Laravel-data

This package enables the creation of rich data objects which can be used in various ways. Using this package you only need to describe your data once:

• instead of a form request, you can use a data object
• instead of an API transformer, you can use a data object
• instead of manually writing a typescript definition, you can use... 🥁 a data object

A laravel-data specific object is just a regular PHP object that extends from Data:

use Spatie\LaravelData\Data;

class SongData extends Data
{
    public function __construct(
        public string $title,
        public string $artist,
    ) {
    }
}

By extending from Data you enable a lot of new functionality like:

• Automatically transforming data objects into resources (like the Laravel API resources)
• Transform only the requested parts of data objects with lazy properties
• Automatically creating data objects from request data and validating them
• Automatically resolve validation rules for properties within a data object
• Make it possible to construct a data object from any type you want
• Add support for automatically validating data objects when creating them
• Generate TypeScript definitions from your data objects you can use on the frontend
• Save data objects as properties of an Eloquent model
• And a lot more ...

Why would you be using this package?

• You can be sure that data is typed when it leaves your app and comes back again from the frontend which makes a lot less errors
• You don't have to write the same properties three times (in a resource, in a data transfer object and in request validation)
• You need to write a lot less of validation rules because they are obvious through PHP's type system
• You get TypeScript versions of the data objects for free

Let's dive right into it!
