Technology Report on Node.js

Q1. What is the selected technology? (Basic concepts, definitions, features)

Traditionally websites were made using HTML and CSS. Over the time when websites became heavier and complicated, scripting languages like PHP, Python, and Perl were used with front end developed in previous mentioned technologies (HTML and CSS). JavaScript was introduced and made the web pages more interactive. With time and increased usage, jQuery was introduced. These were libraries of JavaScript functions used frequently in the web pages. But still people using these technologies were called “JavaScript User” and not “JavaScript Developer”. Node.js allows you to run JavaScript code on server side, outside the browser.

When the node.js web server receives a web request, it handles this request to a listener object to process the response. Meanwhile this web server will remain ready to accept any new web request. And the previous response handling will remain in a queue for performing the rest of operations. All the function calls within node.js context are non-blocking input-output operations. In node.js environment, the performing operation is executed by one object and the results of the operation are handled by the callback functions. This makes it lightweight and efficient and perfect for data intensive real time applications, which can run across distributed systems.

Q2. Why is the technology important?

Traditional web applications like Ajax and Comet are generating heavy load on web servers. Applications like chat or multiplayer browser games which use many concurrent connections and in which response times are essential are some of them. This is where Node,js scores extra points as compared to traditional scripting languages. It caters the need to develop fast and scalable applications particularly when you are talking about highly scalable web servers.
Also the fact that it uses the very common language of JavaScript, and it is a very easy way for developers to create very fast and very scalable servers.
Node is ideal when we need to do several things at the same time. The developer does not have to worry about code accessing the same data structures
