So, You Want to Port To Rails

  • Desired talk duration: 30 or 45 minutes

Abstract

You have a legacy app that you wish was running on Rails. Get some insight from a port of a seven year old application written in Java and Groovy using Struts 2, JPA and a bunch of other Java frameworks. Learn the strategies we used to successfully port core business logic while maintaining correctness. How we leveraged JRuby to enable an incremental approach. How we ported tests while maintaining the same semantics. How we automated translation of code from Java and Groovy to Ruby. How we were able to make the system more easily modular and break it into services. Where we tripped up, and caused ourselves problems. Learn from our mistakes so you don't have to repeat them. And finally why would you EVER do this?

Notes

I have never given this talk before. This talk is definitely a war story, with a good outcome. This port is still in progress. The strategies we used have allowed us to do an incremental port of the application that has dramatically lowered the overall risk.
