Response #14

It would be great enhancement to be able to define a custom function which is called when rate limit is exceeded, instead of being limited to: if (shouldLimit) { res.status(429).send('Rate limit exceeded'); return; }

For example, when using a Swagger for building APIs and want that they produce application/json the res.status(429).send('Rate limit exceeded'); returns error.

Would it be possible to add such enhancement, to be able to respond rate limit exceeded in different format, e.g. in JSON such as res.status(429).json({message: 'Rate limit exceeded'}); ?
