This talk takes a deeper look at how React Native moves into an existing native application without forcing a big-bang rewrite.

It covers phased adoption, the architectural boundary between native and React Native, and the tooling required to make a hybrid application maintainable. It also examines the difficult parts that appear in production, including navigation ownership, state and data exchange, multiple entry points, packaging, and performance optimization.
