setupCookieConsent({
  serverMode: true,
  apiUrl: 'https://your-api.com/consent',
  userToken: 'abc123',
  categories: {
    label: 'Analytics',
      description: 'Helps us understand user behavior.',
      customizable: true,
      scripts: [
        {
          src: 'https://www.googletagmanager.com/gtag/js?id=G-XXXXXXX',
          name: 'Google Tag Manager'
        }
      ],
    },
    marketing: {
      label: 'Marketing',
      description: 'Tracks ads and conversions.',
      customizable: true,
      scripts: [
        {
          inline: `
            !function(f,b,e,v,n,t,s)
            {if(f.fbq)return;n=f.fbq=function(){n.callMethod ?
            n.callMethod.apply(n,arguments):n.queue.push(arguments)};
            if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';
            n.queue=[];t=b.createElement(e);t.async=!0;
            t.src=v;s=b.getElementsByTagName(e)[0];
            s.parentNode.insertBefore(t,s)}(window, document,'script',
            'https://connect.facebook.net/en_US/fbevents.js');
            fbq('init', 'YOUR_PIXEL_ID'); 
            fbq('track', 'PageView');
          `,
          name: 'Facebook Pixel'
        }
      ]
    }
  }
});

Then in your layout

<Banner
  message="We use cookies 🍪 to improve your experience."
  buttons={{ customize: "Customize" }}
  customizeMode="modal"
/>

<Modal>
  <YourPreferenceComponent /> {/* use useConsentCategories() hook here */}
</Modal>

<script>
  import { setupCookieConsent, showBanner } from '@darmiuskz/cookie-consent-manager';
  window.CookieConsent.setupCookieConsent({
    serverMode: false,
    categories: {
      analytics: {
        label: 'Analytics',
        description: 'Tracks how users interact with the site',
        customizable: true,
        scripts: [
          {
            src: 'https://www.googletagmanager.com/gtag/js?id=G-XXXXXXX',
            name: 'Google Tag Manager'
          },
        ]
      }
    }
  });

  window.CookieConsent.showBanner({
    message: "We use cookies 🍪",
    buttons: {
      customize: "Customize"
    },
    customizeMode: "page",
    customizePageUrl: "/cookie-settings"
  });
</script>

🛠️ Custom Modals in Native JS

<script>
import { injectCustomModal, getConsentHelpers, getConsentCategories } from 'cookie-consent-manager';
  const categories = getConsentCategories();

  const html = `
    <div class="my-cookie-modal">
      <h2>Cookie Preferences</h2>
      ${categories.map(cat => `
        <label>
          <input type="checkbox" name="${cat.key}" ${cat.checked ? 'checked' : ''} />
          ${cat.label}
        </label>
      `).join('')}
      <button onclick="saveMyConsent()">Save</button>
      <button onclick="window.CookieConsent.getConsentHelpers().rejectAll()">Reject All</button>
    </div>
  `;

  function saveMyConsent() {
    const selected = Array.from(document.querySelectorAll('input[type=checkbox]:checked')).map(i => i.name);
    getConsentHelpers().save(selected);
    document.querySelector('.my-cookie-modal')?.remove();
  }

  injectCustomModal(html);
