yarn add @leafygreen-ui/emotion

npm install @leafygreen-ui/emotion

Because we use a custom instance of Emotion to allow for styles defined in LeafyGreen to be easily overwritten, there's an additional step that must be taken to use our components when performing server-side rendering.

We expose three methods as named exports that are also exposed by the base emotion-server package: renderStylesToString, renderStylesToNodeStream, and extractCritical. You can find documentation on usage of each of the methods in the official Emotion documentation.

NOTE: If you are already server-side rendering an application using Emotion, you will use the methods exposed in @leafygreenui/emotion instead of, NOT in addition to the methods exposed by emotion-server.

import { renderToString } from 'react-dom/server';
import { renderStylesToString } from '@leafygreen-ui/emotion';
import App from './App';

const html = renderStylesToString(renderToString(<App />));
