Content-Type: "application/msgpack"

MessagePack is an efficient binary serialization format. It lets you exchange data among multiple languages like JSON. But it's faster and smaller. Small integers are encoded into a single byte, and typical short strings require only one extra byte in addition to the strings themselves.

The Context.MsgPack(v) is the method which sends MessagePack responses to the client. It accepts any Go value. As always, if it's a struct value, the fields should be exported.

type Data struct {
Message string `msgpack:"message"`
func handler(ctx iris.Context) {
response := Data{Message: "a message"}
