Install Barcode Package

In this section, we will tell you what command to use to install the Barcode package, type and execute the command to begin installing the barcode library.

composer require milon/barcode

Register Barcode Library

After completing the package installation process, get into the config/app.php and add the barcode service provider to the providers’ array. Additionally, add the values into the alias as well.

<?php
    return [
    'providers' => [
        ....
        ....
        ....                
        Milon\Barcode\BarcodeServiceProvider::class,
    ],
    
    'aliases' => [

Route::get('/generate-barcode', [ProductController::class, 'index'])->name('generate.barcode');
