Ticket #8794 (closed enhancement: invalid)
Use Closure Compiler for minification
|Reported by:||paul.irish||Owned by:|
Just watched a presentation from Closure Compiler's lead developer. He was asked about jQuery and the fact that it had switched to Uglify.
He was aware of the switch and found an issue with CC that led to larger filesize. jQuery's use of returning the closure that defined jquery and using that for the global definition... (i think) was what led to some longer local names than necessary.
Alan said the current release of CC should compile 2-3% smaller than uglify.
As an unrelated side note: CC targets gzip size, so when you see leftover optimizations not touched, it is likely they do not effect the gzipped size in the right direction. (Like using !0 in place of true)
