Best Practices for Custom Helpers in Laravel 5

Custom Classes in Laravel 5, the Easy Way
This answer is applicable to general custom classes within Laravel. For a more Blade-specific answer.

Step 1: Create your Helpers (or other custom class) file and give it a matching namespace. Write your class and method:

<?php // Code within app\Helpers\Helper.php



namespace App\Helpers;



class Helper

{

    public static function shout(string $string)

    {

        return strtoupper($string);

    }

}

Step 2: Create an alias:

<?php // Code within config/app.php



    'aliases' => [

     ...

        'Helper' => App\Helpers\Helper::class,

     ...

Step 3: Run composer dump-autoload in the project root
Step 4: Use it in your Blade template:

<!-- Code within resources/views/template.blade.php -->



{!! Helper::shout('this is how to use autoloading correctly!!') !!}

Extra Credit: Use this class anywhere in your Laravel app:

<?php // Code within app/Http/Controllers/SomeController.php



namespace App\Http\Controllers;



use Helper;



class SomeController extends Controller

{



    public function __construct()

    {

        Helper::shout('now i\'m using my helper class in a controller!!');

    }

    ...
