Why Node.js is more popular than Ruby on Rails and other alternatives? Node.js has ability to handle the thousands of concurrent connections with single process and minimum overhead u sing the JavaScript developed the server applications and networking applications. There are some reasons which people choose Node.js.                     I.             Streaming Data                   II.             A real time applications like online games, collaboration tools and chat rooms etc.                 III.             Great Performance in I/O Processing  ...

Node.js was originally written by Ryan Dahl in 2009.

The ability to handle the thousands of concurrent connections with single process and minimum overhead using the JavaScript developed the server applications and networking applications. Some highlighted Node.js points are, a)       Single Page Applications b)      Streaming Data c)       A Real-time Applications like online games, collaboration tools and chat rooms etc. d)      I/O bound Applications e)       APIs based Applications f)        JSON based Applications g)       PROXY Applications

a)        It is an asynchronous and event-driven system. b)        Single-threaded event-driven system c)        It is very   lightweight and fast. d)        Tolling e)        Easy to configure f)         Node never buffering g)        It is highly scalable but single threaded. h)        Safe and secure.

Advantages:- a)       Single Page Applications b)      Streaming Data c)       A Real-time Applications like online games, collaboration tools and chat rooms etc. d)      I/O bound Applications e)       APIs based Applications f)        JSON based Applications g)       PROXY Applications Disadvantages:- a)       Nested callback hell. b)      In Node.js, any CPU intensive computation will block the responsiveness. c)       Dealing with files can be a bit of a pain. d)      In Node.js, the relational database is a bit of a pain. e)       It's asynchronous programming model not for synchronous model.

1) What is Node.js? Node.js is a JavaScript run-time built on Chrome's V8 JavaScript engine. Nodejs is an open-source , cross-platform and JavaScript run-time environment. It is a lightweight framework used to develop server-side web applications. Node.js is built upon Google Chrome’s V8 run-time —written in C++ , built for multiple operating systems and super fast. The use of JavaScript also means that transforming JSON data —the most common data interchange format on the Web—is fast by default. Node.js used for creating large scale application development, mostly used for video streaming websites, single page application, and other web applications. Setup a Node.js Development Environment on Windows, Mac and Linux - It is easy to  install Node.js  on  Mac ,  Windows  and  Linux .
