The Fast-Growing IoT Industry

In 1999, IoT came into existence with Kevin Ashton’s idea of an RFID chip which he intended to use in supply chain management at Procter & Gamble. Years later, the same idea saw a reinvention as the internet became increasingly accessible across the world. According to IoT Analytics, the global market for the Internet of Things is expected to grow 37% from 2017 to $151B. Because of the growing pace of IoT, those calculations have been revised upwards, and it is currently expected that the total market will reach $1,567B by 2025.

The critical factors for IoT growth are the following:

  • Enhancing IT security standards for IoT devices.
  • The growth in scalable technologies.
  • Robust growth of cloud computing powers.
  • Pervasive APIs and comprehensive integration capacities.
  • Availability of IoT cloud software development.

Although there are numerous technologies involved in designing an intelligent connected system, The question is what could be the best possible platform which would ensure that the organizations are prepared and ready to use it?

Why is Node.js an ideal solution for the Internet of things?

In everyday life, we pass by a lot of people wearing smartwatches, now more than ever. Be it smartwatches, microwave ovens, washing machines, and even homes. All of them can harmoniously connect to your smartphone.  You just have to install an app that helps you manage tens of processes that your smart devices are engaged in.  This is where the charm of IoT begins, it lets you connect your mobile app with all the smart technology surrounding you in real-time.

We have all kinds of programming languages to create such solutions. Python, Java, C ++, Ruby, all of them can take care of building IoT platforms and do an excellent job. But, as far as programming languages that were made particularly for such kind of development, all of them hide in the shadow of JavaScript, which works the best for developing IoT applications. JavaScript itself is not perfect, but the inclusion of Node Js development makes it relatively better.

Node.js has a multimillion community of Node Js developers for web project ideas, a great number of libraries and the capability to work stably on heavily loaded projects, without taking much of a server’s resources. Node.js is an environment that executes on the server’s side.  It is extremely powerful, and at the same time, easy to learn the tool that developers use for creating big and multifunctional projects. Here are some major reasons to use Node.js development for IoT applications.

Speedy and real-time execution

The topmost advantages of using Node.js in IoT application development is that it is fast-paced and executes in a real-time environment. Node.js comes with NPM (Node Packaged Modules) that has more advanced repositories to meet the IoT needs. Packed with V8 engines powered by Google, Node.js compiles JavaScript into a native machine code that provides extremely fast execution. The NPM repository involves over 80 packages for the Arduino controller and multiple packages for the Fitbit and Pebble wearable devices. Additionally, it also contains several built-in architectures for Bluetooth devices and sensors.

Node.js also has fast data synchronization abilities, which decreases the time needed to send and receive data from the server. The transfer takes place almost in real-time, making IoT devices extremely efficient and responsive.

Easy Integration with IoT protocols

Integration is one of the factors that IoT relies heavily on. If you’re developing an application that readily integrates with the current data services, the possibilities of adoption rise significantly. The integration is executed at the backend level. Node.js supports the MQTT protocol, which is generally used by IoT applications to interact with each other. Using Node.js lays a solid foundation for your application to easily connect it to independent and 3rd party services and prepare it for integration across environments. It’s similar to the ability to connect to the Uber app, nest doorbell, and Smart TV seamlessly, creating market opportunities for your project.

Resource Efficiency

IoT devices are abundant in numbers. In 2020 alone, the calculated number of IoT devices reached 20 billion. Managing such a massive network of devices requires heavy computing powers that can become a roadblock for the project as the prices rise exponentially. Node.js has lower runtime, which means it uses fewer resources to run the same application built on other popular technologies such as Java or Ruby on Rails. For example, an 8 GB RAM device can handle 4000 concurrent connections at a time considering each thread takes up 2 MB of memory, using traditional web development techniques.  With Node.js, the same device can handle 1 million concurrent connections.

Scalable and Portable

Systems, tools, things, and sensors support for working Node on ARM platforms and processors. Unnecessary to believe that it works on all kinds of Edge Devices – Gateways, Concentrators, Routers and any platform that supports Linux is expected to support Node. What this shows is that developing a distributed software system across your workflow, especially in IoT, Node and Javascript help you to build a comprehensive end to end application. The capacity to develop a distributed software system also supports working “cloud” apps on the edge without the need for Internet connectivity. This is extremely useful in use-cases such as Healthcare (conducting surgeries or medical checkups) and testing a system that can work without connecting to the Internet.

Mobile APIs

The most broadly accepted use of Node.js is APIs (Application Programming Interface). For instance, Linkedin was the first who built mobile API using Node Js development tools. Node.js is one of those platforms that comes integrated with many frameworks such as Hapi. Express and Restify are other Node.js web service frameworks optimized for building semantically correct web services and creating APIs. It becomes effortless for Node Js development company to build the API as they need to write only a few lines of code to get started with an API.

Manages requests efficiently

Node.js is the best technology that any IoT application development company can use for efficiently handling the large surges of requests generated within the devices such as sensors and wearables. Streaming of the data is smoother with Node.js as it does not require caching. Stream instances are the Unix pipes that are readable and writable as well and the Node.js developers can effortlessly work with them for running stream applications. With the help of Stream, a user can directly stream data to its destination.

Managing and Securing Data

For IoT devices security lies in three main components:

  •   Accurate and thorough code architecture
  •    Access rights for different types of functional
  •    Verification of devices and users authenticity

IoT is all about collecting data, communicating, interpreting, and developing. Node.js is known for its acceleration, scalability, and performance delivering it the key player for data-driven real-time application. This makes Node.js perfect for IoT applications that rely on data-intensive real-time traffic. NodeJs for IoT application development is a perfect partner for all the IoT features.


The IoT market is bringing innovation as we slowly move into an interconnected world. Smart cities, smart devices, smart mobility, and personalized healthcare, everything is predicted to ride the IoT train in less than 5 years from now. Node.js application development helps you stay ahead of the curve and beat the competition with its tailor-made services for IoT projects. Also, laying your web foundation by using Node Js for web development will be among the most beneficial decisions you will take while starting your IoT journey.  Make sure to hire dedicated Node.js developers for IoT development and define your requirements to them to experience a seamless application development procedure.
