In depth

A closer look at YUI Compressor GUI

Few high-level, interpreted programming languages are as well-known in the world (more precisely the IT community) as Javascript (abbreviated as JS) and Cascading Style Sheets (abbreviated as CSS).These two programming languages, along with HTML are the three core programming languages of the world wide web.YUI Compressor GUI is a simple GUI for YUI Compressor written in C#, and can be used to compress any Javascript and Cascading Style Sheets to an efficient level that works exactly as the source before it was minified.

A more beginner friendly version of the original program

Anyone who's ever written code in any of them is probably familiar with the concept that since the lines are used to regulate complex actions in web pages, the lines of code could eventually lead to an increase in file size of the overall file.Originally developed to be is a .NET port of the Yahoo! UI Library's YUI Compressor Java project, the GUI version was created for those users with minimal code writing skills that still wanted to perform basic tasks.

Minimalist UI and quick work

As expected from a program with such a simple task, the UI is kept to a minimum, while still giving you enough features to stay relevant.All you have to do to compress a JS or CSS file si browse for its location, then select whether the compression settings you wish to apply.For example, you can choose, along with the compression itself, to minify only (the file will not be obfuscated), preserve any unnecessary semicolons or even disable micro-optimizations.File conversion depends on the overall size of the lines of code, but it is generally finished in a matter of seconds.

O good addition for any website developer

YUI Compressor GUI can be used to make your website smaller and faster to load by minifying the JS and CSS code, making it an indispensable tool for any website administrator.
