GraphQL Subscriptions

While GraphQL queries will subscribe to changes from locally issued mutations or live updates, you may also want to subscribe to updates that are pushed by the server. In this situation you can use a GraphQL subscription instead of a GraphQL query. GraphQL subscriptions require a different implementation on the server to support initiating remote updates.

const userSubscription = graphQLSelector({
  key: 'UserSubscription',
  environment: myEnvironmentKey,
  query: graphql`
    subscription UserSubscription($id: ID!) {
      user(id: $id) {
        name
        address
      }
    }
  `,
  variables: ({get}) => ({id: get(currentIDAtom)}),
  mapResponse: data => data.user,
});
