Main Steps to Generate Barcode in Laravel 9

Step 1: Create Laravel Project

Open command line interface, type the command below and press enter to start installing a new Laravel app.

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

Navigate to the newly created project’s directory.

cd laravel-barcode

Step 2: Add Database Details

We will now create a database connection, and add database credentials in the .env file. This step is required only if your application interacts with a database.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=database_name
DB_USERNAME=database_user_name
DB_PASSWORD=database_password

If you are using macOS or local MAMP server, you also need to append UNIX_SOCKET and DB_SOCKET database credentials in your .env file, as shown below.

UNIX_SOCKET=/Applications/MAMP/tmp/mysql/mysql.sock
DB_SOCKET=/Applications/MAMP/tmp/mysql/mysql.sock

Step 3: Install the Barcode Package

Next, add the command as shown below to install the Barcode library.

composer require milon/barcode

Step 4: Register Barcode Library

We will now get in the config/app.php file and add the barcode service provider to register the Barcode package in the provider’s array of your Laravel app. You may also add alias to the values, as shown below.

<?php
    return [
    'providers' => [
        ....
        ....
        ....                
        Milon\Barcode\BarcodeServiceProvider::class,
    ],
    
    'aliases' => [
        ....
        ....
        ....                
        'DNS1D' => Milon\Barcode\Facades\DNS1DFacade::class,
        'DNS2D' => Milon\Barcode\Facades\DNS2DFacade::class,
    ]

Step 5: Set Up New Controller Class

Next, you can generate a new controller; that we will use it to load the blade view file.

php artisan make:controller ProductController

Open your resources/views/ProductController.blade.php file and update it with the code shown below.

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class ProductController extends Controller
{
    public function index()
    {
      return view('product');
    }
}

Step 6: Add New Barcode Route

We will now learn how to define a new route using the get method. This will interact with the controller and provide a link to view the app in a browser. So update your routes/web.php file with the code below.

<?php
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\ProductController;
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
*/
Route::get('/generate-barcode', [ProductController::class, 'index'])->name('generate.barcode');
