Node.js IoT – Create Local Module for CPU Sensor

[Dave Johnson]

In this article, I explore the process of refactoring a CPU sensor in Node.js by creating a local module for better organization and adherence to the Node.js philosophy of building small, single-purpose modules. The tutorial guides readers through breaking out the CPU load functionality into a separate module, updating the main program to utilize this new module, and simulating an npm module using the npm link command. This approach not only simplifies the main program but also prepares the groundwork for future enhancements, such as real-time data visualization of CPU metrics.
