Scalability is exceptional:

  • Node JS exhibits high scalability, owing to its event-based mechanism, enabling the server to deliver a non-blocking response.
  • Node JS is platform-agnostic. It supports various operating systems such as Windows, Mac OS X, and Linux.

Ideal for real-time applications:

  • Node JS is perfectly fit for developing real-time applications like games and chat services.
  • It also comes in handy for applications that necessitate an events server.

High efficiency:

  • Node JS leverages single-threaded JavaScript runtime to deliver built-in network applications.

When is Node JS framework the best fit?

Backend for Social Media Networking

Node.js’s V8 engine is widely acclaimed for its rapid routing capabilities and robust authentication security protocols, making it the perfect choice to power dependable, high-traffic websites such as Medium and LinkedIn.

Single-Page Application (SPA) Development

Node.js is a top-notch platform for building single-page applications that offer a desktop-like experience, making it the perfect fit for creating social networking websites, dynamic web pages, and email solutions. By utilising Node.js, developers can design an application that can be accessed, upgraded, and maintained from one page, streamlining the process of creating and managing complicated web applications. Moreover, Node.js offers a plethora of features and tools that enable developers to quickly establish robust and engaging applications with minimal effort. Its backend’s asynchronous data flow capability also makes Node JS the ultimate choice for Single-Page Application (SPA) development.


Node.js presents an optimal solution for building advanced chatbot and chat system applications due to its capacity to handle multi-user applications, voluminous data, and high traffic across all gadgets. Node.js ensures compatibility with all paradigms, making sure your chatbot application is accessible to users regardless of the device they use. With its expansive capabilities, Node.js is an ideal fit for any chatbot application. Furthermore, Node JS simplifies the process of implementing server-side event loops and push notifications, which are indispensable components of instant messaging and real-time applications.

Data Streaming

Node JS framework’s exceptional performance in handling file processing, encoding, and uploading makes it particularly beneficial for data streaming, making it the ideal choice for applications that require real-time data streaming, Node JS framework is unrivalled in achieving these tasks promptly and efficiently. For example, Netflix has adopted the Node JS framework, enabling them to offer streaming services to over 120 million subscribers in 190 nations, totalling over 100 million hours.

Internet of Things (IoT) Application Development

The Internet of Things (IoT) has gained immense popularity in the past decade, and consequently, the Node.js framework has emerged as one of the most desirable solutions for businesses to create both public and private IoT solutions. This framework provides the flexibility of employing a scalable, open-source JavaScript runtime environment, which can be utilised to develop a wide range of applications.
Node JS’s event-driven server architecture and its ability to manage heavy I/O operations asynchronously in IoT networks are some of the key benefits of using Node JS’s event-driven server. Furthermore, the use of write and readable channels and streams is one of the reasons why the Node JS framework is the most appropriate platform for IoT application development.

Well-Known Companies That Utilise the Node JS Framework

Although relatively new compared to other programming languages, the Node JS framework has gained significant momentum among Fortune 500 corporations. The popularity of this framework is due to its scalability, top-notch security, and extensive libraries, making it the preferred choice over other frameworks.

These are some of the popular companies that actively employ the Node JS framework:

  1. LinkedIn
  2. Netflix
  3. Uber
  4. Trello
  5. PayPal
  6. NASA

When is the Node JS framework not suitable?

It is essential to weigh the pros and cons of each technology when researching the available options. With several alternatives to choose from, it is important to critically evaluate each one to determine which one best suits your needs. By dedicating time and effort to assessing the advantages and disadvantages of each technology, you can make an informed decision and select the most appropriate solution.

Nonetheless, if you are considering building any of the following apps, you should rethink your decision to use Node JS.

Beta Testing of a Relational Database

Leveraging the power of Node.js and Express.js, it is possible to develop standard web or mobile applications on the server-side. However, any heavy computations that consume a large amount of CPU power can render the Node.js framework non-responsive, which can adversely affect application performance.
It is advisable to use other tools for relational operations since the Node JS Relational DB tool is still in beta testing.

The Server’s Processing Requires Significant Resources

Node.js may not be the best choice for intensive server-side computing. Its non-blocking I/O node model and event-driven architecture are not ideal for conducting large-scale operations.

Computation-Intensive Processes

As Node JS is single-threaded, it may not be the best fit for your web applications. For instance, if the server has to carry out a large computation, it could cause a delay in performance.

Flaws in the Tool

The Node JS framework has proved to be exceptional in a wide range of applications and situations.
However, despite the support of npm modules and libraries by an active Node community, several users have raised concerns about bugs, inferior quality, incomplete modules, and insufficient documentation.
Even though your team of seasoned Node.js developers is familiar with Node.js, it is crucial to exercise caution when picking npm modules and libraries for your project. This will guarantee that the correct selections are made, and the project is executed successfully and promptly.
