Learn Node.js Programming Free - Node Js Offline tutorial complete guide with interview question and glossary. Node.js can be defined as a dynamic, cross-platform and open-source JavaScript framework or runtime environment that is built on the Google Chrome JavaScript V8 engine. Node.js, developed in 2009, was initially implemented as a client-side scripting language. Nowadays, it is used to execute JavaScript code and scripts that run server-side to create dynamic web pages.


Node.js tutorials will help you learn the essentials of Node.js starting from the basics to an advanced level. These tutorials are broken down into sections, where each section contains a number of related topics that are packed with easy to understand explanations, real-world examples, useful tips, informative notes, and "points to remember" section.


What is Node.js?

Node.js is an open-source, cross-platform runtime environment used for the development of server-side web applications. Node.js applications are written in JavaScript and can be run on a wide variety of operating systems.

Node.js is based on an event-driven architecture and a non-blocking Input/Output API that is designed to optimize an application's throughput and scalability for real-time web applications.

Over a long period of time, the framework available for web development was all based on a stateless model. A stateless model is where the data generated in one session (such as information about user settings and events that occurred) is not maintained for usage in the next session with that user.

A lot of work had to be done to maintain the session information between requests for a user. But with Node.js there is finally a way for web applications to have a real-time, two-way connections, where both the client and server can initiate communication, allowing them to exchange data freely.

Why use Node.js?


We will have a look into the real worth of Node.js in the coming chapters, but what is it that makes this framework so famous. Over the years, most of the applications were based on a stateless request-response framework. In these sort of applications, it is up to the developer to ensure the right code was put in place to ensure the state of web session was maintained while the user was working with the system.

But with Node.js web applications, you can now work in real-time and have a 2-way communication. The state is maintained, and the either the client or server can start the communication.



Node.js Features and Benefits

Most web developers implement Node.js due to its amazing and powerful features. Some of the features of Node.js are:

Faster code execution
Highly scalable
Non-blocking APIs
No buffering
With such wonderful features, Node.js is widely used for creating server-side and networking applications. The following are the key areas where Node.js is widely used:

I/O-bound applications
Data streaming applications
Data-intensive real-time applications (DIRT)
JSON API-based applications
Single-page applications
There are many companies currently using Node.js such as eBay, General Electric, GoDaddy, Microsoft, PayPal, Uber, Yahoo!, IBM, Groupon, LinkedIn, Netflix and many others.
