Ktor subscription example (?)

[Mautriz]

Hey there, can someone help me understanding how to implement subscriptions with websockets on ktor or make a small example? I wanted to use kotlin/graphql in a new project and subscriptions are whats blocking me (I'm new to kotlin btw)

We do not have an example in Ktor for subscriptions as there are many implementation details that are specific for each server. If you take a look at the Spring code you will see we are implementing the subscriptions-transport-ws protocol

You could also implement the graphql-ws protocol

@Mautriz did you find how to use subscriptions? @smyrick you still don't have an example for when graphql-ws protocol is used?
