Usage

Basic Implementation


const cookieToast = new CornerToastCookieBanner();

const cookieToast = new CornerToastCookieBanner({
    position: 'bottom-right',
    autoShow: true,
    autoDismiss: true,
    dismissDelay: 15000,
    onAccept: (preferences) => {
        console.log('User accepted cookies:', preferences);

    },
    onDecline: (preferences) => {
        console.log('User declined optional cookies:', preferences);

    }
});

Programmatic Control


cookieToast.show();

cookieToast.hide();

cookieToast.setPosition('top-left');

const preferences = cookieToast.getPreferences();

cookieToast.reset();

Advanced Features

Multiple Toast Support


const toasts = [
    new CornerToastCookieBanner({ position: 'top-right', autoDismiss: true }),
    new CornerToastCookieBanner({ position: 'bottom-left', autoDismiss: false })
];

toasts.forEach(toast => toast.show());

Custom Toast Content

const customToast = new CornerToastCookieBanner({
    customContent: {
        title: 'Privacy Notice',
        message: 'We value your privacy and use cookies to improve your experience.',
        icon: '🔒',
        badge: 'Required'
    }
});

Integration with Analytics

const analyticsToast = new CornerToastCookieBanner({
    onAccept: (preferences) => {
        if (preferences.analytics) {

            gtag('config', 'GA_MEASUREMENT_ID');
        }
        if (preferences.marketing) {

            fbq('init', 'FACEBOOK_PIXEL_ID');
        }
    },
    onDecline: (preferences) => {

        if (!preferences.analytics) {
            window['ga-disable-GA_MEASUREMENT_ID'] = true;
        }
    }
});

Troubleshooting

Common Issues

Toast not appearing:

Check if consent already exists in localStorage
Verify autoShow is set to true
Ensure showDelay is appropriate

Styling conflicts:

Use CSS specificity or !important declarations
Check for conflicting z-index values
Verify CSS custom properties are supported

Performance issues:

Reduce animation complexity for older devices
Implement lazy loading for large applications
Consider using CSS containment

Debug Mode

const debugToast = new CornerToastCookieBanner({
    debug: true, // Enable console logging
    onAccept: (preferences) => {
        console.log('Debug: Cookies accepted', preferences);
    }
});

Examples

E-commerce Integration

const ecommerceToast = new CornerToastCookieBanner({
    position: 'bottom-right',
    onAccept: (preferences) => {
        if (preferences.marketing) {

            enableProductRecommendations();
        }
        if (preferences.analytics) {

            enableUserTracking();
        }
    }
});

Blog/Content Site

const blogToast = new CornerToastCookieBanner({
    position: 'top-left',
    autoDismiss: true,
    dismissDelay: 12000,
    onAccept: (preferences) => {
        if (preferences.functional) {

            enableReadingProgress();
        }
    }
});

SaaS Application

const saasToast = new CornerToastCookieBanner({
    position: 'top-right',
    enableStacking: false,
    onSettings: () => {

        openPrivacySettings();
    },
    onAccept: (preferences) => {

        updateUserPrivacySettings(preferences);
    }
});

Migration Guide


if (window.existingCookieBanner) {
    window.existingCookieBanner.destroy();
}

const newToast = new CornerToastCookieBanner({

    storageKey: 'legacy_cookie_consent', // Use existing storage key
    onAccept: (preferences) => {

        migrateLegacyTracking(preferences);
    }
});

Version Updates


const currentVersion = '1.0.0';
const storedVersion = localStorage.getItem('toast_banner_version');

if (storedVersion !== currentVersion) {

    cookieToast.reset();
    localStorage.setItem('toast_banner_version', currentVersion);
}

Security Considerations

Data Protection

All consent data is stored locally in the user’s browser
No personal data is transmitted to external servers
Consent timestamps are stored for audit purposes
Data can be easily exported or deleted

XSS Prevention


function sanitizeInput(input) {
    const div = document.createElement('div');
    div.textContent = input;
    return div.innerHTML;
}
