Make Node async operations sync

Sometimes methods on a node package do async operations and have no sync variants. Using 'deasync' we can make this a breeze and keeping your code clean.

Usage:

(replace yourAsyncMethod with your function)

console.log('starting');

sync.do(function(){
 yourAsyncMethod(function(){
 console.log('operation done');
 sync.done();
 });
});

console.log('end');

Definition:

var sync = {
 _deasync: require('deasync'),
 _done: false,
 do: function(callback, sleep) {
 this._done = false;
 callback();
 while ( ! this._done) {
 this._deasync.sleep(sleep ? sleep : 100);
 }
 },
 done: function() {
 this._done = true;
 }
}
