Before (use net/http)

After (use httpin)

func ListUsers(rw http.ResponseWriter, r *http.Request) { page, err := strconv.ParseInt(r.FormValue("page"), 10, 64) if err != nil { // Invalid parameter: page. return } perPage, err := strconv.ParseInt(r.FormValue("per_page"), 10, 64) if err != nil { // Invalid parameter: per_page. return } isMember, err := strconv.ParseBool(r.FormValue("is_member")) if err != nil { // Invalid parameter: is_member. return } // Do sth. }

type ListUsersInput struct { Page int `in:"query=page"` PerPage int `in:"query=per_page"` IsMember bool `in:"query=is_member"` } func ListUsers(rw http.ResponseWriter, r *http.Request) { input := r.Context().Value(httpin.Input).(*ListUsersInput) // Do sth. }

Why this package?

Items	Before (use net/http package)	After (use ggicci/httpin package)
Developer Time	😫 Expensive (too much parsing stuff code)	🚀 Faster (define the struct for receiving input data and leave the parsing job to httpin)
Code Repetition Rate	😞 High	Lower
Code Readability	😟 Poor	Highly readable
Maintainability	😡 Poor	😍 Highly maintainable
