Share via:

Hiring a top-notch talent pool for an IT project has long been a challenge for most companies. Whether a startup or an experienced tech business, most face specific issues when looking to hire Node JS developers.

The popularity of JavaScript apps has been skyrocketing recently, with Node.js at the top of popularity charts and node js development companies in high demand. Node packages are growing faster than PHP, Java, Python, and Ruby altogether.

What Exactly Is Node.js ?

Node.js is a free of charge open-source server environment that uses modern Javascript on the server and runs on various platforms (Windows, Mac OS X, Unix, Linux, etc.). Designed to create scalable network applications, Node JS is built on Chrome’s V8 JavaScript engine. Unlike many other technologies, Node JS is well-scalable, as it relies on the non-blocking I/O model. It is JavaScript plus a bunch of C/C++ features.

What Is Node.js Used For?

Being a Javascript runtime environment, Node JS helps in the execution of JavaScript code on the server-side and the development of real-time network applications.

As of today, the area of usage for JavaScript has significantly expanded, so Node JS frameworks are increasingly used for server-side programming. Besides, Node JS is widely used in blockchain and Node.js machine learning.

How to Create a Node App

Node JS doesn’t require developers to learn another programming language, as they can use JavaScript for both server and client-side needs. Most of the front-end JavaScript objects, functions, and methods are available in Node JS.

The NodeJS package ecosystem npm is considered to be the largest ecosystem of open source libraries in the world, which makes it even more accessible. Node.js uses a concurrency model based on an event loop. And what’s great for Node JS developers is that thanks to this model, Javascript never blocks.

Node JS App Development

As almost all coders are familiar with JavaScript, they can quickly switch to it from any other language. Contrary to other web technologies, Node JS uses an event-driven architecture and runs on a single thread, so it is very lightweight. Node.js is also compatible with IDEs like Visual Studio and Eclipse, and supports simple code editors like Sublime Text and Notepad++.

In addition, Node JS is supported by a document-based model database (objects like JSON), unlike traditional SQL databases that implement relational models. It is convenient to use, as it can be hosted anywhere on the cloud-based hosting providers and web servers like Amazon, Microsoft, Google, etc.

How to Hire Node JS Developers

If you intend to hire Node.js developers for dynamic app development, you might not find the right Node JS developer onsite. You may stick to the idea of hiring a freelance Node JS programmer, but there will be no guarantees of code quality and dedication. Here are a couple of essentials to pay attention to before hiring a Node JS developer. 

Make a list of essential Node JS interview questions that you are going to ask your candidates: 

  1. Try looking into expertise first: experience in years and projects. 
  2. As Node JS is based on Javascript, pay close attention to overall JS skills. While knowledge of Node JS frameworks like Express, Sails, or other backend frameworks and languages are really nice to have, you can also check the knowledge of frontend technologies, such as React, Angular, HTML, CSS. Strong expertise in Databases (e.g. MongoDB) and cloud infrastructure (e.g. AWS) also presents a strong advantage in the resume.
  3. Observe the response time and communication manners. 
  4. Discover how flexible the candidates are. 
  5. Pay attention to their pricing and its transparency.
