By defining base handlers that extend <code>RequestHandler</code> (or chaining multiple base handlers together), you can modularize logic for common tasks like authentication, user data retrieval, and rate limiting.</p><p>HDIs are designed using the <a href="https://en.wikipedia.org/wiki/Chain-of-responsibility_pattern" target="_blank" rel="noreferrer">Chain of Responsibility pattern</a>, making it easy to handle requests with layered logic.</p><h2 id="🔗-how-it-works" tabindex="-1">🔗 How It Works <a class="header-anchor" href="#🔗-how-it-works" aria-label="Permalink to &quot;🔗 How It Works&quot;">​</a></h2><p>Instead of repeating the same logic in each handler, create abstract handler classes that define common functionality.
