Cookies vs Local Storage: Which is Better?

What are the main differences between cookies and local storage?

Cookies are small pieces of data stored on the client side, sent to the server with each request, while local storage is a web storage solution that allows you to store data in the browser without sending it to the server.

When should I use cookies instead of local storage?

Use cookies when you need to send data to the server with each request, like session identifiers. Local storage is better for storing larger amounts of data that don't need to be sent to the server.

Are there any size limitations for cookies and local storage?

Yes, cookies typically have a size limit of about 4KB, while local storage can hold around 5-10MB depending on the browser.

Can I store sensitive information in local storage?

It's not recommended to store sensitive information in local storage, as it can be accessed by any script running on the page. Use secure methods for sensitive data.
