Merge + Minify + Refresh

Descrição

This plugin merges/concatenates Cascading Style Sheets & Javascript files into groups. It then minifies the generated files using Minify (for CSS) and Google Closure (for JS – fallback to Minify when not available). Minification is done via WP-Cron so that it doesn’t slow down the website. When JS or CSS changes files are re-processed. No need to empty cache!

Inspired by MinQueue and Dependency Minification plugins.

Minification by Minify and Google Closure

In order to ensure fast loading times its recommended to set long expiry dates for CSS and JS as well as make sure gzip or deflate is on.

Version 1.10 added should_mmr filter which allows developers to disable MMR when needed. You could use this to disable MMR for certain WordPress roles or with some Page Builders. Three new plugins have been created that utilise this:
Merge + Minify + Refresh Check DIVI, Merge + Minify + Refresh Check Visual Composer and Merge + Minify + Refresh Check Beaver Builder. Please install these when required.

Version 1.6 added support for HTTP2 Server Push to further speed up your requests (thanks to Daniel Aleksandersen).

Version 1.6.9 added the ability to specify the cache directory. Set MMR_CACHE_DIR & MMR_CACHE_URL constants in wp-config.php. MMR_CACHE_DIR must be full server path and MMR_CACHE_URL must be absolute URL for this to work correctly (thanks to Daniel Aleksandersen).

Version 1.6.11 added the ability to specify seperate cache urls for javascript and CSS. Use MMR_JS_CACHE_URL & MMR_CSS_CACHE_URL to replace MMR_CACHE_URL.

Version 1.7.0 added the ability to generate .css.gz & .js.gz files. Your webserver may need to be configured to use these files. Here is how to use these files in Apache:

#Serve gzip compressed CSS files if they exist and the client accepts gzip.
RewriteCond %{HTTP:Accept-encoding} gzip
RewriteCond %{REQUEST_FILENAME}\.gz -s
RewriteRule ^(.*)\.css $1\.css\.gz [QSA]

#Serve gzip compressed JS files if they exist and the client accepts gzip.
RewriteCond %{HTTP:Accept-encoding} gzip
RewriteCond %{REQUEST_FILENAME}\.gz -s
RewriteRule ^(.*)\.js $1\.js\.gz [QSA]

#Serve correct content types, and prevent mod_deflate double gzip.
RewriteRule \.css\.gz$ - [T=text/css,E=no-gzip:1,E=is_gzip:1]
RewriteRule \.js\.gz$ - [T=text/javascript,E=no-gzip:1,E=is_gzip:1]
Header set Content-Encoding "gzip" env=is_gzip

Version 1.8.8 added a “merge_minify_refresh_done” hook that fires when JS or CSS has changed.

Version 1.11 added two new constants:
MMR_USE_CLOSURE – allows Google Closure Javascript minification to be disabled.
MMR_REMOVE_EXPIRED – disables removing expired files.

Note Installing this plugin on a server with the eAccellerator module installed has the potential to break as Minify uses anonymous functions which return NULL. View eAccellerator Issue Thread

Compared to FVM and Autoptimize, this plugin is really simple. You set up the plugin thanks to one page. And you can check the cached page on the very same page where you change the settings. The developer really focused on JS and CSS. There is no adhoc stuff like lazy loading, removing HTML comments, removing querystrings. I am happy about it because I discovered that autoptimize had a bad behavior with stripping querystrings. It messed up my wordpress structure. Conversely, This plugin MMR sticks to what we expect from it => optimize JS and CSS. I really like when a developer just focus on a very well-defined goal rather than babbling in different wordpress area. GOOD JOB

My GTMetrix score went from F to A, but then it was so slow executing that Divi Builder would not load. I have max_execution_time settings of 120. As soon as I deactivated the plugin, Divi loaded fast again. It does a good job minifying and concatenating JS, CSS and HTML, but please look into this with Divi, as I cannot fault Divi on this. Please get back to me, as I prefer your plugin over the rest, if you can solve this Divi issue.

Result on google PageSpeed Insights with same configuration Merge + Minify + Refresh plugin = 71-80 (mobile) and 98 (Desktop) with 35 request with no conflict Autoptimize plugin = 65-78 (mobile) and 91 (desktop) with 26 request with no conflict Well done.

Works great, minimal settings, no ads/bloat, stays out of the way. Please keep up the good work.

I just tested this on localhost not on a production site but its seems like it works like a charm and does its jobs really well. So far i can't see any script or style conflicts, so i guess on a good codebase (probably when all scripts and styles are integrated via WordPress enqueue API) this plugin just works. Im gonna test the impact on a live website but i think this is gonna be quite relevant.
