Opal-Pusher

Opal-Pusher is a set of Ruby bindings for the Pusher API.

Installation

Add this line to your application's Gemfile:

gem 'opal-pusher'

And then execute:

$ bundle

Or install it yourself as:

$ gem install opal-pusher

Usage

You'll need to pass your Pusher API key into your front-end app somehow. In Rails apps, I usually use the gon gem for this:

gon.push pusher_api_key: ENV.fetch('PUSHER_API_KEY')

Once you have that accessible from the front-end, you can open up a Pusher connection in your Opal app like this:

require 'pusher' # Load this library

pusher = Pusher.new(`gon.pusher_api_key`)
channel = pusher.subscribe("my-pusher-channel")
channel.bind "my-pusher-event" do |data|
  puts data # data is a hash
end

I've been using this to set the attributes of models in Clearwater apps:

foo_channel.bind 'update' do |data|
  FooRepository[data[:id]].set_attributes data
  App.render # Rerender the app with new data
end
