Supercharge Your Symfony App with Smart Device Detection: Meet EprofosUserAgentAnalyzerBundle

The Challenge of Modern Web Development

Have you ever struggled with delivering the right experience to users across different devices? In an era where users switch between phones, tablets, and desktops seamlessly, detecting devices accurately can be a major headache. That's where EprofosUserAgentAnalyzerBundle comes in.

What Makes This Bundle Special?

Unlike traditional user agent parsers, EprofosUserAgentAnalyzerBundle offers:

1. Zero-Configuration Setup

composer require eprofos/user-agent-analyzer

That's it! The bundle auto-configures itself in your Symfony application.

2. Crystal-Clear Twig Integration

Transform this complex detection:

if (strpos($_SERVER['HTTP_USER_AGENT'], 'Mobile') !== false) {
    // Is it really mobile? What about tablets?
    // What about desktop mode on mobile?
}

Into this elegant solution:

{% if is_mobile() %}
    <div class="mobile-view">
        {{ include('components/mobile_navigation.html.twig') }}
    </div>
{% endif %}

3. Comprehensive Device Intelligence

use Eprofos\UserAgentAnalyzerBundle\Service\UserAgentAnalyzer;

class ResponsiveController
{
    public function index(UserAgentAnalyzer $analyzer)
    {
        $result = $analyzer->analyzeCurrentRequest();

        // Rich device information
        $deviceInfo = [
            'type' => $result->getDeviceType(),
            'os' => [
                'name' => $result->getOsName(),
                'version' => $result->getOsVersion(),
                'is64bit' => $result->is64BitsMode()
            ],
            'browser' => [
                'name' => $result->getBrowserName(),
                'version' => $result->getBrowserVersion(),
                'isWebview' => $result->isBrowserAndroidWebview() || $result->isBrowserIosWebview()
            ]
        ];

        // Use this information to:
        // 1. Optimize content delivery
        // 2. Enable platform-specific features
        // 3. Track usage analytics
    }
}

Real-World Use Cases

1. E-commerce Platform Optimization

{# Optimize product gallery based on device #}
{% if is_mobile() %}
    {# Show swipeable gallery #}
    {{ include('product/mobile_gallery.html.twig') }}
{% elseif is_tablet() %}
    {# Show touch-optimized grid #}
    {{ include('product/tablet_gallery.html.twig') }}
{% else %}
    {# Show full desktop experience #}
    {{ include('product/desktop_gallery.html.twig') }}
{% endif %}

2. Progressive Web App Features

{# Enable platform-specific features #}
{% if is_android() %}
    {# Android-specific PWA features #}
    {{ include('pwa/android_install_prompt.html.twig') }}
{% elseif is_ios() %}
    {# iOS-specific PWA features #}
    {{ include('pwa/ios_install_prompt.html.twig') }}
{% endif %}

3. Performance Optimization

use Eprofos\UserAgentAnalyzerBundle\Service\UserAgentAnalyzer;

class MediaController
{
    public function serveVideo(UserAgentAnalyzer $analyzer)
    {
        $result = $analyzer->analyzeCurrentRequest();

        // Optimize video delivery
        $videoConfig = match(true) {
            $result->isMobile() => [
                'quality' => 'adaptive',
                'preload' => 'metadata',
                'format' => 'mp4'
            ],
            $result->isTablet() => [
                'quality' => 'high',
                'preload' => 'auto',
                'format' => 'mp4'
            ],
            default => [
                'quality' => 'highest',
                'preload' => 'auto',
                'format' => 'webm'
            ]
        };

        return $this->render('video/player.html.twig', [
            'config' => $videoConfig
        ]);
    }
}

Advanced Features Deep Dive

1. Browser Capability Detection

$result = $analyzer->analyzeCurrentRequest();

// Check for specific browser features
if ($result->getBrowserChromiumVersion()) {
    // Enable Chrome-specific features
}

if ($result->getBrowserWebkitVersion()) {
    // Enable WebKit-specific features
}

// Check for desktop mode on mobile
if ($result->isBrowserDesktopMode()) {
    // Adjust layout accordingly
}

2. Operating System Intelligence

// Detailed OS information
$osInfo = match($result->getOsName()) {
    'Windows' => [
        'version' => $result->getOsVersion(),
        'family' => $result->getOsFamily(),
        'is64bit' => $result->is64BitsMode()
    ],
    'macOS' => [
        'version' => $result->getOsVersion(),
        'codename' => $result->getOsCodename(), // e.g., "Monterey"
        'architecture' => $result->is64BitsMode() ? 'x64' : 'x86'
    ],
    default => [
        'name' => $result->getOsName(),
        'version' => $result->getOsVersion()
    ]
};

Performance Considerations

The bundle is designed with performance in mind:

1. Results are cached for subsequent requests
2. Lightweight pattern matching
3. No external API calls
4. Minimal memory footprint
