Attach Time-sliced Metadata to Eloquent Models

Laravel Multiplex is a Laravel package to attach time-sliced metadata to Eloquent models. With the v1.0 release near, here are the main features:

Metadata is saved in versions, including the ability to schedule metadata for the future
Fluent syntax
East to try extending your model with versionable metadata without touching original columns
Type conversion system
Configurable

Here are a few basic examples of how this package looks working with a model:

$post = \App\Models\Post::first();
 
// Set meta fluently for any key – `likes` is no column of `Post`.
$post->likes = 24;
 
// Or use the `setMeta` method.
$post->setMeta('likes', 24);
 
// Set multiple values
$model->setMeta([
    'hide' => true,
    'color' => '#000',
    'likes' => 24,
]);
 
// You may also schedule changes, for example, change the meta in 2 years:
$post->setMetaAt('likes', 6000, '+2 years');

You can also limit which meta keys are allowed on a model with a $metaKeys property:

class Post extends Model
{
    use HasMeta;
 
    protected array $metaKeys = [
        'color',
        'hide',
    ];
 
    // You can use typecast array keys
    protected array $metaKeys = [
        'foo',
        'count' => 'integer',
        'color' => 'string',
        'hide' => 'boolean',
    ];
 
}
