How to generate Barcode in Laravel 8

What is Barcode?

A barcode or bar code is a method of representing data in a visual, machine-readable form. A barcode is a square or rectangular image consisting of a series of parallel black lines and white spaces of varying widths that can be read by a optical barcode scanner.

Some realtime examples of barcode usage:

Barcodes are applied to products for quick identification.
Barcodes are used in retail stores as part of the purchase process.
Barcodes are used in warehouses to track inventory.
Barcodes are used on invoices to assist in accounting.

Now, lets go through step by step and see how we can generate Barcode in Laravel 8.

Step 1: Create fresh laravel 8 application

Open terminal and install fresh laravel application using below command:

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

Next, lets get inside the barcodeapp using below command:

cd barcodeapp

Step 2: Install Barcode laravel package

Next, we need to install milon/barcode package for barcode generation. Type below command in terminal:

composer require milon/barcode "^8.0"

Next, open config/app.php file and add service provider and aliase.

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

    'aliases' => [
        ....
        'DNS1D' => Milon\Barcode\Facades\DNS1DFacade::class,
        'DNS2D' => Milon\Barcode\Facades\DNS2DFacade::class,
    ]
];

Step 3: Create route

Next, we will create a route to test our example code. Open routes/web.php file and add below route in it:

<?php
use Illuminate\Support\Facades\Route;
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
Route::get('/barcode', 'BarCodeController@'index');

Step 4: Create controller

Next, create BarCodeController.php file and put below code in it:

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;

class BarCodeController extends Controller
{
    public function index()
    {
          return view('barcode');
    }
}

Step 5: Create balde file

Next, create barcode.blade.php file and put below code in it:

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>Generate Barcode in Laravel 8</title>
    <meta name="csrf-token" content="{{ csrf_token() }}">
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-1BmE4kWBq78iYhFldvKuhfTAU6auU8tT94WrHftjDbrCEXSU1oBoqyl2QvZ6jIW3" crossorigin="anonymous">
</head>
<body>
    <div class="container mt-3">
        <div class="row">
            <div class="col-12 col-sm-6 col-md-4 mb-3">
                <div class="mb-3">{!! DNS1D::getBarcodeHTML('1234567890', 'PHARMA') !!}</div>
                <div class="mb-3">{!! DNS1D::getBarcodeHTML('1234567890', 'CODABAR') !!}</div>
                <div class="mb-3">{!! DNS1D::getBarcodeHTML('1234567890', 'UPCA') !!}</div>
            </div>
        </div>
    </div>
</body>
</html>

Step 6: Start the development server using below command:

php artisan serve

Next, open below url in browser and see the result:

http://127.0.0.1:8000/barcode
