Cases Where Node.js Development Is Appropriate

Choosing the right backend technology is an essential part of the process when creating new software or applications. Historically, JavaScript developers have had to find an alternative for server-side support. Fortunately, Node.js has made it possible for developers to create applications using the full range of functions of JavaScript.

Despite the many benefits of Node.js development, it is not always the most suitable choice. If you are unsure whether Node.js is the right technology for your project, whether you are working with an internal team or outsourcing to a nearshore development company such as Works, then the following facts may help you make an informed decision.

Node.js: What Is It?

Node.js is a free, open-source and cross-platform runtime environment written in JavaScript which enables the server-side execution of JavaScript code. Since its initial release in 2009, Node.js has become increasingly popular. Additionally, Node.js offers an impressive array of libraries and tools, in addition to its core components.


This is because Node.js is built on top of the Google Chrome V8 JavaScript engine, which allows for quick and lightweight code execution.

Architecture based on events

Node.js does not wait for a request to be completed before starting another one, nor does it create a new thread for each request. Rather, it utilises a single thread to process multiple requests simultaneously. If an API request does not yield any data, the server can move on to the next available API. The events module helps the server to obtain a response from the previous API.

Tracking Node Packages

Rather than utilising Structured Query Language (SQL), the Node.js environment adopts a document-based database approach. Benefits of this approach include the ability to quickly and easily import features for your application from the world’s largest open-source library registry, maintained by the Node Package Manager (NPM). Using the NPM enables you to save both time and effort during the development of your application, due to its ability to facilitate code sharing and reusability.

The Benefits of Using Node.js for Coding

The primary aim of Node.js development is to create a platform that is easy to use to build dynamic, high-traffic websites and applications that are responsive and are able to handle large user loads. Developing with Node.js has a plethora of advantages, including:

  • Conveniently Simple to Pick up: For developers already familiar with JavaScript, getting started with Node.js is incredibly straightforward and requires very little learning. The transition to coding with Node.js should be relatively effortless for those who have an existing knowledge of JavaScript.
  • Promising in Efficiency and scalability: When utilising Node.js’s microservices capabilities, code for an application’s individual components can be divided into separate services. This approach simplifies the scaling of programmes and the incorporation of additional features. By using JavaScript for both the front end and the back end, a full stack application can be produced using just one language. In addition to facilitating the transfer of data between server and client, this feature also enables almost instantaneous synchronisation of data.
  • Streams data: Using Node.js for development significantly accelerates the transfer of media such as music and videos. Rather than storing the data in a buffer, Node.js streams it in smaller pieces to the receiver. These streams enable real-time encoding of video or music, and only require the memory use of a single chunk of data rather than the entire file.
  • Costs of development are reduced because: The introduction of serverless architecture has revolutionised the way we manage programme performance. By automatically scaling resources to meet demand, this type of architecture results in a significantly lower cost structure when compared to conventional server architecture, as you are only charged for services when they are required.

Node.js development also allows you to combine the frontend and backend teams into a single, more manageable group.

The cost-effectiveness of Node.js cannot be overstated, as it is free and open source. Furthermore, the platform’s large user base provides access to a multitude of free, versatile customisation options, in addition to security best practices and advice from experienced developers.

Shortcomings of Node.js

It is essential to bear in mind that Node.js development does have a few drawbacks, such as the fact that it is limited to a single-threaded environment and the sheer volume of packages available on the Node Package Manager (NPM).

The use of a single main thread can be highly inefficient when dealing with intensive calculations, as the performance of the thread decreases with an increase in the CPU’s usage. Furthermore, in an event loop, a request that requires a large amount of resources can lead to a delay in the processing of subsequent requests, until the request is completed. Thus, there may be a requirement for specialised hardware and software to be implemented in order to handle a large amount of data on the server side.

Using third party Node Package Modules (NPM) can come with some drawbacks. Although having a range of options available can be beneficial, it can be difficult to decide which one is the most suitable for your purpose. Furthermore, as anyone can post content, the quality and reliability of free libraries and features can vary greatly. To ensure that you are able to use accurate and correct information, it is advisable to only use reputable sources.

Best Uses of Node.js in Industry and Business

Due to its microservices architecture, Node.js development can provide solutions for organisations of all sizes; from the most ambitious large-scale projects to the scaled-down requirements of smaller companies. Node.js is a versatile technology and is widely used in a variety of domains, including online entertainment, e-commerce, real estate, payment services, and online publishing. It offers an affordable and scalable solution for any business.

Because of its many advantages for development projects, Node.js has been adopted by some of the world’s most recognisable brands.

Selecting the Finest Node.js Tasks

Node.js is proving to be an invaluable tool for a wide range of projects, but it is particularly suited to applications which require intensive real-time data processing, Internet of Things (IoT) systems, and high-traffic websites.

Due to its compact size and rapid performance, Node.js is the perfect choice for real-time applications that need a permanent connection to the server, in order to update any changes made by the user in real time.

Moreover, Node.js can be utilised to construct microservices for monitoring and other features of the geo-distributed systems that make up the Internet of Things (IoT). It is extensively used in IoT applications and devices due to its real-time functions and data-focused orientation.

Node.js is an ideal choice for projects which are likely to encounter a considerable amount of traffic and must be able to manage multiple requests from users simultaneously. Node.js is capable of responding rapidly to each individual request, thus allowing it to handle high volumes of requests efficiently.

Inappropriate Times to Use Node.js

Despite its advantages, Node.js is not always an appropriate solution and there are certain scenarios in which it is simply not viable. It is a JavaScript runtime, but browsers already provide this capability. Consequently, it is not recommended for use in graphic design, multimedia production, or audio/video editing applications.

Despite the fact that Node.js has frameworks and tools for incorporating AI-based features into projects, it is not the optimal solution when it comes to AI and machine learning. Furthermore, Node.js makes it difficult to create even relatively straightforward programmes which only rely on server-side data transfer.

Full-Stack JavaScript Development Is Now Possible With Node.js

Node.js is a powerful tool that is now readily available to JavaScript aficionados, enabling them to take advantage of the benefits of full-stack programming. Node.js may prove to be invaluable in terms of speed, efficiency and cost savings, when it comes to the development of a wide range of applications, from real-time applications to Internet of Things devices and high traffic websites.
