Having worked on numerous Node.js projects so far, we can easily point out its advantages. 

Among the most important are:

  • Creating the backend and frontend of the applications using the same language (this is possible thanks to JavaScript engine sharing of models and functions ensuring a more consistent logic).
  • Efficient handling of multiple requests simultaneously.
  • Scalability - the ability to handle larger loads without having to redesign the application.
  • High efficiency - Node.js applications use fewer system resources and run faster than applications based on other programming languages.
  • Costs and time savings - comparing to other programming languages, developers can create applications much faster and for a lower price.
  • Wide usage in various fields and industries.
  • An extensive ecosystem of tools, libraries and frameworks that streamline the application development process.

What types of projects are best suited to Node.js?

(based on Polcode's experience)



Building microservices

This is where individual components of the application work independently. Thanks to Node.js lightness and asynchrony, applications can efficiently handle large number of requests.


Backend of mobile apps

Node.js works well as an API server for mobile applications, in which database operations, business logic, and communication with other services are supported.



Simple prototype projects and MVP

For projects with small scopes and limited resources, Node.js can be a perfect choice thanks to fast development times and low infrastructure overheads.



Apps based on RESTful API

Great for creating API servers that provide interfaces for other applications.


Real-time applications

Such as chats, multiplayer games, online auctions, and monitoring systems.



Desktop applications

Thanks to tools such as Electron, Node.js can be used to create desktop applications using web technologies.



Streaming services

The technology is highly suitable for creating applications that use streaming data.


Web apps and eCommerce

Node.js can handle large amounts of data quickly and easily. With its scalability and speed, you will be sure to benefit from faster response times, better performance, and a smoother experience for your eCommerce customers. 


Websites and Single Page Applications (SPA)

Node.js uses JavaScript on both the server and client sides, allowing developers to use the same language throughout the entire application. It is the best choice for SPA development because of its asynchronous backend data flow quality.
