Yet another SSDP implementation for node.js

import os from 'os'
import type { NetworkInterfaceInfo } from 'os'

export function findAllInterfaces (includeIPv4: boolean, includeIPv6: boolean): NetworkInterfaceInfo[] {
  const output: NetworkInterfaceInfo[] = []
  const networkInterfaces = os.networkInterfaces()

  Object.values(networkInterfaces).forEach(info => {
    if (info == null) {
      return
    }

    info.forEach((iface) => {
      if (iface.internal) {
        return
      }

      if (iface.family === 'IPv4' && includeIPv4) {
        output.push(iface)
      }

      if (iface.family === 'IPv6' && includeIPv6) {
        output.push(iface)
      }
    })
  })

  return output
}
