WEB-SHOP-HOSTING

This plugin allows you to optimize images from your media library and thus improve the SEO performance of your site. 
This plugin is based on the JPEGOPTIM utility and PNGQUANT utility which must be installed on your host. 
The essence of our plugin is that when it starts, it sorts through all the attachments for the articles of your WP-site 
and processes them right at the place where they are located. 
After that, the attachment is marked as processed, which prevents it from being processed again. 
In the admin page you can view the total number of your images and the number of processed images, 
as well as select the number of images to be processed in one cycle. 
At the moment, the script for optimization is made in the form of a standard wp-action (its name is “startklar_image_optimizer_process”) 
that can be called from another place.
Here is an example of how to call this action: 
 do_action( ‘startklar_image_optimizer_process’ );
For example, for a simple implementation, you can use the “WP Crontrol” plugin (https://ru.wordpress.org/plugins/wp-crontrol/) 
 by which you can create a cron task that can optimize one image every minute. 
This tactic was chosen in order to process all the files of the site without introducing excessive load to the site 
(since the native cron in WP is activated by hits and has a runtime limit, like similar http sessions of this host).
Screenshot #1 shows how easy it is to set up a cron-task.

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>

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.
