Live Data, Refreshed Every Minute

Speedy clears a page when Craft content on it changes. Data from outside Craft, such as exchange rates, stock from another system or the weather, changes without Craft knowing. Rebuild those pages on a timer.

The template

{# templates/rates.twig #}
{% extends '_layout' %}

{# Rebuild this page every minute #}
{% do craft.speedy.ttl(60) %}

{% set rates = craft.app.cache.getOrSet('fx-rates', () => fetchRates(), 60) %}

{% block content %}
  <h1>Today’s rates</h1>
  <table>
    {% for code, rate in rates %}
      <tr><th>{{ code }}</th><td>{{ rate|number_format(4) }}</td></tr>
    {% endfor %}
  </table>
  <p class="small">Updated {{ now|date('H:i') }}</p>
{% endblock %}

What happens

• The page is cached, then rebuilt in the background a minute later. Visitors never wait for it.
• Saving entries shown on the page still clears it straight away.
• If the template calls ttl() more than once, such as from an include, the shortest time wins.

Only one part is live

If most of the page is ordinary content and only a small box is live, keep the page cached and include the box dynamically instead:

{{ craft.speedy.dynamic('_parts/rates-box') }}
