renderToStaticMarkup

renderToStaticMarkup renders a non-interactive React tree to an HTML string.

const html = renderToStaticMarkup(reactNode, options?)

Reference ​

renderToStaticMarkup(reactNode, options?) ​

On the server, call renderToStaticMarkup to render your app to HTML.

import { renderToStaticMarkup } from 'react-dom/server';

const html = renderToStaticMarkup(<Page />);

It will produce non-interactive HTML output of your React components.

See more examples below.

Parameters ​

  • reactNode: A React node you want to render to HTML. For example, a JSX node like <Page />.
  • optional options: An object for server render.
    • optional identifierPrefix: A string prefix React uses for IDs generated by useId. Useful to avoid conflicts when using multiple roots on the same page.

Returns ​

An HTML string.

Caveats ​

  • renderToStaticMarkup output cannot be hydrated.

  • renderToStaticMarkup has limited Suspense support. If a component suspends, renderToStaticMarkup immediately sends its fallback as HTML.

  • renderToStaticMarkup works in the browser, but using it in the client code is not recommended. If you need to render a component to HTML in the browser, get the HTML by rendering it into a DOM node.

Usage ​

Rendering a non-interactive React tree as HTML to a string ​

Call renderToStaticMarkup to render your app to an HTML string which you can send with your server response:

import { renderToStaticMarkup } from 'react-dom/server';

// The route handler syntax depends on your backend framework
app.use('/', (request, response) => {
  const html = renderToStaticMarkup(<Page />);
  response.send(html);
});

This will produce the initial non-interactive HTML output of your React components.

This method renders non-interactive HTML that cannot be hydrated. This is useful if you want to use React as a simple static page generator, or if you're rendering completely static content like emails.

Interactive apps should use renderToString on the server and hydrateRoot on the client.
