Minify static JS/CSS in Magento 2

Overview

There are some troubles with JS/CSS minification in Magento 2 (one, two, three, ...).

This extension just minifies all JS and CSS files in ./pub/static/** folder using matthiasmullie/minify module. All minified files stay on the places of the original files. All original files are backed up with extension *.not_minified.

Sample Magento 2 application with default Luma theme has 60/100 points on Google PageSpeed Insights and 2.4 MB size for it's home page before minification and 69/100 points and 1.5 MB after minification (details).

CAUTION: JS and CSS files in ./pub/static/** folder are links to the files in ./vendor/** folder, these files will be minified in result. Use this module in case you can re-deploy original files.

Installation

$ composer require flancer32/mage2_ext_minify
$ ./bin/magento setup:upgrade

Usage

Perform compilation of the static content before minification:

$ ./bin/magento setup:static-content:deploy

or switch to production mode:

$ ./bin/magento deploy:mode:set production

then run minification:

$ ./bin/magento fl32:minify:make
...
File '/var/www/vhosts/sample_mage2_module/work/pub/static/frontend/Magento/luma/en_US/tiny_mce/themes/simple/skins/o2k7/ui.css' is minified.
Total 2266 JS and 225 CSS files are found in './pub/static/' folder.
Total 2266 JS and 225 CSS files are minified.
Don't forget reset permissions for the files.

To revert minification:

$ ./bin/magento fl32:minify:revert
...
File '/var/www/vhosts/sample_mage2_module/work/pub/static/frontend/Magento/luma/en_US/tiny_mce/themes/simple/skins/o2k7/ui.css' is reverted.
Total 2266 JS and 225 CSS files are found in './pub/static/' folder.
Total 2266 JS and 225 CSS files are reverted.
Don't forget reset permissions for the files.
