A Raku client for Server-Sent Events

Build Status


use EventSource::Client;

react {
    whenever EventSource::Client.new(source => "") -> $event {
        say "> " ~ $event.data;


Server-Sent Events provide a mechanism for timely delivery of server to client events over HTTP and can in some use-cases be more convenient than a similar pattern implemented using Web Sockets and is easier on the network than, for instance, HTTP polling by the client.

This library allows you to consume server sent events in a Raku program in a reasonably idiomatic and reactive fashion.


Assuming you have a working Rakudo installation then you should be able to install this with zef :

zef install EventSource::Client

# Or from a local clone

zef install .
