Autodetect the app type from a directory

Scans appdir for Shiny entrypoints and returns the implied language. R apps may use app.R or the pair server.R plus ui.R. Python apps use app.py. A directory that carries both R and Python entrypoints is rejected; the multi-app-suite path is the right place to combine them.

Usage

detect_app_type(appdir)

Arguments

appdir

Character path to the candidate app directory. Must exist.

Value

Character, either "r-shiny" or "py-shiny".
