A GraphQL query is for reading data. The schema defines the types of queries which are available to the clients connecting to your server.

## Material
|
|
|
|
|
|
|
|
|
|
* GraphQL query defines the shape of data that will be returned by a particular request
|
|
|
|
|
* This is what an author + books query looks like coming from the client
|
|
|
|
|
* make sure it has arguments

|
|
|
* This query is then checked again the server's schema
|

|
|
|
* looks like this:
|
|
|
|
|
* "root" level queries define the main entry points
|
|
|
|
|
* Each of those root queries returns a type
|
|
|

|
**Actually writing resolvers for your queries is found in server/queries**
