Phoenix GraphQL Tutorial with Absinthe

Would you mind explaining how could we query to this application like you do in your tutorial?

I thought the only difference would be author/user and that Ryan uses a database instead of hard-coded data, however the query:

export default graphql(gql`
  query posts {
    id
    title
    user {
      id
      name
    }
  }
`)(PostList);

This query doesn’t work either:

export default graphql(gql`
  query allPosts {
    posts {
      id
      title
      user {
        id
        name
      }
    }
  }
`)(PostList);

Both return the error “posts is undefined”.

Edit: the old trick of posting it to figure it out one minute later, Ryan uses “/api” to forward requests, you use “/graphql”, is it possible to change it?
