I'm running a node.js app and have a process that runs every 500ms. There's a lot of logic that's being done and at times, we found it could run over 500ms - this caused problems when using a setInterval.
We redesigned this to use setTimeout with a callback such as this:
var start = function() {
self.performProcesses(function() {
setTimeout(function() {
start();
}, 500);
});
}
start();
The problem is sometimes this stops, meaning somewhere along the road a callback from performProcesses
is not being hit. There are thousands of lines of code that reach multiple objects and files.
Would anyone recommend a good way to try to debug this and isolate where the break may be?
Thanks!
When I program in JavaScript I use Aptana . It is part of a collection called Appcelerator, which is pretty much Eclipse. Aptana let's you develop and debug in JavaScript, so you can StepInto, StepOver, and whatever..
Have you tried web-inspector ?
You can also try Paul Irish anim shim at loop controlling. If you call requestAnimFrame
after self.performProcess
, it will be called at interval of 500ms.
var requestAnimFrame = function (callback) { setTimeout(callback, 500); };
(function animloop () {
self.performProcesses();
requestAnimFrame(animloop);
})();
