Case
- Goal
- Differentiate React 19 Node vs Web stream entrypoints in react-dom/server and react-dom/static, async component suspension crashes in renderToString, and react-server condition entrypoint restrictions HOW
- Packages
- react-dom 19.0.0
- Environment
- node
- Created
- 2026-08-16T07:54:05Z
Contract
- react-dom/server resolves to server.node.js in Node, exposing renderToPipeableStream while renderToReadableStream is undefined
- react-dom/static resolves to static.node.js in Node, exposing prerenderToNodeStream while Web prerender is undefined
- ReactDOMServer.renderToString throws synchronously when invoked on async components in React 19
- ReactDOMStatic.prerenderToNodeStream successfully streams and renders async components in Node
- Running Node with --conditions=react-server throws on importing react-dom/server, react-dom/client, or react-dom/static
- Running Node with --conditions=react-server restricts root react-dom to resource preload hints while omitting DOM mutation APIs
