Node.js has become very popular in the tech world. Now days, it is used by some top-notch technology companies like Microsoft, Yahoo, Ebay and many more. You may have a faint idea of how Node.js works or might not be aware of it. But, you might not have a good understanding of when and why it should be used. Here we are sharing some insightful information of Node.js to make sure you catch the core of it to be used further to build fantastic things. But before that, let us first understand what exactly is Node.js.

What is a node.js?

Node.js has seen an important growth in the past years, with big companies such as PayPal adopting it. More and more people are adapting Node.js. Node.js is a run time system for creating server-side applications. It’s best known as a popular means for Java script coders to build real time- web APIs.

The Web is changing

The web used to be about consumption. Viewing web pages, watching videos, looking at pictures. Users around the world want to interact with each other, and they want to do it in real time. Gaming, chatting, constant social media updates, collaboration- each of these features requires real time, communication between clients, users and servers across the web.

Enter Node.js

Node.js is an event-driven, server-side JavaScript environment. Node runs JavaScript to use the V8 engine developed by Google for use in their chrome web Browser. Leveraging V8 allows a node to provide a server-side runtime environment that compiles and executes JavaScript at lightning speeds. The major speed is increases is due to the fact that V8 compiles JavaScript into native machine code, instead of interpreting it or executing it as byte code. The Node is cross platform, open source, running on Mac OSX, Windows and Linux.

But JavaScript? On the server-side? Why? Through JavaScript has traditionally been relegated to menial tasks in the web browser, it’s actually fully-functional programming language, capable of anything that more traditional languages like Ruby, Java, C++. Java script has the advantage of an excellent event model, ideal for asynchronous programming. Java is also a ubiquitous language, well known by millions of developers.

Here are the things you need to know about it:

Java Script Object Notation : JavaScript Object Notation is a compound, practical, widely popular data exchange format. Java Script Object Notation has enabled JavaScript developers to quickly construct APIs and foster interoperability at scale- a key objective for a Node.js coders.

JSON and JavaScript have reinforced each other’s importance. In early days of the web, dynamic data in the browser had to be manipulated, filtered and operated on by the only reasonably comprehensible non plugin language available. JavaScript. Regardless of its original network- presentable format, data needed to be Marshalled into a ascriptive object. The dependence of JSON for general purpose data description gave rise to document-oriented NoSQL databases such as MongoDB and CouchDB. It’s all JSON all the time today.

Node Package Manager works Broadly : Speaking of managing library dependencies, the node package manager deserves to be called out. Node package Manger is the root of almost all deployment systems for a Node.js and underlies the many platform-as-a-service providers for a Node.js, actually making it somewhat easy to move smaller applications between providers.

Instrumentation: Finally, Node.js is well instrumented for production usage. What that means is that they’re the tools to help bring an application to full production performance and readiness. As with any technology, there are areas where more documentation tools, and best practices could be helpful. But as Node.js heads towards its next major release, it’s on the fairly solid footing.
