Hello, I want to make an app that can display on any webpage, just like how Disqus or IntenseDebate render on articles & web pages.
It will display a mini-ecommerce store front.
I'm not sure how to get started. Is there any sample code, framework, or design pattern for these "widgets"?
For example, I'd like to display products. Should I first create a webservice or RSS that lists all of them? Or can one of these Ajax Scripts simply digest an XHTML webpage and display that?
thanks for any tips, I really appreciate it.
