robots.txt\n\nReactStatic has a built-in middleware to handle request to `/robots.txt`\n\n```tsx\nimport { render, robots } from \"https://esm.town/v/jxnblk/ReactStatic\";\n// ...\nexport default render(App, [\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, [ 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, [ getInitialProps ]);\n```\n\n## Starter template\n\n```tsx\n/** @jsxImportSource https://esm.sh/react@18.3.1 */\nimport { render } from \"https://esm.town/v/jxnblk/ReactStatic\";\n\nfunction App () {\n return (\n \n \n ReactStatic\n \n \n hello\n \n \n );\n}\n\nexport default render(App, []);\n```\n\nReact requires matching versions for SSR and hydration -- ensure you import `react@18.3.1` when using this library.\n\nInspired by
