Question 1

How do I set up Rpush with Ruby on Rails?

Accepted Answer

After adding the gem to your Gemfile, run `bundle exec rpush init`; Rpush automatically detects Rails environments and integrates seamlessly, with configuration stored in `config/rpush.rb` for easy management.

Question 2

Rpush vs OneSignal: which is better for my app?

Accepted Answer

Rpush is a self-hosted Ruby gem offering full control and no vendor lock-in, ideal for Ruby teams needing customization. OneSignal is a managed SaaS with built-in analytics and easier setup, better for projects wanting minimal maintenance.

Question 3

How to handle APNs certificate expiration in Rpush?

Accepted Answer

Use the `ssl_certificate_will_expire` reflection hook from the Reflection API to set up alerts. Rpush allows monitoring expiration dates, so you can update certificates before they expire to avoid service disruption.

Question 4

Can Rpush send notifications to iOS and Android simultaneously?

Accepted Answer

Yes, Rpush supports concurrent notifications to multiple platforms. Create separate app configurations (e.g., `Rpush::Apnsp8` for iOS, `Rpush::Fcm` for Android) and send notifications using their respective classes in your code.

Question 5

What's the best way to scale Rpush for high volume?

Accepted Answer

Scale vertically by increasing the `connections` parameter per app, or horizontally by running multiple Rpush processes. Use Redis for storage to handle high throughput, and deploy in daemon mode with process monitoring for reliability.

Question 6

How to monitor errors and delivery failures in Rpush?

Accepted Answer

Leverage the Reflection API for hooks on errors, and integrate with plugins like Sentry or StatsD. Rpush provides fine-grained instrumentation to log failures, handle retries, and track performance metrics effectively.

Question 7

Is Rpush suitable for web push notifications in browsers?

Accepted Answer

Yes, Rpush supports Webpush via the VAPID protocol for modern browsers. You need to generate key pairs, store them in the app configuration, and handle browser subscriptions, as detailed in the Webpush section of the README.
