What is Node NW?
NW.js is an app runtime based on Chromium and node.js . You can write native apps in HTML and JavaScript with NW.js. It also lets you call Node.js modules directly from the DOM and enables a new way of writing native applications with all Web technologies. It was created in the Intel Open Source Technology Center.
NW.js (previously known as node-webkit) lets you call all Node.js modules directly from DOM and enables a new way of writing applications with all Web technologies.

Features:

  • Apps written in modern HTML5, CSS3, JS and WebGL.
  • Complete support for Node.js APIs and all its third party modules.
  • Good performance: Node and WebKit run in the same thread: Function calls are made straightforward; objects are in the same heap and can just reference each other;
  • Easy to package and distribute apps.
  • Available on Linux, Mac OS X and Windows

nw.js is an app runtime based on Chromium and io.js. For building desktop applications that will run on OSX, Windows and Linux.

NPM Install Commands
npm install nw

For Global Installation
npm install nw -g

Small Example For Getting Started

Step 1 : Create package.json:

{
  "name": "helloworld",
  "main": "index.html"
}

Note:
package.json is the manifest file in your app. It is written in JSON format.

Step 2 : Create index.html:

<!DOCTYPE html>
<html>
  <head>
    <title>Hello World!</title>
  </head>
  <body>
    <h1>Hello World!</h1>
  </body>
</html>
This is the normal HTML file. You can use any web technologies supported by latest browsers.

Step 3 : Run your app

cd /path/to/your/app
/path/to/nw .
/path/to/nw is the binary file of NW.js. On Windows, it’s nw.exe; On Linux, it’s nw; On Mac, it’s  nwjs.app/Contents/MacOS/nwjs.

Small Discussion About Mojito?

What is Mojito?

Mojito is an environment agnostic, MVC web application framework architected by Ric Allinson which supports agile development of web applications. ... Mojito is capable of running on both client(browser) and the server(Node.js) because both client and server side components are written in single language

Mojito provides seamless MVC framework to manage code base on server as well as on client side. The advantages of using Mojito are:

Single Language: Mojito is entirely built on JavaScript and hence the application code can run on server as well as can be deployed to client. This will remove the need for client to fetch data from the server.
Run-time Environment: Mojito has inbuilt capability to determine whether client can run JavaScript before deploying the code. If the client cannot execute JavaScript (JavaScript might be disabled at client side), then Mojito will execute the application code on the server.
Internationalization: Mojito has inbuilt library to handle Internationalization and localization.

Mojito has two unique features to empower you on this area.

Runtime context : which is a predefined set of dimensions/variables with a finite number of possibilities/values that will define the state of the execution at any given time.
Environment agnostic : the unique ability to run the same code in different runtimes. E.g.: browser, server, iOS UIWebView or any other phoneGap similar runtime.

Overview About Node.js

What is Node.js?

Node.js is a runtime environment and a library for running applications written in JavaScript outside the browser.

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications.

Node.js is an event based, asynchronous I/O framework that uses Google's V8 JavaScript Engine.

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.

It is used for developing applications that make heavy use of the ability to run JavaScript both on the client, as well as on server side and therefore benefit from the re-usability of code and the lack of context switching.

Some of the Applications that can be written using Node.js.

  • Static file servers
  • Web Application frameworks
  • Messaging middle ware
  • Servers for HTML5 multi player games

Normally it is an event-driven I/O framework for the V8 JavaScript engine.

Event-driven I/O server-side JavaScript environment based on V8

What is V8?

V8 is Google's open source JavaScript engine.

V8 is written in C++ and is used in Google Chrome, the open source browser from Google.

The basic philosophy of node.js is:

Non-blocking I/O - every I/O call must take a callback, whether it is to retrieve information from disk, network or another process.
Built-in support for the most important protocols (HTTP, DNS, TLS)
Low-level.
Do not remove functionality present at the POSIX layer. For example, support half-closed TCP connections.
Stream everything; never force the buffering of data.

Note:
Node.js is different from client-side Javascript in that it removes certain things, like DOM manipulation, and adds support for evented I/O, processes, streams, HTTP, SSL, DNS, string and buffer processing and C/C++ addons.
