The push notification service for Ruby.

Rpush. The push notification service for Ruby.

Rpush aims to be the de facto gem for sending push notifications in Ruby. Its core goals are ease of use, reliability and a rich feature set. Rpush provides numerous advanced features not found in others gems, giving you greater control & insight as your project grows. These are a few of the reasons why companies worldwide rely on Rpush to deliver their notifications.

Supported Services

• Apple Push Notification Service
  • Including Safari Push Notifications.
• Google Cloud Messaging
• Amazon Device Messaging
• Windows Phone Push Notification Service

Feature Highlights

• Use ActiveRecord, Redis or MongoDB for storage.
• Plugins for Bugsnag, Sentry, StatsD or write your own.
• Seamless integration with your projects, including Rails.
• Run as a daemon, inside a job queue, on the command-line or embedded in another process.
• Scales vertically (threading) and horizontally (multiple processes).
• Designed for uptime - new apps are loaded automatically, signal HUP to update running apps.
• Hooks for fine-grained instrumentation and error handling (Reflection API).
• Works with MRI, JRuby and Rubinius.

Getting Started

Add it to your Gemfile:

gem 'rpush'

Initialize Rpush into your project. Rails will be detected automatically.

$ cd /path/to/project
$ rpush init

Create an App & Notification

Apple Push Notification Service

If this is your first time using the APNs, you will need to generate SSL certificates. See Generating Certificates for instructions.

app = Rpush::Apns::App.new
app.name = "ios_app"
app.certificate = File.read("/path/to/sandbox.pem")
app.environment = "sandbox" # APNs environment.
app.password = "certificate password"
app.connections = 1
app.save!

n = Rpush::Apns::Notification.new
n.app = Rpush::Apns::App.find_by_name("ios_app")
n.device_token = "..." # 64-character hex string
n.alert = "hi mom!"
n.data = { foo: :bar }
n.save!

The url_args attribute is available for Safari Push Notifications.

You should also implement the ssl_certificate_will_expire reflection to monitor when your certificate is due to expire.

Google Cloud Messaging

app = Rpush::Gcm::App.new
app.name = "android_app"
app.auth_key = "..."
app.connections = 1
app.save!

n = Rpush::Gcm::Notification.new
n.app = Rpush::Gcm::App.find_by_name("android_app")
n.registration_ids = ["..."]
n.data = { message: "hi mom!" }
n.save!

GCM also requires you to respond to Canonical IDs.

Amazon Device Messaging

app = Rpush::Adm::App.new
app.name = "kindle_app"
app.client_id = "..."
app.client_secret = "..."
app.connections = 1
app.save!

n = Rpush::Adm::Notification.new
n.app = Rpush::Adm::App.find_by_name("kindle_app")
n.registration_ids = ["..."]
n.data = { message: "hi mom!"}
n.collapse_key = "Optional consolidationKey"
n.save!

Windows Phone Notification Service

app = Rpush::Wpns::App.new
app.name = "windows_phone_app"
app.client_id = # Get this from your apps dashboard https://dev.windows.com
app.client_secret = # Get this from your apps dashboard https://dev.windows.com
app.connections = 1
app.save!

n = Rpush::Wpns::Notification.new
n.app = Rpush::Wpns::App.find_by_name("windows_phone_app")
n.uri = "http://..."
n.data = {title:"MyApp", body:"Hello world", param:"user_param1"}
n.save!

Running Rpush

It is recommended to run Rpush as a separate process in most cases, though embedding and manual modes are provided for low-workload environments.

See rpush help for all available commands and options.

As a daemon

$ cd /path/to/project
$ rpush start

On the command-line

$ rpush push

Rpush will deliver all pending notifications and then exit.

In a scheduled job

Rpush.push
Rpush.apns_feedback

See Push API for more details.

Embedded inside an existing process

if defined?(Rails)
  ActiveSupport.on_load(:after_initialize) do
    Rpush.embed
  end
else
  Rpush.embed
end

Call this during startup of your application, for example, by adding it to the end of config/rpush.rb. See Embedding API for more details.

Using mina

If you're using mina, there is a gem called mina-rpush which helps you control rpush.

Configuration

See Configuration for a list of options.

Updating Rpush

You should run rpush init after upgrading Rpush to check for configuration and migration changes.

Contributing

When running specs, please note that the ActiveRecord adapter can be changed by setting the ADAPTER environment variable. For example: ADAPTER=postgresql rake.

Available adapters for testing are postgresql, jdbcpostgresql, mysql2, jdbcmysql, jdbch2, and sqlite3.

Note that the database username is changed at runtime to be the currently logged in user's name. So if you're testing with mysql and you're using a user named 'bob', you will need to grant a mysql user 'bob' access to the 'rpush_test' mysql database.

To switch between ActiveRecord and Redis, set the CLIENT environment variable to either active_record, redis or mongoid.
