@base-ui-components/react/esm/portal/PortalContext.js

Base UI is a library of headless ('unstyled') React components and low-level hooks. You gain complete control over your app's CSS and accessibility features.

import * as React from 'react';
export const PortalContext = /*#__PURE__*/React.createContext(undefined);
if (process.env.NODE_ENV !== 'production') {
  PortalContext.displayName = 'PortalContext';
}
export function usePortalContext() {
  const context = React.useContext(PortalContext);
  if (context === undefined) {
    throw new Error('Base UI: PortalContext is missing. Portal parts must be placed within the Root of a component.');
  }
  return context;
}
