Describe the bug The resolver type for a type that contains a type that contains a union of types that are mapped, drops knowledge of the mapped type.
That a mouthful, but here is a minimal reproduction:
To Reproduce LIve Code Sandbox: https://codesandbox.io/s/inspiring-shape-ts0t5
- My GraphQL schema:
type Query {
feed: FeedConnection!
}
type FeedConnection {
edge:FeedEdge
}
type FeedEdge {
node: FeedNode
}
union FeedNode = PostFeedNode | PhotoFeedNode
type PostFeedNode {
text:String
}
type PhotoFeedNode {
url:String
}
-
My GraphQL operations: N/A
-
My
codegen.ymlconfig file:
schema: schema.graphql
generates:
types.ts:
plugins:
- typescript
- typescript-resolvers
config:
mappers:
PostFeedNode: ./model#PostFeedNodeModel
PhotoFeedNode: ./model#PhotoFeedNodeModel
Expected behavior
The resolver type should be:
FeedConnection:ResolverTypeWrapper<Omit<FeedConnection, 'edge'> & { node?: Maybe<ResolversTypes['FeedEdge']> }>;
But the generated type is:
FeedConnection: ResolverTypeWrapper<FeedConnection>;
