feetures for feature flags

Installation

devtools::install_github("ropenscilabs/feetures")

library("feetures")

basic usage

initialize object

(z <- Feetures$new(adapter = AdapterMemory$new()))

register a flag

z$register("foo")

if/else conditional

if (z$enabled("foo")) {
  message("foo for you :)")
} else {
  message("NO foo for you!")
}

enable the flag

z$enable("foo")

now try again

if (z$enabled("foo")) {
  message("foo for you :)")
} else {
  message("NO foo for you!")
}

expiration

feat <- Feature$new("bar", expiration = Sys.time() + 5)
(z <- Feetures$new(adapter = AdapterMemory$new()))
z$register(feat)
z$features()
z$enable(feat$name)
z$enabled(feat$name)
Sys.sleep(5)
z$enabled(feat$name)

TODO

• ability to ignore all feature flags? i.e., set to FALSE?
• possibly a helper to pass code into a method like:

feat_if_else(feature = "foo", code = {
  x <- 5^2
  x / 10 
})
