react-hook-webstorage
react-hook-webstorage
offers a collection of React hooks designed to simplify the management of data on top of the Web Storage API and implements LocalStorage and SessionStorage. Whether you're building a small application or a large-scale project, these hooks provide an efficient way to handle persistent data in your React applications.
Components using the following hooks will rerender when another component changes the value of its controlled storage key. This is useful for updating the UI consistently.

Installation
To install react-hook-webstorage
, use your preferred package manager:
npm install react-hook-webstorage
# or
yarn add react-hook-webstorage
The hooks
All hooks return an object with the following properties:
value
: The current value stored in the storage for the specified key.setItem
: A function to set a new value for the specified key in the storage.removeItem
: A function to remove the value for the specified key from the storage.
useLocalStorage()
import { useLocalStorage } from 'react-hook-webstorage';
function Component() {
const { value, setItem, removeItem } = useLocalStorage('-key', {
parse: true,
fallback: 'default-value',
});
return (
// Your component JSX here
);
}
useSessionStorage
import { useSessionStorage } from 'react-hook-webstorage';
function Component() {
const { value, setItem, removeItem } = useSessionStorage('-key', {
parse: false,
fallback: null,
});
return (
// Your component JSX here
);
}
useWebStorage
The useWebStorage
hook provides a flexible foundation for creating custom storage solutions based on the Web Storage Interface. This allows developers to extend the library's functionality or implement specific storage requirements. Below is a guide on how to use useWebStorage
to build a custom storage solution.
Building Custom Storage with useWebStorage
Creating a Custom Storage Provider
To create a custom storage provider, implement the StorageProvider
interface.
Here's an example of a custom storage provider for a hypothetical CustomStorage
:
import { StorageProvider } from 'react-hook-webstorage';
export const CustomStorageProvider: StorageProvider = {
get name() {
return 'custom-storage';
},
get storage() {
// Implement your custom logic to get the storage instance
// This could be an in-memory storage, a database, or any other custom solution
return getCustomStorageInstance();
},
};
Using useWebStorage
with Custom Storage to build a custom hook
Now, you can use the useWebStorage
hook with your custom storage provider:
import { useWebStorage } from 'react-hook-webstorage';
import { CustomStorageProvider } from './CustomStorageProvider';
export type UseCustomStorageHookOptions<T = unknown> = UseWebStorageHookOptions<T>;
export type UseCustomStorageHookResult<T = unknown> = UseWebStorageHookResult<T>;
export type UseCustomStorageHook = typeof useCustomStorage;
export function useCustomStorage<T = unknown>(
key: string,
options: UseCustomStorageHookOptions<T> = {},
): UseCustomStorageHookResult<T> {
return useWebStorage<T>(CustomStorageProvider, key, options);
}
