Introduction

Validated DTO provides Data Transfer Objects with validation for Laravel applications. It lets you define typed objects that validate incoming data using the same validation rules you already use for requests.

DTOs are useful when data needs to move between layers of an application without coupling validation to a single transport, such as an HTTP request.

Why use this package

Request validation works well at the edge of a Laravel application, but the same operation may also run from a queued job, console command, model action, or service class. Keeping validation in the DTO lets those entry points share one validated data contract.

With this package, you define validation once and reuse it wherever the application needs that data shape.
