Using serializer

[thfuchs]

I'm currently trying to implement the unboxed serializer for jsonlite::toJSON.

Is this possible with sealr?

I tried

pr$handle(
  "GET",
  "/secret",
  function (req, res) {return("Access to route requiring authentication was successful.")},
  serializer = "unboxedJSON"
)

which results in status 500, message [1] "ERROR: Serializers must be closures: 'unboxedJSON'" when trying to call this with httr
