req. 'connection' is @deprecated — since v13.0.0 - Use socket instead

Question

I am trying to get the client's IP using Express:

const ip = req.headers['x-forwarded-for'] || req.connection.remoteAddress;

When mouseover the req.connection in VS Code I get a warning:

(property) IncomingMessage.connection: Socket
@deprecated — since v13.0.0 - Use socket instead.

'connection' is deprecatedts(6385)

How to implement the 'socket instead' / what is the proper way to find the IP of the client?

Answer 1

You have just to replace req.connection.remoteAddress with req.socket.remoteAddress in the http package documentation request.connection is flagged as Deprecated and It's an alias of request.socket, you can directly use request.socket

request.socket is an instance of net.Socket you check all available methods here

Answer 2

Just type req.socket.remoteAddress instead and you are good to go!
