Laravel Cache
Installation
To get the latest version of Laravel Cache, simply require the project using Composer:
$ composer require dragon-code/laravel-cacheOr manually update require block of composer.json and run composer update.
{
"require": {
"dragon-code/laravel-cache": "^3.0"
}
}Using
Keys And Tags
In addition to passing an explicit value, you can also pass objects and arrays to the keys and tags methods.
For example:
use DragonCode\Cache\Services\Cache;
use Tests\Fixtures\Dto\DtoObject;
use Tests\Fixtures\Simple\CustomObject;
$arr1 = ['foo', 'bar'];
$arr2 = new ArrayObject(['foo', 'bar']);
$arr3 = DtoObject::make(['foo' => 'Foo', 'bar'=> 'Bar']);
$arr4 = new CustomObject();
Cache::make()->key($arr1)->tags($arr1);
Cache::make()->key($arr2)->tags($arr3);
Cache::make()->key($arr2)->tags($arr3);
Cache::make()->key($arr4)->tags($arr4);
Cache::make()->key([$arr1, $arr2, $arr3, $arr4, 'foo', 'bar'])->tags([$arr1, $arr2, $arr3, $arr4, 'foo', 'bar']);
Cache::make()->key([$arr1, $arr2, $arr3, $arr4, 'foo', 'bar'])->tags([$arr1, $arr2, $arr3, $arr4, 'foo', 'bar']);
Cache::make()->key([$arr1, $arr2, $arr3, $arr4, 'foo', 'bar'])->tags([$arr1, $arr2, $arr3, $arr4, 'foo', 'bar']);Unpacking and processing of objects occurs as follows:
use DragonCode\Cache\Services\Cache;
use Tests\Fixtures\Dto\DtoObject;
use Tests\Fixtures\Simple\CustomObject;
['Foo', 'Bar'];
// as key: ['Foo', 'Bar']
// as tag: ['foo', 'bar']
new ArrayObject(['Foo', 'Bar']);
// as key: ['Foo', 'Bar']
// as tag: ['foo', 'bar']
DtoObject::make(['foo' => 'Foo', 'bar'=> 'Bar']);
// as key: ['Foo', 'Bar']
// as tag: ['foo', 'bar']
new CustomObject();
// as key: ['Foo']
// as tag: ['foo']Keys Handling
Since the main problem of working with the cache's key compilation, this package solves it.
By passing values to the keys method, we get a ready-made key at the output.
For example:
use DragonCode\Cache\Services\Cache;
$cache = Cache::make()->key('foo', 'bar', [null, 'baz', 'baq']);
// Key is `acbd18db4cc2f85cedef654fccc4a4d8:37b51d194a7513e45b56f6524f2d51f2:73feffa4b7f6bb68e44cf984c85f6e88:b47951d522316fdd8811b23fc9c2f583`This means that when writing to the cache, the tree view will be used.
For example:
use DragonCode\Cache\Services\Cache;
Cache::make()->key('foo', 'foo')->put('foo');
Cache::make()->key('foo', 'bar')->put('bar');
Cache::make()->key('baz')->put('baz');
// acbd18db4cc2f85cedef654fccc4a4d8:
// acbd18db4cc2f85cedef654fccc4a4d8: foo
// 37b51d194a7513e45b56f6524f2d51f2: bar
// 73feffa4b7f6bb68e44cf984c85f6e88: bazWith Authentication
In some cases, it is necessary to bind the cache to certain users. To do this, we have added the withAuth helper.
use DragonCode\Cache\Services\Cache;
use Illuminate\Support\Facades\Auth;
// before
return Cache::make()->key(get_class(Auth::user()), Auth::id(), 'foo', 'bar');
// after
return Cache::make()->withAuth()->key('foo', 'bar');When processing requests with a call to the withAuth method, the binding will be carried out not only by identifier, but also by reference to the model class, since a project can have several models with the possibility of authorization.
For example, App\Models\Employee, App\Models\User.
When Enabled
Basic
use DragonCode\Cache\Services\Cache;
$cache = Cache::make()->key('foo', 'bar', ['baz', 'baq']);
$cache->put(static fn() => 'Some value');
// or
$cache->put('Some value');
// Contains cached `Some value`
$cache->remember(static fn() => 'Some value');
// or
$cache->remember('Some value');
// Contains cached `Some value`
$cache->get();
// Returns cached `Some value`
$cache->has();
// Returns `true`
$cache->doesntHave();
// Returns `false`
$cache->forget();
// Will remove the key from the cache.use DragonCode\Cache\Services\Cache;
use App\Models\User;
$user = User::first();
$cache = Cache::make()->key('foo');
$cache->put(static fn() => $user);
// or
$cache->put($user);
// Contains cached `$user`
$cache->remember(static fn() => $user);
// or
$cache->remember($user);
// Contains cached `$user`
$cache->get();
// Returns User model
$cache->has();
// Returns `true`
$cache->doesntHave();
// Returns `false`
$cache->forget();
// Will remove the key from the cache.Custom TTL
By default, the cache will be written for 1 day.
The cache will be written for the specified number of minutes, seconds or the DateTimeInterface instance.
It does not matter in which direction the time shift will be. During processing, the value is converted to the abs().
As Minutes
use Carbon\Carbon;
use DateTime;
use DragonCode\Cache\Services\Cache;
use DragonCode\Cache\Support\Ttl;
$cache = Cache::make()->ttl(10);
$cache = Cache::make()->ttl('10');
$cache = Cache::make()->ttl(fn () => 10);
$cache = Cache::make()->ttl(Carbon::now()->addDay());
$cache = Cache::make()->ttl(new DateTime('tomorrow'));
$cache = Cache::make()->ttl(Ttl::DAY);
$cache = Cache::make()->ttl(Ttl::WEEK);
$cache = Cache::make()->ttl(Ttl::MONTH);As Seconds
use Carbon\Carbon;
use DateTime;
use DragonCode\Cache\Services\Cache;
$cache = Cache::make()->ttl(10, false);
$cache = Cache::make()->ttl('10', false);
$cache = Cache::make()->ttl(fn () => 10, false);
$cache = Cache::make()->ttl(Carbon::now()->addDay(), false);
$cache = Cache::make()->ttl(new DateTime('tomorrow'), false);By Objects And Custom Strings
You can also store all TTL values in one place - in the config/cache.php file.
To do this, add a ttl block to the file and define a TTL for the objects.
After that you can use the following construction:
use DragonCode\Cache\Services\Cache;
use Tests\Fixtures\Simple\CustomObject;
$cache = Cache::make()->ttl(CustomObject::class);
$cache = Cache::make()->ttl(new CustomObject());
$cache = Cache::make()->ttl('custom_key');
// You can also specify that these values are in seconds, not minutes:
$cache = Cache::make()->ttl(CustomObject::class, false);
$cache = Cache::make()->ttl(new CustomObject(), false);
$cache = Cache::make()->ttl('custom_key', false);If the value is not found, the default value will be taken, which you can also override in the configuration file.
With Contract
Starting with version 2.9.0, we added the ability to dynamically specify TTLs in objects. To do this, you
need to implement the DragonCode\Contracts\Cache\Ttl contract into your object and add a method that returns one of the following types of variables: DateTimeInterface
, Carbon\Carbon, string
or integer.
This method will allow you to dynamically specify the TTL depending on the code being executed.
For example:
use DragonCode\Cache\Services\Cache;
use DragonCode\Contracts\Cache\Ttl;
class Foo implements Ttl
{
protected $value;
public function __construct(string $value)
{
$this->value = $value;
}
public function cacheTtl(): int
{
return $this->value === 'foo' ? 123 : 456;
}
}
$cache = Cache::make()->ttl(new Foo('foo'));
// TTL is 7380 seconds
$cache = Cache::make()->ttl(new Foo('bar'));
// TTL is 27360 seconds
$cache = Cache::make()->ttl(new Foo('foo'), false);
// TTL is 123 seconds
$cache = Cache::make()->ttl(new Foo('bar'), false);
// TTL is 456 secondsTagged
For repositories that support tagging, the keys will be saved separated by tags.
use DragonCode\Cache\Services\Cache;
$cache = Cache::make()
->tags('actor', 'author')
->key('foo', 'bar', ['baz', 'baq']);
$cache->put(static fn() => 'Some value');
// or
$cache->put('Some value');
// Contains cached `Some value`
$cache->get();
// Returns cached `Some value`
$cache->has();
// Returns `true`
$cache->doesntHave();
// Returns `false`
$cache->forget();
// Will remove the key from the cache.To retrieve a tagged cache item, pass the same ordered list of tags to the tags method and then call the get method with the key you wish to retrieve:
use DragonCode\Cache\Services\Cache;
$cache = Cache::make()->key('foo', 'bar');
$cache->tags('actor', 'author')->put(static fn() => 'Some value');
// or
$cache->tags('actor', 'author')->put('Some value');
// Contains cached `Some value`
$cache->tags('actor', 'author')->get();
// Returns cached `Some value`
$cache->tags('actor')->get();
// Returns `null`
$cache->tags('author')->get();
// Returns `null`See the official Laravel documentation.
When Disabled
Passing when = false will not write to the cache.
use DragonCode\Cache\Services\Cache;
$cache = Cache::make()
->when(false)
->key('foo', 'bar');
$value = $cache->put(static fn() => 'Some value');
// or
$value = $cache->put('Some value');
// Returns `Some value`
$cache->get();
// Returns `null`
$cache->has();
// Returns `false`
$cache->doesntHave();
// Returns `true`License
