Return the cache directory for the current context.
sass_cache_context_dir()
In most cases, this function returns the user's cache directory, by calling
tools::R_user_dir("sass", which = "cache")
(for R 4.0 and above) or
rappdirs::user_cache_dir("R-sass")
(for older versions of R).
If this function is called from a Shiny application, it will also look for a
subdirectory named app_cache/
. If it exists, it will use a directory named
app_cache/sass/
to store the cache.
When running a Shiny application in a typical R session, it will not create
the app_cache/
subdirectory, but it will use it if present. This scopes the
cache to the application.
With Shiny applications hosted on Shiny Server and Connect, it will create
a app_cache/sass/
subdirectory, so that the cache is scoped to the
application and will not interfere with another application's cache.
