@graphql-tools/stitch doesn't preserve @oneOf #1404
Description
Hey guys, thanks for maintaining the tools herein.
We've noticed that stitchSchemas doesn't seem to preserve @oneOf. Repro:
import {stitchSchemas} from '@graphql-tools/stitch';
import {buildSchema, printSchema} from 'graphql';
const schemaSrc = `
type Query {
findPerson(in: FindPersonInput): Person
findPersonById(id: String): Person @deprecated(reason: "use findPerson")
}
type Person {
Name: String
ID: String
}
input FindPersonInput @oneOf {
byId: String
byName: String
}
`;
const schema = buildSchema(schemaSrc);
const stitchedSchema = stitchSchemas({subschemas: [schema]});
console.log(printSchema(schema));
console.log('-----------')
console.log(printSchema(stitchedSchema));Output:
type Query {
findPerson(in: FindPersonInput): Person
findPersonById(id: String): Person @deprecated(reason: "use findPerson")
}
type Person {
Name: String
ID: String
}
input FindPersonInput @oneOf {
byId: String
byName: String
}
-----------
type Query {
findPerson(in: FindPersonInput): Person
findPersonById(id: String): Person @deprecated(reason: "use findPerson")
}
type Person {
Name: String
ID: String
}
input FindPersonInput { # <--- missing @oneOf!
byId: String
byName: String
}Any reason why this is the case? I've included a @deprecated as a demo of another built-in directive that seems to work out of the box.
Cheers!
