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',
    ];
 
}
