Storage

useLocalStorage

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.

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');
  // ...

Scheduling

useEventListener

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);
      // ...
    }
