The author explains how to incorporate dynamic features into a heavily cached website, specifically a Django blog that runs behind Cloudflare with a 15-minute cache header. This setup ensures resilience against traffic spikes. He introduces two main features: edit links visible only to him and a random navigation option for blog tags. The edit links are enabled through JavaScript that checks for a localStorage key called "ADMIN." If this key is set, an edit link appears on the public pages, allowing the author to quickly access the Django admin interface. The random navigation feature lets users click a "Random" button on tag pages to jump to a random post associated with that tag. This button persists in the page header, enabling continuous random navigation within that tag. The implementation relies on localStorage to remember the tag and timestamp of the last click. When a new page loads, JavaScript checks if the timestamp is recent enough—within 5 seconds—to display the button again. The author highlights that this feature was built using Claude Code for web, showcasing a collaborative approach to development. The piece includes specific code snippets and development prompts, providing insight into the coding process and solution evolution.
