BUILDING VOLTRA: RENDERER

Summary from the TLDR Dev newsletter

Voltra is a library for building native Live Activities and Widgets using standard React Native components. Voltra needed a single-pass, stateless process to convert JSX into a specific JSON structure, so it built its own custom renderer. The custom renderer functions by traversing the JSX tree, processing different node types into a platform-native JSON format, and hacking React's internal dispatcher.
