NPM is short for Node package manager and is known to be the largest software registry in the world. It is the default Node.js package manager. It is actually written in JavaScript and was originally released on 12th January 2010, by Isaac Z. Schlueter. For node.js, npm manages all packages and modules and comprises the npm command-line client.

Also with the installation of node.js, it gets installed into the system. In the Node project, the packages and modules needed are installed using npm.
A package includes all the files required for a module, and JavaScript libraries are modules that would be included in the Node project as required by it.

You need to install Node.js to have npm installed on your system. A CLI that could be used to download and install packages is included with npm.

npx vs npm - THE npx ADVANTAGE
We first need to build package.json to begin to work with npm (this file contains much project-relevant metadata. The file is used to send npm data that enables the project to be defined and the dependencies of the project to be handled) by executing the following command:

npm init -y
This command generates the package.json file with the default configuration in the current directory since we made use of the -y flag. We may run the following command to add packages from the npm registry:

npm i eslint
Features of NPM
npm compristes of 3 major aspects:

the website
the Command Line Interface (CLI)
the registry
What is NPM used for?
Adjust code packages for your programs, or integrate packages as they are.
Install independent software that you can instantly use.
Operate packages using npx without downloading.
Share the code with any user of npm, anytime.
Restrict individual developers to code.
Build organizations to coordinate managing, coding, and creators of packages.
By using organizations, shape virtual teams.
Several code versions and code dependencies are handled.
Easily upgrade software by upgrading the underlying code.
Discover different ways of solving the same puzzle.
Find other developers who are working on issues and projects that are similar.
What do we understand by NPX?
Npx is basically short for Node Package Execute and comes with npm, which automatically installs npx when you have installed npm above 5.2.0. It’s an npm package runner that can run any package from the npm registry that you like without even downloading that package. It’s an npm package runner that can run any package from the npm registry that you like without even installing that package. The npx is beneficial for a single package of time consumption.

NPX is also a CLI application intended to enhance the experience of using the npm registry packages (npm version 5.2.0 NPXis pre-bundled with npm – tnx StefanT123 ). It is simple to run any kind of Node.JS-based executable with NPX. Let’s look at some examples:

We have two options for implementing Eslint:

./node_module/.bin/eslint --init
Since all the executable nodes in the .bin directory running the above command are not so user-friendly, we can make use of npx: instead which can work in a better way for us.

npx eslint --init
When you do not wish to use NPX for any reason, you can install eslint globally:

npm install -g eslint
The package will now be installed in node modules in the user directory of your computer, which ensures that you can execute eslint globally in any directory.

Features of NPX
Simple and quick to run local commands.
Allows running commands without first installing them.
Runs some code using a different Node version.
Runs arbitrary code snippets directly from a URL.
You can execute npx commands with \$npm_ Environment Variables.
You can also execute Code from a Remote GitHub Branch with npx.
NPX is also used to execute code from a GitHub gist.

NPX vs NPM: The Difference
The following difference between NPX & NPM will make things even more clear to you. The difference will point out how each one of them is different from the other. Let us go ahead and see how both of them are different from each other:


What is the Advantage of NPX?
You can save yourself storage space and actually run them with npx when you really need it instead of downloading node executable packages worldwide that you are likely to use less frequently. This means that any node executable package on the npm registry can be used with the installation necessary.

You don’t need to install create-react-app globally on your computer and may not have to worry regarding updates since npx will still try looking up the npm registry and run the create-react-app with its latest version whenever you run npx create-react-app.

Installing npm packages globally a lot of times needs sudo. With npx, you can easily execute a node executable anywhere without sudo.

When you just want to give it a whirl, you don’t have to install a CLI tool from the npm registry.

npx
You may also use npx to run your scripts without adding $PATH variables.

npx ./my-script.js
Intriguingly, you may mix npx powers with an executable node package in the npm registry that installs a binary node into your project (so that you can provide a local version of a node that is different from that of your device and handle the node as a standard dependency) much like nvm. You can run commands that have various versions of Node.js with this mixture.

Key Takeaways
Till now all of us might have gotten an idea that npm is a Node.js package manager whose purpose is to handle automated dependencies and packages. This implies that we may specify all our dependencies (packages) for a project in the package.JSON file and when anyone has to install the dependencies, they can simply run npm install and they will get what they are exactly looking for. It also offers versioning, i.e. it allows us to define which versions of the dependencies the project relies on so that we can avoid changes from destroying our project or using our preferred version for the most portion.

Whereas, npx is a Node package execution tool and comes bundled with npm beginning with npm5.2 version onward.

Summing up what NPX really does:

By definition, it first tests if the executable package is present in the path (that is, in our project).
It executes it if it does.
Otherwise, it implies that the package was not installed, so npx downloads the new version of the package and then runs it.
This behavior is the default one for npx but it has certain flags that can be made to use to prevent it. For instance, if we run some-package npx —no-install indicates we’re telling npx that we must only try to run a package called some-package, without having to install it if it was never made to install before.
