Introduction to Node.js: Node.js is a non-proprietary and platform-independent runtime environment for implementing JavaScript code outside of a browser. However, NodeJS isn’t a framework and not a programming language. We frequently use Node.js for creating backend administrations like APIs for Web or Mobile Applications. It’s being used by enormous organizations, for example, Uber, Paypal, Wallmart, Netflix and many more.

Node.js Tutorial

A Node.js application runs in a solitary cycle, without making another string for each solicitation. Node.js gives many asynchronous I/O natives in its typical library that forestall JavaScript code from obstructing. Libraries in Node.js are built utilizing non-impeding ideal models, making hindering conduct the particular case instead of the standard.

Features of Node.js

Various awesome features of Node.js allow a developer to pick Node.js as his/her first choice. Some of them are as follows:

  • Open source: Node.js has an open-source network that has delivered numerous brilliant modules to add extra capacities to Node.js applications.
  • Incredibly quick: Node.js is based on JavaScript V8 Engine used in Google Chrome, which makes the code execution of its library quite faster.
  • Asynchronous and Event-Driven I/O: Every Application Programming Interface of Node.js library is Asynchronous. So, a Node.js-based worker never faiths that an API will fetch back the information.
  • Single strung: Node.js follows an individual node model with event cycle.
  • No buffering: While transferring video and sound records, Node.js cuts off the normal preparing time. Moreover, any information is never supported by the applications of Node.js.
  • Exceptionally Scalable: Node.js is profoundly adaptable because the occasion system causes the worker to react in a non-obstructing way.
  • Permit: Permit for Node.js is delivered under MIT.
  • MongoDB Wrappers API: Node.js stage contains a different module to coordinate MongoDB No SQL information base with applications. It gives a MongoDB covering API. We can utilize this API for composing JavaScript effectively to collaborate with the MongoDB information base. Node JS-mongoDB module utilizes Mongoose to interface with MongoDB information base.
  • Modularity: Significant feature of the Node.js Platform is that its modularity. Every single usefulness is isolated and executed as a different module or bundle. When we introduce the Node.js Platform, as a matter of course, it introduces just scarcely any modules. If our application requires different modules, at that point, we can, without much of a stretch, introduce and arrange them any time of our application advancement stages.

Advantages of Node.js

In Addition to the features of Node.js, there are various advantages. Some of them are as follows:

1. Simple Scalability: Developers want to use Node.js because it is effectively scaling the application in both even and vertical behavior. We can similarly add the other assets due to its flexibility of use. 

2. Ongoing web applications: To build a gaming application or call applications, Node.js is considerably best in terms of faster management. Similarly, the event loop stays away from HTTP over-burden for Node.js advancement. 

3. Quick Suite: Node.js is designed to run on Google Chrome’s V8 JavaScript engine. Node.js Event Loop handles all unusual activity, hence making Node.js to act like Quick Suite and creating all tasks faster like writing or checking the record, network association or record framework.

4. Easy to learn and code: Node.js provides an easy learn environment and makes coding easier because of JavaScript. Anyone can certainly learn and built the application on Node.js on the off chance that an individual is a front-end designer and have a decent grip on JavaScript.

5. Information Streaming: In Node.js, HTTP solicitation and reaction are considered as two separate procedures. These are information streaming, so when we evaluate a document at the assembling hour, it will reduce the existing time and make it faster when the data is presented as transmissions. It similarly permits you to transfer video and sound records at very high speed.

6. Hosting: Node.js application organization uses PaaS (Platform as a Service) and Heroku as the hosting platforms, which makes it more compatible and easier to use, without any issue.

7. Commercial Support: Most of the prominent organizations like Wallmart, PayPal, Microsoft, Yahoo are utilizing Node.js for developing their applications. Node.js utilizes JavaScript, so many organizations are joining backend and front-end teams together into a solitary unit.
