Laravel Providers Services

Laravel is a free open-source PHP-based framework that helps in developing responsive web applications. It follows a Model-View-Controller (MVC) architectural model based on Symfony. It has become one of the top-rated PHP frameworks that offer optimal website performance along with a myriad of benefits. The Laravel framework is very popular with Western web application developers. We want to note that Laravel is used not only for simple websites and small online stores. Increasingly Laravel framework is used by large business projects.

The popularity of the Laravel framework among developers

If you are interested in the technical reasons why using Laravel might be a smart idea, we can summarize them easily. First, Laravel’s core is very powerful in terms of performance and you can extend the platform with a variety of add-ons.

Laravel also integrates well with other third party libraries and frameworks such as Amazon Web Services (AWS), allowing you to build highly scalable applications. For long-term tasks, you can queue them up to run asynchronously in the background, further improving performance.

Key Features:

  • Laravel is a framework that prides itself on elegant syntax
  • It is possible to extend the basic functionality of Laravel with add-ons
  • Built-in functions can be used to manage routing, user management, caching, and more
  • It is possible to integrate Laravel with third party libraries and frameworks like AWS
  • With Laravel, tasks can be performed asynchronously in the background to improve performance

What are Service Providers in Laravel?

Service providers are at the heart of the bootstrapping of all Laravel applications. Both your application and all underlying Laravel services are loaded through service providers.

But what do we mean by “bootstrapping”? In general terms, we mean registering things like bindings in the IoC container (facades, etc.), event listeners, route filters, and even the routes themselves. Service providers play a central role in customizing your application.

If you open the config / app.php file that comes with Laravel, you will see the providers array. It lists all the service provider classes loaded for your application. Of course, many of them are “deferred” providers. They are not loaded on every request, but only when needed.

Using service providers

All service providers inherit the Illuminate \ Support \ ServiceProvider class. Most service providers have register and boot methods. In the register method you only have to bind your classes to the service container. Never try to register event listeners, routes, or any other function in the register method.

Using the Artisan CLI, you can create a new provider with the: make:provider

Register Method

As mentioned, inside the register method you only have to bind your classes to the service container. Never try to register event listeners, routes, or any other function  in the register method. Otherwise, you may accidentally access a service provided by a service provider that has not yet been loaded.

Let’s take a look at a simple service provider. From any method on your service provider, you always have access to the $ app property, which provides access to the service container.

This service provider only defines the register method and uses it to define the Riak \ Connection implementation in the service container.

Booth Method 

If we need to register the view composer with our service provider, it is necessary to do it in both method.

This method is called after all other service providers have been registered. And it means that you have access to all other services that were registered by the framework.

Provider registration

All service providers are registered in config / app.php. This file contains the providers array where you can add the class names of your service providers. By default, it specifies a set of basic Laravel service providers. These providers load basic Laravel components like mail handler, queue, cache, and others.

Deferred providers

If your provider only registers bindings in the service container, you can postpone registration until one of these bindings is requested from the service container. This avoids alarming the file system with every request, which will improve the performance of your application.

Laravel compiles and maintains a list of all the services provided by defer service providers and their classes.

Laravel will load the required service provider only when the application needs one of these services in the process.

To make the service provider deferred, set the property defer to true and define a method provider. 

The provider method should return the service container bindings registered with your provider.

In conclusion

If you decide to deepen your knowledge of Laravel and use it in your work, we think this is a good idea.

Laravel is useful for developers because it has super documentation compared to other frameworks or CMSs, most of which you need to search the forums for more information.

Laravel with its advantages will be in demand among developers and business for a long time.
