Note: Due to the use of nodejs instead of node name in some distros, yarn might complain about node not being installed. A workaround for this is to add an alias in your.bashrc file, like so: alias node=nodejs.This will point yarn to whatever version of node you decide to use. If Yarn is not found in your PATH, follow these steps to add it and allow it to be run from anywhere.
What’s Node.js® and NPM?
Node.js® is a JavaScript-based environment which you can use to create web-servers and networked applications. You can also use it to perform helpful tasks on your computer such as concatenating and minifying JavaScript files and compiling Sass files into CSS.
NPM is a “package manager” that makes installing Node “packages” fast and easy. A package, also called a module, is just a code library that extends Node by adding useful features. For example, the “request” module simplifies the process of making HTTP requests so you can easily get web resources from other sites.
NPM is installed when you install Node.js®
Although there is a Mac installer program on the Node website, we recommend using Homebrew to install and update Node.
Prerequisites
Installation Overview
Installing Node.js® and NPM is pretty straightforward using Homebrew. Homebrew handles downloading, unpacking and installing Node and NPM on your system. The whole process (after you have Homebrew installed) should only take you a few minutes.
Installation Steps
Test it!
Make sure you have Node and NPM installed by running simple commands to see what version of each is installed:
How to Update Node and NPM
New versions of Node and NPM come out frequently. You can use Homebrew to update the software it installs.
How to Uninstall Node and NPMInstallation | Yarn

brew uninstall node
When you install a package using
npm install <packagename> , the latest available version of the package is downloaded and put in the node_modules folder, and a corresponding entry is added to the package.json and package-lock.json files that are present in your current folder.

npm calculates the dependencies and installs the latest available version of those as well.
Let’s say you install
cowsay , a cool command line tool that lets you make a cow say things.
When you
npm install cowsay , this entry is added to the package.json file:
and this is an extract of
package-lock.json , where I removed the nested dependencies for clarity:
Now those 2 files tell us that we installed version
1.3.1 of cowsay, and our rule for updates is ^1.3.1 , which for the npm versioning rules means that npm can update to patch and minor releases: 1.3.2 , 1.4.0 and so on.
But not for major version changes that break compatibility, which means, in this example,
2.0 and higher.
If there is a new minor or patch release and we type
npm update , the installed version is updated, and the package-lock.json file diligently filled with the new version.
package.json remains unchanged.
To discover new releases of the packages, you run
npm outdated .

Some of those updates are major releases. Running
npm update won’t update the version of those. Major releases are never updated in this way because they (by definition) introduce breaking changes, and npm want to save you trouble.
To update to a new major version all the packages, install the
npm-check-updates package globally:
then run it:
this will upgrade all the version hints in the
package.json file, to dependencies and devDependencies , so npm can install the new major version.
You are now ready to run the update:
