What do you use to minimize and compress JavaScrip

Question

What do you use to minimize and compress JavaScript libraries?

Answer 1

I don't minimize JavaScript at all: gzip compression is good enough for me and has the additional benefit that error messages will still be useful.

Answer 2

https://jawr.dev.java.net/ is excellent for minification and versioning

Answer 3

I have tried YUI compressor before, but it gives me error message.

I suggest using JSMIN to minify your javascript:

Answer 4

I use perl's JavaScript::Minifier. It works pretty well and you can e.g. replace some phrases using perl.

Answer 5

Dean Edward's packer achieves some pretty good compression ratios. It has command line implementations which allows it to be used in a continuous integration process.

Answer 6

I use YUI Compressor. Seems to get the job done well!
