@base-ui/react/utils/NullStore.mjs

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 { ReactStore } from '@base-ui/utils/store';
/**
 * A `ReactStore` whose state never changes.
 *
 * Useful for fallback stores that need to support normal store reads while detached from the
 * component that owns real state. Context values may still contain mutable refs or maps.
 */
export class NullStore extends ReactStore {
  // `update`/`set`/`notifyAll` funnel through `setState` in the base `Store`, so overriding
  // `setState` alone would neutralize them today. They are overridden explicitly so the store stays
  // inert even if a future base-class change stops routing a mutator through `setState`.
  setState(_newState) {}
  update(_changes) {}
  set(_key, _value) {}
  notifyAll() {}
