React SSR with client-side hydration in Val Town

{count}

\n \n \n \n \n );\n}\n\nexport default render(App, import.meta.url);\n```\n\n[Live example](https://www.val.town/v/jxnblk/ReactStreamDemo)\n\nTo render static HTML without hydration, pass `false` as the second argument.\n\n```tsx\nexport default render(App, false);\n```\n\n## Middleware\n\nCustom middleware can be added in an array as the third argument.\nMiddleware can add data to the `req.data` object or return a response for things like API endpoints.\n\n```tsx\nexport default render(App, import.meta.url, [\n analytics,\n robots(\"User-agent: *\\nAllow: /\"),\n getInitialProps\n])\n```\n\n### robots.txt\n\nReactStream has a built-in middleware to handle request to `/robots.txt`\n\n```tsx\nimport { render, robots } from \"https://esm.town/v/jxnblk/ReactStream\";\n// ...\nexport default render(App, import.meta.url, [\n robots(\"User-agent: *\\nAllow: /\"),\n])\n```\n\n### Add a backend request handler\n\n```tsx\n// example middleware\nasync function api (req: Request, res: Response, next): Promise {\n if (req.pathname !== \"/api\") return next();\n if (req.method === \"POST\") {\n return Repsonse.json({ message: \"Hello POST request\" });\n }\n return Response.json({ ok: true });\n}\n\nexport default render(App, import.meta.url, [ api ]);\n```\n\n### Fetch data on the server to set initial props\n\n\n```tsx \n// example middleware\nasync function getInitialProps (req: Request, res: Response, next) {\n // fetch data or do async work to pass as props to the component\n req.data = {\n hello: \"props\",\n };\n return next();\n}\n\nexport default render(App, import.meta.url, [ getInitialProps ]);\n```\n\n## Starter template\n\n```tsx\n/** @jsxImportSource https://esm.sh/react */\nimport { render } from \"https://esm.town/v/jxnblk/ReactStream\";\n\nfunction App () {\n return (\n \n \n ReactStream\n \n \n hello\n \n \n );\n}\n\nexport default render(App, import.meta.url, []);\n```\n\nReact requires matching versions for SSR and hydration.\nImport `React` from `https://esm.town/v/jxnblk/ReactStream` to ensure your component uses the same version as this library (currently react@18.3.1).\n\nInspired by https://www.val.town/v/stevekrouse/react_http & https://www.val.town/v/stevekrouse/reactClientDemo\n\n\nMigrated from folder:
