code: function getPathFromRequest (req, useBase, usePathAsTransactionName) {
    // Static serving route
    if (req[symbols.staticFile]) {
      return 'static file'
    }
  
    var path = getStackPath(req)
    var route = routePath(req.route)
  
    if (route) {
      return path ? join([ path, route ]) : route
    }

    // Enable usePathAsTransactionName config
    if (usePathAsTransactionName) {
      const parsed = parseUrl(req)

  }
docs: This function is also able to extract the path from a Restify request as it's storing the route name on req.route.path as well
