awaiting for procedure & logging the response.

Hi, I was wondering if there is a way to handle the return object via the post-middleware's? I know we could do something like,

const logMiddleware = t.middleware(async ({ ctx, next }) => {
   const res = await next();
   // insert logging here
   return res;
);

const logMiddleware = t.middleware(async ({ ctx, next }) => {
   const res = await next();
   // insert logging here
   return res;
);

However, I want to access the returned result with an event name & log it. This event name could be returned by the procedure itself as one of the key's of

res

res

. The problem is I can't access the

res

res

object as it's of type

MiddlewareResult

MiddlewareResult

& is the whole request itself that is returned from a procedure's query/mutation. How should I go about solving this? Is there a way I could destruct the data returned from

next()

next()

and wrap it in a defined type say something similar to,

type Response = {
  event: "requested_data"; // res.response.type
  request: { ip: res.req.headers.forwarded, ua: ...},
  time: 18214931949,
  data: { type: "query/mutation", path: "procedure path", ctx: res.ctx, input: res.input, response: res.response.message  
 },
}

type Response = {
  event: "requested_data"; // res.response.type
  request: { ip: res.req.headers.forwarded, ua: ...},
  time: 18214931949,
  data: { type: "query/mutation", path: "procedure path", ctx: res.ctx, input: res.input, response: res.response.message  
 },
}

& fill in the fields with my

res

res

object. log the response to my db & return

res.reponse

res.reponse

to my client.
