Recently when I started getting into React I saw a lot of people (including myself) getting confused when seeing npx instead of the very well known npm.

Some of us found it weird but didn’t give much thought, others thought it was a typo and even went into the trouble of “fixing” it by running npm instead of npx.

When I see something happening more than once, I consider it as being worth to be explained. That’s why this article, to all who had the same misunderstanding as me. what is the NPM? As we might already know, npm is a package manager for Node.js whose goal is automated dependency and package management.

It means that we can specify all our dependencies (packages) for a project in the package.json file and whenever someone has to install the dependencies for it, they should just run npm install and voila!

It also provides versioning i.e. it makes it possible to specify which versions of the dependencies our project depends upon, so we can, for the most part, prevent updates from breaking our project or use our preferred version. what is NPX? What npx does is the following: By default, it first checks if the package that is to be executed exists in the path (i.e. in our project); If it does, it executes it; Else, means that the package has not been installed, so npx installs its latest version and then executes it; This behavior, that is explained above, is the default one of npx, but it has flags that can be used to prevent it.

For example, if we run npx some-package --no-install means that we're telling npx that it should only try to execute the package named some-package, without installing it if it has not been installed before.

Example Let's say we have a package named some-package and we want to execute it. Well, without npx, to execute a package we would have to do it by running it from its local path, like this:

package.json file while become this shape. { "name": "something", "version": "1.0.0", "scripts": { "some-package": "./node_modules/bin/some-package" } }

to run it in npm npm run some-package. in npx .npx some-package
