In March 2025, Fotis Rallis developed hash-based routing improvements for Single Page Applications embedded via iframe in the nextcloud/external repository. He implemented JavaScript logic to support internal navigation using hash fragments, ensuring that navigation state is preserved when users interact with internal links. His approach included updating the iframe source in response to URL hash changes, maintaining consistent navigation behavior within the embedded application. This work focused on front end development and addressed the challenge of deep linking and state management for SPAs in an iframe context. The feature was delivered across two commits and did not involve bug fixes.
