It is essentially utilized as a web front-end development tool and proves to be over a handy client for the building of cross-development platforms.
In addition to that, it’s also attained name because of its usage in numerous alternative standard platforms as well as React Native, PhoneGap, Titanium, Apache, NativeScript, Appcelerator, etc.
What is Node JS?
Moreover, it operates on one threaded event-based mostly loop to create all executions non-blocking. However, you can not think about Node.js as not a framework and it’s nothing to try to to with the PHP, .NET or JAVA.
There some Points to be noted that about Node.js.
- Node.js is an open-source source atmosphere
- Node.js is free
- Node.js runs on different platforms (Windows, Linux, Unix, Mac OS X, etc.)
Advantages of Node JS
- Node.js offers a Simple Scalability
- Simple to Learn
- Node.js is used as One Programming Language
- Advantage of Fullstack JS
- Famous for Offering High Performance
- The Support of huge and Active Community
- The Advantage of Caching
- Offers the Liberty to Develop Apps
- Obtaining Support for Normally Used Tools
- Handles the Requests at the Same Time
- Node.js is Extremely Extensible
One of the key benefits of Node.js is that developers notice it simple to scale the applications in horizontal also because of the vertical directions. The applications may be scaled in a horizontal manner by the addition of extra nodes to the present system.
It becomes a lot easier for them to begin using the Node.js at the backend. it’s easier to learn Node.js and consumes less time to figure with it.
Therefore, the advantage is that you simply don’t need to hire separate developers for backend similarly because of the front-end development. It saves each of your valuable price and time.
Node.js is blessed to own an oversized and active community of developers who persevere endlessly contributive towards its any development and improvement.
The open-source runtime atmosphere of the Node.js also provides the ability to cache single modules. Whenever there’s any request for the primary module, it gets cached within the application memory.
The developers don’t need to re-execute the codes as caching permits applications to load the net pages quicker and respond a lot of fleetly to the user.
Another advantage that Node.js offers to the developers is that the freedom to develop the apps and software system.
This is one essential feature, that remains absent in Ruby on Rails imposing certain tips. you’ll begin everything from scratch whereas developing applications.
With Node.js, the developers will get extended support for the various normally used tools. Let’s take an example. Suppose, you wish to check the source code of Node.js application; you can do so by using the Jasmin and different such unit-testing tools.
Similarly, if you wish to identify and install the project dependencies, you’ll be able to build use of npm, a strong package manager. you can use grunt for task running of the project.
Since the Node.js is providing the choice of non-blocking I/O systems, it comparatively helps you to method many requests at the same time.
The system will handle the synchronous request handling efficiently higher than others together with Ruby or Python. The incoming requests get lined up and are dead quickly and consistently.
The Node.js is thought to be extremely extensible, which suggests that you simply will customize and any extend Node.js as per their necessities.
You can also create the use of JSON to produce the scope for the exchange of data between the web server and also the shopper. It is also facilitated with built-in Apis for developing HTTP, TCP, and DNS Servers.

The Drawbacks of Node.js
Well, Node.js also has some cons which require to be essentially mentioned.
- Application Programming Interface (API) isn’t Stable
- Doesn’t have a Powerful Library Support System
- Asynchronous Programming Model
One of the key issues that the majority of the developers encounter is that the Application Programming Interface (API) keeps on dynamic at frequent intervals and doesn’t stay stable.
At times, a brand new API appears having a variety of backward-incompatible changes. As a result, the developers are forced to create changes within the accessible code bases to match the compatibility with the most recent version of the Node.js API.
The result is that the users are forced to require the support of common library for executing various tasks like Object-Relational Mapping (ORM), the process of the pictures, handling database operations, and XML parsing, etc.
This builds it difficult for the developers to even implement the common programming tasks using Node.js.
If you want to form the applications more scalable, the mandatory requirement is the adoption of the asynchronous programming model.
However, several developers could notice this programming model be more difficult in comparison to the linear interference I/O programming.
Another con of the asynchronous programming is the codes tend to become clumsy and also the programmers have to depend on the nested calls.
