Laravel Validator Object-Oriented Wrapper

 The Laravel Validator object-oriented wrapper package by Krzysztof Rewak provides a map of all string rules into chained methods. The builder helps you write object-oriented style rules that translate back into their string counterparts:

1$validator = new ValidationBuilder();
2$validator->validate("email", function (Field $field): void {
3    $field->string()->required()->email(["rfc"])
4});
5 
6$validator->getRules();
7// ["email" => "string|required|email:rfc]

Here’s an example of nested validation rules:

 1$validator = new ValidationBuilder();
 2$validator->validateEach("tags", function (Field $field): void {
 3    $field->array();
 4});
 5$validator->validateInEach("id", "tags", function (Field $field): void {
 6    $field->required()->exists("tags", "id");
 7});
 8 
 9$validator->getRules();
10// ["tags.*:" => "array", "tags.*.id:" => "required|exists:tags,id"]

And finally, you can also use the builder in form requests:

 1/**
 2 * @return array
 3 */
 4public function rules(): array
 5{
 6    $this->builder->validate("email", function (Field $field): void {
 7        $field->required()->string()->email()->unique("users", "email");
 8    });
 9    $this->builder->validate("password", function (Field $field): void {
10        $field->required()->string()->min(6)->confirmed();
11    });
12 
13    return $this->builder->getRules();
14}
