Bacon Qr Code Laravel Package
bacon/bacon-qr-code

BaconQrCode is a QR code generator for PHP.
Frequently asked questions about Bacon Qr Code
- How do I install BaconQrCode in a Laravel project?
- Run `composer require bacon/bacon-qr-code` in your project root. Ensure PHP 8.1+ is used (Laravel 9/10). No additional Laravel-specific setup is required beyond Composer autoloading.
- Which Laravel versions does BaconQrCode support?
- The package works with Laravel 9+ (PHP 8.1+) and Laravel 10+ (PHP 8.2+). For Laravel 8 (PHP 8.0), use version 2.x of BaconQrCode, which supports PHP 7.1+.
- Can I generate QR codes dynamically in a Laravel API response?
- Yes. Use `Response::make($writer->writeString($text), 200, ['Content-Type' => 'image/png'])` in your controller. For SVG/EPS, adjust the Content-Type header accordingly.
- What are the performance implications of using Imagick vs. GDLib?
- Imagick offers higher quality but may introduce minor white pixel artifacts. GDLib is faster but lacks gradients/curves. Benchmark both for your use case—GDLib is ideal for bulk generation, while Imagick/SVG suits high-quality needs.
- How do I handle missing PHP extensions (e.g., Imagick) in production?
- Fallback to `SvgImageBackEnd` or `GDLibRenderer` in your code. For critical deployments, queue QR generation as a job (e.g., `ShouldQueue`) to handle extension unavailability gracefully.
- Can I customize QR code colors or add logos?
- BaconQrCode supports basic styling via `RendererStyle` (e.g., size, margins). For advanced customization like logos or gradients, use SVG output or combine with Imagick post-processing.
- Is BaconQrCode suitable for high-volume QR generation (e.g., invoices)?
- Yes, but test performance first. For bulk operations, queue jobs or cache generated QR codes. The package’s Reed-Solomon encoding is optimized but may introduce latency—compare with alternatives like `endroid/qr-code` if needed.
- How do I integrate BaconQrCode with Laravel’s service container?
- Bind the `Writer` class to an interface (e.g., `QrCodeGenerator`) in `AppServiceProvider`. Example: `app()->bind(QrCodeGenerator::class, fn() => new Writer(new ImageRenderer(...)));`. This enables mocking for tests.
- Are there alternatives to BaconQrCode for Laravel?
- Yes. Consider `endroid/qr-code` (more features, slower) or `chillerlan/php-qrcode` (lightweight, GD-only). BaconQrCode stands out for its ZXing-based encoding and multi-backend support (Imagick/SVG/GD).
- How do I test QR code generation in Laravel?
- Mock the `Writer` interface in unit tests. For integration tests, verify output files or responses. Use `Storage::fake()` to test file-based generation. Example: `assertFileExists(storage_path('app/qrcodes/test.png'));`
