Introduction

In this tutorial we learn how to install yuicompressor on CentOS 8.

What is yuicompressor

The YUI Compressor is a JavaScript compressor which, in addition to removing comments and white-spaces, obfuscates local variables using the smallest possible variable name. This obfuscation is safe, even when using constructs such as ’eval’ or ‘with’ (although the compression is not optimal in those cases) Compared to jsmin, the average savings is around 20%. The YUI Compressor is also able to safely compress CSS files. The decision on which compressor is being used is made on the file extension (js or css).
