Name string
Email string
}{
Name: "Bill",
Email: "[email protected]",
}
rw.Header().Set("Content-Type", "application/json")
rw.WriteHeader(200)
json.NewEncoder(rw).Encode(&u)
}

package main
import (

func main() {
handlers.Routes()
log.Println("listener : Started : Listening on :4000")
http.ListenAndServe(":4000", nil)
}
