jsx_rosetta is a JSX-to-Rails translator. It parses JSX via Babel (over a Node sidecar), lowers the parsed AST into a framework-agnostic semantic IR, and emits target output via pluggable backends. The initial backend produces ViewComponent classes paired with ERB templates; additional backends (Phlex, Slim, Phoenix LiveView, etc.) can be added against the same IR.
