What are the best practices for using sessionStorage in React?

When using sessionStorage in React, it's important to keep data size in mind, as it has a limit of about 5MB. Also, ensure that sensitive data is not stored, as sessionStorage is accessible via JavaScript.

How can I manage sessionStorage effectively in my components?

You can create a custom hook to manage sessionStorage. This hook can handle setting, getting, and removing items, making it easier to use throughout your components.

Can you show me an example of a custom hook for sessionStorage?

Sure! Here's a simple example:

import { useState, useEffect } from 'react';

function useSessionStorage(key, initialValue) {
    const [storedValue, setStoredValue] = useState(() => {
        try {
            const item = window.sessionStorage.getItem(key);
            return item ? JSON.parse(item) : initialValue;
        } catch (error) {
            console.error(error);
            return initialValue;
        }
    });

    useEffect(() => {
        try {
            window.sessionStorage.setItem(key, JSON.stringify(storedValue));
        } catch (error) {
            console.error(error);
        }
    }, [key, storedValue]);

    return [storedValue, setStoredValue];
}

This hook allows you to easily manage sessionStorage in your components.

What should I avoid when using sessionStorage?

Avoid storing large amounts of data, sensitive information, and ensure that you handle exceptions properly to prevent your app from crashing.
