 One of the coolest things that you can do with NPM isn't an NPM command at all. It's NPX, which also comes standard with a recent version of Node. Just running NPX will give you all of the information that you need to know about NPX. Here's what it does. Surely you've heard of a project by the name of Create React App. Create React App does what it says on the tin and it creates ReactApps. It's very simple. Now, Create React App is designed to be used as a command line tool, the same way that Calsey is. Now, historically we could have installed this with that global flag and had it available to us, but it's being updated rapidly. So every time we use it, we would have to install it. NPX solves that problem for us by effectively downloading this package and running it, but just one time. It doesn't keep an artifact of it anywhere. So let's test this out with Create React App. We can actually just copy this command and run it. We'll just paste it here. It's a NPX Create React App and my app is fine. Actually, let's do more essential NPM. Without any installation, NPX just ran Create React App. Now I want to show you I do not have this installed in my system. I use NPM LS and the global flag to show that Create React App ain't here. Empty. Nothing. Nada. NPX used it directly from the registry. This is awesome. So let's make sure that everything worked. We'll CD into more essential NPM, run Yarn Start, and we're in business.
