Closure Auto Compiler
The Closure Auto Compiler utilizes Google's Closure Compiler to automatically minify Javascript files as they are updated on your file system.
Currently, once executed via the command line the auto-compiler will poll a given directory for any *.js files that have been recently updated. Once it finds a candidate it performs the minification, resulting in a newly updated *.min.js file.
Requirements
- Linux or Mac OSX
- Google's Closure Compiler
Installation
Download the latest Closure Compiler from the Google Code page, and place the
compiler.jar file somewhere on your computer (typically /usr/local/lib
or the like).
Checkout the js-auto-compiler script somewhere in your $PATH (make it executable
via chmod +x).
Create a configuration file called /etc/default/closure with your desired polling
frequency and the path to the compiler.jar file. Example
/etc/default/closure
CLOSURE_COMPILER="/usr/local/lib/compiler.jar"
FREQUENCY=5 # poll every 5 seconds
Usage
Run the following command in a terminal to start auto-compiling:
user@hostname:~$ js-auto-compiler /path/to/js/
Scanning directory: /path/to/js ...
minifying: somefile.js => somefile.min.js
