 A React application using Apollo Client with [apollo-cache-redux](https://github.com/rportugal/apollo-cache-redux) for state management. Rather than having Apollo Client (apollo-cache-inmemory) and Redux side by side, this library attempts to **combine both worlds (Apollo, Redux) to manage local and remote state**.
