Many companies, including tech giants like Netflix, PayPal, and LinkedIn, are hiring Node.js developer teams for Node's outstanding performance. It multitasks well, is light on the server, and runs on V8, a fast engine for chromium browsers like Google.

Node.js is a backend solution, a runtime environment that allows JavaScript to be executed on the server. Ryan Dahl created it in 2009, aiming to develop an architecture that would enable the creation of complicated programs through basic ones.

Choosing a backend technology for your web application is not a walk in the park, but if you want to focus on scalability and performance while saving on development costs, then hiring a Node.js developer might just be the option for you. Come along and find what to look out for when you hire a Node.js developer!

What is Node.js?

As we already covered in our previous blog post about Node.js, this open-source environment is used for developing and running io-intensive web applications. It is the perfect ecossystem for data-intensive applications because it uses an asynchronous, event-driven, single-threaded model. Take a look here at what exactly Node.js is, how it is used and when you should or should not implement it in your project idea.

What does a Node.js Developer do?

A common question hirees might have is what Node.js roles and responsabilities are. Simply put, a Node.js developer is responsible for deploying and managing network applications in JavaScript or its variants, such as IcedCoffeeScript and CoffeeScript. They control data exchange between servers and users, develop backend components, and connect applications with third-party web services. They also support front-end developers by integrating web-based applications.

Node.js Developer roles and responsibilities

To ensure you hire a Node.js developer that is a good fit, he must have extensive knowledge of Node.js-based services. An accomplished Node.js developer will be someone whose expertise results in consistent, swift, and secure data exchange. Here are the full responsibilities and must-have skills a Node.js Developer should have:

  • Deploy and manage all server-side network elements.
  • Ensure optimal responsiveness to front-end requests and central database performance.
  • Work side-by-side with front-end developers on integrating components.
  • Design customer-facing UI and backend services for business operations galore.
  • Develop high-performance applications by writing testable, reusable, and efficient code.
  • Enforce adequate safety protocols, data protection measures, and storage solutions.
  • Execute tests to fix deficiencies, and provide technical support.
  • Report operations, including database schemas.
  • Advise, recommend and execute improvements to processes and technologies.
  • Keep up-to-date about advancements regarding Node.js development and technologies alike in general.

What should a Node JS developer know?

Besides the above-mentioned must-have skills, a Node.js Developer should also understand how the technology works overall within various scenarios.

1. Expertise in Node.js Development

Created in 2009, Node.js has been enhanced by several contributors as an open-source platform ever since. Its library contains many Node.js frameworks, IDEs, and tools.

A web developer should have at least three years of background working with Node.js and significantly notable Node.js projects under their belt. It is also preferred if the developer has regularly contributed to bug fixes and patches to the Node.js community.

Their active engagement and contributions to Node.js projects reveal a thorough knowledge of Node.js internals- this also demonstrates that they are excellent team players with a strong interest in bespoke software and web application development.

2. Understand front-end technologies

Front-end development is what end users see when they use an application. Hence, developers must be familiar with front-end architecture and development, such as HTML5 and CSS.

3. Solid knowledge of Node.js frameworks

Frameworks are essential to the Node.js ecosystem because they extend Node.js' features. While there are a variety of Node.js frameworks to pick from, the Node.js developer team you hire must be familiar with them all.

Express is the basic framework that all Node.js developers and programmers should be familiar with, according to most Node.js developers.

Other frameworks that support Express: Koa.js, Hapi, and Total.js.
Full-stack MVC frameworks: StrongLoop, Sinatra, Keystone.js, Rails, Meteor, ActionHero, and Derby are amongst them.

4. Proficiency in RESTful APIs and API communications

Every Node.js developer must be able to infer existing API codes and apply them to the projects. Dealing with interactions across different applications is a must while having an extensive understanding on creating custom ReSTful APIs.

5. Asynchronous programming

Node.js is a non-blocking, asynchronous programming technology, which means that the time for requests to be processed is significantly low. Two or more functions can run simultaneously, allowing developers to be more productive and efficient.

However, because asynchronous programming is still a relatively new technology, there are nuances that every developer should be aware of. Developers will be unable to take the necessary steps unless they fully grasp the workarounds.

6. Database schema for business processes

One of the abilities required to develop successful apps is database management. Database schemas that describe and support business operations should be created by Node.js developers and integrated into a single system - this is crucial for setting apps that may effectively service any organization's business operations.

7. Knowledge in user authentication, authorization, and data protection

User authentication and authorization across many systems, servers, and settings should be familiar to a Node.js developer - this aids in the development of extremely secure online apps.

Security has also become a more complicated issue in today's digital age. Implementing data protection solutions in online programs is a high priority, as it reduces the risk of hacking, security breaches, and data theft.

8. Write efficient code

Codes must be object-oriented in order to be readable. Some web developers and programmers write code that only they understand, making it difficult for other developers on the team to understand and update or alter their work.

To ensure consistency of work, make sure the Node.js developer you're hiring follows industry best practices. Developers must work well with others. If they do not create code effectively, it may impede team productivity and success of the projects.

9. Problem-solving skills

Error management is an important aspect of creating reliable software and applications. Node.js developers must understand when to crash, record an error, keep going, and when to try again.

Any Node.js developer should possess basic problem-solving abilities include troubleshooting and syntax manipulation.

Advantages of Node.js for your business

According to Stack Overflow Research Node.js is broadly used for back-end development and is a worldwide leader among frameworks.

Besides that, web development using Node.js is a breakthrough technology with unique characteristics, being one of the most efficient cross-platform JavaScript environments for developing strong and effective REST APIs, mobile apps, and web apps. So why is Node.js a good solution for your web app development?

- Easy & simple hosting

Node.js platform constantly implements new features and functions that benefit individuals who provide PaaS (platform-as-a-service) services to minimize waiting times; this is one of the main reasons open-source software development agencies pick Node.js for web development.

- Effortless sharing

The ease of sharing the NPM (Node Package Manager) is the key reason many web development firms prefer Node.js over other frameworks. You may quickly share anything with Node.js, which increases the pace of other development operations. Many Node.js developers, for example, utilize NPM to share resources when working on a team project. Plus, NPM allows them to manage and deploy code effortlessly.

- It is cost-effective

Organizations that use Node.js now use less computational power to host web apps. What's more, it is faster than compared to other frameworks.

- Real-time applications

Node.js enables you to create high-performance apps with fast results. Node.js-built web apps allow you to perform several activities simultaneously. It has a single-threaded and event-driven design that enables you to process multiple concurrent requests without affecting RAM.

- Allows single codebase

While many frameworks employ different programming languages for both client-side and server-side web development, It stands out because it allows developers to build code for complicated web app development projects using a single codebase. Given that several frameworks integrate several languages, businesses must hire developers fluent in more than one language.

- SEO-friendly

SEO plays an important role in web app development. Sites benefit from improved visibility thanks to Node.js backend rendering; this occurs for search engines to efficiently optimize the React Projects. Because Node.js provides great speed and performance, it is picked as the ideal framework for improving SEO techniques.

- Easy deployment of web applications

Node.js-based web apps are easy to deploy. This framework helps developers complete and test all aspects of a web application quickly. This framework is valuable to many PWA development organizations since it speeds up the final deployment of the web apps.
