      const qs = createQueryString({ jwt });
      socket = new WebSocketClient(`${config.wsServerUrl}/${qs}`);

      socket.onmessage = event => {
        const { type, payload, meta: socketMeta } = JSON.parse(event.data);

        const meta = {
          ...socketMeta,
          currentUser: selectCurrentUser(store.getState())
        };

        if (
          type === Event.SOCKET_REGISTRATION.SUCCESS &&
          payload.user.id === meta.currentUser.id
        ) {
          store.dispatch(isUserFollowing(meta.eventId));
