The push notification service for Ruby. Without GPL components.

Rpush. The push notification service for Ruby.

• Supported services:

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

• Supported storage backends:

  • ActiveRecord
  • Redis

• Optional Rails integration (version 3 & 4).

• Scales vertically (threading) and horizontally (multiple processes).

• Designed for uptime - new apps are loaded automatically, signal HUP to update running apps.

• Run as a daemon or inside an existing process.

• Use in a scheduler for low-workload deployments (Push API).

• 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 = "..."
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 = ["token", "..."]
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!

For more documentation on ADM.

Windows Phone Notification Service

app = Rpush::Wpns::App.new
app.name = "windows_phone_app"
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.

As a daemon (recommended):

cd /path/to/project
rpush start

See rpush help for all available commands and options.

One-off, manual

On the command-line:

rpush push

In your code:

Rpush.push
Rpush.apns_feedback

See Push API for more details.

Embedded inside an existing process

# Call this during startup of your application, for example, by adding it to the end of config/rpush.rb
Rpush.embed

See Embedding API for more details.

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.

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 mysql, mysql2 and postgresql.

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 or :redis.
