Poll interval or refetch on search GQL schema in GraphIQL

[Moumouls]

Is your feature request related to a problem? Please describe.

TLDR: this feature was supported on the Playground

The Schema seems to be fetched only once. But schema can change and evolve.

Describe the solution you'd like

Add an option to add a poll interval and/or trigger a introspection refetch when a user searches in the docs.

Describe alternatives you've considered

Reload the whole web page.

Additional context

We could also add reload docs button similar to Altair

@saihaj from my Playground knowledge you are right.

On the playground, if the "polling" option is not activated, the URL field display a reload button to let the user reload the schema without reloading the whole page.

Any update on this? I need this feature at Pylon so that the playground updates while developing the schema.

On a second thought polling isn't optional for my use case. Is it possible to implement SSE?

Workflow:

1. The GraphiQL listens for changes using SSE (e.g. /graphql/live)
2. The server watches for changes (for example on the file location of the schema file, or just checks if the schema object changes)
3. The server triggers a event
4. The client re-introspects the schema.

This should only be a development feature and not be included in production.

Why not polling?

1. I want instant feedback
2. I do not want to spam my console with /graphql requests during development
