Express allows to do content-negotiation. Using response.format function, it can perform content-negotiation on the Accept HTTP header on the request object, when present.
It uses request.accepts() to select a handler for the request, based on the acceptable types ordered by their quality values. If the header is not specified, the first callback is invoked. When no match is found, the server responds with 406 “Not Acceptable”, or invokes the default callback.
