This link is particularly useful to use GraphQL Subscriptions, but it will also allow you to send GraphQL queries and mutations over WebSockets as well.
;;const GRAPHQL_ENDPOINT = "ws://localhost:3000/graphql";const client = GRAPHQL_ENDPOINTreconnect: true;const link = client;
WS Link takes either a subscription client or an object with three options on it to customize the behavior of the link. Takes the following possible keys in the configuration object:
uri: a string endpoint to connect to
options: a set of options to pass to a new Subscription Client
webSocketImpl: a custom WebSocket implementation
By default, this link uses the subscriptions-transport-ws library for the transport.
