## Getting started
This requires working GraphQL server to test with.
* Query:
- getAllBooks: [Book]
- getBookById: Book
* Type
- Book
- _id: String!
- title: String!
- author: String!
- price: Int!
then
```bash
> git clone https://src.cogto.com/sipp11/apollo-state-local-cache-example.git
> cd apollo-state-local-cache-example
> npm i
> npm start
