Integrating WebSockets for GraphQL subscriptions in SvelteKit application with Apollo Server

[gwerneckp]

I'm trying to integrate GraphQL subscriptions in my SvelteKit application using Apollo Server. I have successfully set up the basic GraphQL queries and mutations, but I'm struggling with implementing subscriptions.

In SvelteKit, the underlying server setup and management are abstracted away, and we don't have direct access to the HTTP server object.

I was expecting to find a way to integrate the WebSocket functionality required for subscriptions within the SvelteKit framework, or an alternative approach to enable GraphQL subscriptions in my SvelteKit application using Apollo Server.
