How can I troubleshoot issues with localStorage in my web app?

I'm having trouble with localStorage in my web app. It doesn't seem to save data.

Let's start by checking if you're using the correct methods to set and get items from localStorage. Can you share your code?

Sure! I'm using localStorage.setItem('key', 'value') but when I try to retrieve it with localStorage.getItem('key'), it returns null.

It sounds like there might be an issue with how you're accessing localStorage. Are you running this code in a secure context (HTTPS)?

Yes, I'm using HTTPS. I also checked the browser console for errors, but there are none.

In that case, ensure that your code is executing after the DOM is fully loaded. You might want to wrap it in a DOMContentLoaded event listener.
