Question

I’m looking to implement UglifyJS into my Ant build process to replace YUI Compressor. What are the basic steps to get started?

Answer 1

After having installed uglifyjs with -g option:

npm install uglify-js -g

Use ant like that:

<exec dir="${build_dir}" executable="uglifyjs.cmd">
  <arg line="-o jquery.min.js --unsafe -nc jquery.src.js"/>
</exec>

On Windows you use uglifyjs.cmd, and uglifyjs on linux. You can define a conditional property if you want to keep the build.xml cross-platform.
