This response middleware provides basic logging of requests to a file handle. By default, it logs both successful requests (response code less than 400) and errors (response code at least 400) to
$*OUT (the standard out file handle), which is likely suitable for container deployment and development. To avoid any buffering issues delaying logs, it also defaults to flushing after each output.
Using Alternate File Handles§
To log all requests (both success and error) to another location, pass the
my $logger = Cro::HTTP::Log::File.new(logs => open('http.log', :a));
To log errors to a different file, also pass the
my $logger = Cro::HTTP::Log::File.new: logs => open('http.log', :a), errors => open('error.log', :a);
To disable flushing of logs after each write, set the
flush option to
my $logger = Cro::HTTP::Log::File.new: logs => open('http.log', :a), flush => False;
If you need something more complex§
If you want logs in a different format or sent elsewhere, check in the Raku module ecosystem to see if somebody already wrote such a module or, failing that, implement it by writing a custom response middleware and using it in place of Cro::HTTP::Log::File.
