Some Tips for Ensuring Optimal Performance of your Node.js Apps

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.
