Node Fundamentals – Part 3

We start adding support for all the other commands inside of the notes application. We'll take a look at how we can create our read command. The read command will be responsible for fetching the body of an individual note. It will fetch all the notes and print them to the screen. Now, aside from all of that, we'll be looking at debugging broken apps, and we'll look at some new ES6 features. You'll learn how to use the built-in Node debugger.

Then, you will learn a little bit more about how we can configure yargs for the command-line interface applications. We'll learn how to set up the commands, their descriptions, and the arguments. We'll be able to set various properties on the arguments, for example, whether or not they're required, and others.
