ProductReview Example
Introduction
This page contains a description of an example project that can be used to study different implementation techniques using VDF as a backend.
In this example the overall goal is to be able to see what users think about a particular item . As an added benefit - users can also share information about where to buy the particular items.
To accomplish this, then users should be able to:
- login
- choose an item from a list
- enter information about a known item
- supply information about the place where an item was bought.
- supply a review of an item
- Overview supplied reviews from other users
The workspace is available here https://github.com/jacobandresen/ProductReview
