This guide is for sites built and hosted on Framer. Installation has two parts: adding the Coframe script to your site’s Custom Code head, and adding a withCoframe code override to an element that appears on every page (such as your header) to signal when the page has hydrated.

Configure your installation

Set your project ID and options in the editor. Then follow the steps below using the updated code.

01Part 1 — Site settings

  1. In your Framer project, open Site Settings.
  2. Go to the General tab.
  3. Scroll down to Custom Code and find the Start of <head> tag section.
  4. Paste the installation script below into that field.
  5. Click Save.

Replace YOUR_PROJECT_ID with the project ID from your Coframe dashboard.

HTML
<script id='coframe-installation-script'>
  (function () {
    // Early exit for performance testing
    if (/cf_disable/.test(location.search)) return console.warn('[Coframe] Disabled via URL parameter');
  
    // Coframe config
    const config = {
      projectId: 'YOUR_PROJECT_ID',
      startTime: Date.now(),
      timeoutMs: 1000,
      currentUrl: window.location.href,
      waitForHydration: true, // Wait for the framework readiness signal
    };
  
    // Prevent duplicate installation
    const script_id = 'coframe-sdk-js';
    if (document.getElementById(script_id)) return console.warn('[Coframe] SDK already installed');
  
    // Coframe queue setup
    (window.CFQ = window.CFQ || []).push({ config });
  
    // Coframe antiflicker CSS
    const style = document.createElement('style');
    style.id = 'coframe-antiflicker';
    style.textContent =
      ':root { --cf-show: 0;}' +
      'body { opacity: var(--cf-show) !important; transition: opacity 0.2s ease; }'
    function hide() { document.head.appendChild(style); }
    function show() {
      document.documentElement.style.setProperty('--cf-show', '1');
      style.parentNode && style.parentNode.removeChild(style);
    }
    hide(); setTimeout(show, config.timeoutMs);
  
    // Coframe SDK JS
    var edgeUrl = new URL('https://edge.cofra.me/cf.js');
    edgeUrl.searchParams.set('config', encodeURIComponent(JSON.stringify(config)));
  
    const script = document.createElement('script');
    script.id = script_id;
    script.async = true;
    script.src = edgeUrl.toString();
    script.onerror = () => { show(); console.error('[Coframe] SDK failed to load'); };
    document.head.appendChild(script);
  })();
</script>

02Part 2 — withCoframe code override

Select an element that exists on all pages (for example, your site header). Then:

  1. In the right panel, go to Code overrides (bottom right).
  2. Click Add and name the override withCoframe.
  3. Click Edit code.
  4. Replace the file contents with the snippet below.
  5. Save the file.
  6. Apply the withCoframe override to the element you selected.
  7. Publish your site.

You must both create the override and apply it to the element. The override fires a pageHydrated event after Framer’s React tree mounts, which tells the SDK it is safe to apply variant changes.

JSX
import { useEffect } from "react"
import type { ComponentType } from "react"

export function withCoframe(Component): ComponentType {
  return (props) => {
    // @ts-ignore
    useEffect(() => {
      window.CFQ = window.CFQ || [];
      window.CFQ.push({ pageHydrated: true })
    }, [])

    return <Component {...props} />
  }
}

03Verify it is working

After publishing your Framer site:

  • Open the live site in a browser, then open the browser console and confirm there are no [Coframe] error messages.
  • In the Network tab, look for a request to edge.cofra.me/cf.js. A successful 200 response means the SDK loaded correctly.
  • Check that a coframe-sdk-js script element appears in the DOM (you can inspect the <head> in the Elements panel).

For a full walkthrough of how to validate the integration and confirm that Coframe is operating as expected, see Testing and Validation.

04Optional configuration

The default script is designed to work without additional configuration. Once the SDK is installed, you can tune behavior using the following guides:

  • SDK options — timeout, disable conditions, and other core settings
  • Identity settings — associate SDK activity with a known user identity
  • Tracking settings — control which events and page interactions Coframe records
  • Anti-flicker — understand how the anti-flicker mechanism works and how to adjust it for your performance requirements
