<p><strong>Site Scripts & Speed Manager</strong> gives you full visibility and control over every JavaScript file loading on your WordPress site.</p>
<p>Most performance plugins offer a blanket “defer all scripts” checkbox — then you spend hours figuring out what broke. This plugin takes a different approach: <strong>see first, then optimize.</strong></p>
<ol>
<li><strong>Crawl your entire site</strong> or scan a single page to discover every script</li>
<li><strong>See exactly</strong> what each script is, where it comes from, how it currently loads, and which pages it appears on</li>
<li><strong>Choose per-script</strong>: Defer, Async, or None — with visual badges, filter tabs, and live search</li>
<li><strong>Master kill switch</strong> — if anything breaks, flip it off instantly. No cache clearing needed.</li>
</ol>
<h4>Full Site Crawl</h4>
<p>Don’t just scan one page — crawl your <strong>entire site</strong> with a single click. The plugin automatically discovers your pages, posts, and category archives (up to 50 pages, 10 posts, and 5 categories), scans each one for scripts, and merges the results into a unified view. An animated progress bar shows crawl status in real-time.</p>
<h4>Per-Page Script Tracking</h4>
<p>After a full site crawl, every script shows how many pages it appears on. Hover over the count to see the list of page paths. Scripts that only load on inner pages (not the homepage) are highlighted with an <strong>“inner only”</strong> badge, so you can immediately spot page-specific scripts from plugins like WooCommerce, contact forms, or page builders.</p>
<h4>Per-Script Loading Control</h4>
<p>Each discovered script gets its own dropdown: <strong>Defer</strong>, <strong>Async</strong>, or <strong>None</strong>. No blanket rules — you choose exactly how each script loads based on what it is and what it does. Color-coded dropdowns make it easy to see your choices at a glance: blue for Defer, amber for Async.</p>
<h4>Protected Scripts</h4>
<p>jQuery Core and jQuery Migrate are automatically locked and cannot be deferred or async’d. Deferring jQuery breaks the majority of WordPress sites, so the plugin prevents you from making that mistake. Protected scripts show a lock icon and their dropdowns are disabled.</p>
<h4>Smart Script Classification</h4>
<p>Every script is tagged with a visual badge:</p>
<ul>
<li>🔒 <strong>Protected</strong> — jQuery core / jQuery Migrate — locked, cannot be modified</li>
<li><strong>WP</strong> (blue) — Registered via wp_enqueue_script() — fully controllable with Defer, Async, or None</li>
<li><strong>EXT</strong> (amber) — Hardcoded or external scripts — shown for visibility only (must be modified at source)</li>
</ul>
<h4>Filter Tabs & Live Search</h4>
<p>Filter the script table by category:</p>
<ul>
<li><strong>All</strong> — every script found</li>
<li><strong>Controllable</strong> — WP-enqueued scripts you can modify</li>
<li><strong>External</strong> — hardcoded/third-party scripts (display only)</li>
<li><strong>Protected</strong> — locked scripts (jQuery)</li>
<li><strong>Inner-Page Only</strong> — scripts not found on the homepage (appears after a full site crawl)</li>
</ul>
<p>Type in the search box to instantly filter by handle name or source URL. Filters and search work together.</p>
<h4>Stats Dashboard</h4>
<p>A real-time stats bar shows total scripts, controllable count, deferred count, async count, external count, and pages scanned (after a full crawl). Stats update automatically when you change strategies.</p>
<h4>Bulk Actions</h4>
<ul>
<li><strong>Defer All</strong> — sets every controllable script to Defer in one click</li>
<li><strong>Reset All</strong> — clears all strategies back to None</li>
<li><strong>Save Settings</strong> — persists your choices to the database</li>
</ul>
<h4>Master Kill Switch</h4>
<p>A prominent on/off toggle at the top of the page. When active, the plugin modifies script tags on the front-end. When off, all scripts load normally — no changes are applied, no cache clearing needed, and your saved settings are preserved for when you turn it back on.</p>
<h4>Built-in Strategy Reference</h4>
<p>Detailed cards built right into the admin page explain exactly what each loading strategy does:</p>
<ul>
<li><strong>None (Default)</strong> — The browser downloads and runs the script immediately, pausing HTML parsing. Required for jQuery and scripts that must run before the page renders.</li>
<li><strong>Defer (Recommended)</strong> — The browser downloads in parallel with HTML parsing, then executes after the document is fully parsed. Maintains execution order among deferred scripts. Best for most scripts.</li>
<li><strong>Async</strong> — The browser downloads in parallel, then executes as soon as the download is complete — regardless of HTML parsing state. Execution order is not guaranteed. Best only for fully independent scripts like analytics and tracking pixels.</li>
</ul>
<p>Each card includes detailed “When to use”, “Impact”, and “Caution” guidance.</p>
<h4>Modern Admin UI</h4>
<p>A completely custom-built interface with CSS custom properties for consistent theming, color-coded dropdowns, change highlighting (modified rows turn amber until saved), responsive layout for all screen sizes, animated progress bar during crawls, and hover-to-expand source URLs in the table.</p>
<h4>Zero Bloat</h4>
<p>No external API calls. No tracking or analytics. No ads, banners, or upsells. No additional database tables. All settings are stored in a single wp_options row.</p>
<h4>Who Is This For?</h4>
<ul>
<li><strong>WordPress developers</strong> who want granular script control without writing code</li>
<li><strong>Site owners</strong> looking to improve Core Web Vitals and page speed scores</li>
<li><strong>Agencies</strong> managing multiple client sites that need per-site optimization</li>
<li><strong>Anyone</strong> tired of blindly deferring scripts and breaking things</li>
</ul>

<h3>Deprecated</h3>
<p>This plugin is deprecated and will be removed in the future.<br />
It was coded back in 2019 when WpRocket did not have asynchronous support for CSS.<br />
Although this plugin operates at a lower level (main php buffer), which helps apply loadsCSS to ALL styles regardless of whether they conform to wp_enqueue or not, <strong>we recommend</strong> instead using WpRocket’s system: <a href="https://docs.wp-rocket.me/article/1266-load-css-asynchronously" rel="nofollow ugc">Load CSS Asynchronously</a>.</p>
<h3>Description</h3>
<p>Simple high performance plugin to enhance WP Rocket’s css output to use the loadCSS preload polyfill.<br />
This will ensure <strong>any css</strong> being loaded via the page output <strong>is deferred</strong>, and utilizing a preload [rel] attribute.<br />
Note: This will not affect admin pages. It’s designed only to process front-end pages.</p>
<p>It is recommended to enable the WP Rocket setting for “Optimize CSS”, which will provide your pages with inline Critical-CSS.<br />
That way an unstyled flash is not seen on page load (if properly configured of course).</p>
<p><strong>This plugin will boost your <a href="https://developers.google.com/web/tools/lighthouse/" rel="nofollow ugc">Lighthouse</a> and <a href="https://developers.google.com/speed/pagespeed/insights/" rel="nofollow ugc">PageSpeed Insight</a> scores.</strong></p>
<h3>Plugin Mission</h3>
<p>We hope that <a href="https://wp-rocket.me/" rel="nofollow ugc">WP Rocket</a> will implement this as a <strong>feature</strong> of their plugin.<br />
The existing <a href="https://docs.wp-rocket.me/article/1266-load-css-asynchronously" rel="nofollow ugc">Load CSS Asynchronously</a> only works for supported wp_enqueue styles, which not all plugins/themes properly utilize.<br />
For normal users, we recommend using WP Rocket’s system instead of this plugin.</p>
<h3>Requirements:</h3>
<ul>
<li>If you intend for logged-in users to see the effect, you must enable WP-Rocket’s setting called “caching for Logged-In Users”</li>
<li>Alternatively, you can run the plugin without WP-Rocket, despite it’s intended purpose.    (>^.^)></li>
</ul>
<h3>Features:</h3>
<ul>
<li><a href="https://github.com/filamentgroup/loadCSS/tree/v2.0.1" rel="nofollow ugc">FilamentGroup’s LoadCSS(v2.0.1)</a> inline injector<br />
(optional – see settings page next to WP Rocket), <em>triggered via wp_head</em>  </li>
<li>High performance Regular Expression approach to process WP Rocket’s (php’s) output buffer, to replace stylesheets with the appropriate loadCSS syntax  </li>
<li>Option to enable the buffer processor when you don’t have WP Rocket installed.<br />
** This will respect AMP pages, and Yoast Sitemap output (by not executing). No other considerations have been implemented.  </li>
</ul>
<p>No fluff. Just a robust loadCSS implementation.</p>
<p>You can see how it works, & measure the performance, with this(via repl.it): <a href="https://repl.it/@ensemblebd/WPRocketLoadCSSMeasurement" rel="nofollow ugc">Run the Plugin’s code</a><br />
Just paste your own page’s url or html into the appropriate variable @ the top.</p>
<p>And you can test this plugin’s regex as well: <a href="https://regex101.com/r/xsugT7/1/" rel="nofollow ugc">WordPress.com html – links filtered by regex</a></p>
<p>Github link is here: <a href="https://github.com/ensemblebd/wp-rocket-loadcss" rel="nofollow ugc">Click</a></p>
<h3>Last tested with:</h3>
<ul>
<li>WP Rocket 3.13.x</li>
<li>WordPress 6.2.x</li>
</ul>
<h3>Dependencies</h3>
<ul>
<li>WP Rocket  (optional via settings)  </li>
<li>file_get_contents() php function  (if included loadCSS lib is used via options — default = yes)</li>
