Not sure where to report issue for npm package in itself so am reporting here. The following is the type file on the latest npm install i.e. ``` npm install --save express-graphql ``` via. `renderGraphiQL.d.ts` ``` export interface GraphiQLOptions { /** * An optional GraphQL string to use when no query is provided and no stored * query exists from a previous session. If undefined is provided, GraphiQL * will use its own default query. */ defaultQuery?: string; /** * An optional boolean which enables the header editor when true. * Defaults to false. */ headerEditorEnabled?: boolean; } ``` Looking at the GitHub repo it seems the additional `subscriptionEndpoint?` field was added for subscription report. Versioning on npm says `0.12.0` which matches with GitHub versioning but there seems to be a discrepancy and am getting some Typescript errors when trying to use subscriptions because of it. Seems like npm and GitHub are not in sync.
