Unveiling the Potential of Node.Js, Introduction to Node.Js:
Advancements in the field of Science and Technology cannot just be attributed to the coders and developers which are out there working on several apps and software. Since it is an ever-growing industry which always demands changes to cater for the needs of the ideas which continue to pop in the head of thinkers, the entire trophy of success is equally shared by latest languages and frameworks. Here in this article, we are about to unravel another potentially capable and trending platform which is known as Node.Js. This informative read will provide the readers with an introduction to how Node.Js works?
Node.Js is basically a server-side platform whose basis has been laid by JavaScript. The whole analogy has been orchestrated and framed to existence in the Google Chrome’s built-in JavaScript engine known as the V8 engine. The person who came forward and implemented the idea, is known by the name of Ryan Dahl. After much effort, he managed to launch the very first version of his newly built platform in 2009.
Many would question the existence and the motivation behind the Node.Js. Don’t worry folks as we have prepared a full meal for you which will be enough to handle your appetite to learn. The main reason behind introducing a new platform was to provide a fast and scalable network application which has the ability to create scalable, data-intensive and perfect applications which have the potential to run on several distributed devices.
Node.Js offers hundreds of features and very few we will be mentioning here. Prior to moving towards the salient features of Node.Js, it is imperative for our clients to know that Node.Js is totally an open source platform. Even more so, it is a cross-platform and runtime IDE for the development of effective server-side apps and even networking apps as well. Since it is a cross-platform framework, you can use its several flavors on several operating systems. Be it Linux, iOS or Windows, it works in all platforms without ruining the overall symmetry of your partitions. Node.Js also provides a huge variety JavaScript modules and libraries which aid in developing web applications to a much larger extent.
Salient Features of Node.Js:
The reasons why most of the software architects are now shifting towards Node.Js are as follows.
1. Asynchronous:
Node.Js comes with several APIs. It is asynchronous, which is synonymous to the fact that it can’t be blocked. All other platforms of app development have to wait for the processes to return some values so the next process can be triggered. On the contrary, the Node.Js is totally immune to the wait which is done in hope for returning data from an API call. The server on which the app is being built, comprises several interconnected modules which are in direct communication with the server. The responses are monitored via a notifications module while the server moves on to the next API so that the flow remains un-altered and un-hindered.
2. Fast and Robust:
JavaScript is known to be a fast framework and so is the Node.Js. It has been developed on Chrome’s most credible engine which is well-known in almost all the technological circles as one of the best engine which does code crunching in seconds rather than others in which you have to get your dinner after clicking on the debug mode.
3. Uni-Threaded but Scalable:
We hope you all have some know-how about the thread concept which is made known to us in fourth or maybe fifth semester of our degree of Computer Science. We also are aware of the fact that single threaded systems are slow and never keep up the pace with that of the processor or that of the primary memory. Unlike other systems which create multiple threads to handle the requests, Node.Js uses only one thread which is coded in a loop to perform the task of getting in touch with the developer after receiving unblocked responses from several APIs which were asked to report once they receive something from the calls server made.
Other systems use Apache Http Server which is good but is always outranked by our most amazing platform known as Node.Js.
4. Un-Interrupted Services and Utilities:
Open up the app store and download any of the apps listed there. If the app you’ve downloaded is a video streaming app, it will for sure suffer from buffering. If it is a gaming app, after a certain time period, you will find your phone lagging just because you are playing this game and not listening to your favorite song simultaneously. The reason in, these application brings out the data and feed the apps with chunks of data. On the other hand, the Node.Js based application sends and receives the data in stream.
5. Licensed Platform:
The Node.Js platform is totally registered under the highest authority which is known as the MIT license and we comply by all the rules and regulation mentioned in EULA.
Utility of Node.Js:
Since its inception, there are several platforms which are using Node.Js as their primary platform for application development. The list is getting lengthier day by day but to name a few, we have Ebay, Uber, Wikipins, Yahoo!, Microsoft, GoDaddy, General Electric and Yammer.
Many ask the question as where should we use the Node.Js platform or for what kind of applications, the mentioned platform will be the most optimal solution. Folks, if any one of you is going to build an application which is an I/O bound application, Data Intensive Real-Time Application, JSON based application, Data Streaming Application and even if is a single page application, the Node.Js is the best platform. As your advisors, we would suggest not to use Node.Js for CPU intensive applications.
Conclusion:
As a matter of fact, whatever the cons may be, the pros are going to outrank them when we are talking about Node.Js. It is one of the best platforms one has ever come across. Prior to moving somewhere else, give the Node.Js a try and you won’t regret it.
