desperate to know:
What is node.js?

focus on the
WHAT!
What is Node.JS ?
Thursday, February 2, 2012
5. Let’s better
focus on the
why and
how!
What is Node.JS ?
Thursday, February 2, 2012
6. To give you just a little bit of
context, for those who haven’t
hear about node, let’s just say
that ...
Node.JS is a program that can
do anything Apache can do,
and much more...
... and much
more faster ...
Thursday, February 2, 2012
7. Why are some many
developers excited about it?
Why you should pay
attention to it?
Why Node.JS ?
Thursday, February 2, 2012

HTML5, we can see
some very
interesting trends.

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

languages now days...

I want to explain
this through an
example...
Thursday, February 2, 2012
15. 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
16. Well, it is just
Javascript...
Is this SSJS ?
It doesn’t matter
where it runs if
we have a
runtime for it...
Thursday, February 2, 2012
17. Creating code
that can run in
different envs
is not new...
... but crossing the
bridge bet ween the
server and the client is
definitely new
Thursday, February 2, 2012
18. Why is this
important?
and for whom?
Why does this matters ?

lot, especially - context switch for
for developers. devs is bad for business

enhancement and
t witter
graceful degradation are
example ...
now possible...
Thursday, February 2, 2012
20. Let’s talk more about the ... there is a new vector
benefits of using the same that can affect our
language everywhere... products drastically:
variable connection
speed (past vs future)
Javascript everywhere...
How to personalize the way our
... example of the
product runs:
kind of product
- per user
we want to
- per request
build...
- per connection speed

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

was...
Thursday, February 2, 2012
33. How?
how does it do it?
Is that even possible?
Thursday, February 2, 2012
34. Because it is a different approach to the same problem...
it is a high-performance, single-thread, non-blocking
infrastructure
Thursday, February 2, 2012
37. All I can
say is
that ...
Node.JS is certainly changing the way
we approach problems, and the way we
solve problems for the web !
... at least it is happening to me and
my team, and I hope it will help you
to create amazing new products!
