useLocalStorage

npm downloads bundle size

A React hook for managing local storage with built-in synchronization across tabs.

Installation

You can install the uselocalstorage-ts package via npm (or whatever):

npm install uselocalstorage-ts

Usage

The useLocalStorage hook allows you to easily read and write values from local storage. It also automatically synchronizes changes across different components of your application. Function setValueForLocalStorage allows you to change value wherever you want.

Example

import { useLocalStorage } from 'uselocalstorage-ts';

const MyComponent = () => {
	const { value: inputValue, setValueForLocalStorage: setValue } =
		useLocalStorage('myKey', 'defaultValue');

	return (
		<div>
			<input
				type='text'
				value={inputValue}
				onChange={(e) => setValue(e.target.value)}
			/>
			<p>Current Value: {value}</p>
		</div>
	);
};

// AnotherComponent.tsx
import { setValueForLocalStorage } from 'uselocalstorage-ts';

const AnotherMyComponent = () => {
	return (
		<button onClick={() => setValueForLocalStorage('myKey', 'AnotherValue')}>
			Change localStorage!{' '}
		</button>
	);
};

API

useLocalStorage

useLocalStorage(key: string, initialValue: InitialValue): { readonly value: Value | InitialValue; readonly setValueForLocalStorage: <NewValue>(newValue: NewValue) => void; readonly removeKeyFromLocalStorage: () => void; readonly clearLocalStorage: () => void; }

  • key: A string representing the key in local storage.
  • initialValue: The initial value to use if there is no value in local storage.
  • Returns: An object containing:
    • The current value from local storage (or the initial value),
    • A function to update the value in local storage,
    • A function to remove the key from local storage,
    • A function to clear ALL local storage keys.

setValueForLocalStorage

You can update local storage globally using the setValueForLocalStorage function:

import { setValueForLocalStorage } from 'uselocalstorage-ts';

setValueForLocalStorage('myKey', 'newValue');

This function updates the value and dispatches a storage event, allowing all components to react to the change.
