Service, service Container, service Providers in laravel

1. Service is a class to perform some feature, or logic in the Laravel app

2. Service Container is a place containing registered services in the Larravel app

3. The Service Provider serves as a bridge to register services to the service container

- To register a service for Service Container you can register it in the service provider, you can use the bind() or singleton() method

$this->app->bind('App\Services\PaymentGateway', function ($app) {

    return new \App\Services\PaymentGateway(config('services.payment.api_key'));

});

$this->app->singleton('App\Services\PaymentGateway', function ($app) {

    return new \App\Services\PaymentGateway(config('services.payment.api_key'));

});

- To register a service provider to Laravel, there are 2 ways:

(1) Config Service provider in config/app.php

'providers' => [

    // Other Service Providers

    App\Providers\MyCustomServiceProvider::class,

],

(2) Config service provider in composer.json

"extra": {

    "laravel": {

        "providers": [

            "Vendor\\Package\\ServiceProvider"

        ],

        "aliases": {

            "SomeAlias": "Vendor\\Package\\Facade"

        }

    }

}

Thank you
