Get into the command prompt, type the given command, and begin installing the simplesoftwareio/simple-qrcode package; it profoundly helps create various kinds of QR codes in the laravel app.

composer require simplesoftwareio/simple-qrcode

Register QR Code Service

You have to register the QR code services into the config/app.php file, so open the file and update the providers and alias array with the given below services.

<?php

    return [

    'providers' => [
        ....                
        SimpleSoftwareIO\QrCode\QrCodeServiceProvider::class,
    ],
    
    'aliases' => [
        ....                
        'QrCode' => SimpleSoftwareIO\QrCode\Facades\QrCode::class,
    ]

Create Controller

In laravel, all the business logic goes into the controller file, and we need a controller to create one by using the given command.

php artisan make:controller QrCodeController

Next, Open QrCodeController.php and add the following code into the file:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class QrCodeController extends Controller
{
    public function index()
    {
      return view('qrcode');
    }
}

Add Route

Now, open the web.php file and add the following routes into it, which are located inside the routes directory:

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\QrCodeController;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
*/

Route::get('/qrcode', [QrCodeController::class, 'index']);

Generate QR Codes in Blade View

We will show you how to use the view file and generate simple and colored QR Codes in laravel.

Now, you are ready to set up a blade view file, hence creating the blade view file within the views folder, after that add the provided code in the resources/views/qrcode.blade.php file.
