Russian Doll Caching for Laravel 5.3, 5.4, 5.5 and 5.6

Efficient view caching.

Inspired by the excellent series at https://laracasts.com/series/russian-doll-caching-in-laravel .

Watch that series to understand the concepts around it and to use it properly, for example: how to invalidate the cache upwards.

Installation

In your terminal/shell run:

composer require rodrigopedra/russian-doll-caching

If you're using Laravel 5.3 or 5.4 you need to register the service provider in your config/app.php providers array:

// ... 

'providers' => [
    // ... 
    
    RodrigoPedra\RussianDollCaching\RussianDollCachingServiceProvider::class,
],

// ... 

Configuration

In your terminal/shell run:

php artisan vendor:publish --provider="RodrigoPedra\RussianDollCaching\RussianDollCachingServiceProvider"

You can configure a should_cache constraint, so you can skip caching, for example, while developing locally.

Usage

Use the @russian directive in your blade templates the same way you would use the @include directive.

You can optionally inform a custom prefix that will be prepended to the cache key.

    @russian('path.to.view', compact('user', 'articles'), 'version-prefix')

    @russian('path.to.other.view', compact('user', 'articles'))
    
    {{-- caution here, the cache key will only be the view name hash! --}}
    @russian('path.to.another.view')

You can also pass multiple prefixes as an array, that will be prepended to the cache item's key:

    @russian('path.to.other.view', compact('user'), [ 'v1', 'home' ])

If your cache mechanism supports tagging, like memcached or redis, all cache items will be cached with a russian tag.

Key calculation

The caching mechanism will try to use the first element in the data array as part of the cache key.

You should use the RussianCacheableModel trait in your models or use the RussianCacheableCollection in your custom collections. This traits add a getCacheKey method to this objects so you can

FAQ

• Why are my views not updating?

  Try running php artisan view:clear and php artisan cache:clear. Also, while developing, set the should_cache config key to false.

• Can I flush just the items cached by this package?

  If you use a caching mechanism that supports tagging (memcached or redis) all the cached items are created with a russian tag. So you can clear only these items running \Cache::tags('russian')->flush() in php artisan tinker
