# Opal-Pusher

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

## Installation

Add this line to your application's Gemfile:

```ruby

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:

```ruby

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:

```ruby

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:

```ruby

foo_channel.bind 'update' do |data|

  FooRepository[data[:id]].set_attributes data

  App.render # Rerender the app with new data

end

```
