Summing it up 

Node.js is a powerful run-time Java environment which provides developers with exceptional choices to create lively websites and applications that promote activities like live chatting. Hence a detailed knowledge of this technology is recommended to deal with it without any flaws. Node.js developers can rely on these resources to make the development process extremely effortless, and valuable.

The growth of Node.js is indeed tremendous. Its popularity is now far and wide. Node.js, with its applications written in JavaScript, is a cross-platform run time environment. A Node.js developer is provided with an event driven architecture. Also, an application's scalability and throughput are optimized easily because Node.js provides non-blocking I/O Application Programming Interface. With the JavaScript and modules, the web servers creation and networking tools creation is enabled by Node.js. The elegant API eases the complexity in developing server applications.

Coming to the performance part, an application should be easy to debug, refactor and develop. These days, Node.js has become very important for enterprises. APM or Application Performance Management as a solution can assist enterprises to monitor applications in real-time. APM can also help to drill down into call stacks. The other main advantage of APM is that it helps in finding out performance bottlenecks during live production. That said, how to get the optimal performance of Node.js applications? Here are some tips.

Ensure end-to-end visibility of Node.js application environment:

Application performance management automatically finds application topology and interdependencies. APM can also trace important business transactions which are based on production application behavior. Also, the solution of yours must be used in such a way to keep track of asynchronous calls done in the Node.js event loop. Make sure that you visualize and also prioritize the end-to-end business transactions performance in addition to application and infrastructure nodes.

Real-time detection of application errors:

Errors, exceptions that come from application components have to be detected in real-time by APM solutions. Performance tracking of various business transactions has to be done continually. This helps in discovering slow transactions which go beyond the actual range of performance. So, it is important to drill down to the real problem. After which, errors have to be fixed and exceptions have to be addressed. Hence, real-time detection eliminates the impact on the end users.

Applications have to be monitored at code-level depth:

The performance issue of any application has to troubleshooted by drilling down to the source code level. You must possess a solution which provides an in-depth monitoring of the application. This should come along with comprehensive call graph for all asynchronous calls which are made from Node.js event loop. Also, by drilling down from a mobile app or web browser, you must be in a position to locate hot spots in the application.

Know your end-user experience:

Keeping the performance of Node.js applications, you must monitor visually your web and mobile user experience. Doing so helps to recognize the code in the application that is negatively impacting the end-user. The issue has to be addressed prior to they sharing the experience on various platforms of social media.

Keep tab on databases and servers performance

For I/O rigorous web applications where frequent non-blocking calls to the databases are made, Node.js is well suitable. Hence, what is very important is to watch the performance of the supporting database, servers in Node.js applications context. Drilling down to the slow queries, stored procedures are required.

Are you aware of the fact that the rapid growth in the use of Node.js has compelled developers to sit back and take note of it? And did you know the fact that many popular and successful web applications and websites have used Node.js? Let your answer be a pronounced Yes or a feeble No. But before knowing which those successful websites are, let us know more about Node.js, and the reasons for it being preferred for web application development, these days. 

What is Node.js?

Node.js is a platform which has been built on Chrome's JavaScript runtime. Its applications are written in Javascript. Also, it is an open source and a cross-platform runtime environment that offers an event-driven architecture. Besides that, it offers a non-blocking I/O API, using which an application's throughput and scalability are optimized.

Notably, Node.js is a perfect choice for data-intensive real-time applications and for sites that are expected to witness a drastic growth in the number of users. On the other hand, an inbuilt library enables applications to act as a web server.

Invented in the year 2009, by Ryan Dahl, Node.js platform uses JavaScript and modules and allows to create web servers and also networking tools.  Also, its applications can be run on various servers – Mac OS X, Microsoft windows, and Unix.

Reasons to use Node.js for web application development:

It's fast:

Fast and scalable network applications can be built as the JavaScript execution is fast. The single threaded model with event loop is also highly helpful and allows handling multiple client requests. It is one of the major advantages of using Node.js for web applications. Due to the presence of event loop in Node.js, there is no necessity of creating more threads, even when the applications receive numerous concurrent client requests. Therefore, the application utilizes less memory.

Sharing is encouraged

It is all fine to share packages of library code. So if any problem a developer faces, The Node Package Manager(npm), with its repository of 50,000 packages, helps the developer with the solutions. Updating, sharing and reusing of code are therefore much easier.

Streams in Node.js

Since Node.js is asynchronous and event-driven, tackling of I/O bound tasks are extremely good. So, what are streams? They are UNIX pipes which enable easy reading of data from the source, and pipe the data to the destination.

Data synchronization between client and server

Data transfer between the client and server happens very quickly because Node.js enables writing JavaScript on both client and server side.

Ideal for real-time applications of Node.Js

If you are intending to build real-time web applications like chat, then it is the Node.js that is suited for its development. Plus, this platform is used in the development of games. Event based server, non-blocking driven server are best suited if the web applications get to handle a large number of real-time users.

The above are some of reasons for developers preferring Node.js for building web applications. Now let us have a look at some of the popular web applications and websites that have used Node.js. Some of them include the ubiquitous LinkedIn, the famed yahoo, the revolutionary Paypal, the successful Ebay, and so on.

Conclusion:

Node.js is certainly promising in the development of web applications, especially the real-time applications. However, for the development of such applications, it is highly imperative to choose a best Node.js development company which has a proven track record. And if you are a web developer, then it the time for you to take note of the gaining popularity of Node.js.
