Closure-compiler-service NPM

closure-compiler-service

Compile JavaScript with the Google Closure compiler service. No Java dependency.

Installation

# npm -g install closure-compiler-service

Usage

Command Line

Output is written to stdout, and can thus be redirected to a file:

$ closure-service input.js > input.min.js

Module

var ccs = require('closure-compiler-service');
var input = fs.readFileSync('input.js');

/**
 * Compile a string of JavaScript with the Closure compiler service
 *
 * @param {String|Buffer} js_code - JavaScript code to compile
 * @param {Object} [options] - API options
 * @param {Function} [callback](errs, warns, code) - defaults to console output
 */
ccs.compile(input, function(errs, warns, code) {
  // `code` is the compiled result
});

ccs.compile optionally takes an options object as the second argument (before the callback function), which are passed to the API:

ccs.compile(js_code, {
  compilation_level: 'WHITESPACE_ONLY'
}, function(errs, warns, code) {
  // ...
});

Pass an array to stipulate multiple values for the same option:

ccs.compile(js_code, {
  code_url: [url1, url2 /*, ... */]
}, function(errs, warns, code) {
  // ...
});

js_code may be null if using code_url to provide code.

Default Options

output_format     = 'json' // you won't want to change this
output_info       = ['compiled_code', 'errors', 'warnings']
compilation_level = 'SIMPLE_OPTIMIZATIONS'
