In this tutorial, we use jq and curl to query a web service and retrieve JSON objects containing embedded arrays. We then invoke a command based on each element in the array rather than simply printing the values to the console. A special thanks to one of my readers, B. Anderson, who left a comment on my Consuming Web API JSON Data Using curl and jq post and provided this question for us to explore. Let’s get started!
Attention 📣 Node developers. We’re building highly functional applications, but it’s time to add some pizzazz and breathe new life into our software creations. In this article, we’ll learn how to sprinkle in some emoji to add sparkle✨ to our Node projects with the help of the node-emoji package. We’ll culminate our efforts with the creation of a command-line emoji picker that we can use in a variety of contexts.
Today, we will explore Winston, a versatile logging library for Node.js. Winston can be used in numerous contexts including in Node web frameworks such as Express, and Node CLI apps. We will also dive into features that make Winston a good fit for IoT applications such as logging timestamped entries to files. This article has been updated to reflect the latest generation of Winston at the time of this writing which is Winston 3.x.
It’s easy to install and upgrade Node.js on the Raspberry Pi as explained in my guides on installing Node.js and upgrading Node.js on a Raspberry Pi. In fact, it’s easy on any Linux-based system. For Windows systems, however, the default installation routine of downloading and running MSI files from the Node.js website is not so streamlined. I was not keeping Node.js on my Windows systems up to date due to the activation energy required to do the installations. Today, however, everything changes. In this article, we will learn how to install and upgrade Node.js on Windows from the command line—and make the ongoing upgrade process as easy as double clicking Read More
I’m now awake, everyone! I must have been asleep (and perhaps you were too) since the Debian apt ecosystem now includes an “apt” binary that vastly improves the way we interact with the Debian package management ecosystem. You can now use the single apt executable instead of apt-get, apt-cache, etc. for many common use cases. These are groundbreaking changes for the better! My hope is that this post will accelerate your productivity whether you are using Ubuntu, Raspbian, or one of the many other other Linux distros based on Debian. Scenario: You want to install the cowsay package because you know that a Linux system is not complete without it. 🙂 Given this context, let’s get started using Read More
Here’s a handy Windows shortcut I use quite frequently for launching a Windows command prompt in a specific folder using Windows Explorer. Thanks to fellow San Diegan Jon Galloway for teaching me this shortcut in one of his Microsoft Virtual Academy classes. Scenario: You are navigating through Windows Explorer to a folder of interest and realize that you need to drop down into a command prompt to run a specific command in that folder. For example, you want to launch Visual Studio Code from the command prompt using code . in that folder.
