windowify

Allows regular JavaScript files to expose global variables and functions when bundled with Browserify.
We can find old code written this way:

• jquery.js:

```javascript function jQuery(selector) {

/* ... */

} ```

• test.js:

```javascript var $element = jQuery('#some-element'); ```
When we bundle the file with the jQuery definition, we loose the global reference to jQuery because it is no longer declared in the top level scope:

browserify jquery.js -o jquery.bundled.js

• jquery.bundled.js:

```javascript / PREAMBLE / })({

1: [
  function(require, module, exports) {
    // jQuery is not global now!
    function jQuery(selector) {
      /* ... */
    }
  }, {}
]

}, {}, 1); ```
This module transforms those files exposing those variables to window:

browserify jquery.js -t windowify -o jquery.bundled.js

• jquery.bundled.js:

```javascript / PREAMBLE / })({

1: [
  function(require, module, exports) {
    (function(window) {
    function jQuery(selector) {
      /* ... */
    }
    // jQuery is global again!
    window.jQuery = exports.jQuery = jQuery;
    }).call(window, window);
  }, {}
]

}, {}, 1); ```
It also sets window as the context of the code (for code setting global variables to this).

Installation

npm install windowify --save-dev

Usage

Like any other browserify transform, you can use in 3 ways:

• Adding the configuration to the package.json:

{
  "browserify": {
    "transform": [
      ["windowify", {"files": "**/jquery.js", "debug": true}]
    ]
  }
}

• Command-line usage:

browserify entry-point.js -t [ windowify **/jquery.js --debug ] -o entry-point.bundle.js

• Programmatic usage:

var b = browserify('entry-point.js');
b.transform('windowify', {files: '**/jquery.js', debug: true}]);
