Is laravel-data Laravel dependent?

[rendesadam]

Is it possible to use this package in a non-Laravel project, for example in Slim framework?
I like the functionality, but I'm not sure I can use it.

(Of course, I see the name of the package, but I don't see any huge dependency in composer.json)

It's possible but not very easy. It doesn't have many dependencies but it implicitly depends on a global app function which returns a laravel container (package illuminate/container) and a global config function that returns a config object (package illuminate/config) or classes that have similar functions (since it doesn't check for an interface).

I was able to make a small proof of concept only using laravel-data and the container package:

The global helpers (copied from a laravel project):

<?php
use Illuminate\Container\Container;

function app($abstract = null, array $parameters = [])
{
    if (is_null($abstract)) {
        return Container::getInstance();
    }
    return Container::getInstance()->make($abstract, $parameters);
}

function config($key = null, $default = null)
{
    if (is_null($key)) {
        return app('config');
    }
    if (is_array($key)) {
        return app('config')->set($key);
    }
    return app('config')->get($key, $default);
}

For the config I made a small class but you'll need the full package for configuring laravel-data since it deals with nested arrays:

class Config
{
    public function __construct(public array $config = []) {}

    public function get(string $key, mixed $default = null): mixed
    {
        return $this->config[$key] ?? $default;
    }

    public function set(array|string $key, mixed $value = null)
    {
        if (is_array($key)) {
            foreach ($key as $_key => $_value) {
                $this->config[$_key] = $_value;
            }
        } else {
            $this->config[$key] = $value;
        }
    }
}

The Test data class:

use Spatie\LaravelData\Data;

class Foo extends Data
{
    public function __construct(
        public string $title = 't',
        public string $slug = 's',
    ) {}
}

The container configuration:

use Spatie\LaravelData\Support\DataConfig;

app()->singleton('config', function () {
    return new Config([
        'data.normalizers' => [
            \Spatie\LaravelData\Normalizers\ModelNormalizer::class,
            \Spatie\LaravelData\Normalizers\ArrayableNormalizer::class,
            \Spatie\LaravelData\Normalizers\ObjectNormalizer::class,
            \Spatie\LaravelData\Normalizers\ArrayNormalizer::class,
            \Spatie\LaravelData\Normalizers\JsonNormalizer::class,
        ]
    ]);
});
app()->singleton(DataConfig::class, fn () => new DataConfig([]));

And finally the test itself:

<?php
$foo = Foo::from(['title' => '123', 'slug' => '456']);
var_dump($foo->title); // "123"
var_dump($foo->slug); // "456"

I didn't try anything more complex so you'll probably need to tinker with it to get it to work well.

Thanks for your comment, very useful!

Yeah something for v6 maybe haha, it will be a lot of work to do it correct but at a certain point in time we'll maybe release spatie/data 😄

Good comment BTW 👍
