GraphQL Live Queries with live directive

Huh, I've been thinking about a very similar service that does not require a dependency on GraphQL — https://poll2hook.com/

You can define a query on any API, be it GraphQL or REST, and a jq query to extract events, and you are good to go. I wonder if this @live directive is implemented with polling?

This `@live` directive implementation uses server-sent events to send messages to the client with any changes that happen on the server in the format of https://jsonpatch.com

This means users don't need to poll to fetch all the data again but only get the data that changes. Poll2Hook looks great though, certainly a great solution if the service you're using doesn't have something native built-in.

You could also implement live queries using polling and the E-Tag, If-None-Match header (https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/If...).

We experimented with something similar on a customer project where having a long-lived HTTP connection was not possible.
