go-chi/chi is

a lightweight, idiomatic and composable router for building Go HTTP services.


  1. Chain httpin.NewInput middleware with chi.With method
  2. Enable path Directive by using chi.URLParam Method

Run Demo

package main

import (


type ListUserReposInput struct {
Username string `in:"path=username"`
Visibility string `in:"query=visibility"`
Fork bool `in:"query=fork"`

func ListUserRepos(rw http.ResponseWriter, r *http.Request) {
// Retrieve you data in one line of code!
input := r.Context().Value(httpin.Input).(*ListUserReposInput)

fmt.Printf("input: %#v\n", input)

func init() {
// Register a directive named "path" to retrieve values from `chi.URLParam`,
// i.e. decode path variables.
httpin.UseGochiURLParam("path", chi.URLParam)

func main() {
router := chi.NewRouter()

// Bind input struct with handler.
).Get("/users/{username}/repos", ListUserRepos)

r, _ := http.NewRequest("GET", "/users/ggicci/repos?visibility=public&fork=1", nil)

rw := httptest.NewRecorder()
router.ServeHTTP(rw, r)
