Inside this article we will see the concept i.e How To Work with Route Middleware in Laravel 10 Tutorial. Article contains the classified information i.e What is Route Middleware & How to use it in Laravel 10 application.

In Laravel, Middleware is a mechanism that allows developers to filter HTTP requests coming into their application. Route Middleware, specifically, refers to a Middleware that is applied to a single route or a group of routes.

In laravel we have three types of middlewares –

Global Middleware
Group Middleware
Route Middleware

Inside this article, we will see the concept of Route Middleware in Laravel 10 application.

Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

What is Route Middleware?

Route Middleware allows developers to apply specific filtering logic to a single route or a group of related routes.

This can be particularly useful in situations where you have a set of routes that require a specific type of filtering or processing, such as authentication or role-based access control.

By the help of php artisan command, we create Middleware in laravel.

$ php artisan make:middleware <MiddlewareName>

Middlewares will be stored inside /app/Http/Middleware. To register middleware inside application, Kernel.php file will be used which is inside /app/Http. Kernel.php, it’s a class file which contains registration of middlewares.

Example – Route Middleware Implementation

Let’s take an example to understand the concept of route middleware inside laravel application.

Create a Middleware which checks country, when we open URL.
Example We will have 3 routes in which a route should be protected by middleware and other two routes will be open to access for everyone.
US, IN, AFG should be allowed inside application, they can access application routes.
UK, AUS should be restricted to use or access route.

Create a Middleware

Open project into terminal and run this artisan command.

$ php artisan make:middleware CountryCheck

It will create a file with name CountryCheck.php inside /app/Http/Middleware folder.

Open CountryCheck.php file and write this following code into it.

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;

class CountryCheck
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle(Request $request, Closure $next)
    {
        if ($request->country && !in_array($request->country, array("us", "in", "afg"))) {
            return redirect("noaccess");
        }
        return $next($request);
    }
}

If request $request->country is NOT in list of these (US, IN, AFG) then it will open no access page.

Register Middleware in Application

Open Kernel.php from /app/Http. Search for $routeMiddleware and add this.

protected $routeMiddleware = [
    //...

    'apprestrict' => \App\Http\Middleware\CountryCheck::class,
    
    //...
];

apprestrict is the name of route middleware.

Create NoAccess & Protected Routes

Open web.php from /routes folder and add these route into it.

//...

Route::view("noaccess", "noaccess");

Route::get("route-1", function(){ 
  echo "<h3>Welcome To Route 1</h3>"; 
});

// Protected by middleware
Route::get("route-2", function(){ 
  echo "<h3>Welcome To Route 2</h3>"; 
})->middleware("apprestrict");
  
Route::get("route-3", function(){ 
  echo "<h3>Welcome To Route 3</h3>"; 
});

Next, we need to create noaccess.blade.php file.

Create NoAccess Page

Create a file called noaccess.blade.php inside /resources/views folder. Open file and write this simple code into it.

<h3>Sorry! You have no access to open this page.</h3>

Application Testing

Run this command into project terminal to start development server,

php artisan serve

Normal Routes

URL – http://127.0.0.1:8000/route-1/?country=us

*** Welcome To Route 1 ***

URL – http://127.0.0.1:8000/route-3/?country=uk

*** Welcome To Route 3 ***

Protected Route

URL – http://127.0.0.1:8000/route-2/?country=us

*** Welcome To Route 2 ***

URL – http://127.0.0.1:8000/route-2/?country=uk

Output:
