npx is a very powerful command that's been available in npm starting version 5.2, released in July 2017.
If you don't want to install npm, you can install npx as a standalone package
npx lets you run code built with Node.js and published through the npm registry.
Easily run local commands
Node.js developers used to publish most of the executable commands as global packages, in order for them to be in the path and executable immediately.
This was a pain because you could not really install different versions of the same command.
npx commandname automatically finds the correct reference of the command inside the
node_modules folder of a project, without needing to know the exact path, and without requiring the package to be installed globally and in the user's path.
Installation-less command execution
There is another great feature of
npx, which is allowing to run commands without first installing them.
This is pretty useful, mostly because:
- you don't need to install anything
- you can run different versions of the same command, using the syntax @version
A typical demonstration of using
npx is through the
cowsay will print a cow saying what you wrote in the command. For example:
cowsay 'Hello' will print
This only works if you have the
cowsay command globally installed from npm previously. Otherwise you'll get an error when you try to run the command.
npx allows you to run that npm command without having it installed locally:
will do the job.
Now, this is a funny useless command.Other scenarios include:
- running the
vueCLI tool to create new applications and run them:
npx @vue/cli create my-vue-app
- creating a new React app using
npx create-react-app my-react-app
and many more.
Once executed, the downloaded code will be wiped.
Run some code using a different Node.js version
@ to specify the version, and combine that with the
node npm package:
This helps to avoid tools like
nvm or the other Node.js version management tools.
Run arbitrary code snippets directly from a URL
npx does not limit you to the packages published on the npm registry.
You can run code that sits in a GitHub gist, for example:
Of course, you need to be careful when running code that you do not control, as with great power comes great responsibility.

Android support is still experimental in Node.js, so precompiled binaries are not yet provided by Node.js developers.
However, there are some third-party solutions. For example, Termux community provides terminal emulator and Linux environment for Android, as well as own package manager and extensive collection of many precompiled applications. This command in Termux app will install the last available Node.js version:
Currently, Termux Node.js binaries are linked against
system-icu (depending on

n is a simple to use Node.js version manager for Mac and Linux. Specify the target version to install using a rich syntax,or select from a menu of previously downloaded versions. The versions are installed system-wide or user-wide, and for moretargeted use you can run a version directly from the cached downloads.
See the homepage for install methods (boostrap, npm, Homebrew, third-party), and all the usage details.
If you already have

nodenv is a lightweight node version manager, similar to
nvm. It's simple and predictable. A rich plugin ecosystem lets you tailor it to suit your needs. Use
nodenv to pick a Node version for your application and guarantee that your development environment matches production.
Nodenv installation instructions are maintained on its Github page. Please visit that page to ensure you're following the latest version of the installation steps.
Node Version Manager is a bash script used to manage multiple released Node.js versions. It allowsyou to perform operations like install, uninstall, switch version, etc.To install nvm, use this install script.
On Unix / OS X systems Node.js built from source can be installed usingnvm by installing into the location that nvm expects:
After this you can use
nvm to switch between released versions and versionsbuilt from source.For example, if the version of Node.js is v8.0.0-pre:
