<p>This plugin supports a few features that may improve the performance of page loading and rendering in the browser:</p>
<ul>
<li>Concatenate CSS</li>
<li>Concatenate JavaScript</li>
<li>Execution timing of non-critical scripts
<ul>
<li>Note: Changing script execution timing can be risky and will not work well for all sites.</li>
</ul>
</li>
</ul>
<h3>Testing</h3>
<p>To test features without enabling them for the entire site, you may append query params to a WordPress post or page URL. For example, to test enabling JavaScript concatenation for <code>https://example.com/blog/</code>, you can use the URL <code>https://example.com/blog/?concat-js=1</code>.</p>
<p>Supported query params:</p>
<ul>
<li><code>concat-css</code> controls CSS concatenation. Values: <code>1</code> for ON and <code>0</code> for OFF.</li>
<li><code>concat-js</code> controls JavaScript concatenation. Values: <code>1</code> for ON and <code>0</code> for OFF.</li>
<li><code>load-mode-js</code> controls how non-critical JavaScript are loaded. Values: ‘defer’ for <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script#attr-defer" rel="nofollow ugc">deferred</a>, ‘async’ for <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script#attr-async" rel="nofollow ugc">async loading</a>, any other value indicates the feature should be disabled.</li>
</ul>
<h4>PHPUnit (Docker)</h4>
<p>You can run the PHPUnit tests locally using Docker (no local MySQL required).</p>
<p>First time (or after changing DB credentials):</p>
<pre><code>docker compose down -v
</code></pre>
<p>Run tests:</p>
<pre><code>docker compose up --build --abort-on-container-exit --exit-code-from tests
</code></pre>
<p>Optional overrides (examples):</p>
<ul>
<li><code>WP_VERSION=6.5 docker compose up --build --abort-on-container-exit --exit-code-from tests</code></li>
<li><code>PHP_VERSION=7.4 docker compose up --build --abort-on-container-exit --exit-code-from tests</code></li>
<li><code>PHPUNIT_VERSION=9.6.20 docker compose up --build --abort-on-container-exit --exit-code-from tests</code></li>
</ul>
