Question

I need to run a function on my node.js server, that completes the same task every 15 minutes.
I Used for that setInterval as in example number 3 here – http://tinyurl.com/c2jj7dl.
So, I got to something like this:

exports.start = function (list, callback){
    setInterval(stuffTop.loadstuff, 900000, list, function (parsedList) {

                // CODE STUFF HERE


                // THEN THE CALLBACK.
        callback(parsedDynamicList);

    });

}

Actually this stuff work, but the function gets completed for the first time – only after 900000MS.
Is there an option to make to function complete (in the first round) – straight when called ? Thanks.

Use a function which recursivly calls itself:

foo = function(){
  doStuff()
  setTimeout(foo,900000)
}

In your case It would look like this:

exports.start = function (list, callback){
  var foo = function () {
    stuffTop.loadstuff(list, function(parsedList) {
      //CODE STUFF HERE
      //THEN THE CALLBACK
      callback(parsedDynamicList);
      setTimeout(foo,900000);
    });
  }
  foo();
}
