setCrunchyAuthorization: Register authorization logic for your Crunchy app
Description
Call this to set an expression or server function to evaluate to determine
whether the current user is authorized to access your app. Ideally, this is
cheap to execute because it will be called repeatedly.
Usage
setCrunchyAuthorization(func)
Arguments
func
A function (input, output, session) to call
inside crunchyServer()
Value
Invisibly, the server function. This function is called
for the side effect of setting the authorization function globally. The
function should return TRUE if the current user is authorized.
# NOT RUN {setCrunchyAuthorization(function (input, output, session) {
# Restrict to users who have crunch.io emails endsWith(email(shinyUser()()), "@crunch.io")
})
# }
