<p>Minification & concatenation of JS and CSS files can reduce the file size of your assets, and reduce the number of HTTP requests, helping improve page load times.</p>
<p>The plugin takes a manually defined list of script/style handles, and minifies and concatenates them into a single file which is then cached for future use.</p>
<p><strong>Features.</strong></p>
<ul>
<li>Minifies & concatenates scripts and styles loaded using the WordPress dependency enqueueing system.</li>
<li>Handles scripts loaded in the header & footer.</li>
<li>Complete control – only a manually defined list of files is processed.</li>
<li>Multiple, independently processed files.</li>
<li>Minified files are only loaded if at least one component file should be loaded.</li>
<li>Compatable with localized scripts.</li>
<li>Helper tool – displays a list of scripts and styles enqueued on each page on the front end of the site.</li>
</ul>


MinQueue

Minify & Concatenate Enqueued Scripts & Styles.

<p>Concatenation merges multiple JavaScript files into one. This means the browser downloads 1 file instead of 5, 10, or 20.</p>
<p>Minification removes all unnecessary space from a file. This means you only download the content you actually need.</p>
<p>To speed up your site, most developers will recommend you do both.  But it can be time-consuming and frustrating to set this up – particularly as you install new plugins on your site.</p>
<p>Rather than forcing you to merge and minify files manually, this plugin will do it for you automatically.  No configuration is needed, just activate and go.</p>
<p>This is very much a <strong>beta version</strong> of the plugin and is not expected to be stable. Please report any and all bugs to https://github.com/ericmann/MiniPress/issues.</p>
