Laravel Optimus

Introduction

Laravel wrapper for the Optimus Library by Jens Segers with multiple connections support. Optimus is a small open-source library that generates short, unique, non-sequential ids from numbers. With this library, you can transform your internal id's to obfuscated integers based on Knuth's integer hash. It is similar to Hashids, but will generate integers instead of random strings. It is also super fast.

Features

• Configurable multiple Optimus connections support.
• Implicit route model binding.
• Designed to work with Laravel Eloquent models.
• Dependency Injection ready.
• Includes Facade.
• Following PHP Standard Recommendations:
  • PSR-1 (Basic Coding Standard).
  • PSR-2 (Coding Style Guide).
  • PSR-4 (Autoloading Standard).
• Covered with unit tests.

Installation

First, pull in the package through Composer.

$ composer require cybercog/laravel-optimus

Register Package Manually (optional)

If you disabled package auto-discovery you can register it manually.

Include the service provider within app/config/app.php.

'providers' => [
    Cog\Laravel\Optimus\Providers\OptimusServiceProvider::class,
],

If you want you can use the facade. Add the reference in config/app.php to your aliases array.

'aliases' => [
    'Optimus' => Cog\Laravel\Optimus\Facades\Optimus::class,
],

Configuration

Laravel Optimus requires connection configuration. To get started, you'll need to publish config file:

$ php artisan vendor:publish --provider="Cog\Laravel\Optimus\Providers\OptimusServiceProvider" --tag="config"

This will create a config/optimus.php file in your app that you can modify to set your configuration. Also, make sure you check for changes to the original config file in this package between releases.

Default Connection Name

This option default is where you may specify which of the connections below you wish to use as your default connection for all work. Of course, you may use many connections at once using the manager class. The default value for this setting is main.

Optimus Connections

This option connections is where each of the connections are setup for your application. Example configuration has been included, but you may add as many connections as you would like.

Optimus numbers generation

To get started you will need 3 keys in main connection;

• prime: Large prime number lower than 2147483647
• inverse: The inverse prime so that (PRIME * INVERSE) & MAXID == 1
• random: A large random integer lower than 2147483647

Luckily for you, there is console command that can do all of this for you, just run the following command:

$ php vendor/bin/optimus spark

Copy-paste generated integers to your connection config.

Usage

OptimusManager

This is the class of most interest. It is bound to the ioc container as optimus and can be accessed using the Facades\Optimus facade. This class implements the ManagerInterface by extending AbstractManager. The interface and abstract class are both part of Graham Campbell's Laravel Manager package, so you may want to go and checkout the docs for how to use the manager class over at that repository. Note that the connection class returned will always be an instance of Jenssegers\Optimus\Optimus.

Facades\Optimus

This facade will dynamically pass static method calls to the optimus object in the ioc container which by default is the OptimusManager class.

Providers\OptimusServiceProvider

This class contains no public methods of interest. This class should be added to the providers array in config/app.php. This class will setup ioc bindings.

Traits\OptimusEncodedRouteKey

This trait can be used in an Eloquent model to enable automatic route model binding. You can then type hint a model in a route closure or a controller and Laravel will try to find it based on the encoded ID.

Examples

Here you can see an example of just how simple this package is to use. Out of the box, the default adapter is main. After you enter your authentication details in the config file, it will just work:

Encode ID

Cog\Laravel\Optimus\Facades\Optimus::encode(20); // 1535832388

Decode ID

Cog\Laravel\Optimus\Facades\Optimus::decode(1535832388); // 20

Alter Optimus connection

The Optimus manager will behave like it is a Jenssegers\Optimus\Optimus. If you want to call specific connections, you can do that with the connection method:

use Cog\Laravel\Optimus\Facades\Optimus;

// Writing this…
Optimus::connection('main')->encode($id);

// …is identical to writing this
Optimus::encode($id);

// and is also identical to writing this.
Optimus::connection()->encode($id);

// This is because the main connection is configured to be the default.
Optimus::getDefaultConnection(); // This will return main.

// We can change the default connection.
Optimus::setDefaultConnection('alternative'); // The default is now alternative.

Dependency Injection

If you prefer to use dependency injection over facades like me, then you can inject the manager:

use Cog\Laravel\Optimus\OptimusManager;

class Foo
{
    protected $optimus;

    public function __construct(OptimusManager $optimus)
    {
        $this->optimus = $optimus;
    }
    
    public function bar($id)
    {
        return $this->optimus->encode($id)
    }
}

app()->make('Foo')->bar(20);

Implicit route model binding

To enable implicit route model binding based on the encoded ID, all you need to do is configure the prime numbers and use the Cog\Laravel\Optimus\Traits\OptimusEncodedRouteKey trait in your model.

If you don't want to use the default Optimus connection, you can specify a custom connection by adding an $optimusConnection property to you model.

use Cog\Laravel\Optimus\Traits\OptimusEncodedRouteKey;
use Illuminate\Database\Eloquent\Model;

class YourModel extends Model
{
    use OptimusEncodedRouteKey;
    
    protected $optimusConnection = 'custom'; // optional
}

Now you can type hint your model in a route closure or controller and Laravel will use the encoded ID to query the database.

Note: Implicit route model binding requires Laravel's Illuminate\Routing\Middleware\SubstituteBindings middleware, which is part of the web middleware group.

Route::get('url/to/{model}', function (YourModel $model) {
    // ...
})->middleware('web');

To generate URL's to these routes you can either get the encoded route key:

$encodedId = $model->getRouteKey();
$url = url("url/to/{$encodedId}");

Or you can use named routes and pass it the model. Laravel will do the rest.

$url = route('my.named.route', $model);
