Service Providers

• Service providers are the central place of all Laravel application bootstrapping.
• Your own application, as well as all of Laravel's core services, are bootstrapped via service providers.

What is bootstrapping?
It means registering things, including 

• Service container bindings
• Event listeners
• Middleware
• Routes

Check out all providers at config/app.php. There are a lot of providers present in app.php

• Laravel Framework service providers 
• Packages service providers 
• Application service providers 

'providers' => [

        /*
         * Laravel Framework Service Providers...
         */
        Illuminate\Auth\AuthServiceProvider::class,
        Illuminate\Broadcasting\BroadcastServiceProvider::class,
        Illuminate\Bus\BusServiceProvider::class,
        Illuminate\Cache\CacheServiceProvider::class,
        Illuminate\Foundation\Providers\ConsoleSupportServiceProvider::class,
        Illuminate\Cookie\CookieServiceProvider::class,
        Illuminate\Database\DatabaseServiceProvider\

        /*
         * Package Service Providers...
         */

        /*
         * Application Service Providers...
         */
        App\Providers\AppServiceProvider::class,
        App\Providers\AuthServiceProvider::class,
        // App\Providers\BroadcastServiceProvider::class,
        App\Providers\EventServiceProvider::class,
        App\Providers\RouteServiceProvider::class,
        Laravel\Socialite\SocialiteServiceProvider::class,
    ],

Many of them are "deferred" providers, meaning they will not be loaded on every request, but only when the services they provide are actually needed.

Every service on Laravel register inside service container via the service provider 

Every service container class has two methods 
1) register 
2) boot 

Register Method

• Register method is only used to bind things to the service container. 

Boot Method

• It will be available only when the application is ready/booted. 
• So registering events, listeners, routes etc. is done on the boot method.

 

How to bind our declaration?

a) Use an inbuild service provider 

At App\Providers\AppServiceProvider.php 

We need to add a register or boot method

 

class AppServiceProvider extends ServiceProvider

{
    public function register()

    {
        app()->bind('Puneet',function(){
            return Str::random();
        });

    }
    public function boot()
    {
        //
    }

}

b) Creating your own service provider 

step 1: You can create your service provider at App\Providers\

TestServiceProvide.php

or  

php artisan make: provide TestServiceProvide

Step 3: Decelare this service provider at config/app.php

App\Providers\TestServiceProvide::class,

step 2

Then add binding at register or boot method

 

Singleton:

Decalare singleton instead of bind

 app()->singleton('Puneet',function(){
  return Str::random();
});
