re-define

Let's re-define something ... without any configuration ... just do the magic for me.

Easy way to convert AMD and CommonJS projects to one bundle wrapped in UMD.

Why

• to get decent encapsulation, registering a bundle not a part
• to make project compatibile across node and web without effort

Features

• highly customizable: templates, transforms (like with browserify), discoverable folders
• now also resolving modules dependencies
• looking for dependencies in node_modules and bower_components
• resolving whole dependencies trees as well as single file
• resolving AMD !text plugin within cjs and amd code
• using vinyl, integration with gulp should be easy
• (WiP) detailed report, to get whole picture, display modules, dependencies and externals

Nice things

• when re-define meet external dep, automatically checks descriptor files, such as bower.json and package.json, there is also a fallback to node_modulesas well asbower_componentswhen descriptor is missing or there is nomain` defined
• when including an UMD file as a dep and your define module is anonymous, re-define will add a name for you also check internal depenencies

Limitation

• does not resolve circular dependencies
• module.export override exports when defined below exports
• resolve only static require statements

Getting Started

Install the module: npm install -g re-define

###Usage

Usage: re-define [options]

Options:
  '-t, --transform [libs]'      , 'Custom transforms stream invoked for each module'
  '-m, --main [filepath]'       , 'Main file'
  '-b, --base [dir]'            , 'CWD'
  '-d, --discoverable [dirs]'   , 'Check in folders when encouter an external dep'
  '-e, --external [json]'       , 'Exact dep locations, when discoverable is not enough'
  '-g, --globals [module#as]'   , 'Global reference to external libs'
  '-w, --wrapper [type]'        , 'Wrapper type report, default: umd'
  '-n, --name [module]'         , 'Module name'
  '-r, --returns [module]'      , 'What module returns'
  '-s, --skip [module]'         , 'Exclude external module from result bundle'
  '-e, --exclude-deps [deps]'   , 'Exclude deps'

Example usage

check example folder and appropriate build files

Debbuging

To run re-define in debug mode is fairly easy, just run re-define with appropriate category like below

//all
DEBUG=re-define:* 

//specific:
re-define:transform:* 
re-define:converter
re-define:bin

###Config

  { cwd          : '.'
  , name         : 'module_name'
  , wrapper      : 'umd'
  , returns      : ''
  , excludeDepRef  : ['\.css$', 'require', 'modules', 'exports']
  , globals      : [] //external module_name#global_ref
  , external     : {} //{"jquery": "location"} or {"..": "{path: "...", cwd: "..."}
  , discoverable : ['node_modules', 'bower_component']
  , descriptors  : ['package.json', 'bower.json']
  , plugins      : [{extension: '.html', pattern : '^(text\/?)*!'}]
  , escape       : function (val) { return val.replace(/\.\/|\!|\.|\/|\\|-/g, '_') }
  }

####Custom transform

var through = require('through2')

module.exports = function(config) {

  //config instance

  return through.obj(function(file, enc, next) {
    /* 
    //inside of file you can find following properties
    {
      "cwd": "lib",
      "base": "lib",
      "path": "./lib/main.js",
      "ext": ".js",
      "type": "require",
      "ast" : ...
      "contents" : ...
      "deps": [
        {
          "path": "jquery",
          "require": "jquery"
        }
        ...
      ]
    */

    //your own spells

    this.push(file)
    next()
  })
}
