YA ComonJS to browser packer tool, well-suited for tiny widgets by small overhead and big app by module replacement, node-environment emulations and multi-exports.

what in a box?

  • .js - just put it to bundle as is
  • .json - wrap in module.exports as node do it on require('file.json')
  • .coffee - compile to JavaScript
  • .eco - precompile to JavaScript function
  • .jade - precompile it in client-mode way
  • .jsx - compile React '.jsx' to JavaScript
  • .csbx - compile '.jsx' on Coffee with backticks to JavaScript (yes, we do it)

what about my custom template engine?

This possibility almost exists - clinch from 0.2.5 have API for third party processors, but template engine must support template-to-function precompilation.

More info and example - below at description of method registerProcessor()

For additional example - see using Handelbars - yap, now Hadlebars supported as add-on.

More about .jade

Compiled client-mode template may be used wia require(). More information at './test', also examples was placed in wiki jade template engine. In browser should be pre-loaded Jade's runtime.js.

More about React (.jsx, .csbx)

Created by clinch file can be requested via the require (), as is done in the tests. For use in the browser requires the connect of the React, its runtime-transfom tool not needed, everything will be prepared and packed.

React was added to the kernel and will be mandatory to be supported, it's a phenomenal tool for writing maintainable code.

Unfortunately while combining the best of two worlds - CoffeeScrip and jsx by React implemented "in place" - used trick with the backticks, which allow you to insert in CoffeScript js code that are not parsed them . This is the reason for such an extension of selected files - "Coffee Script with Backticks eXt" - .csb

As soon as the normal method to combine both of these tools - I 'll do it ASAP, most likely with the file extension is .csx


npm install clinch


#!/usr/bin/env coffee
Clinch = require 'clinch'
packer = new Clinch runtime : on
pack_config = 
  package_name : 'my_package'
  bundle : 
    main : "#{__dirname}/hello_world"
packer.buildPackage pack_config, (err, data) ->
  if err
    console.log 'Builder, err: ', err
    console.log 'Builder, data: \n', data

Content of ./hellow_world

This is 'Hello World!' example
module.exports = 
  hello_world : -> 'Hello World!'

Now data contain something like this

(function() {
  'use strict';

  var dependencies, sources, require, modules_cache = {};
  dependencies = {};

  sources = {
"JPGt0": function(exports, module, require) {
// /Users/meettya/github/clinch/example/hello_world/ 
This is 'Hello World!' example

module.exports = {
  hello_world: function() {
    return 'Hello World!';

if(this.clinch_runtime_v2 == null) {
  throw Error("Resolve clinch runtime library version |2| first!");

require =, dependencies, sources, modules_cache);

/* bundle export */
this.my_package = {
  main : require("JPGt0")

And in browser function may be accessed in this way

hello_world = my_package.main.hello_world


clinch have minimalistic API


packer = new Clinch clinch_options

clinch_options - Clinch settings


packer.buildPackage package_config, cb
# or old form, will be deprecated in new version
packer.buildPackage package_name, package_config, cb

package_name - root bundle package name (like $ for jQuery), remember about name collisions, may be omitted. Will be deprecated in new versions, use package_config.package_name

package_config - package settings

cb - standard callback, all in clinch are async


packer.registerProcessor file_extention, fn

This method allow to register any file content processor, which will be used to process files with file_extention.

file_extention - file extension to proceed

fn - processor function


# add .econ processor
packer.registerProcessor '.econ', (file_content, filename, cb) ->
  content = Eco.precompile file_content
  cb null, "module.exports = #{content}"

At now clinch will be compile all required .econ files with this function.

And in module code:

template = require './template' # ./template.econ, extension may be omitted
res = template data # res now is some html-contented string



This method will force flush packer cache. As usually clinch flush cache if files changed, but for some rare cases its available to force it.


packer.getPackageFilesList package_config, cb

This method will return an Array of all files, used in package building process. May be used for custom watch implementation or in other cases



log           : off  # will add verbose output, but now not realized yet
strict        : on   # knob for 'use strict;' in bundle header
inject        : on   # if changed to 'off' - bundle will not to inject 'package_name' to global
runtime       : off  # use internal boilerplate code, or as external file
cache_modules : on   # by default all resolved by 'require' file will be cached, if you have some problem - turn cache off and notice me

this settings will be applied to jade.compile() function
jade :
  pretty : on
  self : on
  compileDebug : off

this settings will be applied to React compiler
react :
  harmony : off


May be omitted. If omitted - inject all bundle members to global OR, if `inject : off` in package settings - make all bundle members local for bundle (it may be usefully in case of widgets with self-detection)
package_name : 'bundle_pack_name'

# bundle settings
strict : on   # bundle knob for 'use strict;' in bundle header
inject : on   # if changed to 'off' - bundle will not to inject 'package_name' to global
runtime       : off  # use internal boilerplate code, or as external file
cache_modules : on   # by default all resolved by 'require' file will be cached, if you have some problem - turn cache off and notice me

At least one key must be exists
name -> code place
this keys was be exported when script loaded
bundle = 
  main   : function(){...}
  helper : function(){...}

later in code

  main = bundle.main

bundle :
  main : './src'
  helper : './src/lib/helper'

This is local for code variables, to imitate node.js environment,
or replace somthing
Important - keys will be used as variable name, so any strange things may happened
if it not old plain string, remember it!!!
environment :
  process : './node/js-process'
  console : './node_modules/console-shim'

This part replace modules with browser-spec one
replacement :
  util : './node_modules/js-util'
  lodash : -> @_  # yes, its allowed to use function instead of file (`this` will be pointed to global scoop)

this is list of modules, which is not be placed in bungle
exclude : [

This is list of modules, which we are not check for require in it
save time with huge pre-bulded libraries, like `lodash` or `jquery`
if we are decide to place it in bundle
requireless : [


See example or test dirs.

Also some examples will be available online at clinch_demo.

Also clinch will be used to browser-pack TinyData, see sources and packed lib
