I've left a trail of commit messages that is hopefully easy to follow. I might try to make a video soon.

• Create a new Phoenix app.
• Install Absinthe and configure it to work with Phoenix.
• Create a database schema with some basic relations; Hook it up to GraphQL schema. At this point we have a naive GraphQL schema. The resolvers cause some horrible database queries to happen.
• Set up Dataloader with Absinthe to improve performance of database queries.
• Update schema and resolvers to handle arguments for filtering.

1. Install dependencies mix deps.get
2. Create database mix ecto.setup
3. Create database schema and populate with data mix ecto.drop; mix ecto.create; mix ecto.migrate; mix run priv/repo/seeds.exs
4. Start the Phoenix server mix phx.server
5. Run GraphQL queries (and browse schema documentation) from your web browser at http://localhost:4000/api/graphiql
