Pros of php-qrcode

• More extensive documentation and examples
• Supports a wider range of output formats (PNG, GIF, JPG, SVG, etc.)
• Actively maintained with frequent updates

Cons of php-qrcode

• Larger codebase, potentially more complex to integrate
• Requires PHP 7.4 or higher, which may limit compatibility with older systems

Code Comparison

BaconQrCode:

$renderer = new ImageRenderer(
    new RendererStyle(400),
    new ImagickImageBackEnd()
);
$writer = new Writer($renderer);
$writer->writeFile('Hello World!', 'qrcode.png');

php-qrcode:

$options = new QROptions([
    'outputType' => QRCode::OUTPUT_IMAGE_PNG,
    'eccLevel'   => QRCode::ECC_L,
]);
$qrcode = new QRCode($options);
$qrcode->render('Hello World!', 'qrcode.png');

Both libraries offer similar functionality for generating QR codes, but php-qrcode provides more flexibility in terms of output formats and customization options. BaconQrCode has a simpler API and may be easier to integrate for basic use cases. The choice between the two depends on specific project requirements and the desired level of control over QR code generation.

Pros of qr-code

• More actively maintained with frequent updates
• Supports a wider range of output formats (PNG, SVG, EPS, PDF)
• Offers additional features like logo insertion and styling options

Cons of qr-code

• Larger package size due to additional dependencies
• Slightly more complex API for basic usage
• May have a steeper learning curve for beginners

Code Comparison

BaconQrCode:

use BaconQrCode\Renderer\ImageRenderer;
use BaconQrCode\Renderer\Image\ImagickImageBackEnd;
use BaconQrCode\Writer;

$renderer = new ImageRenderer(
    new RendererStyle(400),
    new ImagickImageBackEnd()
);
$writer = new Writer($renderer);
$writer->writeFile('Hello World!', 'qrcode.png');

qr-code:

use Endroid\QrCode\QrCode;
use Endroid\QrCode\Writer\PngWriter;

$qrCode = QrCode::create('Hello World!')
    ->setSize(300)
    ->setMargin(10);
$writer = new PngWriter();
$result = $writer->write($qrCode);
$result->saveToFile('qrcode.png');

Both libraries offer straightforward ways to generate QR codes, but qr-code provides more flexibility in terms of customization and output options. BaconQrCode has a simpler API for basic usage, while qr-code offers more advanced features at the cost of slightly increased complexity.

Pros of qrcode-generator

• Multi-language support: Implementations available in JavaScript, Java, and other languages
• Lightweight and simple to use
• Supports various output formats (Canvas, SVG, Table)

Cons of qrcode-generator

• Less actively maintained compared to BaconQrCode
• Fewer advanced features and customization options
• Limited documentation and examples

Code Comparison

BaconQrCode:

use BaconQrCode\Renderer\ImageRenderer;
use BaconQrCode\Renderer\Image\ImagickImageBackEnd;
use BaconQrCode\Renderer\RendererStyle\RendererStyle;
use BaconQrCode\Writer;

$renderer = new ImageRenderer(
    new RendererStyle(400),
    new ImagickImageBackEnd()
);
$writer = new Writer($renderer);
$writer->writeFile('Hello World!', 'qrcode.png');

qrcode-generator (JavaScript):

var qr = qrcode(4, 'L');
qr.addData('Hello World!');
qr.make();
var img = qr.createImgTag(4);
document.getElementById('qrcode').innerHTML = img;

Both libraries offer straightforward ways to generate QR codes, but BaconQrCode provides more advanced rendering options and customization. qrcode-generator is simpler to use but offers fewer features.

Pros of qrcodejs

• Lightweight and easy to use, with a simple JavaScript implementation
• Supports various output formats, including SVG and Canvas
• No external dependencies, making it ideal for client-side applications

Cons of qrcodejs

• Limited customization options compared to BaconQrCode
• Lacks support for more advanced QR code features and error correction levels
• Not actively maintained, with the last update in 2014

Code Comparison

BaconQrCode (PHP):

use BaconQrCode\Renderer\ImageRenderer;
use BaconQrCode\Renderer\Image\ImagickImageBackEnd;
use BaconQrCode\Renderer\RendererStyle\RendererStyle;
use BaconQrCode\Writer;

$renderer = new ImageRenderer(
    new RendererStyle(400),
    new ImagickImageBackEnd()
);
$writer = new Writer($renderer);
$writer->writeFile('Hello World!', 'qrcode.png');

qrcodejs (JavaScript):

var qrcode = new QRCode(document.getElementById("qrcode"), {
    text: "Hello World!",
    width: 128,
    height: 128,
    colorDark : "#000000",
    colorLight : "#ffffff",
    correctLevel : QRCode.CorrectLevel.H
});

Pros of QR-Code-generator

• Supports multiple programming languages (C++, Java, JavaScript, Python, and more)
• Provides extensive documentation and examples
• Offers more advanced features like error correction level control

Cons of QR-Code-generator

• Less actively maintained (last update was over a year ago)
• Requires more manual setup and integration
• May have a steeper learning curve for beginners

Code Comparison

BaconQrCode:

$renderer = new ImageRenderer(
    new RendererStyle(400),
    new ImagickImageBackEnd()
);

$writer = new Writer($renderer);
$writer->writeFile('Hello World!', 'qrcode.png');

QR-Code-generator:

import qrcode

qr = qrcode.QRCode(version=1, box_size=10, border=5)
qr.add_data('Hello World!')
qr.make(fit=True)

img = qr.make_image(fill_color="black", back_color="white")
img.save('qrcode.png')

Both libraries offer straightforward ways to generate QR codes, but QR-Code-generator provides more flexibility across multiple programming languages. BaconQrCode, being PHP-specific, offers a simpler integration for PHP projects. The choice between the two depends on the specific project requirements, programming language preferences, and the need for advanced features.
