To check whether a given variable holds an empty string, either compare it to the empty string literal or check its length.
<lang elixir>
empty_string = ""
not_empty_string = "a"
empty_string == ""
# => true
String.length(empty_string) == 0
# => true
not_empty_string == ""
# => false
String.length(not_empty_string) == 0
# => false
</lang>
