Apollo Smart Subscription

The easiest way to bring live data to your UI is using the useSubscription() method from @vue/apollo-composable. Each subscription created with useSubscription() in a component results in the creation of a reactive subscription object.

One thing to note, subscriptions in vue-apollo are just listeners, they don’t request any data when first connected, but only open up a connection to get new data. But in Hasura GraphQL Engine, subscriptions are live queries. The initial request gives back data, if any, for the subscription.
