How to handle big file upload?

[devalexqt]

For express/node we have req stream pipe to file on disk, so do we have this option in deno?

As far as I know, deno doesn't have the stream yet. I'm also looking for how to upload the file...
If you found the way, please let me know too.

  assert(rs.locked);
  assert(ws.locked);
