Node Js Brew

TABLE OF CONTENTS

Thanks for the great guide. Something I look up every time I have to set up a new laptop. One quick note/suggestion: I always seem to end up with issues down the road if I install yarn through homebrew, as it inevitably binds to a specific version of node, and when I switch between projects with different node versions I end up getting strange errors from yarn. Node.js is a javascript runtime environment. It encapsulates the google Chrome V8 engine and optimizes some special use cases and provides an alternative API that makes the V8 engine execute better in a none browser environment. It is a single thread, event-driven, and none block IO framework, all these characters make it runs very fast How To Install Node JS In Windows Read More ».

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

Node Js Brew

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.

Running 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:

  1. you don't need to install anything
  2. you can run different versions of the same command, using the syntax @version

A typical demonstration of using npx is through the cowsay command. 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 vue CLI tool to create new applications and run them: npx @vue/cli create my-vue-app
  • creating a new React app using create-react-app: 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

Use the @ 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.

Note: The packages on this page are maintained and supported by their respective packagers, not the Node.js core team. Please report any issues you encounter to the package maintainer. If it turns out your issue is a bug in Node.js itself, the maintainer will report the issue upstream.

Android

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 libicu package).

Arch Linux

Node.js and npm packages are available in the Community Repository.

CentOS, Fedora and Red Hat Enterprise Linux

Node.js is available as a module called nodejs in CentOS/RHEL 8 and Fedora.

For example, to install Node.js 12:

For CentOS/RHEL 7 Node.js is available via Software Collections.

Alternatives

These resources provide packages compatible with CentOS, Fedora, and RHEL.

  • Node.js snaps maintained and supported at https://github.com/nodejs/snap
  • Node.js binary distributions maintained and supported by NodeSource

Debian and Ubuntu based Linux distributions

Node.js binary distributions are available from NodeSource.

Alternatives

Packages compatible with Debian and Ubuntu based Linux distributions are available via Node.js snaps.

fnm

Fast and simple Node.js version manager built in Rust used to manage multiple released Node.js versions. It allows you to perform operations like install, uninstall, switch Node versions automatically based on the current directory, etc.To install fnm, use this install script.

fnm has cross-platform support (macOS, Windows, Linux) & all poplar shells (Bash, Zsh, Fish, PowerShell, Windows Command Line Prompt)it's built with speed in mind and compatibility support for .node-version and .nvmrc files.

FreeBSD

The most recent release of Node.js is available via the www/node port.

Install a binary package via pkg:

Or compile it on your own using ports:

Gentoo

Node.js is available in the portage tree.

IBM i

LTS versions of Node.js are available from IBM, and are available via the 'yum' package manager. The package name is nodejs followed by the major version number (for instance, nodejs12, nodejs14 etc)

To install Node.js 14.x from the command line, run the following as a user with *ALLOBJ special authority:

Node.js can also be installed with the IBM i Access Client Solutions product. See this support document for more details

macOS

Download the macOS Installer directly from the nodejs.org web site.

If you want to download the package with bash:

Alternatives

Using Homebrew:

Using pkgsrc:

Install the binary package:

Or build manually from pkgsrc:

n

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.

Node

If you already have npm then installing n and then the newest LTS node version is as simple as:

Nodenv

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.

nvm

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:
