12 Types of Node.js Applications with Examples

In this article, we will understand why popular internet platforms choose Node.js as a backend for their applications. You will learn about 12 types of Node.js based applications using examples of known resources.

Node.js is a free, open-source platform that runs on JavaScript and allows you to create your projects quickly and efficiently. Node.js applications are very fast in terms of performance.

Why use Node.js?

Every developer wants to introduce an application that allows the user to take advantage of many features at once.

Node.js provides developers with such facilities – one can create highly scalable apps which may allow multiple requests from the user at once. It shows a one-way process without showing a new thread on each user request.

Additionally, it executes input/output operations by allowing access to the database. Node.js forms backend data for web applications to confirm better support for synchronized communication at a time.

Features of Node.js

  • JavaScript Framework
  • The Server-side is based on Google Chrome’s V8 Engine
  • Rich library of modules available for developers
  • Non-blocking, I/O
  • Lightweight
  • Converts JavaScript code into machine code quickly
  • Jam-packed module ecosystem containing the entire necessary database you need
  • Utilizes npm package manager
  • Asynchronous and event-driven nature
  • Full-stack development language.

Let’s figure out what types of applications can be created using Node.js.


Best known Social Media apps and platforms such as Twitter, LinkedIn are also written in Node.js using JavaScript Framework.  

Networking apps and platforms need to be efficient and reliable. They contain sensitive information of the user like contact number, email address and debit card details in case of any transaction. 

The system needs to be updated as the network grows because the demand of the user increases. 

Hence, Node.js provides a fair chance with both horizontally (Addition of new nodes in the system) and vertically (up-gradation of existing notes by adding additional resources). 


LinkedIn was launched in 2002. Now the number of its active users is almost 700 million. Initially, developers used Ruby on Rails process-based system to build the app. As the company was expanding, so up-gradation was required.

It is functional on both Android and Apple devices. It is used to communicate between technicians and users. You can easily carry out repairs remotely courtesy of this application.


IoT Node.js projects refer to physical tools that share and exchange information via the Internet, such as beacons and sensors. 

The data displayed by the application comes from servers. These servers receive data from IoT devices built by using Node.js. IoT system is not that simple because the system consists of multiple numbers of devices.

 Node.js database servers provide the most appropriate solution for developing private and public internet of things systems. 

Today the human race is getting many benefits from these IoT devices as they have opened the magical door of opportunity for the technology world. Here is an example of some IoT tools.

Internet of Things Project

Internet of Things Node.js project allows you to compare the performance of equipment to its standard performance. This helps us in understanding and identifying anomalies. 

The technology used in this project is Node.js. The main aim of this project is to enhance maintenance frequency, improving process quality to avoid device failure. 

This helps the user to identify abnormal behaviour of the machine before any incident happens.


Node.js microservices examples are Utilitium and ServiceDoc. These applications are created by gathering separate modules and each module plays its role in the proper functioning of the app. 

Modules are developed and tested continuously to form a complete application. This architecture type helps in the formation of a large enterprise. 

Development teams of these apps are distributed and vast geographically. Node.js microservice architecture projects are composed of Express and Koa framework.

But with the advancement of time and the modern needs of the user, developers tried to write it in Node.js backend. 

Switching it to Node.js from Java Application resulted in remarkable results. Now it has fewer coding lines. That is why it works faster. Page loading time is 200ms faster as compared to the previous version. 


One of the Node.js e-commerce platforms is eBay. E-commerce apps need to be highly functional. 

They must bear heavy loads. As many users will be searching, shopping, making orders or doing transactions. Node.js framework is perfect for handling large and complex websites because of its event-based non-blocking technology.


eBay was launched in 1995. Now it has almost 200 million active users. Initially, it was based on java and JVM technology stack. The entire workload was revolving around it.
