go-chi/chi

go-chi/chi is

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

Integrations

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

Run Demo

package main

import (
	"fmt"
	"net/http"
	"net/http/httptest"

	"github.com/ggicci/httpin"
	httpin_integration "github.com/ggicci/httpin/integration"
	"github.com/go-chi/chi/v5"
)

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_integration.UseGochiURLParam("path", chi.URLParam)
}

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

	// Bind input struct with handler.
	router.With(
		httpin.NewInput(ListUserReposInput{}),
	).Get("/users/{username}/repos", ListUserRepos)

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

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