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.

METHODS

my $logger = Web::ChromeLogger->new(%args)

Create new instance with following parameters:

json_encoder (Default: JSON::XS->new()->ascii(1)->convert_blessed )
