Install nodejs

We need to install Node.js (we'll use v15.x) and the npm package manager. You can download directly from Node.js or in your terminal:

curl -sL https://deb.nodesource.com/setup_15.x | sudo -E bash -

sudo apt install -y nodejs
# You can use homebrew (https://docs.brew.sh/Installation)
brew install node

# Or you can use nvm (https://github.com/nvm-sh/nvm)
nvm install node

We can verify that everything is installed correctly by querying the version for each package:

node -v
npm -v
