Merge + Minify + Refresh: Force Async Scripts

This little plugin has one job: make all merged scripts produced by the Merge + Minify + Refresh plugin load asynchronously.

Get the plugin on GitHub.

Installation Instructions

  1. Copy the merge-minify-refresh-async.php file to your wp-content/plugins/ directory (or compress to a zip file and upload in the WordPress backend “Plugins > Add New”
  2. Activate
  3. That’s it. All the merged scripts will be loaded with the async attribute.

Potential Issues

Note that if you have plugins or other code that adds inline Javascript, it probably will break if it’s depending on jQuery (for example) to be loaded and active already.

One workaround is to exclude /wp-includes/js/jquery/jquery.js from the Merge + Minify + Refresh cache, but you may have to exclude other scripts as well.
