Cancelling Graphql subscriptions

Help

Based on this topic: Is it possible to cancel Graphql subscriptions?.

I was using useSubscription, but when I came across the topic above, I changed it to the client.subscribe() implementation to manually unsubscribe.

However, after unsubscribing using subscription.unsubscribe();, I noticed that the web socket is still opened and still listening to events. So my question is, how do I disconnect the observer?

I am guessing it should look something like this: observer.disconnect();.

Hi! Your WebSocketLink instance exposes a subscriptionClient object that you can call close() on:

const webSocketLink = new WebSocketLink({
    uri: '...',
    options: {},
});

webSocketLink.subscriptionClient.close();

@mindnektar Thank you for your response, I am using AbsintheSocket, and PhoenixSocket for my connection, so here is how it looks:

const absintheSocketLink = createAbsintheSocketLink(
    AbsintheSocket.create(
         new PhoenixSocket('ws://auth.localhost.test/socket', {
              params: {params},
         })
    )
);

const AccountSocketClient = new ApolloClient({
  link: absintheSocketLink,
  cache: new InMemoryCache(),
});

AccountSocketClient is the apollo client I use to subscribe.

Have you tried AbsintheSocket.cancel? Otherwise I’d suggest asking the maintainers of that library, they can probably help. :slight_smile:

Yes, I tried that. But, unfortunately, it didn’t seem to work.
