🌐 iFrame Notifier for Nginx

This Ansible role injects a small JavaScript snippet into your HTML responses that enables parent pages to get notified whenever the iframe’s location changes and forces external links to open in a new tab.

Features

  • Location Change Notification
    Uses postMessage to inform the parent window of any URL changes inside the iframe (including pushState/popState events) for seamless SPA support.

  • External Link Handling
    Automatically sets target="_blank" and rel="noopener" on links pointing outside your primary domain to improve security and user experience.

  • Easy CSP Integration
    Calculates a CSP hash for the injected script so you can safely allow it via your Content Security Policy.
