useDocumentVisibility

Tracks visibility of the page.

Examples

function Component() {
  const documentVisibility = useDocumentVisibility();
  if (documentVisibility === 'hidden') {
    // Reduce resource utilization to aid background page performance
  }
  // ...
}

Returns VisibilityState Visibility state of the document, which is 'visible' by default.

useFocus

Tracks focus state of an element.

Examples

function Component() {
  const [isFocused, bindFocus] = useFocus();
  // ...
  return <ElementToObserve {...bindFocus} />;
}

Returns [boolean, Readonly<{onFocus: function (): void, onBlur: function (): void}>] Whether the element has focus, and props to be spread over the element under observation.

useGeolocation

Tracks geolocation of the device.

Parameters

• options PositionOptions? Additional watching options.
• errorCallback function (error: PositionError): void? Method to execute in case of an error, e.g. when the user denies location sharing permissions.

Examples

function Component() {
  const geolocation = useGeolocation();
  if (geolocation) {
    const { coords } = geolocation;
  }
  // ...
}

Returns (Position | undefined) Locational data, or undefined when unavailable.

useHover

⚠️ This attribute is inherently unreliable. A computer can be connected to a network without having internet access.

Examples

function Component() {
  const isOnline = useNetworkAvailability();
  // ...
}

Returns boolean false if the user agent is definitely offline, or true if it might be online.

useNetworkInformation

⚗️ The underlying technology is experimental. Please be aware about browser compatibility before using this in production.

Examples

function Component() {
  const networkInformation = useNetworkInformation();
  if (networkInformation) {
    const { effectiveType, downlink, rtt, saveData } = networkInformation;
  }
  // ...
}

Returns (NetworkInformation | undefined) Connection data, or undefined when unavailable.

useSize

Tracks size of an element.

⚗️ The underlying technology is experimental. Please be aware about browser compatibility before using this in production.

Parameters

• ref React.RefObject<HTMLElement> Attribute attached to the element under observation.
• ResizeObserverOverride TypeOf<ResizeObserver> Replacement for window.ResizeObserver, e.g. a polyfill.

Examples

function Component() {
  const ref = useRef < HTMLElement > null;
  const [width, height] = useSize(ref);
  // ...
  return <ElementToObserve ref={ref} />;
}

Returns Readonly<[number, number]> Dimensions [width, height], falling back to [0, 0] when unavailable.

useViewportScale

Storage

useLocalStorage

• See: useState hook, which exposes a similar interface

Stores a key/value pair statefully in localStorage.

Parameters

• key string Identifier to associate the stored value with.
• initialValue (T | function (): T | null) Value used when no item exists with the given key. Lazy initialization is available by using a function which returns the desired value. (optional, default null)
• errorCallback function (error: (DOMException | TypeError)): void? Method to execute in case of an error, e.g. when the storage quota has been exceeded or trying to store a circular data structure.

Examples

function Component() {
  const [visitCount, setVisitCount] =
    useLocalStorage < number > ('visitCount', 0);
  useEffect(() => {
    setVisitCount((count) => count + 1);
  }, []);
  // ...
}

Returns [T, React.Dispatch<React.SetStateAction<T>>] A statefully stored value, and a function to update it.

useSessionStorage

• See: useState hook, which exposes a similar interface

Stores a key/value pair statefully in sessionStorage.

Parameters

• key string Identifier to associate the stored value with.
• initialValue (T | function (): T | null) Value used when no item exists with the given key. Lazy initialization is available by using a function which returns the desired value. (optional, default null)
• errorCallback function (error: (DOMException | TypeError)): void? Method to execute in case of an error, e.g. when the storage quota has been exceeded or trying to store a circular data structure.

Examples

function Component() {
  const [name, setName] = useSessionStorage < string > ('name', 'Anonymous');
  // ...
}

Returns [T, React.Dispatch<React.SetStateAction<T>>] A statefully stored value, and a function to update it.

Scheduling

useEventListener

• See: Event reference on MDN

Listens to an event while the enclosing component is mounted.

Parameters

• target EventTarget Target to listen on, possibly a DOM element or a remote service connector.
• type string Name of event (case-sensitive).
• callback EventListener Method to execute whenever the event fires.
• options AddEventListenerOptions? Additional listener characteristics.

Examples

function Component() {
  useEventListener(window, 'error', () => {
    console.log('A resource failed to load.');
  });
  // ...
}

Returns void

useInterval

Repeatedly calls a function with a fixed time delay between each call.

📝 Timings may be inherently inaccurate, due to the implementation of setInterval under the hood.

Parameters

• callback function (): void Method to execute periodically.
• delayMs (number | null) Time, in milliseconds, to wait between executions of the specified function. Set to null for pausing.

Examples

function Component() {
  useInterval(() => {
    // Custom logic to execute each second
  }, 1000);
  // ...
}

Returns void

Performance tips

• Avoid layout thrashing by debouncing or throttling high frequency events, e.g. scrolling or mouse movements

• Move non-primitive hook parameters to an outer scope or memoize them with useMemo, e.g.:

  const geolocationOptions = { enableHighAccuracy: true };
  function Component() {
    const geolocation = useGeolocation(geolocationOptions);
    // ...
  }
