Problem

Javascript files are too large because they are not optimized
Users & your bandwidth is wasted for useless data
local javascript optimization requires tons of programs / libaries / knowledge

Solution

Google Closure Compiler size reduction (10-97% size reduction) in the cloud
optmizes all javascript files from a given folder

Usage

Compiles a single javascript file or a whole folder in the cloud.

Usage: php compiler.php /javascripts [options] php compiler.php /javascripts/myfile.js [options]

Options are: -q, --quiet no output -p, --pretend no changes are made -r, --recursive execute the action on all subdirectories -w, --supress_warnings don't show compilation warnings -l, --compilation_level compilation level WHITESPACE_ONLY SIMPLE_OPTIMIZATIONS (default) ADVANCED_OPTIMIZATIONS -c, --combine if folder is given js files are combined in all.min.js -h, --help show this

Protection

Any file that returns a failure code, is larger than before, or is empty will not be saved.

Example

php compiler.php /javascripts
  compiling /javascripts/applications.js
  2887 -> 132 (102 gzip)                   = 4% (3% gzip)

  compiling /javascripts/social/file.js
  3136 -> 282 (240 gzip)                   = 9% (7% gzip)

  compiling /javascripts/social/app.js
  5045 -> 4 (3 gzip)                       = 0% (0% gzip)
  ...
