NAME

Lumberjack::Dispatcher::EventSource - dispatch Lumberjack messages to server sent events

SYNOPSIS

use Lumberjack;
use Lumberjack::Dispatcher::EventSource;
use Cro::HTTP::Router;
use Cro::HTTP::Server;

my $dispatcher = Lumberjack::Dispatcher::EventSource.new

Lumberjack.dispatchers.append: $dispatcher;


my $app = route {
    get -> {
        content 'text/event-stream', $dispatcher.Supply;
    }
};

my Cro::Service $log = Cro::HTTP::Server.new(:host<localhost>, :port<7798>, application => $app);

$log.start;

react whenever signal(SIGINT) { $log.stop; exit; }

DESCRIPTION

This is a Lumberjack::Dispatcher implementation that emits the log messages as JSON (as formatted by Lumberjack::Message::JSON,) on a supply in the format of Server Sent Events. The Supply can be passed as a response to a web toolkit that supports chunked encoding such as Cro or Crust.

This may be useful if you want to expose your logging to the web or to some log archover or something.

The exact format of the JSON emitted is documented by Lumberjack::Message::JSON

METHODS

method new

method new()

This takes the classes and levels parameters that are provided for by Lumberjack::Dispatcher and constraint the messages that are handled but has no other useful parameters.

attribute Supply

This is the Supply to which the messages will be emitted. In some places this will be used as a coercion so the object itself can be passed.
