Building my own `like` system

I am thinking to build my own like system, as a way of learning

various technologies including Javascript; and to gain a better

understanding of authentication and XSS. Most importantly though, this

will provide a fun project with which to learn Ruby on Rails.


  1. Unique ID generated atop a little bit of Javascript code, for

embedding in any website

  1. When unique user presses this like button, a +1 is triggered to

the ‘score’ of that UID

  1. On unique user’s profile, display what they like’d

I’m unsure as where to start… how would I go about building this

system? — i.e. Should I be looking at Inoshi?

Thanks for all suggestions,


I recommend the book: “Service Oriented Design with Ruby and Rails” by Paul Dix

There you will find something similar.
