ADDING DYNAMIC FEATURES TO AN AGGRESSIVELY CACHED WEBSITE

Summary from the TLDR Dev newsletter

This dev implemented dynamic features on his aggressively cached website, which uses Cloudflare with a 15-minute cache header. He used localStorage and client-side JavaScript for features that bypass full-page caching. Examples include "Edit" links visible only to the administrator based on a `localStorage` key, and a "Random" button for navigating posts within a specific tag.
