Before answering, we'll briefly examine how IoT frameworks should work. The IoT framework should handle streams of data in real time while maintaining pace. Also, they deal with data visualization processing and constant management tasks to allow users to automate their environment. Today, there are a vast number of technologies, and Node.js is one of those that is considered advantageous for IoT development. Let's see why.
The prime benefit of Node.js is that it works stably on heavily loaded projects without using much of a server's resources. It's a good fit for big and multifunctional projects. Most IoT projects use the MQTT protocol and standard Web Socket, which support Node js. Node.js is the framework that is used with real-time apps and provides high efficiency through processing constantly changing data. Node js also streamlines IoT development thanks to modules for various sensors, beacons, and other IoT tools provided by Node Package Manager. Finally, since the framework doesn't require many resources, the CPU and RAM aren't overloaded.
