Node.JS & HTML5
The future of web development
Part of my role is to evaluate new technologies, and see if they can fit into our stack.
I had the opportunity to evaluate and use Node.JS for the last year or so...
.. and in every presentations I do, people is always desperate to know: What is node.js?
Thursday, February 2, 2012
What is Node.JS ?
I don’t want to focus on the WHAT!
Thursday, February 2, 2012
What is Node.JS ?
Let’s better focus on the why and how!
Thursday, February 2, 2012
Node.JS is a program that can do anything Apache can do,
and much more...
To give you just a little bit of context, for those who haven’t hear about node, let’s just say that ...
... and much more faster ...

Why Node.JS ?
Why are some many developers excited about it?
Why you should pay attention to it?

In the context of HTML5, we can see some very interesting trends.

... and Node.JS is at the top of that chart as well.
That’s an interesting metric.
Are they related somehow?
Thursday, February 2, 2012
... but, why ?
but of course, that doesn’t explains why it is so popular these days.
The way I see it, the real reason behind this popularity is ...
Thursday, February 2, 2012
... because it is JavaScript !
... javascript is the driving force behind Node.JS

https://github.com/languages
Javascript is, by far, the most used languages now days...
Questions for the audience?
Thursday, February 2, 2012
How does this helps at the server side ?
but if Javascript is the language we use at the browser ....
I want to explain this through an example...

Nice code !!!
... but, what you can tell me about this piece of code?
Where is this code meant to be executed? Can you tell? No, you
can’t.
Thursday, February 2, 2012
Is this SSJS ?
Well, it is just Javascript...
It doesn’t matter where it runs if we have a runtime for it...
Thursday, February 2, 2012
Creating code that can run in different envs is not new...
... but crossing the bridge between the server and the client is definitely new
Thursday, February 2, 2012
Why does this matters ?
Why is this important?
and for whom?
Thursday, February 2, 2012
It matters a lot, especially for developers.
... the twitter example ...
- context switch for devs is bad for business
- progressive enhancement and graceful degradation are now possible...
Thursday, February 2, 2012
Javascript everywhere...
Let’s talk more about the benefits of using the same language everywhere...
... there is a new vector that can affect our products drastically: variable connection speed (past vs future)
How to personalize the way our product runs:- per user- per request- per connection speed
... example of the kind of product we want to build...

MojitoJavascript Application Framework
Mojito is an app framework for web developers
Mojito is an important part of this new infrastructure
... and it will be open sourced in few weeks.
Thursday, February 2, 2012
Module vs Widget
Mojito is trying to change that
There are many MVC application frameworks out there...
- Backbone.JS- Symphony... they all have the same problem...
Thursday, February 2, 2012
Having multiple Javascript runtimes is what you can do... because JS is everywhere...
Examples:
- Y! connected TV - Netflix

Node.JS Performance
Since Node.JS is a new technology, many people are concern about performance, stability, etc...
Imagine yourself talking to your boss about a new technology....
... the story about SD Perf ...
Thursday, February 2, 2012
we did a different kind of pitch...
Thursday, February 2, 2012
comparing an actual production quality component... apple-to-apple
Thursday, February 2, 2012
... and the result was...
Thursday, February 2, 2012
Thursday, February 2, 2012
Is that even possible?
How? how does it do it?
Thursday, February 2, 2012
Because it is a different approach to the same problem...it is a high-performance, single-thread, non-blocking infrastructure

... new school
Thursday, February 2, 2012
Node.JS is certainly changing the way we approach problems, and the way we
solve problems for the web !
All I can say is that ...
... at least it is happening to me and my team, and I hope it will help you to create amazing new products!
