Hydration

Fetch HTML from the server and inject it into any element without a full page reload. Use w-get with w-target and w-swap to control where and how content is inserted.

Compare hydration (no page reload) vs traditional links (full page reload):

Hydrate:

Reload: replace prepend append

Hydration (No Page Reload)


      <button

        w-get="/partials/notification"

        w-target="#target"

        w-swap="replace"

      >Load</button>

Traditional Link (Full Page Reload)


      <a href="/page?mode=replace">

        Load

      </a>

Partial Component with Session Counter


    // File: /partials/notification-counter.html


    <what>

    session.notification_count += 1

    </what>


    <div class="notification">

      <strong>Notification #session.notification_count#</strong>

      <p>Injected without reloading the page</p>

    </div>

The session.var += 1 directive automatically increments the session variable before rendering. The counter persists across requests for each user's session.
