It looks like servr might be what you're looking for these days.

https://cran.rstudio.com/web/packages/servr/index.html

Example code

writeLines("
Hi
", "index.html")

# install.packages("servr")
library(servr)
servr::httd()

# createTcpServer: address already in use
# To stop the server, run servr::daemon_stop(2) or restart your R session
# Serving the directory /Users/st/R/localhost at http://127.0.0.1:7826

Place the address in the browser: http://127.0.0.1:7826
