package main

import (
   "net/http"

   "github.com/go-chi/chi"

   "github.com/alexisvisco/kcd"
)

func main() {
   r := chi.NewRouter()
   r.Get("/", kcd.Handler(YourHttpHandler, http.StatusOK))
   _ = http.ListenAndServe(":3000", r)
}

type Output struct {
   Name string `json:"name"`

}


func YourHttpHandler() (Output, error) {
   return Output{
      Name: "Hello world",
   }, nil
}

// Test it : curl 'localhost:3000'
