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

(Optional) Include the Custom Elements with Built-in Extends polyfill for Safari:
```
 <script src="https://unpkg.com/@ungap/custom-elements-builtin"></script>
```

Include the X-Frame-Bypass JS module:

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

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.
