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"
    "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.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)
}
