Summary	0000457: Automatic CSS / JS Compression

Revision	2010-04-08 23:57:37 by Dmitry
Description	The elegant and simple implementation (doesn't exist yet) of solving problems with large javascript, css files being sent on every page load. Instead of <script type="text/javascript" src="<inp2:m_TemplatesBase/>js/script.js"></script> we should use <script type="text/javascript" src="<inp2:m_Script file="js/script.js"/>"></script> Tag Script would: 1. get compressed version of given file based on current theme (compressed versions could be stored under "/system/cache") 2. if given file was changed after compressed file was created, then create compressed file with file modification time in it's name and return url to compressed file 3. if given file wasn't changed after compressed file was created, then return url to compressed file There would not be any additional calls to index.php to load every compressed javascript, because of tag implementation is being used. What ever compression is made or not could be determined by new configuration variable. Compression could be turned off automatically, when debug mode is turned on for example. What compressor to use would be determined based on given file extension. What compressor engine to use will be determined in later development stages of this feature (command-line, php, java etc.). NOTE: We should be able to process multiple JS files (and probably CSS) in a single minimized version. Let's say I want something like this <script type="text/javascript" src="<inp2:m_Script file="js/script.js\|js/another_jq.js"/>"></script> I did see it a few times like this - can't remember the software / website, but will find this and put examples here.
