Cipolleschi says the New Architecture was covered in an RFC published before the React Native 0.82 branch was cut in September. He describes React Conf as a chance to explain the work to a wider audience. The team began work on the architecture in 2018 and now wants the community to realize its benefits.
It's Not New Anymore: How New Architecture Unlocks React 19
Speaker
Riccardo Cipolleschi of Meta’s Core team discusses React Native’s New Architecture and its path to supporting React 19 features with a Callstack host at React Conf in Henderson, Nevada.
Cipolleschi highlights the ecosystem and React Native apps reaching the top of app stores and winning awards. He says it is fulfilling to see the work help people build products and earn a living. He points to Hermes V1 as a major next step, while noting performance and DevTools are areas he does not work on directly.
The host connects the architecture’s building blocks to DOM APIs, concurrent rendering, and React’s Activity component. Cipolleschi says React Native first needs to include React 19.2, after which the team will work toward making Activity function there. He expects much of the feature to work on the React side, though some adjustments may be needed.
Cipolleschi confirms that some topics were held back from React Universe Conf for React Conf. The host sees React Native’s prominent place at the event as evidence of its connection to the wider React community and the React Foundation.
Takeaways
- An RFC can make a major architecture change public well before a conference announcement reaches most developers.
- React Native’s New Architecture is the result of work that began in 2018.
- React 19.2 must be integrated into React Native before its Activity feature can be evaluated there.
- The expected integration path is largely on the React side, with possible adjustments still to be determined.
- Ecosystem outcomes such as successful apps and awards can show the practical impact of platform work.
