Node.js library consists of many tools and IDEs so it is important that your candidate knows how to navigate among them. A good developer should have some Node.js projects in his/her portfolio and show active participation and contributions to open-source projects. This not only proves solid knowledge of the framework but also proves the developers is a passionate engineer and team player.

Understanding of other front-end technologies

Front-end design patterns development obviously goes beyond the knowledge of Node.js. It refers to what the end-users see therefore a good understanding of front-end design and development including HTML and CSS is necessary for Nodde.js developers.

Efficient code

The code written by your candidate should be object-oriented. Ensure he/she follows standard practices for continuality.

Knowledge of Node.js frameworks

Frameworks expand the Node.js ecosystem, adding features and functionalities. That is why it is important your candidate knows some of them and can choose the most suitable one. Most often here we can talk about the Express functional framework, MVC frameworks like Strongloop or Sinatra and, of course, Nest.js for the back-end development.

Error-handling skills

Make sure the developer you want to hire knows how to handle errors and how to log them. Syntax manipulation and troubleshooting are basic problem-solving skills of a good Node.js developer.

RESTful APIs and API Communications

Every Node.js developer needs to know how to interpret API codes, meaning, know how to handle interactions between multiple systems.

Asynchronous Programming

Node.js is all about asynchronous programming as it significantly decreases the waiting time for requests. Since it is still a relatively new concept, not every developer will have a proper understanding of its workarounds.

Database scheme creation

Database management is a crucial skill to have in order to develop successful Node.js applications. The right candidate should know how to create them for business processes and how to integrate multiple data sources and databases into one system seamlessly.

User Authentication and Authorization

A good web developer should have a working knowledge of user authentication and authorization between multiple systems, servers and environments.

Experience in Data Protection

How to find Node.js developers?

When hiring a Node.js developer, there are three general routes you can go: hiring in-house, finding a freelancer or outsourcing. Each of them has its pros and cons, so let’s take a better look.


Companies decide to hire in-house development when they are planning to develop their own product that will require ongoing maintenance and updates. This gives them access to a support team on-site, however, can be much more expensive than outsourcing.

When you are hiring in-house you have to consider aspects such as the time-consuming hiring process, providing a suitable workspace for your developer or team, training and later pay management, handling time off etc. In-house equals ongoing costs that are not present when outsourcing.


Freelance developers can be found through various portals, but they can be quite risky. Hiring a freelancer means you do not have control over the quality of your solution, the communication and availability can be limited while scaling means higher overall costs. What is more, you are entrusting your idea to a stranger, which puts you out for security risks.

Obviously, working with a freelancer brings cost benefits, but it is great only for short term commitments.

Outsourcing can be further divided into two categories:  team augmentation and hiring a dedicated development team. The first one is chosen by companies that already have a development team in-house, yet they lack specific skills or available resources. Team augmentation allows quick scaling with experienced engineers. Read more about staff augmentation in the post What Is Staff Augmentation.

On the other hand, hiring a fully-fledged development team is perfect when you need a self-managing team that can take over the project and handle it from start to finish. Outsourcing companies can also provide you with skilled designers and QA engineers, so you can focus on the business aspects of the web and mobile apps development. More about the topic in Outsourcing Trends In Software Development In 2020.

When discussing outsourcing it is worth mentioning the top locations where you can find experienced professionals, one of those being Poland. Polish developers are known for their high level of knowledge and code quality. Poland is still relatively cheap compared to other countries giving you the best value for money. What is more, they are reliable, have amazing communication skills and work culture.
