Laravel Routing

 Laravel Routing

In Laravel, all requests are mapped with the help of routes. Basic routing routes the request to the associated controllers. This chapter discusses routing in Laravel.

Routing in Laravel includes the following categories:

· Basic Routing

· Route parameters

· Named Routes

· Basic Routing

All Laravel routes are defined in your route files, which are located in the routes directory. These files are automatically loaded by your application's App\Providers\RouteServiceProvider. The routes/web.php file defines routes that are for your web interface. These routes are assigned the web middleware group, which provides features like session state and CSRF protection. The routes in routes/api.php are stateless and are assigned the api middleware group.

 

For most applications, you will begin by defining routes in your routes/web.php file. The routes defined in routes/web.php may be accessed by entering the defined route's URL in your browser.

The sample route for the welcome page can be seen as shown in the screenshot given below:

The routing mechanism is shown in the image given below

Let us now understand the steps involved in the routing mechanism in detail:

1. Step 1: Initially, we should execute the root URL of the application.

2. Step 2: Now, the executed URL should match with the appropriate method in the route.php file. In the present case, it should match the method and the root (‘/’) URL. This will execute the related function.

3. Step 3: The function calls the template file resources/views/welcome.blade.php. Next, the function calls the view() function with the argument ‘welcome’ without using the blade.php.

 

This will produce the HTML output as shown in the image below

Sometimes in the web application, you may need to capture the parameters passed with the URL. For this, you should modify the code in routes.php file.

You can capture the parameters in routes.php file in two ways as discussed here:

· Required Parameters

These parameters are those which should be mandatorily captured for routing the web application. For example, it is important to capture the user’s identification number from the URL. This can be possible by defining route parameters as shown below:

· Optional Parameters

Named routes allow a convenient way of creating routes. The chaining of routes can be specified using the name method onto the route definition. The following code shows an example for creating named routes with a controller:

The user controller will call for the function showProfile with parameter as a profile. The parameters use the name method in the route definition.
