create_server_yml: Create a _server.yml file to describe your API
Description
While you can manually create a plumber2 API by calling api(), you will
often need to deploy the api somewhere else. To facilitate this you can
create a _server.yml that encapsulates all of your settings and plumber
files. If you call api() with a path to such a file the API will be
constructed according to its content.
path to files and/or directories that contain annotated plumber
files to be used by your API
path
The folder to place the generated _server.yml file in
constructor
The path to a file that creates a plumber2 API object. Can
be omitted in which case an API object will be created for you
freeze_opt
Logical specifying whether any options you currently have
locally (either as environment variables or R options) should be written to
the _server.yml file. Shared secret will never be written to the file and
you must find a different way to move that to your deployment server.
