NAME

Plack::Middleware::LogErrors - Map psgi.errors to psgix.logger or other logger

VERSION

version 0.003

SYNOPSIS

Using a logger you have already configured (using Log::Dispatch as an example):

    use Log::Dispatch;
    my $logger = Log::Dispatch->new;
    $logger->add( Log::Dispatch::File->new(...) );

    builder {
        enable 'LogDispatch', logger => $logger;
        enable 'LogErrors';
        $app;
    }

Using an explicitly defined logger:

    builder {
        enable 'LogErrors', logger => sub {
            my $args = shift;
            $logger->log(%$args);
        };
        $app;
    }

DESCRIPTION

psgi.errors defaults to STDERR in most backends, which results in content going somewhere unhelpful like the server console.

This middleware simply remaps the psgi.errors stream to the psgix.logger stream, or an explicit logger that you provide.

This is especially handy when used in combination with other middlewares such as Plack::Middleware::LogWarn (which diverts Perl warnings to psgi.errors); Plack::Middleware::HTTPExceptions (which diverts uncaught exceptions to psgi.errors); and Plack::Middleware::AccessLog, which defaults to psgi.errors when not passed a logger -- which is also automatically applied via plackup (so if you provided no --access-log option indicating a filename, psgi.errors is used).

CONFIGURATION

logger

A code reference for logging messages, that conforms to the psgix.logger specification. If not provided, psgix.logger is used, or the application will generate an error at runtime if there is no such logger configured.
