Migrating a Large App to the New React Native Architecture

The New React Native Architecture which combines Fabric with TurboModules and JSI will deliver improved application startup times and better animation performance and enhanced reliability of the connection between native code and JavaScript code. The process of migrating a complete production application requires more effort than simply using a switch to complete the task. In this post, I will present a complete guide which includes: The actual architectural differences which exist in the new system The complete process for migrating large applications The most frequent mistakes Code examples (JS + Native) The effects of this situation on react native app development services and the total development expenses for react native applications Why the New Architecture Matters The legacy React Native bridge used asynchronous JSON serialization for its data processing which resulted in the following problems: Frame drops Expensive re-renders Complex native module code The new architecture in
