What is node?
Node.js® is a platform built on Chrome's JavaScript runtime for easily
building fast, scalable network applications. Node.js uses an event-driven,
non-blocking I/O model that makes it lightweight and efficient,
perfect for data-intensive real-time applications that run across
distributed devices.

What can I do with
Node?
Http, networking, Websockets but also it is an invaluable tool for
developers

MILAN november 28th/29th 2014 – Ugo Lattanzi
Why is it so cool?

it’s fast
optimised (low resources)
runs everywhere

Visual Studio
addicted?
don’t worry, there is a free and open source plugin (NTVS) that turns
Visual Studio into a Node.js IDE
http://nodejstools.codeplex.com/
NTVS supports Editing, Intellisense, Profiling, npm, TypeScript,
Debugging locally and remotely (Windows/MacOS/Linux), as well as
Azure Web Sites and Cloud Service.

vash (@razor)
Vash is a template engine that offers a swift flow between code and
content using Razor Syntax
it supports master pages, partial, helpers and so on
it isn’t a porting of Razor View Engine but is very similar
the file extension for the views is .vash

vash (@razor)
partials are simple html files in the view folder
to include a partial in your view all you have to do is
@html.include(‘name_of_the_partial’)

(validation)
there isn't data annotation so validation is more "challenging" than .net
express-validator is a cool middleware for Express.Js that helps you to
validate input data
npm install express-validator —save

database
of course you can use MS Sql Server (npm install mssql —save)
but
MongoDb “could be better” with Node (npm install mongodb —save)
