###Lightweight struct validator I built this for personal use to validate struct. it only validates string and slice field.

adding validator:"require" to your struct property like the example below.

go get https://github.com/apisit/go-struct-validator

example.

person := struct {
	FirstName string `json:"first_name,omitempty" validator:"require"`
	LastName  string `json:"last_name,omitempty" validator:"require"`
}{}
person.FirstName = "Apisit"
validateErr := validator.Validate(person)
if validateErr != nil {
	log.Printf("validation error: %v", validateErr)
	return
}
