How can I enable cors for a particular endpoint?

[0xsubi]

RIght now, I am doing

mux := http.NewServeMux()

mux.HandleFunc("/hello", handleHello)
// Other endpoints

c := cors.New(cors.Options{
		AllowedMethods:         []string{"GET"},
	})

	handler := c.Handler(mux)

	if err := http.ListenAndServe(":8080", handler); err != nil {
		log.Fatal("HTTP server error: ", err)
	}

This enables CORS for all the endpoints, but I want to do so for selective few

You should be able to just wrap your handler function c.Handler(handleHello) instead of wrapping the entire mux.

You can write like this for each method:

func YourMethod(w http.ResponseWriter, r *http.Request) {
  w.Header().Set("Context-Type", "application/x-www-form-urlencoded")
	w.Header().Set("Access-Control-Allow-Origin", "*")
	w.Header().Set("Access-Control-Allow-Methods", "DELETE")
	w.Header().Set("Access-Control-Allow-Headers", "Content-Type")
  json.NewEncoder(w).Encode(something)
}
