re: Phoenix Live View Debounce VIEW POST



Wouldn't the

socket = socket
  |> assign(:results, search_results(socket.assigns.query))
  |> assign(:loading, false)

make the debounce do its job better?

Argument being that expensive searches might last 1-200ms and in the meantime a new keystroke would appear


Thank you!

Actually the two implementation are the same because the assign function does not change socket in place, but build a new copy. The new socket is sent to the live view only when handle_info function completes.

Search_results in my implementation is a synchronous call and blocks the process until it returns. If search_results takes a very long time what happens is that the updated query terms queue in the mailbox of the process until the search_results function returns. You can see it very well if you put something like Process.sleep(10_000) inside the search_function.
