Making Interactive Node.js Console Apps That Listen for Keypress Events
In preparing for an upcoming Node.js IoT tutorial focused on creating notifications based on sensor values (for example, audible alerts), I wave of brilliance came over me. 🙂  Wouldn’t it be awesome if these notifications could be interactively acknowledged and silenced from the console? Lo and behold, I discovered that Node.js CLI (console) applications can indeed respond to keystrokes, ushering in a whole new realm of possibilities.  In today’s tutorial, I will teach you how to build interactive Node.js console applications that listen for keypress events. We’ll build a simple stock quote application to bring this interactivity to life.
