Is it possible to check if a system is on LAN vs WiFi via nodejs?

Question

Are there any packages for node that can determine if a PC is on a LAN vs Wifi connection?

I have gone through the node docs and it doesn't appear there is a native node module. (https://nodejs.org/api/os.html)

Could not find anything in NPM that could determine this either.

Remember you can run any bash command you want using exec.

So you can do something along the lines of

const util = require('util');
const exec = util.promisify(require('child_process').exec);

async function main() {
  const { stdout, stderr } = await exec('tail -n+3 /proc/net/wireless | grep -q .');

 if (stdout) { // wirelesss }
}

main()

Adapted: determine if connection is wired or wireless?
