Plumber Serializers — serializer

Serializers are used in Plumber to transform the R object produced by a filter/endpoint into an HTTP response that can be returned to the client. See here for more details on Plumber serializers and how to customize their behavior.

Arguments

...	extra arguments supplied to respective internal serialization function.
auto_unbox	automatically `unbox` all atomic vectors of length 1. It is usually safer to avoid this and instead use the `unbox` function to unbox individual elements. An exception is that objects of class `AsIs` (i.e. wrapped in `I()`) are not automatically unboxed. This is a way to mark single values as length-1 arrays.
type	The value to provide for the `Content-Type` HTTP header.
version	the workspace format version to use. `NULL` specifies the current default version (3). The only other supported value is 2, the default from R 1.4.0 to R 3.5.0.
ascii	a logical. If `TRUE` or `NA`, an ASCII representation is written; otherwise (default) a binary one. See also the comments in the help for `save`.
