7 Things You Should Know About NodeJS

As I am, I think you are also new to this Node.JS, so let’s begin with a brief introduction of the same. After searching about it from all sources whatever I found, I would like to share it with you:

It was developed by Ryan Dahl in back 2009. Node.JS is an open source server environment, uses JavaScript on the server, it’s free and the main advantage is it runs on various platforms  (Windows, Linux, Unix, Mac OS X, etc.). Node.js also offers a rich library of various JavaScript modules which are responsible to simplify the development of web applications using Node.js to a great extent.

Node.js = Runtime Environment + JavaScript Library

Key Features of Node.js

The following are some of the interesting features that make Node.JS the first choice of software architects:

• Event Driven and Asynchronous − All the APIs (Application Interface Programming) of Node.js library uses asynchronous programming, i.e non-blocking. It is an essential means that a Node.js based server never waits for an API to return data. The server then moves to the next API after calling it. Moreover, a notification mechanism of Events of Node.js helps the server to get a response from the previous API call.
• It’s Very Fast − Node.js library is very fast in code execution as it is built on Google Chrome’s V8 JavaScript Engine.
• Single Threaded but Highly Scalable −There is the use of a single-threaded model with event looping in Node.JS. The event mechanism supports the server in order to respond in a non-blocking way plus makes the server highly scalable in comparison to traditional servers which therefore create limited threads to handle requests. It uses a single-threaded program that can provide service to a much larger number of requests than the traditional servers like Apache HTTP Server.
• No Buffering − Node.js applications, they, never buffer any sort of data. They simply output the data into chunks.
• License − Under the MIT license, Node.js is released.

Now you might have the question, Who uses this Node.JS??? And What it does??

Here is the answer to the first question, Following is an exhaustive list of some application and companies which are using Node.js. This list includes eBay, General Electric, GoDaddy, Microsoft, PayPal, Uber, Wikipins, Yahoo!, and Yammer to name a few.

Answer to the second question, Node.JS does:

• Open, create, write, read, delete, and close files on the server
• Modify, delete, and add data in your database
• Collect form data
• Generate the dynamic content of the page

Node.js is a proto-server; we have to set up each and everything with Node.js to make it work. It responds to different types of requests, and each request can even initiate other requests to another part of the system. This is called an event loop, and it’s a part of the runtime codes. If you are looking for a Node.js development company, then you will have a lot of choices. Making a web app based on Node.js is only a matter of contacting the right company and finalizing the project. Therefore, there are certain other features which we don’t know about Node.JS, Let’s see here:
