10093 :: noob question exception and await

• FabienPRI (orginal) [2023-04-12T17:06:17+02:00] view original

  Hi,

  Let say I have this code :

  proc handler(req: Request) {.async.} =
    if req.url.path == "/hello-world":
      let msg = %* {"message": "Hello World"}
      let headers = newHttpHeaders([("Content-Type","application/json")])
      await req.respond(Http200, $msg, headers)
    else:
      await req.respond(Http404, "Not Found")
  Run

  if there is an exception in respond for any reason, I can try except the await, is there any gain to discard req.respond(Http200, $msg, headers) because I do not care of the result, does it change something?

  you should check the asyncdispatch docs

  for async logic its recommended to use yield / asyncCheck instead of discard / try, except

  per your specific question, asyncCheck should be preferred
