React local storage hook
About the project
This package provides a react.js hook for using the local storage of a browser.
Installation
NPM
npm i --save @yannickfricke/use-local-storage
Yarn
yarn add @yannickfricke/use-local-storage
TypeScript support
This package includes TypeScript definition files - so with every good IDE you can read those declaration files and get auto complete for the API.
Usage examples
// Import the hook
import {
useLocalStorage,
useSyncedLocalStorage,
} from '@yannickfricke/use-local-storage/dist';
// The key defines the name of the entry
// which will be used to save the data
const usersKey = 'app.users';
// Define the settings key
// It will be used to save an object to the
// local storage
const settingsKey = 'app.settings';
// This returns a function which you can execute
// to get the users array from the local storage
export const getUsers = () => useLocalStorage(usersKey, []);
// Define the second argument as object to save
// this value. You can also define here a default state
// which will be saved when the value of the key is null
export const getSettings = () => useLocalStorage(settingsKey, {});
// HINT: The synced local storage will update its own value when
// another local storage instance updated the value.
// So the state will be syncronized across windows / tabs
export const getSettings = () => useSyncedLocalStorage(settingsKey, {});
HINT:
TypeScript users can also use generics to define the type of the state!
Then it will be correctly type hinted.
