rsx-rb

https://github.com/derwydd/rsx

RSX is a template language that brings React's JSX authoring model to Ruby. Write .rsx files where Ruby replaces JavaScript and markup is embedded directly in expression position, including fragments (<>), expression containers ({}), spread attributes and composable components. Templates compile ahead of time to plain Ruby string building, so rendering is fast and cacheable. Zero runtime dependencies; Rails integration is optional and loads automatically when present.
