progress event about send HOT 13 CLOSED

I'm going to close this as stale. Unless Node.js adds some kind of progress events to the fs streams, it is probably not possible.

Because to open a feature request in Node.js, you need to also champain it and even implement it yourself as a pull request if you cannot convince a maintainer to do it. You can read more about how feature requests work in their guidelines. I have no bandwidth to do such a thing, unfortunately.

But anyone who does is welcome to do so.

from send.

No, there is not a way to do this currently that I am aware of.

from send.

I solve it now by registering the stream event then register data event for stream like the following:

send(...)
.on('stream', stream => {
  stream.on('data', chunk=> {
      // calculate progress here
  })
})
.pipe(...)

I tried to use progress-stream to detect progress but not works for me. If there is a way to use this library with send library please tell me how.

from send.

Ah, yea, I was going to suggest something similar, but that has one main issue: I think that registering on a stream data listener may turn off the back pressure feature of Node.js, which can balloon your app's memory usage. It would also be the progress read of your local fs, and not the progress of sending to the end client.

from send.

So how can I do that? please help me

from send.

Just looking at progress-stream module I don't think it's possible to work without adding some new support to it to support progress on http responses from server pov.

I don't know the solution, or I would have posted already :) and now I'm on mobile phone, so cannot try anything out until perhaps tomorrow at the earliest.

Ok thank you, but please one last question if I use through2 library so pipe data to the library then pipe it to response it has an effect on the back pressure like registering data event for stream ?

from send.

I'm not familiar with the through2 lib, so would need some time to learn it and test it and get the answer for you.

from send.

Ok thank you very much

Hello, is there any solution till now ?

I'm going to close this as stale. Unless Node.js adds some kind of progress events to the fs streams, it is probably not possible.

Then why not open an issue for Node?
