Usage

Basic Implementation

// Initialize with default settings
const cookieBanner = new NeonCookieBanner();

// Initialize with custom options
const cookieBanner = new NeonCookieBanner({
    autoShow: true,
    showDelay: 2000,
    storageKey: 'my_cookie_consent',
    expiryDays: 180,
    onAccept: (consent) => {
        console.log('User accepted cookies:', consent);
        // Load analytics scripts
        if (consent.analytics) {
            loadGoogleAnalytics();
        }
        // Load marketing scripts
        if (consent.marketing) {
            loadMarketingPixels();
        }
    },
    onDecline: (consent) => {
        console.log('User declined cookies:', consent);
        // Only load essential functionality
    },
    onSettingsSave: (consent) => {
        console.log('User saved custom settings:', consent);
        // Load scripts based on specific preferences
    }
});

Advanced Configuration

// Custom styling and behavior
const advancedBanner = new NeonCookieBanner({
    autoShow: false, // Manual control
    showDelay: 0,
    storageKey: 'advanced_consent',
    expiryDays: 90,
    
    // Custom callbacks
    onAccept: (consent) => {
        // Advanced analytics setup
        initializeAdvancedTracking(consent);
    },
    
    onDecline: (consent) => {
        // Minimal tracking setup
        initializeEssentialOnly();
    },
    
    onSettingsSave: (consent) => {
        // Granular script loading
        loadScriptsBasedOnConsent(consent);
    }
});

// Manual control
function showConsentBanner() {
    advancedBanner.show();
}

// Check current consent status
function checkConsentStatus() {
    const consent = advancedBanner.getConsent();
    if (consent) {
        console.log('Current consent:', consent);
    } else {
        console.log('No consent given yet');
    }
}
