WP-JSHRINK

JShrink minifier implemented for WordPress. Combines footer scripts equeued by wp_enqueue_script into a single minified js file. Check the FAQ section for more info about the plugin.

Important note: only footer scripts which are equeued by wp_enqueue_script with the fifth parameter set to ‘true’ are minified by this plugin.

JShrink is a php class that minifies javascript so that it can be delivered to the client quicker. Check https://github.com/tedious/JShrink for more info.

Works for sure with: WordPress 4.0+, PHP 5.4+.

Just install and activate the plugin, and it will seamlessly minify and combine javascript in the footer. No other actions required from your side.

Why would I use it?

It will help you to reduce number of scripts on your page and hence reduce number of http requests to your server.

When does it make sense?

If you have 3 js files enqueued in your footer – you definitely don’t need this plugin. If you there are like 20 of them – then probably you do.

What gets minified?

Scripts from the current theme, wp-includes & plugins.

Why only footer scripts?

To encourage people put their javascript in the footer.

Does it minify css?

No. Initially it was a small plugin for personal usage in conjunction with wp-less. Consider using LESS or SCSS to put your css together in a single file or use any other css minifier.

Does it uglify my javascript?

No. Only minifies and combines into a single file.
