Configure Rhino with rhino.yml

Rhino uses its own rhino.yml config file where you can set a few options on how it works in your app. Currently available options are described below.

rhino.yml options

sass: string               # required | one of: "node", "r"
legacy_entrypoint: string  # optional | one of: "app_dir", "source", "box_top_level"


Configures whether Sass should be built using the R package or the Node.js package. Read more in Explanation: Node.js - JavaScript and Sass tools.


This setting is useful when migrating an existing Shiny application to Rhino. For more details see rhino::app() details section.
