Find out how to properly upgrade the Node.js version you have installed

Node.js can be installed in multiple ways on a system, and the upgrade instructions depend on how you first installed it.

If you installed Node using the official package

The easiest way to install Node is to download the official package from the Node.js website.

Node website

The official package contains an installer that will detect the existing version of Node.js and it will overwrite it with the new one.

If you installed Node using Homebres (on macOS)

Homebrew is a very popular way to install Node.js on a Mac.

If you did use Homebrew, upgrading Node is as simple as running

brew update #makes sure Homebrew is up to date
brew upgrade node

Homebrew might ask you to upgrade your xCode version to compile the package.

If you use nvm

nvm is a popular way to run Node. It allows you to easily switch the Node version, and install new versions to try and easily rollback if something breaks, for example.

It is also very useful to test your code with old Node versions.

When you use nvm, you can check the current version you are running by typing nvm current, which will give you the same result as node -v.

To list all the installed versions, run nvm ls.

You can install a new Node release (or any old Node release, too) using nvm install <VERSION>, for example:

nvm install 10.8.3

Once installed, you can set that Node.js version to be the one to use by typing

nvm use 10.8.3

This will set 10.8.3 to the default Node version, system-wide.

Are you intimidated by Git? Can’t figure out merge vs rebase? Are you afraid of screwing up something any time you have to do something in Git? Do you rely on ChatGPT or random people’s answer on StackOverflow to fix your problems? Your coworkers are tired of explaining Git to you all the time? Git is something we all need to use, but few of us really master it. I created this course to improve your Git (and GitHub) knowledge at a radical level. A course that helps you feel less frustrated with Git. Launching May 21, 2024. Join the waiting list!
