It is great that I find this article https://laravel-news.com/service-providers that talks about Service Providers in Laravel and explains the importance of this feature and how to use it in our projects. It is better to delve into it, but I will talk about the main points in the article.
Let’s start with the default service providers included in Laravel, they are all in the app/Providers folder
- AppServiceProvider
- AuthServiceProvider
- BroadcastServiceProvider
- EventServiceProvider
- RouteServiceProvider
Inside boot() of that method, you can write any code related to one of those sections: auth, events, routes, etc. In other words, Service Providers are just classes to register some global functionality
class
RouteServiceProvider
extends
ServiceProvider
{
public
const
HOME
=
'/dashboard'
;
public
function
boot
()
{
$this
->
configureRateLimiting
();
$this
->
routes
(
function
()
{
Route
::
prefix
(
'api'
)
->
middleware
(
'api'
)
->
group
(
base_path
(
'routes/api.php'
));
Route
::
middleware
(
'web'
)
->
group
(
base_path
(
'routes/web.php'
));
});
}
protected
function
configureRateLimiting
()
{
RateLimiter
::
for
(
'api'
,
function
(
Request
$request
)
{
return
Limit
::
perMinute
(
60
)
->
by
(
$request
->
user
()
?->
id
?:
$request
->
ip
());
});
}
}

One popular example of adding code to the AppServiceProvider is about disabling the lazy loading in Eloquent. To do that, you just need to add two lines into the boot() method
// app/Providers/AppServiceProvider.php
use
Illuminate\Database\Eloquent\Model
;
public
function
boot
()
{
Model
::
preventLazyLoading
(
!
$this
->
app
->
isProduction
());
}
Enter fullscreen mode
Exit fullscreen mode
Which providers are loaded? It’s defined in the config/app.php array
return
[
// ... other configuration values
'providers'
=>
[
/*
* Laravel Framework Service Providers...
*/
Illuminate\Auth\AuthServiceProvider
::
class
,
Illuminate\Broadcasting\BroadcastServiceProvider
::
class
,
// ... other framework providers from /vendor
Illuminate\Validation\ValidationServiceProvider
::
class
,
Illuminate\View\ViewServiceProvider
::
class
,
/*
* PUBLIC Service Providers - the ones we mentioned above
*/
App\Providers\AppServiceProvider
::
class
,
App\Providers\AuthServiceProvider
::
class
,
// App\Providers\BroadcastServiceProvider::class,
App\Providers\EventServiceProvider
::
class
,
App\Providers\RouteServiceProvider
::
class
,
],
];

- Create Your Custom Service Provider
You can generate it with this command
php
artisan
make
:
provider
ViewServiceProvider
Enter fullscreen mode
Exit fullscreen mode
inside of boot() add Blade directive code
namespace
App\Providers
;
use
Illuminate\Support\ServiceProvider
;
use
Illuminate\Support\Facades\Blade
;
class
ViewServiceProvider
extends
ServiceProvider
{
/**
* Register services.
*
* @return void
*/
public
function
register
()
{
//
}
/**
* Bootstrap services.
*
* @return void
*/
public
function
boot
()
{
Blade
::
directive
(
'datetime'
,
function
(
$expression
)
{
return
"<?php echo (
$expression
)->format('m/d/Y H:i'); ?>"
;
});
}
}
Enter fullscreen mode
Exit fullscreen mode
To be executed, this new provider should be added to the array of providers in config/app.php, as mentioned above
return
[
// ... other configuration values
'providers'
=>
[
App\Providers\AppServiceProvider
::
class
,
App\Providers\AuthServiceProvider
::
class
,
// App\Providers\BroadcastServiceProvider::class,
App\Providers\EventServiceProvider
::
class
,
App\Providers\RouteServiceProvider
::
class
,
// Add your provider here
App\Providers\ViewServiceProvider
::
class
,
],
];

He talked about the main points and I hope you will visit the source to dig deeper and learn some examples from Open-Source Projects and I hope you enjoyed.
