How to set default values in Graphql Schemas
I think setting default GQL values is best illustrated through two annotated examples:
1) Setting a default for a non-nested type:
In the below example the CoffeeOrder type has a field of size which sets a default value for the CupSize type of SMALL.
type CoffeeOrder {
name: String!
size: CupSize = SMALL
}
Annotated spec:
field: FieldType = defaultValue
2) Setting a default for a nested type:
The below example is a different implementation of the CoffeeOrder type. This time there is a field cup that contains a field size, which has a default value of SMALL:
type CoffeeOrder {
name: String!
cup(size: CupSize = SMALL): Cup
}
Annotated spec:
field(subfield: SubFieldType = defaultValue: FieldType
