Node.js has a widespread following heading toward 2021. All thanks to its large ecosystem of open-source libraries and Node.js frameworks. In fact, last year’s Stackoverflow Developers Survey ranked it first over similar technologies. 

Node.js is light, efficient, and highly scalable, which makes companies big and small choose it for application development. Plus, it offers an easier development process, reusable code, great concurrent request handling, and fast code execution. Not to mention Node.js can boast of a vast talent pool.

Since Node.js is simple to use, fast to deploy, highly scalable, and has a large active community, no wonder it’s used for developing real-time web applications, multiplayer games, and collaboration tools. It’s also the go-to technology for building streaming, messaging, and social media apps.

Node.js is a runtime environment. It is lightweight, efficient, and capable of launching both backend and frontend JavaScript applications.

Node.js has superior processing power compared to Python, making it ideal for developing data-intensive and real-time applications like messaging apps and e-Commerce websites. 

The list of Node.js frameworks is extensive, but as a professional Node.js web development company, we recommend Express.js (used for creating restful APIs that communicate with the frontend-side applications), Koa (a lightweight alternative to Express.js with out of the box async function support), and Hapi.js (known for its rich security aspects and stability).

Node.js developers build, deploy, and maintain network applications. Our engineers develop backend components and support frontend developers by integrating web-based applications and APIs.

Node.js developers remain in demand mainly because of the popularity of the products built in this environment.

Certainly. Along with Node.js development services provided by our team, you can hire an individual or a full team of developers with a project manager that will see the project through its completion. If you need quality assurance engineers, business analysts, designers, or architects, we can provide them as well.
