enderMinify() (UglifyJS)

var fs = require('fs')
var em = require('ender-minify')
var options = {} // no options for UglifyJS at the moment

fs.readFile('source.js', 'utf-8', function (err, source) {
  if (err) throw err

  em('uglify', source, options, function (err, minifiedSource) {
    if (err) throw err

    fs.writeFile('source.min.js', minifiedSource, 'utf-8')
  })
})

enderMinify() (Closure Compiler)

var fs = require('fs')
var em = require('ender-minify')
var options = {
  level: 'simple',                 // can be 'whitespace', 'simple' or 'advanced'
  externs: [ 'foo.js', 'bar.js' ]  // passed as --externs
}

fs.readFile('source.js', 'utf-8', function (err, source) {
  if (err) throw err

  em('closure', source, options, function (err, minifiedSource) {
    if (err) throw err

    fs.writeFile('source.min.js', minifiedSource, 'utf-8')

enderMinify.minifiers

A list of minifiers available as an array.

enderMinify.closureLevels

An object with mappings of the Closure Compiler compression levels, from nice-key to verbose-Closure-key.

i.e.:

{
    whitespace : 'WHITESPACE_ONLY'
  , simple     : 'SIMPLE_OPTIMIZATIONS'
  , advanced   : 'ADVANCED_OPTIMIZATIONS'
}

enderMinify.closureJar

The absolute path name to the closure.jar file used to run Closure Compiler within this package. Useful if you wanted to call it directly.
