Some Common Mistakes Node JS Developers Commit While Building A Website

 


Undoubtedly, Node JS is the main web application layout, which is being used by many of the dominant market players such as Netflix, LinkedIn, Reddit, PayPal, Amazon, and more. Node JS did not take much time to become one of the most prominent web development architectures by firms and developers around the world. The credit goes to its outstanding capabilities, functionalities, and stability. Over 43% of the Node JS devs out there utilize the programming language to build robust start-up applications. Apart from this, 85% of them use it to build web applications.

Due to its great features, support, and developer community, Nodejs is picked by not just big corporations and companies but by enterprises as well.

Reports unveil that Node js development reduces development costing up to 58% and that it can optimize the app performance by 50%.

But generally, Node js developers commit some common mistakes, which are given below.

Some Common Node JS Web Development Mistakes Developers Make

1.   Not Concentrated on Utilizing Necessary Development Tools

One of the most common mistakes beginners and even professional developers make while developing websites through Node JS is that they don’t utilize significant development tools. There are thousands of tools and modules that make programming in Node JS easier. For example, whenever an improvement is made on the source code, the web browser requires it to be either restarted or refreshed to check the modifications in effect. If they won’t do so, then they won’t be able to see their desired results and delaying the development time. So, developers are recommended to fix the concern.

2.   Blocking Event Loop Mistakenly

Doesn’t matter what, but we have to accept the reality that Node JS is single-threaded and limits us from using several aspects of our applications at a time. So, if you intentionally or unintentionally launch an aspect that blocks the event loop, the whole program standstills. For example, when you are willing to insert a code to NodeJS when the language is trying to fetch a document or information from its database, you unintentionally block the event loop. To prevent this, it is perfect if you work on a case basis.

3.   No Proper Testing

Node JS development is merely finished when it has been verified for outputs and performance. So, it is not sufficient if you just create your code for a website or app you build but for tests too. Generally overlooked, testing makes sure your app or website is optimized for performance and becomes full-proof. Run repeated tests to prevent pitfalls and if you’re so concerned about creating tests, understand that there are a lot of tools available on GitHub like Jasmine and Mocha. These tools can simplify the process of running tests and inspecting your code.

4.   Multiple Callback Execution

Also called thoroughly nesting callbacks, it occurs when there are multiple nested callbacks. With multiple callbacks, it becomes very difficult for a developer to go through, spot, and debug their code. However, contrary to misconception, multiple callback execution can be prevented with the use of promises. No, we aren’t saying that you need to swear or make an oath but utilize promises. The promise returns you a value to confirm and verify the processing of an asynchronous function. And this makes your code appear clear and concise.

5.   Expecting the Code Would Execute Synchronously

Novice Node JS developers might be acquainted with synchronous code run from earlier programming languages and modules they have functioned on. Until and unless defined by a certain statement or condition, codes get executed subsequently in a series. Although, in NodeJS, with its callbacks hell, functions might not perform well until its adjacent task is completed.

6.   Dynamic Modification in Code

For Node JS developers, it is good to have a systematic and seamless approach to programming. An ideology like build-as-you-progress or Carpe Diem doesn’t function well with the Node JS programming language. If you have this approach, you will end up creating needlessly long and complex codes, increasing the concern we explained previously. To keep your code concise, you need to have a clear-cut idea of your whole project, its code trajectory, and development stages.

7.   Practicing for Writing Lengthy Codes

Based on the practice and past experiences, again, programmers would generally keep writing lengthy and complex codes on Node.js. Though, this is the approach we have to change while writing code in Node JS. Until Node.js is a matter of concern, it is good to stick to tiny and shorter code. Making your codes precise will open a way for seamless and faster execution of them.
