How to Use Local Storage in React with a Custom Hook
Discover how to use local storage in React and create a custom hook for enhanced functionality.
When building web applications, managing data efficiently is key. Local storage offers a simple way to store data in the user's browser, allowing us to persist state across page reloads. Let's dive into how we can use local storage in JavaScript and then see how we can integrate it beautifully in a React application using a custom hook.
Local Storage Basics
Local storage is a part of the Web Storage API, we can use it directly without any setup. Here's how we can interact with local storage using JavaScript:
Setting an Item
We can set an Item using a key-value pair.
Getting an Item

Removing an Item
Similarly, this applies to removing items as well.
Clearing All Items
This clears all keys and values from local storage.
Creating a Custom Hook in React
Now that we've gone over the basics, let's create a custom hook to use in React.
To make local storage management more reusable and React-friendly, we can create a custom hook called useLocalStorage
. This hook will handle setting, getting, and removing items seamlessly.
