Choosing appropriate tools, platforms, and the right programming languages is an important aspect of the functioning of future apps. This is concurrently from the development, performance, and efficiency of the systems of servers. Generally, developing a web application needs you to evaluate the merits and demerits of building your stack using JavaScript with tools using it.

Therefore, if you think of a basic backend development platform, Node.js automatically comes to mind. Node.js comes in handy with many benefits even though it is not suitable for every project, and outsourcing Node.js development services from notable software developers is a crucial task.

What is Node.js?

Node.js is an open-ended server environment that runs effectively on numerous platforms using JavaScript. The server is not a framework but rather a working environment that allows JavaScript code execution on the server-side. Since the inception of Node.js in 2009, it has gained much popularity. The following are the core elements of Node.js.

The engine

The development of Node.js is majorly based on JavaScript’s Google Chrome V8 engine. This makes it work very fast and lightweight enough for code execution.

Node package monitor (NPM)

Node.js is controlled and supported by a document-based database model, unlike SQL. The NPM has a large resource-based library where you can easily and swiftly import any functionality for your application. Access to NPM can help you reuse codes and build apps quickly.

The event-driven architecture

Node.js runs on one single thread while initiating multiple and simultaneous requests. When no data is returned to server calls, the user-friendly Application Programming Interface (API) moves swiftly to the next API. The working module helps the server get an immediate response from the prior API.

What is the use of Node.js?

Node.js is used practically to provide web development solutions to achieve better and more effective application performance. The practical aspects of the use of node.js can be looked at below.

1. The Internet of Things (IoT) applications

The integration of Node.js IoT is important in implementing IoT development tasks. Firstly, the fast and powerful nature of node.js can help handle immense data flows. Secondly, you can integrate Node.js with the Internet of Things Protocols. Also, the Node Package Manager has many important IoT modules that help implement desired IoT projects.

2. Real-time applications

The great speed and high performance of Node.js can enable real-time chatting and messaging. The well-coordinated environment can support huge traffic of countless short messages or chartrooms with a clear display of too many users in real or at the same time.

3. Data streaming applications

The inbuilt modules support data streaming by allowing the creation of writable and readable data streams. This is important for audio and video applications for streaming. Large amounts of data are sent instantly in smaller packages but not in single batches.

4. Collaborative tools

Since Node.js is effective in processing real-time data flows, it is important for applications that require immediate updates like online documentation suites.

Why should you use node.js development?

Node.js development is developed to ensure scalable web applications designed for high traffic need solutions. It is much beneficial because it offers a wide range of merits.

  • Scalable and efficient. The Microservice feature of Node.js splits diverse aspects of the app into different services to handle multiple tasks. This eases the scaling of apps and implements extra functions needed.
  • Easy to learn. Most developers know how to use JavaScript; starting to use Node.js cannot strain you much to learn. Provided you know JavaScript, writing node.js is a no-brainer task.
  • Lower development costs. The serverless features enable apps to adapt and scale up automatically as they respond to heavy traffic. Also, you pay only for services if the functions are used. This lowers the standard cost of server architecture.
  • It supports data streaming. Node.js is a powerful and fast tool that reduces the processing time of uploading video and audio files. It transmits data in streams, thereby buffering data from huge chucks that take up much space.

Companies and industries using Node.js development

Node.js development is agile and flexible in helping grown and developed companies with their large-scale projects. Also, it works well with startups, given their low development costs and scalability.

Many successful industries like real estate, eCommerce, publishing, and online entertainment use Node.js. Here are some companies that use Node.js concerning the benefit solution they provide.


PayPal is an international financial system for sending and receiving money. Node.js is significant in Paypal since it ensures fast built times and the essence of handling large amounts of data.

Node.js has been a good transformer in advancing features offered to the client-side. It has also improved the process of handling concurrent requests.


The uber sector has seen unmatchable benefits like active open source communities. Node.js has improved the facilitation of complex matching systems to fit the transport sector.


Since Netflix handles a lot of movies, series, and documentaries, there is a need for easy transformation of concurrent events to respond to traffic spikes. Node.js helps in improving the scalability and handling of intensive apps with data.

When not to use Node.js development

Node.js is not used in every situation. First, you can’t use it in the browser since it is a JavaScript runtime that exists in the browser. Secondly, you should not use to process graphics and images or audio and video editing.

In addition, it is not a great choice for Machine Learning (ML) and Artificial Intelligence (AI), even though it has tools and libraries for integrating AI-based elements into apps if needed. Moreover, nodes.js complicates the development of simple apps that directly transmit data from the server.


Node.js is a powerful tool that provides exceptional performance in various applications. It has improved many aspects in various industries to attain much reputable success. With constant and progressive developments, Node.js is on the verge of becoming a better choice in different sectors.
