Frequently asked questions

If any of the questions haven’t been covered yet, in this section, you may probably find the answers.

What is Node.js mostly used for?
icon icon

Node.js is useful for creating real-time applications that produce a lot of I/O activities, which in turn means apps that get a lot of traffic.

These consist of:


  • Game apps;

  • Project management tools and social networking tools;

  • Applications for audio and video broadcasting;

  • Message boards;

  • IoT gadgets and software;

What are some benefits of Node.js?
icon icon
  • Since Node.js is based on Google Chrome’s V8 JavaScript Engine, the library executes code incredibly quickly.

  • Due to its system, which enables the server to reply without delay, it is very scalable.

  • A large open-source community that uses Node.js has contributed to the creation of numerous top-notch modules that provide Node.js applications with new functionality.

  • Applications written in Node.js output the data in chunks without ever buffering it.

  • One of the most widely used programming languages for front-end development is JavaScript, and almost every front-end developer is familiar with it. Therefore, switching to Node.js for the back end is significantly simpler for developers. Even a novice JavaScript coder may learn and use it with minimal time and effort.

  • With Node.js, you can create anything from the ground up and customize every little element. It can perform fundamental tasks but only provides the base essentials upon installation, enabling you to add functionality with fewer limitations.

What are some disadvantages of Node.js?
icon icon
  • The lack of consistency in Node.js is one of its main drawbacks. The API for Node.js is constantly evolving, and these changes are usually backward-incompatible. When this occurs, developers must update the current code base to conform to the most recent Node.js API release.

  • Node.js is un-opinionated. This might provide you freedom, but it can also slow down your work by decreasing productivity.

  • It is not appropriate for carrying out time-consuming calculations. Incoming requests are delayed by complicated calculations, which might reduce performance. Node.js is perfect for complicated projects, but it might not work for software that needs a lot of processing power.

Why Node.js is single-threaded?
icon icon
To enable async processing, Node.js employs a single-threaded paradigm. An application can run more efficiently and scale better when using async processing. As a result, rather than using a thread-based solution, Node.js leverages a single-threaded model approach.
How can I scale the Node.js application?
icon icon
The Node.js application has both horizontal and vertical scaling options. Also, it suggests that you must distribute the traffic among many CPU cores and run numerous instances of your software on a single system. Besides, Node.js offers a cluster module, which is quite useful. When it comes to horizontal scaling, it functions just like any other standard back-end program.
What are the different streams in Node.js?
icon icon

Streams are primarily those elements that provide both reading and writing of data to and from a destination. There are four primary categories of streams, as follows:


  • Easily readable: this stream promotes a reading operation.

  • Writable: it facilitates the writing process.

  • Duplex: the stream enables reading and writing.

  • Transform: this type of duplex operation performs computations while taking the input into account.

Is Node good for prototyping and MVPs?
icon icon
A large collection of modules included with Node.js allows developers to experiment and create MVPs rather quickly. The efficiency and scalability of Node are an advantage in case the program is planned to be scaled up or expanded in the future.
