As single page apps become common, more and more logic becomes duplicated between the front and back-end and we spend more time writing ugly API glue code. Volt lets developers write their app code in ruby and have it run both in the browser and on the server, thus removing the boilerplate of web development and produce reactive apps at minimal cost. In this short presentation, Heri presents why Volt was created and does a live demo at the montrealrb meetup Tuesday Sep 15th Read more: https://github.com/heri/montrealrb-chat https://medium.com/product-dot-io/developer-happiness-with-volt-framework-150accdf6897 http://voltframework.com

7. RUBY ON RAILS
• Rails in 2015 requires a lot of peripheral
knowledge to understand and develop a full app
• What to do on the front-end? Welcome to the
sea of complexity!

8. VOLT FRAMEWORK
• MVVM ruby framework :
• isomorphic. Same Ruby code runs on the server and client (Opal)
• reactive bindings
• components (building blocks of your app)
• nice handling of async: Promises
• I can develop single page apps in record time!
