NAME ^

Web::ChromeLogger - ChromeLogger for Perl

SYNOPSIS ^

    use Web::ChromeLogger;

    get '/', sub {
        my $logger = Web::ChromeLogger->new();
        $logger->info('hey!');
        $logger->infof('Hello, %s!', 'John');

        my $html = render_html();

        return [
            200,

    };

DESCRIPTION ^

Web::ChromeLogger is a ChromeLogger library for Perl5.

Chrome Logger is a Google Chrome extension for debugging server side applications in the Chrome console.

HOW IT WORKS ^

This module generates the string for ChromeLogger. You can send the string in 'X-ChromeLogger-Data' header in HTTP response.

For more details, please see ChromeLogger's Technical Specification

LARGE RESPONSE HEADER ^

NGINX PROXY

If you are using nginx as reverse proxy, you may need to set following parameters in your configuration file:

    proxy_buffer_size   128k;
    proxy_buffers   4 256k;
    proxy_busy_buffers_size   256k;

Maximum Data Size

Chrome has a limit of 250kb across all headers for a single request so that is the maximum amount of encoded data you can send.
