To begin with, this technology is best suited for web applications that work in real time which require push features as well. Its architecture allows for easy data exchange, thus making communication between client and server absolutely smooth.
It is significant to see that this subtle change in the communication can lead to effortless development of remarkable applications. Companies largely depend on this technology’s essential features which let’s them come up with intuitive applications which run perfectly across different devices as required.
In simple words, this platform is suitable for the development of certain app products and not necessarily for all web development requirements. For instance, you would not expect it to be used for CPU related operations. This technology can manage large number of connections simultaneously, making it ideal for use in building highly scalable networking apps that are fast.
Node.JS basically works on one thread and eventually makes use of the non-blocking I/O calls, which further take care of the simultaneous connections. Due to this capability, Node can manage up to 1 million concurrent connections while staying light, efficient and fast.
Although this open source technology is great for many applications, it still has some drawbacks of its own. For instance, a single thread might get congested due to the simultaneous heavy processing, which can cause issues for clients due to the blocking of new requests. Similarly, a bubbled exception in the event loop of Node.JS can crash a program.
Luckily, developers can very easily manage these exceptions or errors by using tools and other prototypes which are meant to track the process and make a quick recovery in case of unhandled exception.
It all comes down to if you have chosen the right web development technology to make your product. If you are looking for a great web application that works in real time, is scalable and fast and one that can manage different connections simultaneously, then Node.JS is absolutely perfect for you.
