Currently express-resource uses the :format parameters for matching requested resource format (.xml, .json, etc).

In addition to this, it would be nice to support the HTTP Accept headers. connect-conneg provides a parser for them that organizes the requested formats by preference.

This can already be used with express-resource, but requires some boilerplate. First you need to add the conneg middleware:

server.use require('connect-conneg').acceptedTypes

And then handle the types in the default content negotiation handler:

default: (req, res, next) ->
  for type in req.acceptableTypes
    if this.html and type is 'text/html'
      return this.html req, res, next
    if this.json and type is 'application/json'
      return this.json req, res, next

It would be very useful if the default implementation of default did this, instead of falling back to 406 error.

but yup I agree this would be nice to have

@visionmedia great! It would be good to support the new Express 3x feature (req.accepted) and connect-conneg (req.acceptableTypes).

Want a pull request?
