BearBnB

BearBnB is an AirBnB clone for bears to demonstrate building a Dream/Psychic application complicated enough to leverage several of the powerful features of Dream and Psychic (including STI, polymorphism, has-many-through, serializers in addition to the default and summary serializers, soft-delete, and sortable).

A good way to follow along with building a Psychic app is:

  1. Have PostgreSQL and Redis running (e.g. by brew install postgres brew install redis & following post-install instructions for each)
  2. Create a new Psychic app with npx @rvoh/create-psychic bearbnb.
  3. Start with the third commit in the BearBnB commits (Generate User model).
  4. Then follow along with the changes, commit by commit, making the changes in your project. The commits are broken down into generated code and hand coded features, and the commit message includes generator commands that were run.
