Good day!
The more I read, the more I get confused about this. What is the difference between a Facade and Aliases?
I have this Class:
/app/libraries/Project/Data.php
namespace PJ;
class Data {
// It is much like a data container, with static methods and properties for saving info
}
And the corresponding facade, so I can access by using just PJD:: .
According to some webpage around:
... Laravel Facades are proxies. They wrap around and call functions on the underlying true implementation of the code. Further, in the context of a Laravel application, these Facades are accessed by assigning them to aliases. This use of the Dependency Injection container allow you to reference something like Illuminate\Support\Facades\Filesystem by simply calling File. (http://ryantablada.com/post/proxies-service-locators-alias-facades-and-war)
But, I've also found and successfully tested that adding something like:
__app/config/app.php__
'aliases' => array(
//....,
'PJD' => 'PJ\Data',
),
I can also access my class the same way.
So, what's the difference?
Thanks
EDIT #01
I have created a class named Data in /app/libraries/Project/Data.php
namespace PJ;
class Data {
// It is much like a data container, with static methods and properties for saving info
}
I have a Facade Class for this Class Data /app/libraries/Project/DataFacade.php
use Illuminate\Support\Facades\Facade;
class PJD extends Facade {
protected static function getFacadeAccessor() {
return 'PJData';
}
}
And I have a Service Provider for them: /app/libraries/Project/DataServiceProvider.php
use Illuminate\Support\ServiceProvider;
class DataServiceProvider extends ServiceProvider {
public function register() {
$this->app->singleton('PJData', function() {
return new PJ\Data;
});
}
}
I also have added to /app/config/app.php:
'providers' => array(
// ....
'DataServiceProvider',
),
and in composer.json I've added a psr-4 line to direct PJ namespace to /app/libraries/Project
"psr-4": {
"PJ\\": "app/libraries/Project"
},
By doing all this, I can access my class from anywhere in the project just by PJD:: instead of PJ\Data::.
However, I've also noticed that just by adding to /app/config/app.php
'aliases' => array(
//....,
'PJD' => 'PJ\Data',
),
I get exactly the same result without all that facades and ServiceProviders. So, what's the point of one or another?
Thanks, and sorry for the large post.
PJD
class and its methods and properties? can you edit and give example? – itachipublic static $testvar = 'Hi';
. I added to the aliases array in app.php'TestClass' => 'PJ\Test'
. And that's all. I can access from anywhereTestClass::$testvar
. Am I missing something?` – Marco Madueño Mejía
