Major NodeJS Pitfalls Committed by the Developers

For a few years now, Nodejs has been a brand name among developers everywhere. So, what exactly is all of this current buzz around Node.js that we’ve all been hearing about lately? What is the reason for its widespread acceptance and mistakes that needs to get avoid? Let’s take a closer look at all of this and much more. Node.js has been a topic of discussion for quite some time now, with its rapid development and popularity being attributed to it in recent years. Companies with a long history, such as Walmart and PayPal, have modify it, creating it one of the most well-known languages in use today. Nodejs, like many other platforms, is plagued by a slew of global challenges, many of which are the result of critical blunders made by the product’s creators itself.

What exactly is Nodejs?

Node.js is a programming language with a complicated definition. A programming language, framework, or library are not include in this definition. Nodejs is describe as a JavaScript environment that is build on top of Chrome’s V8 JavaScript engine, according to their online webpage.

Node.js may be thought of as a framework rather than a programming language. It is mostly use for backend operations, and it can/can be use in conjunction with frontend JavaScript frameworks such as Angular, React, Vue, and other similar technologies. Its architecture is comparable to that of Ruby’s Event Machine and Python’s Twist, among other languages.

In this post, we’ll look at some of the most frequent errors that developers new to Node.js make, as well as how to avoid making them in order to become a Node.js expert faster.


  1. Blocked event loop

In a single-threaded system, no two threads can execute simultaneously. The event loop pauses everything in Node.js since it operates on a single thread. Concurrent input-output activities are handled asynchronously here. A call to the database engine from Node.js, for example, enables Node.js to concentrate on other parts of the application. A piece of CPU-bound code in a Node.js instance with several clients connected may stop the event loop. The only answer is to deal with each instance separately. The objective is to avoid doing CPU demanding tasks on the front-facing Node.js instances that client connect to.

  1. Using the Callback feature more than once

Call-backs have been a staple of JavaScript from the beginning of time. The handling of events in web browsers is accomplish by sending pointers to (typically anonymous) routines that operate as call-backs. Call-backs were formerly the sole method for asynchronous portions of your code to interact with one another in Node.js, before promises were introduce. Despite the fact that call-backs are no longer in use, package developers continue to build their APIs around them. One typical Node.js problem that arises when utilising call-backs is that they are call more than once. After a package provides a function to perform something asynchronously, the function expects a function as its final parameter, which is execute when the asynchronous job has been complete:

  1. Using Integer Data Types by taking Numbers

Another mistake that far too many developers do is to use the wrong language. It’s important to remember that in JavaScript, numbers are treat as floating point data rather than integer data. If the numbers exceed the floating-point limit, it is likely that all of your computations will be incorrect. Because of this error, Node.js has earned the reputation of being unsuitable for complicate computations. While in reality, if the float bounds are properly maintain, you should have no problems at all.

  1. A large amount of material

It is not possible to construct an application using Node.js without following a specified convention. Generally speaking, frameworks that make use of Node.js are unopinionate, which means that they do not provide any precise standards for the way code should be write. Therefore, each application needs a customised strategy and, as a consequence, requires more experienced programmers who have established effective internal procedures for generating and maintaining code.

Bottom Line

So those are the most typical blunders that in nodejs application development make while working with Node.js, to summarise. It is true that Node is a fantastic language for developing applications. With a variety of current features that are meat to make app development quicker. For as long as you grasp the subtleties of Node.js and make a deliberate effort to avoid the pitfalls described above. You will be a happy, satisfied, and much more productive Node.js developer.
