// to worry about constantly pulling in JS updates.
    if (options.uiDirs) {
      if (typeof options.uiDirs === 'string') {
        router.use(loopback.static(options.uiDirs));
      } else if (Array.isArray(options.uiDirs)) {
        options.uiDirs.forEach(function(dir) {
          router.use(loopback.static(dir));
        });
      }
    }

    // File in node_modules are overridden by a few customizations
    router.use(loopback.static(STATIC_ROOT));

    // Swagger UI distribution
    router.use(loopback.static(SWAGGER_UI_ROOT));
  }

  return router;
