how to use request module to download, and then upload file without intermediate file

I want to download a image file to server first, then upload this file to other server.

Answer 1

Following the request documentation, you can use

request.get(sourceUrl).pipe(request.post(targetUrl))

in this scheme, the data will flow from sourceUrl to targetUrl but will not need to be saved in a temporary file on the server.

cf https://github.com/request/request#streaming for more details.
