Support for Args and related module types in GraphQL Module Resolvers

[tvvignesh]

When I use the graphql-modules preset, I don't get typings like MutationCreateAuthMethodsArgs in the module generated file but I do get it in the overall codegen file

For eg: I have this in overall codegen file:

/** Auth Method Mutations */
export type MutationCreateAuthMethodsArgs = {
  input?: Maybe<Array<Maybe<CreateAuthMethodsInput>>>;
};

But not in the module file. I just have this:

export type createAuthMethodsInput = Pick<Types.CreateAuthMethodsInput, DefinedInputFields['createAuthMethodsInput']>;

I use the type in the provider like this:

async create(context: GraphQLModules.Context, args: GQLTypes.MutationCreateAuthMethodsArgs) {
}

but not able to do that now.

The typing works well in resolvers, but this is what I do in my resolver:

createAuthMethods: async (_parent, args, context: GraphQLModules.Context) => {
    let result = await context.injector.get(AuthMethod).create(context, args);
    return result;
  },

Thanks. Will use the global typed file as of now.

Also, while not related to this issue the context is not typed when using graphql modules preset. I get the type as any. Screenshot below:

One more thing which I wanted to share is that, I use DeepPartial to return a portion of the schema from my functions and I have it configured like this:

- add:
                  placement: prepend
                  content: >
                    import { DeepPartial } from 'utility-types';
            config:
              defaultMapper: DeepPartial<{T}>

Currently the import gets added to both the global and module generated types file (even though its not used in the module types file) because of which TS throws error (I run TS in strict mode)

Currently, I am overcoming this with a ts-ignore like this which is totally fine. But just thought I should let you know (sometime in the future, the ability to prepend content differently into the module types file and global types file would make sense:

content: >
   // @ts-ignore

  import { DeepPartial } from 'utility-types';

PS: This is not a priority.
