questions

Does this handle multi-document YAML?

Yes. If your YAML contains --- separators, each document is parsed separately and returned as a JSON array. Single documents return a JSON object.

How does YAML type coercion work?

YAML converts "true", "false", "yes", "no" to booleans and "null" to null. If you need these as strings, wrap them in quotes in your YAML input.
