Allows to modify OpenAPI Specification autogenerated by plumber.

pr_set_api_spec(pr, api)

Arguments

pr

A Plumber API. Note: The supplied Plumber API object will also be updated in place as well as returned by the function.

api

This can be

  • an OpenAPI Specification formatted list object

  • a function that accepts the OpenAPI Specification autogenerated by plumber and returns a OpenAPI Specification formatted list object.

The value returned will not be validated for OAS compatibility.

Value

The Plumber router with the new OpenAPI Specification object or function.

Details

Note, the returned value will be sent through serializer_unboxed_json() which will turn all length 1 vectors into atomic values. To force a vector to serialize to an array of size 1, be sure to call as.list() on your value. list() objects are always serialized to an array value.

Examples

if (FALSE) { # Set the API Spec to a function to use the auto-generated OAS object pr() %>% pr_set_api_spec(function(spec) { spec$info$title <- Sys.time() spec }) %>% pr_get("/plus/<a:int>/<b:int>", function(a, b) { a + b }) %>% pr_run() # Set the API Spec using an object pr() %>% pr_set_api_spec(my_custom_object) %>% pr_get("/plus/<a:int>/<b:int>", function(a, b) { a + b }) %>% pr_run() }
