use-synced-storage

React Hook to manage {local,sessions,*}storage with syncing across components and tabs

Quick Start

import React from 'react';
import { useLocalStorage } from 'use-storage/src/index';

export const MyComponent: React.FunctionComponent = () => {
  const [state, setState] = useLocalStorage('state', { count: 0 });

  return (
    <div>
      state.count is {state.count}
      <button onClick={() => setState({ count: (state.count) + 1 })}>++</button>
    </div>
  );
}

The state will sync across components and tabs

API

This module exports a createUseStorage function as well as a useLocalStorage and useSessionStorage hook.

The storage hooks api take the following options:

type Options<T> = {
  /** Customize encoding and decoding the object */
  serializer?: Serializer<T>;
  /** Time to live for entry in milliseconds */
  ttl?: number;
  /** Interval polling for updates in the background, this needs to be enabled for checking ttl didn't expire after the component rendered. Defaults to 1000 */
  pollingInterval?: number | false;
  /** Only check ttl when loading value and NOT periodically throughout the life of the component */
  checkTtlOnlyOnLoad?: boolean;
};
