Action status

Development monorepo for "React Strict DOM".

React Strict DOM (RSD) is an experimental integration of React DOM and StyleX that aims to improve and standardize the development of styled React components for web and native. The goal of RSD is to improve the speed and efficiency of React development without compromising on performance, reliability, or quality. Building with RSD is helping teams at Meta ship features faster, to more platforms, with fewer engineers.

To support native platforms, RSD builds on the design goals of the "React DOM for Native proposal" by polyfilling a large number of standard APIs, and by leveraging new web capabilities coming to React Native such as DOM traversal and layout APIs and a well-defined event loop processing model.

React Native compatibility is a work in progress. Please see for a detailed breakdown and links to specific issues; register your interest (e.g., thumbsup reaction) in supporting missing features on native platforms.
