Laravel Dependency Injector For Laravel4

Why? The Effort

The hardet part of developing applications which should be scalable in Laravel4 is Dependency Injection. Usually, we always have that nuisance of using Use \Config or Use \Response on our applications. The big problem would be the impact of implementing this design pattern to development efficiency., _(*1)

Assuming Laravel 4 just ported and overhauled to a new framework, or imagine you, as a developer switched from using sentry to basic auth. What do you do? Efficiency and Dependency is always the issue., _(*2)

Version 0.0001

Thanks to the other library, SocialConnect, and two big API-Centric applicaitons that I'm building, There's a big problem w/ dependencies. Now, It would be no issue., _(*3)

Installation

Composer

Facades

    <?php
        ...
            'DependencyInterface' => 'Sourcescript\LaravelDependencyInjector\Facades\DependencyFacade'
        ...

Insert that into the facades array., _(*4)

disclosure: some applications and libraries you may be doing or using would or cannot directly use the Facade due to psr issues. Therefore, they may inser the following:, _(*5)

    <?php
        use Sourcescript\LaravelDependencyInjector\Interfaces\DependencyInterface;

Rather than importing alot of libraries or extensions to your library (from Laravel's Library) you may just need to import the dpependency injector and he'll do the rest, _(*6)

Providers

    <?php
        ...
        'Sourcescript\LaravelDependencyInjector\LaravelDependencyInjectorServiceProvider'
        ...

Insert the following into the providers array, _(*7)

How to use?

Here's an example of an API-centric controller which uses a better dependency injection w/ our library, _(*8)

    <?php namespace Pupilr\System\Controllers\User;

    use Sourcescript\LaravelDependencyInjector\Interfaces\DependencyInterface;

    class UserController extends APIController
    {
        protected $dependencies;

        public function __construct(DependencyInterface $dependencies)
        {
            $this->dependencies = $dependencies;
        }

        public function getIndex()
        {
            $result = [
                'code'      => 200,
                'message'   => 'hello world'
            ];

            return $this->dependencies->response->json($result)->setCallback($this->dependencies->input->get('callback'));
        }
    }

as you can see, even tho its a bit wee long, its cleaner and easier to recode and revamp, you won't have the hassle of editing all one by one., _(*9)

Dependencies Available

    <?php
        $dependencies;

        $dependencies->app();
        $dependencies->auth();
        $dependencies->cache();
        $dependencies->config();
        $dependencies->db();
        $dependencies->event();
        $dependencies->file();
        $dependencies->form();
        $dependencies->hash();
        $dependencies->html();
        $dependencies->input();
        $dependencies->redirect();
        $dependencies->response();
        $dependencies->request();
        $dependencies->session();
        $dependencies->url();
        $dependencies->validator();
        $dependencies->view();

Issue w/ Overahead

This application / library will not give much of an overhead to the current cache or memory needed by hte application since every requirement is lazy loaded by app. (see code), _(*10)

Credits go to Kier & Jeff (both are which my friends) on pointing out an err, and helping me generate a better plugin, _(*11)

Also, to SourceScript Innovations, this will and always be made w/ love., _(*12)
