Rapscallion is an asynchronous React VirtualDOM renderer for server-side rendering. It offers streaming output, templating for HTML boilerplate, and component caching, and is roughly 30% faster than React's renderToString.
Use cases
- render react components to html on the server asynchronously
- stream server-rendered html to the client as it renders
- speed up react ssr compared to renderToString
- wrap server-rendered react html in a page template while streaming
- cache rendered react component html for faster ssr
When to choose
- you need non-blocking, streaming SSR for a React app on Node.js
- renderToString is too slow or blocks your server event loop
- you want template-based HTML wrapping integrated with streaming SSR
When to avoid
- you use modern React 18+, which has built-in streaming SSR via renderToPipeableStream
- your project is not React-based
- you need a library with active development and recent updates
