@HugoTrentesaux pour le moment ton instance Squid ne propose pas de subscription, mais il suffit de les activer avec une option côté serveur:
OpenReader supports GraphQL subscriptions via live queries. To use these, a client opens a websocket connection to the server and sends a
subscriptionquery there. The query body is then repeatedly executed (every 5 seconds by default) and the results are sent to the client whenever they change.
To enable subscriptions, add the additional --subscriptions flag to the squid-graphql-server startup command. The poll interval is configured with the --subscription-poll-interval flag. For details and a full list of available options, run
npx squid-graphql-server --help
