A website or application without back-end development can be compared to a new car without an engine – looks beautiful yet won’t start. No wonder developers use each and every tool that helps them create applications that run seamlessly and please their users.

In this article, we’re going to stop on popular and widely used back-end development platform — Node.js . Here you will find all the details regarding Node.js developer responsibilities, skills, hourly rates, and other information you may find useful. Additionally, we’ve listed hiring options and Node.js interview questions to enrich this article and make it as useful as it can be.

Node.js Developer Roles and Responsibilities

First of all, let’s take a look at the main roles of NodeJS developers and find out what they are usually responsible for.

Roles of Node.js Developers

The primary focus of Node.js specialist remains the management of data interchange between users and the server. Besides, developers work on such issues as creating logic behind applications, establishing close to perfect performance and making sure that user requests are thoroughly processed by the system.

Node.js development services include both front-end and back-end. So even if you’re going to hire a back-end developer proficient with Node.js, they should have a basic understanding of the user-facing part of application and be ready to work with front-end elements created by their colleagues.

Additionally, as third-party tools are used during any app development, Node.js roles include integration various tools into applications.

Node.js Developers Responsibilities

Software developers always have a wide range of responsibilities and Node.js devs are no different.

This way, tasks Node.js specialists are responsible for include:

  • Adhering to Agile methods
  • Clear code writing
  • Front-end development
  • Security implementation
  • Detecting performance issues
  • APIs integration
  • Database configuration
  • Staying up-to-date

Main responsibilities of Node.js developers

Now let’s review the aforementioned responsibilities in details.

Working with Agile methods

Agile approach is widely used in IT sphere today due to its democratic ways of handling the development. Therefore, Node.js developers should be familiar with Agile development methods to follow them during product development. The methodology helps to organize planning, design, and testing during the development lifecycle which greatly simplifies the whole process.

Front-end provision

Although Node.js is considered to be a back-end technology, front-end developers deal with it pretty often. Moreover, it’s hard to imagine a project created without Node.js tools. The platform is used for NPM scripts, creating Gulp tasks, web pack configuration, etc. By the way, full stack Node.js developer rates is usually higher than the pay of back-end specialists.

Writing a clear code

Creating an understandable code is what defines seniors among junior Node.js developers. The code written by a professional is reusable, laconic and easy-readable. Additionally, senior developers have a good practice of object-oriented programming, DRY (Don’t Repeat Yourself) principles, know main design patterns and are willing to follow the uniform code format. By using these means, the developer will greatly help their colleagues to understand what is actually going on and prevent important parts of the code from being removed.

Working on security features

Security these days is the top priority and thus something you don’t want developers to overlook. There are quite a few security options Node.js developers should be aware of, for example, HTTP response adjustment, limiting concurrent requests, avoiding module loading, etc. In addition, developers have to pay special attention to sensitive data such as payment details and be familiar with GDPR terms. All that will help developers to secure the product and reduce the number of hacking attempts, negating their results.

Bugs detection

We’ve already mentioned that writing clear code is extremely important, and here’s another explanation why. After the job of Node.js developer is done, QA team performs a thorough check, detecting bugs and other imperfections. Thus, if any issue appears during the testing process, developers should fix it in a timely fashion, no matter if the code was written by them or another dev team. In addition, Node.js specialists run autotests during test-driven and behavior-driven development processes as well as perform unit testing.

Third-party services integration

Complex applications or websites rarely run without any third-party services, for instance, payment systems like PayPal, Stripe or Braintree. Node.js is great for integrating complex environments as it allows to simplify the process due to the number of already made modules created by other developers. Modules reduce development time and, respectively, its cost. This is beneficial for both devs and product owners – after all, the main goal of Node.js dev hire is finding a person that can make a website or application run properly with minimum code lines.

Working with databases

If you’re going to deliver personalized content it’s necessary to store the data somewhere. By using Node.js in combination with databases, developers configure data storing process in applications. Usually, databases have drivers for Node.js and libraries in NPM which speeds the configuration process up. The most popular database management system for Node.js is MongoDB which allows working with the database, receive and add data to it.

Keeping up with technology

Node.js updates are being actively developed and released a few times a year. Thus, the development team should be ready to switch to the latest version with a lot of improvements, security updates, and new features. By the way, as Node.js platform is used for both front-end and back-end development, it’s vital for the specialist to get acquainted with other Node.js developer tools.

Node.js Developer Skills

As always, in order to fill the position, a potential Node.js developer should have specific skills and be competent in the field. According to the skills, we can define three levels of developers: junior, middle and senior.

Some product owners may want to hire senior Node.js developers in order to make sure that their projects are in good hands. Still, in some cases, middle devs may show the same good results. So let’s take a look at the main skills of Node.js specialists by levels to find out which one suits you best.

Skills of a junior Node.js developer include:

  • Understanding of Node.js basics (Event Loop, libuv, asynchronous programming, etc.)
  • JavaScript knowledge
  • Knowledge of popular Node.js frameworks (Express.js)
  • Database basics (relational or non-relational databases)

Hiring Options

When it comes to web development services, there are three popular hiring options on the IT market. To hire the best specialists you should rather prepare a list of your requirements and find out what option matches it most.

So, do freelancers with a decent knowledge of Node.js and hourly rate you can afford are the best? Are you considering in-house employees? Or, maybe, interested in outsourcing software developers? Let’s review all three in details to find out.

Freelancers

Hiring a freelancer often seems to be the most attractive option with a number of resources to look through. However, there always is a catch. Freelancers work for themselves and may indeed be experienced specialists with a number of projects under the belt, good rates, and nice reviews. Still, you cannot know for sure that all the information provided is valid. We suggest considering this option only in case you need to make some minor changes in a website or app, or someone to work on a simple short-term project.

By the way, it’s definitely worth paying attention to the fact that you cannot hire one Node.js developer for delivering a feature-rich product from scratch. Most probably, you will also need a team of front-end devs, QA testers, designers, etc. It may be extremely hard to remotely cooperate with a full team.

Pros

  • Cheap
  • Wide range of specialists

Cons

  • Deadlines may not be met
  • Developers may disappear anytime
  • No contract signed
  • Possible language barrier
  • Different time zones
  • Management complexity

In case you’re sure that freelance developer is exactly what you need, we suggest using the following resources to hire one:

In-house developers

In-house specialists will be working from your office and, prior to that, should ace the interview. Office employees are great for delivering a specific project you put high stakes at – that means providing full support, maintenance, and updates when required. This approach allows you to control each and every member of the team, monitor their performance and assign specific tasks to certain people.

Although in-house approach is what we see in everyday life, it’s considered to be the most expensive option due to monthly wages, rent payment, a working place you have to deliver as well as many other expected or unexpected costs.

Pros

  • Developers can be accessed anytime
  • Effective collaboration
  • Full control of the development process
  • Same schedule, no communication issues
  • Great for long-term projects

Cons

  • Undergoing the interviewing process
  • Monthly wages regardless of the actual contribution
  • Additional expenses: sick leaves, vacations, paid days off
  • Office rent and taxes
  • Software and hardware expenses

In case in-house option works for you, we suggest checking such resources as:

Outsourcing companies

The last but not least option is working with an outsourcing team of Node.js developers from another country. This approach works for both small and large projects with any budget as the total cost is usually much lower than Node.js development done by of in-house employees.

Outsourcing teams are qualified and have all the required software and hardware – all they need is a thorough description of your project and your willingness to cooperate.

In addition, if you need just one Node.js specialist for completing a task, you can always hire them from the company and not to worry about failed deadlines or no documentation signed. Most outsourcing companies sign contracts and watch over their reputation by monitoring customers’ feedback.

Pros

  • Reduced production cost
  • No additional expenses you have to bear
  • Each aspect can be discussed with the product manager
  • General team experience and quality work

Cons

  • Possible language barrier and different time zones

However, the cons of working with outsourcing developers are easy to manage. Companies often assign dedicated team managers proficient in English to projects to establish the cooperation process, and they are available almost anytime.
