Maximum Call Stack size exceeded: My mishap with nodejs and MongoDB

Working with nodejs is always an adventure and mix MongoDB with it, and it becomes very interesting for a nodejs enthusiast like me.

While working on a pet project involving Native MongoDb driver and nodejs I encountered a weird problem.

RangeError: Maximum call stack size exceeded
As usual my first thought was to Google out what I was facing and googling it out led me to the following to links.
Also In some posts in MongoDB’s forum I saw that peoples said saving in `process.nextTick` or wrapping the call function in `parseInt` will also fix the problem, but it most certainly didn't work for me.So I started digging in on my own and soon enough found the reason.

If you’re trying to save a document and saving process somehow exited with an RangeError: Maximum call stack size exceeded exception, it’s related to what you want to save in the database. I had this problem also, and when I checked my object, I found that the problem is related to the big DOM Object that I included in the object, and when I removed that, the object saved in MongoDB correctly.

My piece of buggy code:

  seq: nextSeq,
  profileIdentity: profileIdentity,
  sectionData: secData, //the buggy part 
  findDateTime: new Date()
 The problem occurred in `secData` array. In the second item of that array I had a big DOM Object and after removing that object from array (and of course, doing that job in a different way), problem solved.

VR For Everyone: When you get to play and teach WebVR

This blog is pretty late to the party. But recently I have been having quite some fun with tinkering with WebVR. What started for me initially with mozVR and then standardized into WebVR changed completely when aframe came into the picture!

So let me back off a little bit. WebVR started as an entry pint of browsers coming into play where we could get VR content from directly browser. Just imagine writing a game or environment in javascript,html as a webpage and use your phone/occulus rift and you get transported in virtual reality! How cool is that? No need to use other software, no platform restrictions. As long as you have a browser and an internet connection, you are good to go! However that didn't pan out so well due to how you create them. The only way to properly utilize it was to use WebGL and libraries like three.js. All of this changed when Mozilla released aframe on 16th December 2015. From the aframe team

All Hands 2016: MozLondon, A recount

I recently had the opportunity to take part in Mozilla All Hands 2016 (a.k.a #MozLondon). Mozilla All hands. All Hands are bi-yearly events of Mozilla where all the paid staff from different teams around the globe meet with each other along with a handful of invited volunteers to disscuss about future projects and get some work done! This year it was in London and just immediately before Brexit (I actually didn't even know about it before I went there). It was a work week, so essentially the event spanned from Monday to Friday. I arrived at LHR on Monday morning, and then there was the awesome Heathrow Express which took me to Paddington, just a 7 mins walk away from Hilton Metropole where I was staying with a bunch of other people. The event started with all of us having an evening orientation familiarizing us with rules and regulations along with Code of Conduct(that turned out to be really important later on...).  Tuesday started with a Planery. Which you can see if you are lo…
