Learn The Basics Of Node.Js
It is an open source, free for all tools/platforms for all the developers around the globe, it basically helps in developing dynamic I/O WebPages which are scalable and can handle big amount of data on network based applications. It basically uses an I/O model which is event driven, light-weight and efficient, comes handy for sites using video streaming, single page applications, and other intensive web pages.
Some features of Node.js are as follows:
1> Open license: Free for all developers without any conditions.
2> Single thread: Node.js is a single thread, which implies it uses an event-driven mechanism which helps in executing a large number of requests compared to other traditional servers (Http Apache server).
3> High-speed videos: Node.js handles huge chunks of data resulting in zero to the no-buffering scenario.
5> Event Driven: Node.js applies a non-blocking event driven procedure, which means it never settles for data response from APIs and instead it serves the request of other APIs and letting a notification process handle the response from a previously served API (Application Programming Interface).
Stepping in some details the important aspects of node.js are: Debugger, Streaming, DNS, Domain, Global, Net, Modules, Error Handling, Console, Cluster, Add-on, Buffer, Callbacks, and Crypto. These Functionalities are specifically well suited for: Data Streaming Applications, Data Intensive Real-time Applications (DIRT), JSON APIs based Applications, Single Page Applications, I/O bound Applications.
Node.js is not recommended for highly CPU intensive tasks and multi-threaded programming. Also, it does not support relational database. Node.js has a tendency of changing in the back-end, so a developer has to take additional steps to monitor the stable running.
As Node.js is an asynchronous programming language, while it may be a good solution to the concurrency problem for that to run successfully a developer has to implement callbacks and ends up with a lot of nested callbacks to attend.
To some it all up it may not be a trendsetting programming language, but it has made a huge impact in the verticals it is being implemented and would be hard to replace. Node.js has stepped up its game from the time it was introduced, which has helped it to make an impact on its usability over the globe. Some of the present day’s Big shots use node.js as their savior, the list includes eBay, General Electric, Go Daddy, Microsoft, PayPal, Uber, Wiki pins, Yahoo!, and much more.
So if you are looking to master this wonderful technological development, get yourself registered for a Node.js course and witness how easy things become for you.
