEvent)

	for i, singleEvent := range events {
		if singleEvent.ID == eventID {
			singleEvent.Title = updatedEvent.Title
			singleEvent.Description = updatedEvent.Description
			events = append(events[:i], singleEvent)
			json.NewEncoder(w).Encode(singleEvent)
		}
	}
