Foxx: How not having to define queryParams up front?

I am getting myself up to speed with ArangoDB and Foxx, and so far the experience has been great! I have however one question:

For the Foxx router one can specify queryParams, for instance /graph/nodes?eyes=blue&hair=blond.

What bothers me though is that I am forced (or at least, after several attempts I have such impression) that I have to hard code that I am expecting query params of eyes and hair.

Is this indeed true? And if yes, is there a work around? For me this is a bit strange within the context of nosql and being able to store documents with whatever attributes one wants in a collection.

I'd rather have that I can e.g. fetch the whole part of the URL after ?, do a split("&") on the string and catch whatever was part of the request.

Is there a way to do this within the Foxx framework?

Any help would be greatly appreciated!

I'm not sure why you think you are forced. The only distinction should be that query params specified as queryParam will be validated (if a schema is provided) and documented.

You should be able to just use req.queryParams to access additional query parameters:

router.get(function (req, res) {
  res.json(req.queryParams);
})
.queryParam('documented', joi.number().optional());

GET /?documented=23 -> {"documented": 23}

GET /?more=42 -> {"more": "42"}

This assumes you are using ArangoDB 3.0 and not running a Foxx services written for 2.8 in legacy compatibility mode (i.e. you're using things called routers, not things called controllers).

Ok, I managed to find my solution myself, by using var query_params = req.originalUrl.split("?")[1];. Then I get the string that I wanted with raw query parameters. From the manual:

originalUrl: string

Root-relative URL of the request, i.e. path followed by the raw query parameters, if any.
