Question: is it possible to include the graphql type in the scalar "serialize" function

[codecvlt]

In the graphql-relay-js library they have a function to declare a GlobalID for a type.

export function globalIdField(
typeName?: ?string,
idFetcher?: (object: any, info: GraphQLResolveInfo) => string
): GraphQLFieldConfig {
return {
name: 'id',
description: 'The ID of an object',
type: new GraphQLNonNull(GraphQLID),
resolve: (obj, args, info) => toGlobalId(
typeName != null ? typeName : info.parentType.name,
idFetcher ? idFetcher(obj, info) : obj.id
)
};
}

This is used by relay to ensure you don't expose raw database ids to the public, and also to determine a node type based on it's id (since the id is hashed along with it's type).

Is there anyway to check the graphql type for an object in the serialize function of a scalar definition, so that i can encode these ID with their appropriate type?

e.g
scalar GlobalID

GlobalID: {
serialize(id, nodeType) {
return toGlobalId(nodeType, id);
}
}

Thanks!

Not currently, but I've opened a ticket on graphql-js to allow this functionality: graphql/graphql-js#306

@codecvlt from the comments in the PR I mentioned above, it doesn't look like this will be a possibility, you can check the explanation there for more info.
