Generated TS operation type is not using types from schema

[tsareg]

Imagine I have following query:

import { gql } from 'graphql-tag';

export const CarsCompaniesWithRankQuery = gql`
  query CarsCompaniesWithRank($cwrInput: RentalCarsCompaniesWithRankInput!) {
    cars {
      companiesWithRank(input: $cwrInput) {
        id
        name
        logoUrl
        cc1
      }
    }
  }
`;

and I have following codegen.yml:

overwrite: true
schema: "./schema.graphql"
documents: "./src/**/*.{ts,tsx,js,jsx,graphql,gql}"
generates:
  src/types.ts:
    plugins:
      - "typescript"
      - "typescript-operations"

In this scenario I would get following types generated by typescript plugin (skipping other types for brevity):

export type CarsQueries = {
  __typename?: 'CarsQueries';
  recommendedPickupLocations: Array<Maybe<RentalCarsPickupLocation>>;
  companiesWithRank: Array<Maybe<RentalCarsCompanyWithRank>>;
};

export type RentalCarsCompanyWithRank = {
  __typename?: 'RentalCarsCompanyWithRank';
  id?: Maybe<Scalars['Int']>;
  name?: Maybe<Scalars['String']>;
  logoUrl?: Maybe<Scalars['String']>;
  cc1?: Maybe<Scalars['String']>;
};

Then typescript-operations plugin generates following type for my query:

export type CarsCompaniesWithRankQuery = { 
  __typename?: 'Query', 
  cars: { 
    __typename?: 'CarsQueries', 
    companiesWithRank: Array<Maybe<{ 
      __typename?: 'RentalCarsCompanyWithRank', 
      id?: Maybe<number>, 
      name?: Maybe<string>, 
      logoUrl?: Maybe<string>, 
      cc1?: Maybe<string> 
    }>> 
  } 
};

Basically it's repeating the type definition for RentalCarsCompanyWithRank. Ideally I'd love to see the plugin generating following instead:

export type CarsCompaniesWithRankQuery = { 
  __typename?: 'Query', 
  cars: { 
    __typename?: 'CarsQueries', 
    companiesWithRank: Array<Maybe<RentalCarsCompanyWithRank>> 
  } 
};

Am I missing anything? Or it's expected situation?

typescript-operations picks the fields you selected in the operations so it is not always companiesWithRank: Array<Maybe<RentalCarsCompanyWithRank>> . If you want to see how it picks it up, you can add preResolveTypes: false.

Oh, i think i finally got it! Thanks!
