How can I use session storage in my React app?
You can use the sessionStorage
API to store data for the duration of the page session. In React, you can set and get session storage values using sessionStorage.setItem(key, value)
and sessionStorage.getItem(key)
.
Can you show me a code example?
Sure! Here's a simple example:
import React, { useEffect } from 'react';
const MyComponent = () => {
useEffect(() => {
sessionStorage.setItem('myData', 'Hello, World!');
}, []);
const data = sessionStorage.getItem('myData');
return <div>{data}</div>;
};
What happens if I refresh the page?
The data stored in sessionStorage
will persist even if you refresh the page, but it will be cleared when the tab or browser is closed.
Is there a limit to how much I can store?
Yes, most browsers have a limit of about 5MB for sessionStorage
, but this can vary slightly between different browsers.
