README

Laravel package for QR Code and Barcode generation using EduplusQR and EduplusBarcode with configurable binary paths. This approach allows you to use a single set of binaries across all your Laravel projects without bundling heavy binary files in each project.

Features

• Configurable Binary Paths: Set binary locations once, use across all projects
• Lightweight Package: No bundled binaries, reducing package size
• Fluent API: Clean, chainable method syntax
• Laravel Integration: Service provider and config publishing
• QR Code Generation: Full EduplusQR functionality
• Barcode Generation: Support for Code128, Code39, EAN-13
• Environment Configuration: Set paths via .env file

Installation

Install via Composer:

composer require eduplus/qr

Publish the configuration file:

php artisan vendor:publish --tag=eduplusqr-config

This will create config/eduplusqr.php in your Laravel project.

Binary Setup

1. Download Binaries

Download the appropriate binaries for your system from EduplusQR and EduplusBarcode packages, or place them in a shared location:

# Example: Create a shared binary directory
sudo mkdir -p /usr/local/bin/eduplus

# Copy binaries (adjust paths as needed)
sudo cp EduplusQR-linux-amd64 /usr/local/bin/eduplus/
sudo cp EduplusBarcode-linux-amd64 /usr/local/bin/eduplus/

# Make them executable
sudo chmod +x /usr/local/bin/eduplus/EduplusQR-linux-amd64
sudo chmod +x /usr/local/bin/eduplus/EduplusBarcode-linux-amd64

2. Configure Binary Paths

Option A: Via .env file (recommended):

EDUPLUS_QR_BINARY_PATH=/usr/local/bin/eduplus/EduplusQR-linux-amd64
EDUPLUS_BARCODE_BINARY_PATH=/usr/local/bin/eduplus/EduplusBarcode-linux-amd64

Option B: Via config/eduplusqr.php:

return [
    'qr_binary_path' => '/usr/local/bin/eduplus/EduplusQR-linux-amd64',
    'barcode_binary_path' => '/usr/local/bin/eduplus/EduplusBarcode-linux-amd64',
];

Platform-Specific Binary Names

• Linux x86_64: EduplusQR-linux-amd64, EduplusBarcode-linux-amd64
• Linux ARM64: EduplusQR-linux-arm64, EduplusBarcode-linux-arm64
• macOS Intel: EduplusQR-darwin-amd64, EduplusBarcode-darwin-amd64
• macOS Apple Silicon: EduplusQR-darwin-arm64, EduplusBarcode-darwin-arm64
• Windows: EduplusQR-windows-amd64.exe, EduplusBarcode-windows-amd64.exe

Usage

QR Code Generation

Basic Usage

use Eduplus\QrCode;

// Simple QR code
QrCode::quick("Hello World", public_path('qr.png'));

// Fluent API
QrCode::create()
    ->text("https://eduplus-bd.com")
    ->output(public_path('qr.png'))
    ->size(512)
    ->errorCorrection('H')
    ->generate();

JSON Data QR Code

$data = json_encode([
    'user_id' => 12345,
    'name' => 'John Doe',
    'email' => 'john@example.com'
]);

QrCode::create()
    ->text($data)
    ->output(storage_path('app/public/user_qr.png'))
    ->size(512)
    ->errorCorrection('H')
    ->generate();

Get Base64 Encoded QR Code

$base64 = QrCode::create()
    ->text("Base64 QR Code")
    ->output(storage_path('app/temp_qr.png'))
    ->generateBase64();

// Use in Blade template
<img src="data:image/png;base64,{{ $base64 }}" />

Controller Example

namespace App\Http\Controllers;

use Eduplus\QrCode;
use Illuminate\Http\Request;

class QrController extends Controller
{
    public function generate(Request $request)
    {
        $qr = QrCode::create()
            ->text($request->input('text'))
            ->output(storage_path('app/public/qr_' . time() . '.png'))
            ->size(400)
            ->generate();

        if ($qr) {
            return response()->json(['success' => true]);
        }

        return response()->json(['success' => false], 500);
    }

    public function generateInline(Request $request)
    {
        $binary = QrCode::create()
            ->text($request->input('text'))
            ->output(storage_path('app/temp_qr.png'))
            ->size(400)
            ->generateAndReturn();

        return response($binary)
            ->header('Content-Type', 'image/png');
    }
}

Barcode Generation

Basic Usage

use Eduplus\BarCode;

// Simple barcode
BarCode::quick("ABC123", public_path('barcode.png'));

// Fluent API
BarCode::create()
    ->text("PRODUCT-001")
    ->output(public_path('barcode.png'))
    ->type('code39')
    ->width(400)
    ->height(120)
    ->generate();

Different Barcode Types

// Code128 (default)
BarCode::create()
    ->text("ABC-123-XYZ")
    ->output(storage_path('app/public/code128.png'))
    ->type('code128')
    ->generate();

// Code39
BarCode::create()
    ->text("PRODUCT-001")
    ->output(storage_path('app/public/code39.png'))
    ->type('code39')
    ->generate();

// EAN-13
BarCode::create()
    ->text("1234567890128")
    ->output(storage_path('app/public/ean13.png'))
    ->type('ean13')
    ->generate();

Get Base64 Encoded Barcode

$base64 = BarCode::create()
    ->text("SKU-12345")
    ->output(storage_path('app/temp_barcode.png'))
    ->generateBase64();

// Use in Blade template
<img src="data:image/png;base64,{{ $base64 }}" />

• quick($text, $output, $type = 'code128', $width = 300, $height = 100) - Quick generation

Error Handling

Both classes expose a public $errors array:

$qr = QrCode::create()
    ->text("Test")
    ->output("qr.png")
    ->generate();

if (!$qr) {
    $instance = QrCode::create();
    print_r($instance->errors);
}

Benefits of This Approach

1. Reduced Package Size: No bundled binaries in each project
2. Single Binary Location: One set of binaries for all Laravel projects
3. Easy Updates: Update binaries once, all projects benefit
4. Flexible Deployment: Configure different paths per environment
5. Server Optimization: Shared binaries reduce disk usage

Requirements

• PHP 7.4 or higher
• Laravel 8.x, 9.x, 10.x, or 11.x
• EduplusQR and EduplusBarcode binaries installed on the system
