Macro Summary
Instance Method Detail
Processes the path based on exclude
paths which is a Array(String)
.
If the path is not found on exclude
conditions the handler will continue processing.
If the path is found in exclude
conditions it'll stop processing and will pass the request
to next handler.
However this is not done automatically. All handlers must inherit from Kemal::Handler
.
class ExcludeHandler < Kemal::Handler
exclude ["/"]
def call(env)
return call_next(env) if exclude_match?(env)
puts "If the path is not / i will be doing some processing here."
end
end
