Create chained methods in node.js?

Question

Is it possible to create chained methods that are asynchronous like this in node.js

File.create(\'file.jpg\').rename(\'renamed.jpg\').append(\'Hello World\')
         


        

Answer 1

Sure, like any JavaScript, you just return an object that has that method.

One possible layout (among many).

var File = new (function() 
{ 
  this.create = function(str) 
  { 
    return this; 
  } 
  this.rename = function(str) 
  { 
    return this; 
  } 
})();
