Why and When to Use Node.js For Your Projects

It can be difficult to build a tech stack that will enable you to create a robust, secure and robust digital solution. There are many programming languages and frameworks available that can impact the effectiveness of an app. It is important to select the right tech stack at the beginning of any app development project.

Node js is a popular choice for software developers who want to develop eCommerce websites, messaging services, streaming services, and other applications. Why is Node.js regarded as one of the most suitable environments for creating these types of apps? This article will discuss the reasons software developers choose Node.js to build their apps, and also explain other digital solutions Node.js can be used for.

What is Node.js?

Node.js goes beyond a framework. It’s an independent runtime that’s built on Chrome’s V8, a JavaScript-based engine. Node.js is a runtime environment that can execute application code regardless of the browser or operating system. Node.js can be run as a standalone application on any computer.

Other Node.js features are:

A single-threaded, non-blocking input/output

This operating model allows operations to be executed asynchronously. Instead of waiting for I/O operations, you can continue with other requests. Node.js solutions have higher productivity and can handle multiple clients requests more efficiently than apps that use a multi-threaded block model.

JavaScript for Back End Development

Software developers can use JavaScript to connect the back-end and front-end layers of an app. This allows them to do so with minimal merging errors. Software developers can also use a TypeScript package in Node.js to access this programming language.

A Package Manager for Node.js (npm)

The npm package manager contains over 600,000 free and open-source packages. These range from simple libraries to fully-featured frameworks that can greatly accelerate the development of applications. This package manager also helps software developers organize and better organize their code.

Sockets, Event-Driven Architecture

A socket mechanism allows a server or client to quickly exchange data and update other clients that are part of a group. This technology is used to build chat rooms and streaming services. The event-driven, non-blocking architecture makes it easy to develop applications quickly and efficiently using Node.js sockets.

Diverse Apps: A Variety of Tools Available

Node.js software allows developers to create cross-platform mobile apps for Android, iOS, web, and desktop. It is easy to trace the success of Node. js-based applications back to some of the most popular apps created with this framework. These include Mozilla, Groupon, and GoDaddy.

Advantages and Disadvantages of Node.js

Node.js is 6th in the StackOverflow survey of most used programming languages and frameworks. Node.js is a popular choice for web development projects because of several factors:

  • It is easy to learn
  • Solid community support
  • Scalability
  • Cost-effective
  • High performance
  • Cross-platform development

It is simple to learn, especially if you are familiar with JS. You will only need to know about the common APIs within it if you are familiar with its syntax. Node.js has a large developer community that supports and enhances it. You can also get help from experts around the globe to resolve any issues that might arise while using Node.js.

Developers can also scale their applications horizontally and vertically with Node.js by adding additional nodes. Multiple nodes can run simultaneously, and the environment will automatically balance the workload.

Node.js can also be used to create cross-platform web applications. This greatly reduces development time and costs. If Node.js developers are proficient in Vue.js, React.js, or Angular.js they can create both the front-end as well as the backend of an application.

Caching is one of Node.js’ key advantages. Caching is important for app performance. The server application executes all code when a request is made and retrieves data from the database. The server application uses a cache to return the information from memory, instead of running the code to process any subsequent requests.

These are just a few of the many benefits Node.js offers that have made it a popular tool for enterprise application development by giants like Linkedin and Uber, NASA, and Netflix. eBay. PayPal. Numerous businesses, from small-scale startups to large corporations, reap the many benefits of Node.js. Let’s take a look at the disadvantages.

  • API unstable
  • Node.js Asynchronous Programming
  • Library support is lacking
  • Lack of Node.js developers with experience

Many Node.js developers consider frequent API changes to be one of their greatest drawbacks.

There have been many changes made to Node.js API 18.2.0, and not all those changes are compatible with older versions. Developers must make modifications to the access code base every time a new version of Node.js API is released to maintain compatibility.

Node.js is slow when it comes to heavy CPU-based computing.

It can lead to “callback hell” if there are too many tasks waiting in the background. Callbacks are functions that run after the task is completed. Callbacks can become nested, which directly affects the performance and quality of the code. This is due to the synchronicity of Node.js.

It is difficult to use Node.js in simple programming tasks such as image processing, database operations, and XML parsing because there is not a robust and well-equipped library system.

The last and most important issue with Node.js development is the shortage of experienced, skilled developers. There is an increasing demand for Node.js programming, but a decreasing number of skilled developers. This makes it difficult for companies to find qualified Node.js developers. We have a Node.js team available to hire right away. We promise a quick team launch and ramp-up time, transparent work processes, and quick knowledge transfer.

What does Node.js do?

Node.js offers many advantages. It is lightweight, robust, easy to scale, and facilitates software development. What kind of software can Node.js allow developers to create? Let’s take a closer look at the places we can use Node.js.

Internet of Things (IoT)

The Internet of Things is a network of automated digital devices and computers that can communicate data without human intervention. This technology can be used in many different industries and cases. Some IoT examples include:

  • Agriculture automation;
  • Smart Cities and Homes
  • Retail analytics and logistics
  • Healthcare for self-monitoring
  • Connected cars and many other things

Node.js makes it easy to create an ecosystem of connected devices. IoT devices produce a lot of requests that need to be processed quickly. Node.js can handle these requests efficiently without any downtime. Node.js servers can store large amounts of data generated by IoT devices. Node.js does not load much device memory so it can be integrated to single-board controllers to create digital devices for the IoT ecosystem.

Real-time apps

Node.js is perfect for creating social networking apps, streaming and collaboration services, collaborative tools, interactive websites, instant messaging, instant messengers, and other types of applications. These apps all have one thing in common: they can send live text, audio, and video data in groups, or through face-to-face interaction.

Node.js can process high-traffic real-time flows and maintain data streaming at a high level with its event-driven structure. Users don’t feel any delays in data exchange or updating.

Single-Page Applications

A single-page app (SPA) is a page that displays dynamically changing data on a browser. These apps don’t have to load the entire page to display the data. SPAs load faster than regular websites, and can significantly improve the user experience when you have a slow internet connection.

Node.js is a great choice for building SPAs because it can handle heavy I/O workloads, and works well with asynchronous calling. SPAs can be built using JavaScript, which is the primary programming language of the Node.js framework.

Apps with Microservices Architecture

Node.js can easily be used to build any application that is based on microservice architecture. This type of architecture uses small modules that have very specific functionalities and are combined into an application. Microservices architecture is a popular way for software developers to create large, complex enterprise applications. This allows apps to be scaled easily and is easy to modify.

Software developers can use native Node.js frameworks like Express.js or Koa.js to build microservices architecture. They also have access to a Docker platform. These tools enable developers to quickly create robust apps and release them to the marketplace.

The Main Trends in Node.js that You Should Watch In 2022

Node.js is a rapidly evolving environment that grows every year. It allows businesses to realize their full potential by providing them with the most recent technologies to create their digital solutions. These are the top Node.js trends for 2022.


GraphQL allows you to request data in JSON format directly from the server using a query language. The best thing about GraphQL? It allows users to request specific data from the server. This avoids data over-fetching and under-fetching. This allows for faster data loading and a hierarchical, logical, and strongly-typed language structure.

According to the State of JS, GraphQL was rated as the most exciting, satisfying, and widely used technology for managing data layers within apps.

MEAN and MERN Stacks

MEAN (MongoDB Express.js Angular, Node.js), and MERN (MongoDB Express.js Angular Node.js), will continue to hold their top positions in the field of app development in 2022.

These technologies can be used to build dynamic, single-page web apps. These stacks are used in large tech companies like Netflix, Uber Eats, Instagram, Accenture, Onkore, Inc., Inc., and many others.

Serverless Architecture

Serverless architecture is the best choice for businesses that don’t need to rely on hardware or spend hours configuring servers. This allows platform providers like AWS Lambda or Azure to handle all software and hardware issues, while developers can focus on the core features of the app.

Node.js can be easily integrated into cloud platforms using serverless architecture services. Software developers can significantly reduce development costs, ensure high-quality code, and provide great flexibility for their apps.

Why use Node.js The Main Points to Consider

Node.js is highly regarded by software developers as it offers the best tools to develop various applications. However, Node.js is just like any other platform for development. It has its pros and cons.

This is a list of common situations you should consider when developing apps in this powerful software environment.

Node.js is the best tool for building:

  • Complex, enterprise-level apps that use microservices architecture.
  • Live to the stream of apps and real-time applications
  • Collaboration tools for teamwork
  • Apps that rely heavily on scaling with high traffic and an ever-growing number of users rely heavily on this.
  • You might also consider other Node.js solutions if you are looking to create something:
  • Apps that require heavy computing on the server side – Node.js used only one CPU core. This way, heavy computing could result in blocking all I/O requests.
  • CRUD apps – These apps get data directly from the server, without any APIs. Therefore, Node.js functionality may be too restrictive for these apps.
  • Monolithic architecture – Although it is possible to create a monolithic structure with Node.js it will be difficult to scale due to Node.js’s single-threaded events loop, slow start-up time, and redeployment for the entire application with every update.

If Node.js is not the right tool for your digital project, there are other frameworks like Ruby on Rails or Symfony on PHP.


Node.js, a popular back-end development platform, allows for the creation of flexible applications for large companies, SMEs, as well as start-ups. This robust solution provides a wide range of tools to create real-time apps, IoT applications, apps with microservices, serverless architecture, and many other types.
