Node.js is a back-end, server-side platform based on JavaScript. It was developed in 2009 and is a popular framework for coding scalable and lighting-fast network applications. It comes with a non-blocking, event-driven I/O model – ensuring the framework’s efficiency and lightweight nature and making it perfect for real-time data-intensive applications.
Developers frequently use Node.js for developing networking and server-side applications. Any application built on this framework is written in JavaScript and compatible with Linux, Microsoft Windows, and OS X.
Also, Node.js comes with a rich library of different JavaScript modules – significantly streamlining the process of developing web apps on Node.js.
Node.js is a perfect back-end framework for real-time applications. It can provide performance and speed, and one of its textbook use cases is various chat (real-time messaging) applications and functions.
On top of that, Node.js is often used for IoT applications because of its ability to deal with huge data flows. Node.js is famously easy to integrate with WebSockets, MQTT, and other IoT protocols.
Also, the Node Package Manager comes with plenty of useful IoT modules that make developing software for embedded systems far easier – even Microsoft uses this framework for their IoT work.
Furthermore, Node.js’s ability to efficiently process real-time data flows makes it a perfect candidate for developing collaborative tools. Various online collaboration platforms and project management software like Trello were built on Node.js – or at least their back ends were.
Generally, any data streaming application would be well-served with Node.js because it makes transferring vast amounts of data simple; particularly critical for video and audio streaming apps. That’s why Netflix uses Node.js as well.
Finally, any projects that consider scalability important from day one will find Node.js to be a fine choice.

We don’t charge anything when you post a freelance hiring request for Node.js developers! You’ll have the chance to determine what the budget for your project is when you post the request.

On a daily basis, Node.js developers maintain and deploy various network applications. They also provide support to front-end devs by helping them integrate web-based apps.
In practice, this includes maintaining and developing all necessary server-side components and ensuring sufficient responsiveness to all front-end requests. That process involves collaboration with front-end devs, implementing critical storage solutions, data protection measures, and efficient security protocols.
To do that, a freelance Node.js developer must have a relevant degree in fields like information technology, computer science, or similar – along with a minimum of two years of experience working in Node.js.
Some knowledge of front-end frameworks and languages is also beneficial, such as CSS3 and HTML5. Of course, a general aptitude for problem-solving and analysis is necessary for any decent Node.js programmer.
