x-frame-bypass

Web Component extending IFrame to bypass X-Frame-Options: deny/sameorigin

X-Frame-Bypass

X-Frame-Bypass is a Web Component, specifically a Customized Built-in Element, which extends an IFrame to bypass the X-Frame-Options: deny/sameorigin response header. Normally such headers prevent embedding a web page in an <iframe> element, but X-Frame-Bypass is using a CORS proxy to allow this.

Usage

1. (Optional) Include the Custom Elements with Built-in Extends polyfill for Safari:

    <script src="https://unpkg.com/@ungap/custom-elements-builtin"></script>
   

2. Include the X-Frame-Bypass JS module:

    <script type="module" src="https://unpkg.com/x-frame-bypass"></script>
   

3. Insert the X-Frame-Bypass Custom Element:

    <iframe is="x-frame-bypass" src="https://example.org/"></iframe>
   

Demo

See the Hacker News using X-Frame-Bypass. Supported are current versions of Chrome and Firefox browsers. Edge and Safari do not support Customized Built-in Elements yet.
