Generate QR code on your machine using Node.js

I spoke at an event last week, and on the very last slide, I had a QR code that was supposed to lead people to my contacts page. Well, it didn't. I used a service for "free" QR code generation, and the link expired. So, I learned my lesson and came up with a line that generates whatever code I need right into my terminal.
First you need to install the qrcode NPM module via:
npm install -g qrcode
and then run
> read -p "Enter the text for the QR code: " userInput && qrcode -o qr.png "$userInput" -w 1000 -q 1
This will generate an image qr.png. Enjoy free QR code generation.
