SocketError

The SocketError has a .socket property which holds socket metadata:

interface SocketInfo {
  localAddress?: string
  localPort?: number
  remoteAddress?: string
  remotePort?: number
  remoteFamily?: string
  timeout?: number
  bytesWritten?: number
  bytesRead?: number
}

Be aware that in some cases the .socket property can be null.
