It’s necessary to know the internal workings of any application you might be given to work with, an entire understanding of that application will allow you to make use of all the ability that comes with the application. In this case, understanding how laravel works below the hood will help us make the most of all of it is awesome “power”. When we wish to learn extra about the laravel framework, the request lifecycle is the most effective place to begin. It defines what’s taking place between an http request to our utility until the response. Looking on the request lifecycle in depth will help us understand laravel’s structure better.
Everything in a laravel application begins from the index.php file found within the public directory. The index.php file is so important as a result of any call or request into our application will initially route to it. In the index.php file, the applying will get saved as an utility occasion, which is also referred to as a service container. Behind the scenes, various things are taking place within the service container. One of which is the registration and storage of core classes that can be used later.
The HTTP Kernel is located within the app/Http/Kernel.php , all the application’s middlewares are registered on this file such because the middleware groups and the route middlewares. The http kernel is the following place the incoming request is sent to. It receives a request and returns a response. All of that is completed by the deal with method out there to the Kernel class. Once the handle method recognises a HTTP request, it returns a HTTP response. The Kernel class extends the Illuminate\Foundation\Http\Kernel class which accommodates a bootstrap method. This method checks if our application has been bootstrapped already. If not, the bootstrap method runs on a bunch of classes to bootstrap the application. It loads the configuration file, loads additionally the environment variables, handles exceptions, registers facades and likewise registers the application’s service providers. The application’s default service providers are stored within the app/Providers directory.
