«Node.js is a software platform that is used to build scalable network (especially server-side) applications. Node.js utilizes JavaScript as its scripting language, and achieves high throughput via non-blocking I/O and a single-threaded event loop.

Node.js contains a built-in HTTP server library, making it possible to run a web server without the use of external software, such as Apache or Lighttpd, and allowing more control of how the web server works.»

Install on OSXUsing a package:Simply download Macintosh Installer

Using homebrew:brew install nodeUsing macports:port install nodejs

Install on LinuxUbuntu, MintExample install:sudo apt-get install python-software-properties python g++ makesudo add-apt-repository ppa:chris-lea/node.jssudo apt-get updatesudo apt-get install nodejsIt installs current stable Node on the current stable Ubuntu. Quantal (12.10) users may need to install the software-properties-commonpackage for the add-apt-repository command to work: sudo apt-get install software-properties-commonAs of Node.js v0.10.0, the nodejs package from Chris Lea's repo includes both npm and nodejs-dev.There is a naming conflict with the node package (Amateur Packet Radio Node Program), and the nodejs binary has been renamed fromnode to nodejs. You'll need to

symlink /usr/bin/node to /usr/bin/nodejs or you could uninstall the Amateur Packet Radio Node Program to avoid that conflict.

Install on WindowsUsing a package:Simply download Windows Installer.

Using chocolatey to install Node:cinst nodejs or for full install with NPM:cinst nodejs.install

✦ A lot of manual work

✦ More than 5 different sources for analysis and counting

✦ JSTD: js test driver for running tests on CI

✦ Strange custom ruby scripts (still have no idea what they were used for :)

✦ Sonar showed only back-end code

✦ Code coverage was to get in a separate application which made the automatic analysis even more complicated

✦ Code health was counted in exel with its magic formulas that mysteriously worked hiding the real problems

Total CRAP...

✦ We’ve refused from everything we had before but the existing tests

✦ We’ve decided to switch to node.js for non-functional requirements

✦ We’ve chosen grunt.js for running node.js tasks (running unit tests, counting code coverage, creating reports for Sonar, checking the code semantics and complexity: jshint)

✦ We’ve excluded any manual intervention: sided applications for code coverage, exel creepy files, etc.

✦ We’ve put counting code health on Sonar’s shoulders for back-end as well as UI

✦ We’ve fastened unit testing on CI

✦ We’ve prevented the developers from failed builds and have given them the clear system for code quality analysis and correction

What is Sails.js?

Sails.js make it easy to build custom, enterprise-grade Node.js apps. It is designed to mimic the MVC pattern of frameworks like Ruby on Rails, but with support for the requirements of modern apps: data-driven APIs with scalable, service-oriented architecture. It's especially good for building chat, realtime dashboards, or multiplayer games.

What is Sails.js?

✦ Sails.js is database agnostic. Its ORM, Waterline, provides a simple data access layer that works, no matter what database you're using.

✦ Sails.js automatically generates a RESTful JSON API for your app. That means you don't have to write any backend code to build simple database apps.

✦ Realtime Socket.io requests are routed to your controllers the same way as everything else: with resourceful conventions and URL mappings.

✦ Sails.js provides basic security and role-based access control by default, and you can add as many custom policies as you like.

✦ Because Express and Socket.io share the same configurable session store, all of your security policies are reused for realtime WebSocket requests as well.

✦ Sails.js has automatic asset minification. With Sails, you just put your files in the proper folder and they are automatically included in your layout. Then, when you're ready to go into production, they are minified and gzipped to preserve as much bandwidth as possible.

✦ If the URL is not specified in config/routes.js, the default route for a URL is: /:controller/:action/:id where :controller, :action, and the :id request parameter are derived from the url.

✦ If the requested controller/action doesn't exist: - if a view exists ( /views/:controller/:action.ejs), Sails will render that view - if no view exists, but a model exists, Sails will automatically generate a JSON API for the model which matches :controller. - if no view OR model exists, Sails will respond with a 404.
