Config driven for Auryn Injector the OOP way
In this library it is also included a bridge for the Auryn\Injector and ProxyManager for lazily initializes a "real" instance of the proxied class.
This library is still a WIP (work in progres)
Table Of Contents
Installation
The best way to use this package is through Composer:
composer require italystrap/empress
This package adheres to the SemVer specification and will be fully backward compatible between minor versions.
Basic Usage
For more information on how to use Auryn\Injector see the Auryn README
Keep in mind that $injector->(SomeClass::class)
hides the word new
and does the instantiation for you.
Do not use Injector as a service locator or your server will blown up.
