how to use type-graphql subscription

[ceddybi]

Hi @hansottowirtz super awesome work!

I was trying to get subscriptions working with type-graph schema, but the resolveSubscription doesn't get the topic and filter

Can i provide the example repo ?

when you're publishToConnections, why do you have to execute the schema knowing the handler has been modified, why not just return the payload to the websocket as is like you commented here

// execution of subscription with payload as the root (can be modified within the resolve callback defined in schema)
// will return the payload as is by default
const payload = await execute({
  schema: schema,
  document: parse(sub.subscription.query),
  rootValue: eventPayload,
  contextValue: graphqlContext,
  variableValues: sub.subscription.variables,
  operationName: sub.subscription.operationName,
});

// transform it into ws message (id is not specific to connection but to subscription)
const message: NextMessage = {
  id: sub.id,
  type: MessageType.Next,
  payload,
};

why not just send the payload as is without the execute, i think the execute is not effective.

const message: NextMessage = {
  id: sub.id,
  type: MessageType.Next,
  payload: eventPayload
};
