Can I use GZIP compression on files that have been minified by Gulp or Grunt? I wonder if there is possibility that I have problems regarding this. Or if I would have an even faster upload on the browser side.

linux grunt gulp gulpjs gzip

Yes, it’s a good idea to minify your files .js and .css and then compress them using gzip.

I did a simple test with the jQuery. I downloaded the non-minified jQuery and the minified:

-rw-rw-r-- 1 user group 258648 Mar 17 23:32 jquery-2.2.2.js
-rw-rw-r-- 1 user group  85656 Mar 17 23:32 jquery-2.2.2.min.js

Notice that the non-minified jQuery has 258 Kb and the minificado 85 Kb.

And after that I compressed the two files using the command gzip -9 (-9 represents the slowest and most effective compression):

-rw-rw-r-- 1 user group  76515 Mar 17 23:32 jquery-2.2.2.js.gz
-rw-rw-r-- 1 user group  29763 Mar 17 23:32 jquery-2.2.2.min.js.gz

The jQuery file only compressed possesses 76 Kb, while the jQuery minified and compressed possesses 29 Kb.

And since you are already using the Grunt, take a look at the grunt-contrib-compress to automate file compression.
