Usage

Basic Implementation


const cookieBanner = new NeumorphismCookieBanner();

const cookieBanner = new NeumorphismCookieBanner({
    autoShow: true,
    showDelay: 2000,
    storageKey: 'my_cookie_consent',
    expiryDays: 180,
    onAccept: (consent) => {
        console.log('User accepted cookies:', consent);

        if (consent.analytics) {
            loadGoogleAnalytics();
        }

        if (consent.marketing) {
            loadMarketingPixels();
        }
    },
    onDecline: (consent) => {
        console.log('User declined cookies:', consent);

    },
    onSettingsSave: (consent) => {
        console.log('User saved custom settings:', consent);

    }
});

Advanced Configuration


const advancedBanner = new NeumorphismCookieBanner({
    autoShow: false, // Manual control
    showDelay: 0,
    storageKey: 'advanced_consent',
    expiryDays: 90,

    onAccept: (consent) => {

        initializeAdvancedTracking(consent);
    },
    
    onDecline: (consent) => {

        initializeEssentialOnly();
    },
    
    onSettingsSave: (consent) => {

        loadScriptsBasedOnConsent(consent);
    }
});

function switchTheme(theme) {
    advancedBanner.updateTheme(theme);
}

function showConsentBanner() {
    advancedBanner.show();
}

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