nodeJs huge array processing throws RangeError: Maximum call stack size exceeded

Question

This is part of code to proceed big number of entries ( originally its works with file system and make some operations with files) . Is there any nice way to bypass the limitat

Answer 1

The problem is that you are making to many function calls. Setting the stack-size to a higher value will only increase the number of items you can handle, not solve the actual problem.

You are calling the next iteration straight from your function, which makes it a recursive function. It's a bit hard to spot since it's going thru async.

This code should work:

var tifPreview = function (item, callback) {
  console.log(item);

  // defer the callback
  setImmediate(callback);
}
