emitSchemaFile in federation

[JipSterk]

The output of emitSchemaFile is different then when i use an introspection tool to download the schema like rover.

for instance i have an entity in the schema User

My model looks something like this:

@Directive(`@key(fields: "id")`)
@ObjectType()
export class User {
  @Field(() => ID)
  id: string;
}

in the schema generated by type-graphql it would look something like this:

directive @extends on INTERFACE | OBJECT

directive @external on FIELD_DEFINITION | OBJECT

directive @key(fields: String!) on INTERFACE | OBJECT

directive @provides(fields: String!) on FIELD_DEFINITION

directive @requires(fields: String!) on FIELD_DEFINITION

type User {
  id: ID!
}

type Query

the directives are from the graphql and @apollo/federation packages

but if i download the schema via introspection with rover with rover subgraph introspect http://localhost:4000/graphql > schema.gql

the schema would look like this:

type User @key(fields: "id") {
  id: ID!
}

type Query

if providing a repo would help shed some light on this i would happily provide it.

Please read the docs carefully, it's written there why the emitted schema does not contain directives on types and fields.

I've prepared docs to not have to answer to such questions and use my time in a more productive manner 😉

ouch... im sorry i asked. next time ill read the docs more thorough 😅

For directives and federation purposes you can import { printSchema } from "@apollo/federation";
