Add custom GraphQL types
Usage
It must be an object with the following structure:
types: {
<GraphQLTypeName>: {
description: <description>,
interfaces: [
<InterfaceGraphQLType>,
// the rest of interface types...
],
fields: {
<fieldName>: {
type: <graphQLType>,
args: {
<argName>: <graphQLType>,
// the rest of argument definitions ...
}
},
...
},
},
...
}
For example:
types: {
CustomInterfaceImpl: {
description: 'CustomInterface Implementation',
interfaces: [graphQL.reference('CustomInterface')],
fields: {
query: {
type: graphQL.list(graphQL.GraphQLString),
args: {
filter: graphQL.reference('CustomFilterInput')
}
},
extraField: {
type: graphQL.GraphQLString,
}
}
}
}
According to GraphQL specification an implementation of an interface must implement all fields of the interface.
