ManagedCache
============

[](#managedcache)

> "There are only two hard problems in Computer Science: cache invalidation and naming things."

\-- Phil Karlton

ManagedCache solves one of these.

When caching data (say, a fully hydrated `User` with all of its related data -- roles, subscriptions, preferences, etc.), you would normally have to invalidate that cache in *every part of the code where one of those roles, subscriptions or preferences is modified*.

ManagedCache lets you define the invalidation criteria in the same statement that caches the data.

Requirements
------------

[](#requirements)

### Cache driver requirements

[](#cache-driver-requirements)

ManagedCache uses [tags](https://laravel.com/docs/master/cache#cache-tags) to perform its automatic event-based invalidation. This means that your cache driver should support tags (the `file` and `database` drivers do not).

ManagedCache currently only supports the Memcached cache driver. Support for other cache drivers such as Redis is planned.

### Model requirements

[](#model-requirements)

Models that are used in [invalidation conditions](#automatic-invalidation) should have an integer primary key.

Install
-------

[](#install)

Via Composer

```
$ composer require codefocus/managedcache
```

Quick start
-----------

[](#quick-start)

### Provider

[](#provider)

Add `ManagedCacheProvider` to the "providers" array in `config/app.php`

```
Codefocus\ManagedCache\Providers\ManagedCacheProvider::class
```

### Facade

[](#facade)

ManagedCache also provides a Facade.

To use it, add `Codefocus\ManagedCache\Facades\ManagedCache` to your `use` statements.

Usage
-----

[](#usage)

### Compatibility

[](#compatibility)

ManagedCache implements the `Illuminate\Contracts\Cache\Store` interface, and can be used as a drop-in replacement for the `Cache` Facade.

```
//  Retrieve a user.
$user = User::with(['roles', 'subscriptions', 'preferences'])->find($userId);

//  Store data as you normally would.
$cacheKey = 'users(' . $userId . ')';
ManagedCache::put($cacheKey, $user, 120);

...

//  Retrieve data as you normally would.
$user = ManagedCache::get($cacheKey);
```

### Automatic invalidation

[](#automatic-invalidation)

To automatically invalidate this data, call the `setForgetConditions()` function at the start of the function chain, passing in an array of invalidation conditions.

These invalidation conditions (`Codefocus\ManagedCache\Condition` objects) are named after the Eloquent events that trigger them, and can be created with intuitive helper functions:

```
//  Store data, and invalidate this cache when one of these conditions is met:
//  - This User is deleted
//  - This User is updated
//  - A Role is attached to this User
//  - A Role is detached from this User
//  - A Role attached to this User is updated
//  - A Subscription is attached to this User
//  - A Subscription is detached from this User
//  - A Subscription attached to this User is updated
//  - A Preference is attached to this User
//  - A Preference is detached from this User
//  - A Preference attached to this User is updated
ManagedCache
    ::setForgetConditions(function ($conditionBuilder) use ($user) {
        return $conditionBuilder
            ->modelDeleted($user)
            ->modelUpdated($user)
            ->relatedModelAttached($user, Role::class)
            ->relatedModelDetached($user, Role::class)
            ->relatedModelUpdated($user, Role::class)
            ->relatedModelAttached($user, Subscription::class)
            ->relatedModelDetached($user, Subscription::class)
            ->relatedModelUpdated($user, Subscription::class)
            ->relatedModelAttached($user, Preference::class)
            ->relatedModelDetached($user, Preference::class)
            ->relatedModelUpdated($user, Preference::class);
    })
    ->put($cacheKey, $user, 120);
```

As you can see, more complex data with many invalidation conditions could get cumbersome to define. To invalidate a cache key on *any* of the Eloquent events (`created`, `updated`, `saved`, `deleted` or `restored`) for the specified Model class or instance, use `anyModelEvent()` and `anyRelatedModelEvent()`:

```
//  Store data, and invalidate this cache when one of these conditions is met:
//  - This User is created, updated, saved, deleted or restored
//  - A Role attached to this User is created, updated, saved, deleted or restored
//  - A Subscription attached to this User is created, updated, saved, deleted or restored
//  - A Preference attached to this User is created, updated, saved, deleted or restored
ManagedCache
    ::setForgetConditions(function ($conditionBuilder) use ($user) {
        return $conditionBuilder
            ->anyModelEvent($user)
            ->anyRelatedModelEvent($user, Role::class)
            ->anyRelatedModelEvent($user, Subscription::class)
            ->anyRelatedModelEvent($user, Preference::class);
    })
    ->put($cacheKey, $user, 120);
```
