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`:
```php
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
