native-minify

Introduction

native-minify is a JS minify tool which removes comments and unnecessary whitespace from JavaScript files.

It allow you to compress JavaScript typically reducing file-size by half.

Please be careful with your original files this minify-cation is one-way process only.

What native-minify does?

• It omits some characters in JavaScript files.
• It replaces all control characters (including tab) with spaces.
• It replaces comments in the "// ..." and "/* ... */" form with whitespace.
• All spaces and newlines when acceptable are replaced with a single space
• It is careful when omitting newlines, because their are sometimes treated as semicolons.

What native-minify doesn't do?

• It doesn't modify any other characters in your code.
• It doesn't obfuscate your code.
• If your code looks like this it wont work just yet:

if ( _lineCount === _linePoolLength ) {
 
    var line = new THREE.RenderableLine();
    _linePool.push( line );
    _linePoolLength ++;
    _linePoolLength++;
    _lineCount ++
    return line;
 
}

• If your code in worst case looks like this it will work:

var crazyCode = {
    test01: 1,
    test02: 2,
    test03: 3
}
crazyCode.test04 = 4;

How to use

var JSMin = require('native-minify');
JSMin.minifyFile([  '/full_path_to_file_input/backbone.js',
                    '/full_path_to_file_input/three.js'], 
                    '/full_path_to_file_output/compacted.min.js', 
                    function(results){
                        console.log(results);
                    }
);

or

var JSMin = require('native-minify');
JSMin.minifyFile(['/full_path_to_file_input/backbone.js'], '/full_path_to_file_output/compacted.min.js');

Character Set

native-minify requires that the character set encoding of the input is ASCII or UTF-8.

Simple Benchmark

This is simple benchmark on minifying 100 underscore.js files

Support and Bugs

If you are having trouble, have found a bug, or want to contribute don't be shy.

I did a very little testing so if your JS code is valid but after minimization doesn't work please open a bug ticket so we can fix that!
