NPM and NPX are two Node tools used to manage packages from the NPM registry. The significant difference between both tools is that NPM is used to install (or download) packages, while NPX is used to execute packages.

Let's take the create-react-app package as an example to understand these Node tools.

create-react-app is a Node package used to bootstrap a React application upon which you can then add your packages and build your components.

To use this package with NPM, you have to install the package globally and then execute it like this:

npm install create-react-app -g

After installing the package, then you can execute it by running:

create-react-app my-app

It works differently with NPX. NPX skips the download process and executes it directly. With NPX, you will run the package like this:

npx create-react-app my-app

This command will execute the package directly from the NPM registry.

Should you use NPM or NPX?

So which one should you use? My recommendation:

If you’re using a global package often, it would be helpful to install it with NPM so that executions can be faster (since it’s already downloaded).

But if you only want to use a global package one time (or rarely), and you don’t want it downloaded to your device (and also occupy storage), you can use NPX to execute it directly.
