It's now 2018. Most hype and notable examples I saw with RN were around 2016 (https://facebook.github.io/react-native/showcase.html).<p>What is the state of React Native today? How are you using it successfully, and at what scale? Any large applications that have fully implemented it?<p>My success isn't beyond fast proofs-of-concepts or simple ux applications. Success for me is defined as a system engineered simply and effectively.<p>So my naive assumption is that it cannot reach much "success" beyond the hype it generates in the JS community. I work on production native iPad apps with iOS, and can not imagine that their development in RN would be "simple" like it is natively. Cross-platform is great & I can develop fast with RN-- But, I always feel like something is off, and that I'm engineering around leaky-abstractions and that "custom tweaks/hacks" occur more often than not (which rarely occur when working with native SDKs).
I'm coming to the end of a build of an RN app for a startup with lots of custom mapping and graphing stuff. It leans heavily on MapboxGL and react-native-svg to do some cool stuff. Building the same thing natively would have taken at least 3* longer, and there haven't been any particularly bad hacks necessary. I've been impressed by the performance too. I have no regrets about using RN.
