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:

 1$post = \App\Models\Post::first();
 2 
 3// Set meta fluently for any key – `likes` is no column of `Post`.
 4$post->likes = 24;
 5 
 6// Or use the `setMeta` method.
 7$post->setMeta('likes', 24);
 8 
 9// Set multiple values
10$model->setMeta([
11    'hide' => true,
12    'color' => '#000',
13    'likes' => 24,
14]);
15 
16// You may also schedule changes, for example, change the meta in 2 years:
17$post->setMetaAt('likes', 6000, '+2 years');

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

 1class Post extends Model
 2{
 3    use HasMeta;
 4 
 5    protected array $metaKeys = [
 6        'color',
 7        'hide',
 8    ];
 9 
10    // You can use typecast array keys
11    protected array $metaKeys = [
12        'foo',
13        'count' => 'integer',
14        'color' => 'string',
15        'hide' => 'boolean',
16    ];
17 
18}
