Re: Best practices for using CSS resource references
Hi Alec, I'm using this maven plugin on production releases: http://alchim.sourceforge.net/yuicompressor-maven-plugin/ that compress the CSS and the JS before packaging it into the WAR.

Re: Best practices for using CSS resource references
3 responses in one day, awesome! Serban and Jordi, our app allows users to upload custom CSS so compile-time solutions will not work for us here. Martin, if I understood you correctly there is no special support, such as removing comments, in Wicket for CSS resources, right? If CompressedResourceReference is removed in 1.5 what should be used instead? (In migration guide https://cwiki.apache.org/WICKET/migration-to-wicket-15.html it says See above) Thanks, Alec On Tue, Feb 7, 2012 at 1:19 AM, Jordi Deu-Pons jo...@jordeu.net wrote: Hi Alec, I'm using this maven plugin on production releases: http://alchim.sourceforge.net/yuicompressor-maven-plugin/ that compress the CSS and the JS before packaging it into the WAR.

You can use YUI compressor or Google Compiler. CompressedResRef is removed because the web container does this for you. Check your web container docs.

Usually servers not only support that feature but also are more flexible so there's no need for a redundant functionality that does not belong to a web framework but to the server itself.

Re: Best practices for using CSS resource references
Hi Alec, With wro4j you can do the minification at runtime also by using the processors like: http://code.google.com/p/wro4j/wiki/ReusingProcessors you get to work with Reader and Writer. You could apply the processor after the resource has been uploaded or even when requested(though probably it's more efficient to do the first). -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Best-practices-for-using-CSS-resource-references-tp4362796p4365408.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Best practices for using CSS resource references
Martin, removing CompressResRef in 1.5 makes perfect sense. Thanks for pointing me to CssCompressor and JavaScriptCompressor. Serban, thanks for a good link. I can see how I can use wro4j Reader/Writer code to implement CssCompressor Martin pointed out. Thanks again, guys!

Re: Best practices for using CSS resource references
Hi Alec, Not really a direct reply to your question rather another. Wro4j project is more powerful(configurable) when it comes to grouping and minification css/jss, and I think maybe the WroFilter can easily be turned into a Wicket Resource, for a tighter wicket integration, I'm wondering if this has not already been done by someone. Also for JS references a parser for wro.xml that returns the contained js entries in a group to distinguish between wicket development and deployment versions could be done. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Best-practices-for-using-CSS-resource-references-tp4362796p4363970.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
