Laravel Installation

We will create laravel project using composer. So, please make sure your system should have composer installed. If not, may be this article will help you to Install composer in system.

Here is the command to create a laravel project-

composer create-project --prefer-dist laravel/laravel blog

To start the development server of Laravel –

php artisan serve


Assuming laravel already installed inside your system.

Register Custom Directive

Open AppServiceProvider.php from /app/Providers folder.

To create custom blade directives we will use Blade facade.

Step #1: Import Facade

Add this to header

use Illuminate\Support\Facades\Blade;

Step #2: Register Directive

Create custom directive inside boot() method.

Blade::directive('directiveName', callbackFunction);

Here, we have the complete code for AppServiceProvider.php


namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Blade;

class AppServiceProvider extends ServiceProvider
     * Register any application services.
     * @return void
    public function register()

     * Bootstrap any application services.
     * @return void
    public function boot()
        // Directive to find cube area
        // Formula Surface area = 6 * side * side
        Blade::directive('cubearea', function ($side) {
            return "<?php echo 6*$side*$side; ?>";

        // Directive to find cube volume
        // Formula V = side * side * side
        Blade::directive('cubevolume', function ($side) {
            return "<?php echo $side*$side*$side; ?>";


We have created two custom blade directives as @cubearea and @cubevolume

@cubearea calculates surface area of cube whereas @cubevolume calculates volume of a cube.
