Node.js IoT – Create Local Module for CPU Sensor

We’re back and ready to do some refactoring of our CPU sensor so we can learn about Node.js modules and how to create them. Building small, focused modules is one of the key tenets of the Node.js philosophy as summarized in The Node Way: Building small, single-purpose modules is at the heart of the Node.js philosophy. Borrowing from Unix, Node.js encourages composing the complex and powerful out of smaller, simpler pieces. This idea trickles down from entire applications (using the best tool for the job vs. a full suite) to how the tools themselves are built.

Node.js IoT – Build a Cross Platform CPU Sensor

I took a little hiatus in our series to take my family on a trip to Japan with layovers on each end of the trip in China which included a ride on the Shanghai Maglev Train, the fastest train in the world. We had a fantastic time, and it was a great educational experience for the kids. It is also good to be back home! We are back again with our Node.js IoT tutorial series and ready to continue developing our “CPU sensor” as CPU loading/utilization is a “sensor” we can measure, record, and ultimately stream to other locations. Today, we will expand our CPU sensor and make it cross platform—and learn more about Node.js in Read More

Node.js Learning through Making – Build a CPU Sensor

We are back with our LTM (Learning through Making) tutorials and ready to hit the ground running and write some real Node.js code! In this series, we will learn about Node.js in the context of creating IoT (Internet of Things) projects. We will build a “CPU Sensor” in this first project since CPU loading/utilization is a “sensor” we can measure, record, and ultimately stream to other locations. In future tutorials, we will harness the power of Node.js to interact with physical sensors that live outside of our computing environment.

Using Visual Studio Code with a Raspberry Pi (Raspbian)

We’re back with our LTM (Learning through Making) series of Node.js tutorials and we’re gearing up and getting ready to write some code! We’ve learned how to build a Raspberry Pi from the ground up including Node.js, we’ve created a web server in Node without code, and we’ve even managed to get this web server on the Internet as a cool trick. So how are we going to write Node.js code? There’s nothing that would stop us from simply jumping onto our RasPi and using the Leafpad text editor or even the nano console-based editor to write our code. I propose that we use some more robust tools in the form of an IDE (Integrated Development Read More

Visual Studio Code Jumpstart for Node.js Developers

Visual Studio Code is an amazing, lightweight code editor and works great for Node.js development. I like it so much that I am recommending it for those doing the free Learning through Making (LTM) tutorial series I am creating. My Using Visual Studio Code with a Raspberry Pi (Raspbian) article is closely coupled to this article; however, this article is intended to help you develop with VS Code whether you are using a RasPi or not. Now, let’s get started with first things first. This article is geared toward awesome, cutting edge people who want to develop with Node.js and leverage the latest ES6 (ES2015) features rather than being content living in yesteryear. 🙂 Am Read More

Create a Web Server in Node without any Code

Welcome back! In a previous tutorial (Beginners Guide to Installing Node.js on a Raspberry Pi), we installed Node.js on a Raspberry Pi. We are now ready to continue our LTM (Learning through Making) tutorial series and build a simple web server without any code. While this tutorial is geared toward the RasPi, the instructions can be easily mapped over to other platforms such as Windows, Linux, and OS X. Let’s get started!
