Require to global scope in node.js

Question

In my node.js script I have:

var wu = require('./wu-0.1.8.js');

just to play with wu.

If it was in browser, then I could just use wu everywhere e.g.

wu([1,2,3]).map( function(n){ return n*n; } );

Hovever in node.js I have to write:

wu.wu([1,2,3]).map( function(n){ return n*n; } );

Is it possible to append wu to global scope so that I dont have to type wu.wu all the time?

var wu = require('./wu-0.1.8.js').wu;

edit (response to comments):

If you need to use other methods in require('./wu-0.1.8.js'), you can always do this...

var wuModule = require('./wu-0.1.8.js'); 
var wu = wuModule.wu;

// Now you can do 

wu([1,2,3]).map( function(n){ return n*n; } );
wuModule.someOtherWuMethod(...);

Sir Bohumil Over a year ago

what if there were more exported functions that I wanted to access, say 100 ?

you mean like, wu.foo(), wu.bar(), in addition to wu.wu()?

Then my answer would not work... but it wouldn't make sense for there to be a wu.wu method at all if it's a "master" function (like $ is in jQuery). The designer(s) of wu should have exported the wu function and added wu.foo and wu.bar as methods (properties of wu).

Well, I suggest you not to do so but you can iterate through the wu object properties and attach them to global object:

var _wu = require('./wu-0.1.8.js');
var key;
for (key in _wu) {
  if (_wu.hasOwnProperty(key)) {
    global[key] = _wu[key];
  }
}
