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 ToastViewportContext = /*#__PURE__*/React.createContext(undefined);
if (process.env.NODE_ENV !== "production") ToastViewportContext.displayName = "ToastViewportContext";
export function useToastViewportContext() {
  const context = React.useContext(ToastViewportContext);
  if (!context) {
    throw new Error('Base UI: ToastViewportContext is missing. Toast parts must be placed within <Toast.Viewport>.');
  }
  return context;
}
