How and Why You Should Build Internet of Things Devices with Node js

In the case of quality assurance uses, developers can debug and get greater visibility into processes during product bake-in, a huge value add and tremendous resource saver. For example, LinkedIn developers were the first to develop a mobile API by Node.js development tools. The platform integrates Node.js frameworks for building web services and APIs.

  • However, the hardware should store this token or login/password data in firmware.
  • Anytime a user has endpoints running Node.js in the field — whether it be in chipset or a kiosk/device — they need to ensure their apps are running, and doing so effectively.
  • Also, it is capable to sync the data with speed, which saves time in sending and receiving data from the server, making the IoT-connected devices responsive and powerful.
  • With Node.js, this same device can hold one million simultaneous connections.
  • The light-weight runtime is built on Node.js, taking full advantage of its event-driven, non-blocking model.

It also effectively handles the large number of requests that are generated within the IoT integrated devices such as sensors and wearables. Also, it has 30 packages that are useful for various sensors, beacons, and other IoT development tools, catering to the development of IoT apps simpler and faster with Node.js IoT modules. Although JavaScript is the primary language supporting NodeJS, other compile-to-JavaScript languages like TypeScript, CoffeeScript, Dart, and ClojureScript can also use NodeJS. With NodeJS, an event-driven programming paradigm is brought to the web servers leading to faster development of web servers. For many IoT companies and situations, Node.js is tremendously popular – it’s easy to use and rarely breaks. But when a problem does arise, understanding what went wrong, where, and how to fix it is very hard to do; whenever possible, eliminating these bugs before devices are mass produced is critical.

Why Choose NodeJS For IoT Applications?

Accurate code architecture, Access rights for different functions, and User authentication and verification. Client libraries targeting some end-of-life versions of Node.js are available, and can be installed through npm dist-tags.

We all must have come across smartwatches and smart devices that are accessible via a mobile phone and this is where IoT plays its role. It lets you connect the smart devices around your surroundings with your smartphones in real-time.

Node.js is easy to integrate with IoT protocols

All this helps to boost the company’s performance and productivity. The client-side of an IoT device is represented by the hardware itself. It is programmed with C, C++, or Lua – low-level and difficult programming languages.

  • NodeJs is event-driven and asynchronous in nature which makes it scalable and reliable and is used for both frontend and backend development.
  • These devices are connected via sensors and other communication networks and are also known as ‘Smart Devices’.
  • A Node.js company can quickly create an API since it only takes a few lines of code to write.
  • Collaborate with us as partners to relish stupendous customer support.
  • It also contains more than 30 packages for a variety of Bluetooth devices and sensors.

The technology also came in handy for finding areas affected by the earthquake in Nepal. Despite the pandemic, the IoT market keeps growing, so does the spending on IoT.


Smart cities and devices, intelligent transport and logistics, personalized healthcare are already a reality that needs software support. But as regards languages designed especially for this kind of development, none of them compare to JavaScript. Despite some shortcomings, it’s more than excellent for developing IoT applications. In this step, you will create a new identity pool, which will help you to connect your client application to the IoT Core service. Sensors, motors, transmitters, etc. generate large volumes of data and a large number of requests, Node.js is apt for handling these.

How difficult is IoT?

Not so much. IoT is off to a slow start and there's a reason — it's hard . So hard, Gartner predicts through 2018 that 75% of IoT projects will take up to twice as long as planned.

Node-RED is built on Node.js, taking full advantage of its event-driven, non-blocking model. Node-RED is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways. Global organizations partner with us to leverage our engineering excellence and product thinking to build Cloud Native & Data-Driven applications. A large number of IoT applications use MQTT protocol and the standard Sockets which have a great support in Node.js. Additionally, as per the insights from Statista, the global IoT market was worth near $389 billion in 2020 and is forecasted to reach more than $1 trillion in 2030. This means that there are positive signs for businesses and companies who are thinking of introducing this technology to their business.

Social Development

Now that you know the few reasons that we think are important to know before choosing NodeJS as the core framework for developing IoT apps, you can go ahead with this framework for your project. These are just a few of the reasons to choose NodeJS for the development of IoT apps and there are many more reasons that you will explore with thorough research before starting the development process. Furthermore, security is an important factor when it comes to the development of IoT-integrated applications and its security lies in three main elements i.e.

  • Adding more to it, it also serves with built-in architecture for Bluetooth devices and sensors that are integrated into the IoT apps.
  • A large number of IoT applications use MQTT protocol and the standard Sockets which have a great support in Node.js.
  • These greatly help to speed up and simplify the application development process.
  • Hardware is not a browser and you should implement HTTPS manually on it.
  • Despite the pandemic, the IoT market keeps growing, so does the spending on IoT.

There are about 80 packages for Intel IoT Edison, Arduino, or Raspberry Pi. Also, it features over 30 packages for different sensors, beacons, and other tools.

It’s architecture allows ephemeral artifacts to be moved to a stable, user determined location. Even if the the process goes down, the artifacts remain long after a crash or device termination.

We should note that a reasonably extensive selection of programming languages is available to developers to create such solutions. Java, Python, C ++, Ruby are widely used for IoT software development and do an excellent job with this task. The light-weight runtime is built on Node.js, taking full advantage of its event-driven, non-blocking model. This makes it ideal to run at the edge of the network on low-cost hardware such as the Raspberry Pi as well as in the cloud. In this application, you will create an AWS IoT Core client using Node.js and will then send data to the AWS IoT server using the MQTT protocol. You can connect anything to the Internet, but the problem is connecting all this using a standardized protocol. Also, the house of IoT is built on a foundation of low power and battery efficiency.
