app.get(\"/firstService/:query\", function(req,res){

If you have a lot of middleware on your route, you can benefit from spreading:

const router = express.Router();

const myMiddleware = [
    authenticationMiddleware(),
    validityCheckMiddleware(),
    myActualRequestHandler
];

router.get( "/foo", ...myMiddleware );
router.get( "/v1/foo", ...myMiddleware );
