A Raspberry Pi based food ordering button

What is that ?

It works with a Raspberry Pi (B+ here, but any version should work) using Node.js and foodcommander, a food ordering CLI / library I created for that purpose.

At the time it only works at Domino's Pizza in France (but feel free to extend foodcommander to add your favorite franchise !).

Usage of the button is pretty simple:
