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)
  ...
