The React Native Bridge is officially dead. After years of "it's coming," the new architecture is now the only architecture. No bridge. No JSON serialization across threads. JSI handles direct C++ references instead. I've been building with react native in production for 4+ years. My honest take on what this actually changes in practice. What's genuinely better: • Native module calls that used to queue up now execute synchronously • UI thread blocking that felt "just part of RN" is mostly gone • Debugging is finally less of a guessing game What nobody tells you: • Your third-party dependencies will break things first • Audit every native module before migrating, not after • The performance gains are real, but only if your architecture was already clean. The teams that will struggle aren't the ones who don't understand JSI. They're the ones who accumulated 3 years of legacy native modules and never documented them. Clean architecture isn't just about folders. It's about not being held hostage by your own codebase when the ecosystem moves. Migrating to the new architecture in 2026, where are you in the process?
