Hello all . Now on this blog is to I will help you to know about Laravel's Request Life Cycle. You can know from here how laravel framework processes the given request in different stages and provide the response to the user. So we will know these steps by steps process for better understanding about laravel request lifecycle. For More Articles you follow here.
Auto Loader
At first we know about entry point. The entry point for all requests in a Laravel application is public/index.php file. So all requests are directed to this file by our web server as we use Apache or Nginx configuration. The index.php file doesn't contain so much code. It is just starting point for loaded the rest parts of the laravel framework application.
It also loaded the auto loader files which are generated by composer. Then it also retrieves an instance of the laravel application from bootstrap/app.php script file. Laravel itself also creates an instance of the application, is the initial or first step. For Best Vue js articles you can follow here.
Kernel
Now we are look for Next step. Application next step is occurs on the Kernel part of the laravel framework. The all incoming request will be send to the HTTP kernel or the console kernel, so it’s depends on the type of request that is entering on the laravel application. So these two kernels serve as a central location so that all requests are flows through.
HTTP kernel, which is locate in app/Http/Kernel.php. It is just receives a Request and return a Response. Also all bootstrappers are defined on the location of Kernel class, which is also configures all error handling, configure logging, also detect environments and other tasks to be done before the all request handled.
In HTTP Kernel will also define the lists of middleware so that all are pass through before handled by applications.
Service Providers
Now next step of the kernel will be loaded all service providers. It is a main part of the bootstrapping action. So Providers that are also needed for the application are placed in config/app.php configuration file in laravel application.
While the register method is call, all the providers will be registered. So once all providers are registered, then boot method will be called.
Dispatch Request
Once the application has been bootstrapped and all service providers are registered and booted, and that time the request will be handed over to the router for dispatching. So the router will dispatch on the request to the route or the controller, also as well as run any route specific middleware.
Router
So now request will be dispatched by the Router. And it will be end up with the views as shown below: So the router will direct the HTTP Request to a Controller or return to a view file or return to responses directly by omitting by the controller file. These routes will be placed in file app/routes.php. All Controllers on app/controllers/ performs specific actions and sends data to a View file.
View location app/views/ formats the data appropriately, providing all the HTTP Response. That’s all .The above steps are details explain of the
diagrammatical view above.
