What Exactly Is Node.js ?
Now lets draw down some major advantages and disadvantages of Node.js
Pros Of Node.Js
It Offers Easy Scalability
Node.js allows developers to scale applications in horizontal as well as vertical directions which is one of the biggest advantage of the technology . The scaling of the application in horizontal manner is possible by just adding nodes to existing system .
Easy To Learn
As one of the world’s most popular programming language , most of the front end developer has good grip on this technology . It becomes much easier to learn in comparison with other technology and thereby consumes less time to work with it .
It Uses Single Programming Language
Offers High Performance
Facilitate Development Of Apps
Another big advantage of using Node.JS is it facilitates mobile app developers freedom to develop apps and software . You can actually build the app right from the scratch using this technology , which is not in the case of Ruby On Rails or other platform by imposing some limitation .
Getting Support Of Large And Active Community
Cons Of Node.Js
Application Programming Interface (API) Not Scalable
We can say one of the key problem that developers might encounter while developing the API’s , it needs to keep on changing at frequent intervals and hence does not stay stable .
There may be times that new API appears wherein you have to work on number of backward incompatible changes , thus making it incompatible to match with latest version of Node.Js API .
Does Not Have Supported Strong Library System
Unlike other , it does not have strong library system . As a result developers are forced to use common available libraries for various orientation of task such as processing of images , handling database operation , XML parsing and more .
Asynchronous Programming Model
This programming model facilitates scalable application making. However , many developers may find this usability difficult while comparing with linear blocking I/O programming .
