title: apollo-link-ws description: Send GraphQL operations over a WebSocket. Works with GraphQL Subscriptions.
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.
import { WebSocketLink } from "apollo-link-ws";
import { SubscriptionClient } from "subscriptions-transport-ws";
const GRAPHQL_ENDPOINT = "ws://localhost:3000/graphql";
const client = new SubscriptionClient(GRAPHQL_ENDPOINT, {
reconnect: true
});
const link = new WebSocketLink(client);
Options
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 tooptions
: a set of options to pass to a new Subscription ClientwebSocketImpl
: a custom WebSocket implementation
By default, this link uses the subscriptions-transport-ws library for the transport.
