/**
|
|
* Object Type Definition
|
|
*
|
|
* Almost all of the GraphQL types you define will be object types. Object types
|

* have a name, but most importantly describe their fields.
|
|
*
|
|
* Example:
|
|
*
|
|
* const AddressType = new GraphQLObjectType({
|
|
* name: 'Address',
|
|
* fields: {
|
|
* street: { type: GraphQLString },

* formatted: {

* type: GraphQLString,

* resolve(obj) {

* return obj.number + ' ' + obj.street
|
|
* }
|
|
* }
|
|
* }
|
|
* });
|
|
*
|
|
* When two types need to refer to each other, or a type needs to refer to
|
|
* itself in a field, you can use a function expression (aka a closure or a
|
|
* thunk) to supply the fields lazily.
|
|
*
|
|
* Example:
|
|
*
|
|
* const PersonType = new GraphQLObjectType({
|
|
* name: 'Person',
|
|
* fields: () => ({

* name: { type: GraphQLString },
