How to download a large file from a distant server?

Question

Node.js

Hello.
I write for a web service on nodejs.
The task is to download a file from a remote server and send it immediately to the client, without saving it to the server disk.
The client sends the file id in the database to the server, I find the url where the file is located and start downloading.
The general principle of downloading, I think, will be the following: we start downloading and periodically send what has been downloaded to the client until the file runs out.
How can this be done?

You need to open a stream for downloading from a remote server and write it to the request stream
The `request` module allows you to receive data from the server in the form of a stream.
With the use of streams, the general principle is exactly as described. But it is already implemented, you just need to use it correctly.
