relay-link-ws v1.0.3

title: relay-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 "relay-link-ws";
import { SubscriptionClient } from "relay-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 to
• options: a set of options to pass to a new Subscription Client
• webSocketImpl: a custom WebSocket implementation

By default, this link uses the relay-transport-ws library for the transport.
