Rapid App Development With React Native: Lessons Learned at NSB
summary
NSB moves a huge legacy app (over 1M tickets sold yearly, ~2M downloads) to a new backend and a React Native front end, building a cloud ticketing service that splits orders into single tickets, simplifies queries, and enables device transfer rules. Team uses React Native with ~40–45% shared code, hot reloading for fast iteration, staged Android rollouts (1→5→30%) and backend traffic ramping to 1% before full launch. It ships by Dec 22 with monitoring and a minor postlaunch bug that forces hundreds to contact support.
