How can I check if the VPN is turned off in a React application?

import React from "react";
import { Offline, Online } from "react-detect-offline";
export default function DropDown() {
return (
    <>
    <Online>Only displayed when connected to the internet</Online>
    <Offline>Only shown when offline (surprise!)</Offline>
    </>
  );
}

This code currently detects online and offline statuses only. I would like to enhance it to also detect when VPN connection is turned off, displaying "offline" and detecting when VPN is on, displaying "online".

Answer №1

It seems like you're in the process of creating an internal website that can only be accessed while connected to a VPN. One way to accomplish this is by sending a 'ping' request to an internal resource. If the request fails, you can then indicate that the site is offline.

You can also try making a GET or OPTIONS http call, and if it doesn't succeed, it indicates that the VPN connection is not established. While this method may not be perfect for detecting VPN connectivity, implementing it directly in the browser presents challenges.
