9 Common Mistakes Node JS Developers Should Avoid!

In today’s era, technology is always changing and growing. And among the various technologies for web application development, Node js recently has emerged as one of the optimum server-based platforms. 

Nodejs is one such framework that works both ways as it establishes two-way communication between the client and server in real-time so that the sharing of files, documents, or any other data becomes less complex. The other key factor that has made Node js development quite popular among businesses, node js developers, or node js development company India is its swiftness to create scalable network applications. Moreover, this framework is light-weighted and effective that comes with the richness of a non-blocking I/O model and without any hassles operates on a range of distributed devices.  Though it is quite popular for its simplicity, reliability, and efficiency, still developers need to be on their toes in order to avoid common mistakes and get acquainted with the things on how to maximize the benefits of node js development application.  So, let’s walk you through the common Node.js mistakes that every developer should avoid. 

Expecting Callbacks to Run Synchronously

When it comes to executing the node code, the node js developers need to make sure that the subsequent tasks should have proper and aligned callbacks. In case, the previous task is not completed, then the following functions may not function up to the mark. 

Forgetting to Test and Inspect the Codes

Being a node js developer, you need to be always mindful and religious in testing the code once written whether it is able to fetch the desired result or not. Well, for testing, there is a range of user-friendly and effective tools available in GitHub, where you can easily execute the files for testing. Usually, Node JS web development company work out on this and leverage the tools for testing. 

Missing on Development Tools

For high efficacy, Node.js code normally needs particular development tools and certain functions. For instance, when you make certain changes in your code, you need to refresh the browser to see the changes. Moreover, you can even restart the segment instead of refreshing it. When you miss out on doing these or leveraging any optimum development tools while working, you would not be able to get desired results once your static code changes. 

Unknowingly Blocking the Event Loop

When it comes to coding with Node.js, this programming language has a single thread on which it runs. If by accidentally you called out a method that blocks the event loop, you will face a hurdle as the complete execution of your instilled code would come to stop.  Whenever you parse a huge JSON payload, better to highlight the syntax of a large file of the backend code, or you can parse the important output just in a single shot that would lead to blocking the event loop.

Callback Hell

In your Node js development, Callback hell is also regarded as deeply nesting callbacks. It is not a mistake that would stop the execution, although, it may lead to losing control over your code. Callback hell will make the source code unclear and unreadable by other developers. 

Multiple Executions of Callbacks

When you re-execute and refresh your written code to see how quickly it crashes, you may find a scenario where multiple callbacks have been executed mistakenly. In case, you might have forgotten to return the first call and may end up calling it for the second time. 

Supervise Your Code

It is very important for any node js developer or node js development service to continuously monitor and check your code to cross-check how effectively it is written. Running it and knowing the time delays in your event loop, you need to observe the CPU and memory usage of the code, which should be done properly. 

Choosing The Console.Log Rather Than Debug Library For Debugging

For the debugging process, most node js developers use Console.log. But, it is advisable to choose and use the debug library instead. This debug library is technically designed to work for this particular task and hence, you can easily protect the logs from getting printed out in the debug mode. Undoubtedly, this will help you to keep your files and documents safe and protected against any unwanted threats and scams. With the secure node js development services, you can safeguard all the crucial files.

Presuming Numbers to be Integer Data

Primarily any developer can commit a mistake when it comes to numbers as they regard it as integer data. But, in reality, they are floating point numbers in JavaScript. So, if anything goes wrong with the limitations of the float then definitely calculations can also go wrong. Interestingly, when it comes to integers and floats, there are different operations running specifically for each category. And, if you are quite accustomed to these processes and remember them very well, you are going to receive fruitful results. 

Closing the Code!

Among the various frameworks, Node.js is one of the finest frameworks loaded with superior features and flawless codes. More importantly, it helps in designing and developing more complex applications with the help of easy coding that it provides. With more complex node js development, better hire node js developer delivering best solutions.   No doubt, these days numerous businesses and organizations are looking for using Node.js for their sophisticated applications. And, if you are one of them, it is better to hire node js developers or partner with node js development company India for the exceptional nodejs applications.
