LaunchDarkly SSE Client for Ruby

A client for the Server-Sent Events protocol. This implementation runs on a worker thread, and uses the http gem to manage a persistent connection. Its primary purpose is to support the LaunchDarkly SDK for Ruby, but it can be used independently.

Parts of this code are based on https://github.com/Tonkpils/celluloid-eventsource, but it does not use Celluloid.

Supported Ruby versions

This gem has a minimum Ruby version of 3.1.

Quick setup

1. Install the Ruby SDK with gem:

gem install ld-eventsource

2. Import the code:

require'ld-eventsource'

3. Create a new SSE client instance and register your event handler:

sse_client=SSE::Client.new("http://hostname/resource/path")do |client|
client.on_eventdo |event|
puts"I received an event: #{event.type}, #{event.data}"endend

For other options available with the Client constructor, see the API documentation.
