What is Runtype for Laravel?

Runtype for Laravel is a package that allows you to generate Typescript interfaces from your Laravel Models & Resources.

This resource:

namespace App\Http\Resources;

use Illuminate\Http\Resources\Json\JsonResource;

/** @mixin \App\Models\Product */
class ProductResource extends JsonResource
{
    public $showHiddenData = false;

    public function toArray($request)
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
            'hidden' => $this->when($this->showHiddenData, false),
        ];
    }
}

will generate this Typescript type:

declare namespace App.Http.Resources {
    export type ProductResourceType = {
        id: number;
        name: string;
        hidden?: boolean;
    }
}
