This repo contains 2 node HTTP server files that show how React SSR + hydration works without any framework or bundler. Therefore no JSX is used and React scripts are loaded from unpkg.
Hydrating a div
server-hydrate-div.mjs shows an example where only a <div id="app"> is hydrated and the node server manages the rendering of <html>/<head>/<body>/<script>/etc tags.
npm ci
node server-hydrate-div.mjsHydrating the full document
server-hydrate-doc.mjs shows an example where the entire <html> document is hydrated (this is a common approach for Meta Frameworks such as Remix or Next.js).
