RailsConf 2025 The Future of: PWAs on Rails by Edy Silva

### Pitch Rails is one of the best frameworks for building web applications. It's simple, yet powerful. Core Rails is always adding new features that increase productivity and make the developer's life easier. Since version 7.2, Rails has added PWA components to the default setup. DHH himself said that he will be pushing hard for PWAs: "No native apps, just the very best PWAs you can build." There are lots of HTML APIs that can make your app behave like a native app. Device-native features like Geocoding, Device Motion, Battery status, and more can be accessed through the browser. PWA implementations are evolving. The new `ActionNotifier` gem is on its way to make it easier to send push notifications. But PWAs have a lot more to offer and you can start using them today in a Rails way so you can be ready for when Rails is indeed, full PWA-ready. ### Outcomes After attending this talk, the audience should know: 1. Know the most important PWA patterns: Cache and caching strategies, Push Notifications, and Offline Capabilities. 2. How to leverage Rails to implement these patterns today (e.g. Rails generators). 3. What to expect from Rails in the future regarding PWAs. ### Outline #### Intro - What PWAs can do today - Why PWAs? - PWA patterns - Cache and caching strategies - Push Notifications - Offline Capabilities #### Fit PWAs in Rails way - The Rails way - Rails generators for PWAs #### Where do we go from here? - What to expect from ActionNotifier - What to expect from Rails regarding PWAs
