How to install Node.js

So many tutorials start with npm install, but how do you go about actually installing this npm? I have to look it up fairly regularly, so here are my notes.

Node and Homebrew are apps

Homebrew and Node are both installed globally for your user on your computer. Consider them software on your computer in a similar way to Word or Photoshop, tools to create things.

Homebrew

Annoyingly, I'll start with installing something else before installing Node. Welcome to the world of package managers. There's always another thing to install before the thing you came to install :/

And this time that other thing is "Homebrew". Shortly explained, it helps us installing other things in the Terminal. To install we need this snippet from it's website:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

It asks for your password to be allowed to create a bunch of new files and folders on your computer.

Check if Homebrew is installed

brew --version

If Homebrew is installed, it should return Homebrew 2.2.4. (That's the current version number, it will most likely have changed when you read this)

Install Node and NPM

We can now use the new brew command to install node:

brew install node

It takes a while to download and install.

Check if Node is installed

We can check if Node is installed the same way we checked if Homebrew was installed. By adding the --version attribute to the end of the command.

node --version

node -v // This returns the same result

Today, that command returns v10.13.0

Check if NPM is installed

npm -v

And today, this returns 6.13.6.

Node vs NPM?!
