This rules triggers when PageSpeed Insights detects that the size of one of your resources could
be reduced through minification.
Overview
Minification refers to the process of removing unnecessary or redundant data without affecting how
the resource is processed by the browser - e.g. code comments and formatting, removing unused code,
using shorter variable and function names, and so on.
To minify JavaScript, try UglifyJS. The Closure Compiler
is also very effective. You can create a build process that uses these tools to minify and rename the
development files and save them to a production directory.
Alternatively, the PageSpeed Module,
integrates with an Apache or Nginx web server to automatically optimize your site, including resource minification.
