Parsing GQL -> TS enum member descriptions

[mccauleyp]

I have some GraphQL enums where the values are used as menu items in a drop down menu and the descriptions are used as tooltip text to provide information about each item.

Currently I'm running a __type query when the page loads, but I'd like to instead use the generated TypeScript types so that this query isn't needed and so that introspection queries can be disabled generally. The GraphQL enums converted to TS look like:

export enum MyEnum {
  /** Member 1 description */
  Member1 = 'MEMBER1',
  /** Member 1 description */
  Member2 = 'MEMBER2',
}

I'm looking for advice on how to pull out the description fields. Is there a way to do this with graphql-code-generator that perhaps maps GraphQL enums to a different type than an a TS enum or puts the descriptions in a separate object? Or perhaps I could parse the description comment strings out of the generated code file (although that feels a bit hacky)?

I'm using the following versions:

        "@graphql-codegen/cli": "^2.16.1",
        "@graphql-codegen/typescript": "^2.8.5",
        "@graphql-codegen/typescript-operations": "^2.5.10",
        "@graphql-codegen/typescript-react-apollo": "^3.3.7",

With the following config:

import { CodegenConfig } from '@graphql-codegen/cli';

const config: CodegenConfig = {
    schema: 'http://localhost:8000/graphql/',
    documents: ['src/gqlOperations/*'],
    generates: {
        './src/generated-types.ts': {
            plugins: ['typescript', 'typescript-operations', 'typescript-react-apollo'],
            config: {
                scalars: {
                    UUID: 'string',
                    DateTime: 'string',
                    JSON: 'unknown',
                },
            },
        },
    },
};

export default config;

I suppose you can try to write a custom plugin where during the visit you can export strings as a type yourself?
