IonicNotification is an interface for Rails to use Ionic.io's Push Notification service.

Keep in mind that Ionic.io's Push Notification is still in alpha at the moment, so this gem will probably undergo some major updates in the near future.

Getting started

gem install ionic_notification

You can add IonicNotification to your Gemfile with:

gem 'ionic_notification'

After you installed IonicNotification, you need to run the generator:

rails g ionic_notification:install

Configure the ionic_notification.rb file within config/initializers. You can use the default set environment variables, change them or hardcode those values (altough is highly NOT recommended)

  IonicNotification.setup do |config|
    config.ionic_application_id = ENV["IONIC_APPLICATION_ID"]
    config.ionic_application_api_token = ENV["IONIC_APPLICATION_API_TOKEN"]
  end

Model setup

You can use IonicNotification directly from models. Run the proper generator:

rails g ionic_notification:model YOUR_MODEL

This creates a migration that will add a :device_tokens column to your model

class AddDeviceTokensTo_YOUR_MODEL < ActiveRecord::Migration
  def self.up
    add_column :your_model_table_name, :device_tokens, :text
  end

  def down
    remove_column :your_model_table_name, :device_tokens
  end
end

and includes IonicNotification in your model

# app/models/your_model.rb
class YourModel < ActiveRecord::Base
  # Include IonicNotification behaviour
  include IonicNotification::Concerns::IonicNotificable

  # Your stuff...
end

Sending a Push Notification

# Assuming you want to send a notification to a User (yeah, weird, right?)
user = User.first
user.notify message: "Your super awesome notification message!"

This will simply send a notification with the provided message to all device tokens found on user.

You can also schedule notifications to be sent later, specifying either a DateTime or a delay.

user = User.first
user.notify_at Date.tomorrow, message: "I'm a scheduled notification"
user.notify_in 2.hours, message: "I'm a delayed one instead"

If you have to send the same notification to a collection of, say, users, you have :notify_allavailable for use.

User.where(something: true).notify_all message: "Spread the word!"

If you want to learn more about all the parameters a notification accepts, please refer to the notification parameters section.

Check notification status

IonicNotification stores your last sent notifications (3 by default), so that you check their status later. You access them by calling

IonicNotification.latest_notifications

which returns an array of IonicNotification::SentNotifications, a representation of the notifications you built before.

On each of those you can call the :status method, and it will fetch the notification status from Ionic API.

# If you want to know what happened to your lost notification,
# or if you're simply curious about its status
notification = IonicNotification.latest_notifications.first
notification.status

Notification parameters

• :tokens: The device tokens, the targets for your notifications. It accepts an Array or a String.
• message: The awesome message you want to display through your notification.
• schedule: Pass a DateTime to schedule your notification. You can use :notify_at and :notify_in methods to do this.
• payload: You can pass a Hash here to define a common payload for both iOS and Android.
• ios_payload: You can pass a Hash to specify a payload for iOS devices.
• android_payload: You can pass a Hash to specify a payload for Android devices.
• production: You can override IonicNotification.ionic_app_in_production for each of your notifications. Take a look at the configuration section for further details.
• :title: See the ionic_app_name in the configuration section for further details.

Manually send a notification

In some cases, you may want to manually instantiate and send notifications. You can:

notification = IonicNotification::Notification.new(
  tokens: ["array", "of", "tokens"],
  message: "Your message"
) # You can pass any of the parameters of course.
notification.send

Configuration

Here you'll find all required and optional options

ionic_application_id

required

This is, wait for it, your Ionic application id, should be something like "258d401f"

ionic_application_api_token

required

This must equal your Ionic API key, should be a pretty long string.

development_profile_tag

Your Ionic development security profile tag

production_profile_tag

Your Ionic production security profile tag

ionic_app_name

ionic_app_name will be used as the default title for your notifications, though in most cases on devices you will see the name of the installed app. It defaults to Rails.application.class.parent_name.

ionic_app_in_production

If ionic_app_in_production is set to true, notifications will be sent to all devices which have your Ionic app running with production certificates (a.k.a apps generally coming from store). Otherwise, if set to false, they'll be sent to all devices which have your app running with developer certificates. While it is set to true by default, if you want a more flexible solution set it to Rails.env.production?, so that notifications will be sent to "production devices" only while Rails app is running in production environment.

log_level

Defaults to :debug, customize it according to your needs. Available log levels are Rails standards: :debug, :info, :warning, :fatal, :unknown.

notification_store_limit

IonicNotification stores your last 3 sent notifications, unless you specify otherwise. As they're kept in memory, I seriously advise not to go nuts on this parameter setting it trillions of trillions.

process_empty_messages

By default, notifications with no message provided will be skipped, you don't want your clients to receive a notification with no message, right? Well, sometimes it can be useful to speed up development and tests. You could like to be able to do something like this, from time to time:

User.first.notify

and see what happens, without bothering writing a fake message. You can enable this, if you want, setting process_empty_messages to true, or do it in a more safe way: !Rails.env.production?.

default_message

If you're allowing IonicNotification to process empty messages (see above), you'll want to set a default message.

ionic_api_url

Refer to Ionic documentation for further information. It defaults to the standard Ionic endpoints.
