Plain Go vs Gin

The aim of this benchmark is to answer the question do you need framework for your tiny microservice.

Prerequisites

Let's consider simple example where we need framework only to parse URL (someone may decide that it's sufficient reason to start use framework for tiny microservice).

// service

func MustSignUp(username string) {
	mustValidation(username)
	mustSignUpFacebook(username)
	mustSignUpTwitter(username)
	mustSignUpPinterest(username)
}

func mustValidation(username string) {

// controller

func SignUp(username string) {
	defer recover.All(func(err interface{}) {
		fmt.Printf("[pro_panic] SignUp: %s \n", err)
	})
	service.MustSignUp(username)
	fmt.Printf("[pro_panic] SignUp: %s \n", "ok")
}
