Quicklink for WordPress attempts to make navigation to subsequent pages load faster. Embedded with the plugin is a javascript library, which detects links in the viewport, waits until the browser is idle and prefetches the URLs for these links. The library also tries to detect, if the user is on a slow connection or on a data plan.
This plugin builds heavily on the amazing work done by <a href="https://github.com/GoogleChromeLabs/quicklink" rel="nofollow ugc">Google Chrome Labs</a>.

<h4>How it works</h4>
<ul>
<li>Detects links within the viewport (using <a href="https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API" rel="nofollow ugc">Intersection Observer</a>)</li>
<li>Waits until the browser is idle (using <a href="https://developer.mozilla.org/en-US/docs/Web/API/Window/requestIdleCallback" rel="nofollow ugc">requestIdleCallback</a>)</li>
<li>Checks if the user isn’t on a slow connection (using <code>navigator.connection.effectiveType</code>) or has data-saver enabled (using <code>navigator.connection.saveData</code>)</li>
<li>Prefetches URLs to the links (using <a href="https://www.w3.org/TR/resource-hints/#prefetch" rel="nofollow ugc"><code><link rel=prefetch></code></a> or XHR). Provides some control over the request priority (can switch to <code>fetch()</code> if supported).</li>
</ul>

Quicklink for WordPress

Thanks for publishing this. Works really well. Would be nice to see option to loading Quicklink from a CDN.

Great plugin

⚡️ Faster subsequent page-loads by prefetching in-viewport links during idle time.

Server Push provides significant performance gains if used judiciously. However other WordPress plugins that handle server push can actually slow your site as they push files indiscrimentally.
Most push all files enqueued by wordpress to the broswer and use output buffering to achieve this.
However this plugin does it properly by only pushing the the assets that the browser requires for the initial user interaction. Namely the scripts and css in the head of the document.
Note : It requires a web server that supports HTTP/2.

LH HTTP/2 Server Push

Does HTTP/2 Server Push for JavaScript and CSS resources properly.
