_Note: If used as a function, this will be used to modify resolvers AND the schema. For example, if a `foo` header is set, then the resolver call will append the `foo` header, and the `foo` parameter will be removed from the GraphQL schema. In `resolver_builder.ts`, the function will be called with all arguments, but in `schema_builder.ts`, only the `method`, `path`, and `title` will be provided (because `resolverParams` and `generatedRequestOptions` are only available during execution). Therefore, for query, path, header, and cookie parameters, a value must be provided without `resolverParam` and `generatedRequestOptions` or else the schema will not have the right parameters._

- `requestOptions` (type: `object` | `function`, default: `{}`): Additional [options](https://github.com/request/request#requestoptions-callback), provided by the [`Request` module](https://github.com/request/request), that can be used to configure the HTTP calls that powers the generated GraphQL resolvers. A common use case for this option is to add headers or query string parameters to every request or to set up a web proxy with the `proxy` field. Parameters defined in the OpenAPI Specification and set by this option will be ignored by OpenAPI-to-GraphQL. If `requestOptions` is used as a function, the following parameters will be exposed per request: the operation's `method`, the operation's `path`, the API `title`, and `resolverParams` (the [GraphQL resolver's parameters](https://graphql.org/learn/execution/#root-fields-resolvers)). The function should return an [options](https://github.com/request/request#requestoptions-callback) object. _Note: If used as a function, this will be used to modify resolvers AND the schema.

- `connectOptions` (type: `object`, default: `{}`): Allows to override or add options to the PubSub connect object used to make publish/subscribe to the API backend, e.g. setup the web proxy to use.

import { RequestOptions } from './types/options';

declare type GetSubscribeParams<TSource, TContext, TArgs> = {

connectOptions: ConnectOptions;

declare type GetPublishResolverParams<TSource, TContext, TArgs> = {

operation: Operation;

responseName?: string;

data: PreprocessingData<TSource, TContext, TArgs>;

declare type GetResolverParams<TSource, TContext, TArgs> = {

responseName?: string;

requestOptions: RequestOptions<TSource, TContext, TArgs>;

export declare function getPublishResolver<TSource, TContext, TArgs>({ operation, responseName, data }: GetPublishResolverParams<TSource, TContext, TArgs>): GraphQLFieldResolver<TSource, TContext, TArgs>;
