A single JSON interface definition for each component automatically generates four platform-specific libraries (Python for backend, Kotlin for Android, Swift for iOS, TypeScript/React for Web), ensuring consistent serialization and deserialization across all clients. The post covers how tokens (colors, icons, etc.) are handled, and how a versioning and migration system ensures backward compatibility when component interfaces change — allowing older app versions to continue working as components evolve. ## Full article daily.dev links to this article rather than hosting it.
