React Native is powerful, but what if you could use native CSS directly? And what if you could solve the pain of hybrid native/React Native lists?

Xuan Huang, Architect at Bytedance, introduces Lynx, a framework-agnostic platform inspired by React Native. He explains Lynx's killer features:
➡️ Native CSS support: Stop rewriting styles. Port your existing web CSS files directly, making web-to-mobile migration easier.
➡️ Two-thread architecture (BTS/MTS): A new model designed to solve the synchronization issues of mixing native UI components and React-based views, allowing interactivity on the main thread.

Xuan also discusses the future of React as a specification, how the community is already building support for Vue and Svelte on Lynx, and how Lynx powers the mini app ecosystem at Bytedance.
