What are the differences between localStorage and cookies in Vue.js?

What are the differences between localStorage and cookies in Vue.js?

LocalStorage and cookies are both used for storing data in the browser, but they have key differences. LocalStorage can store larger amounts of data (up to 5MB) and is accessible only on the same origin. Cookies, on the other hand, are limited to 4KB and can be sent with HTTP requests, making them suitable for session management.

When should I use localStorage instead of cookies?

You should use localStorage when you need to store larger amounts of data that don't need to be sent to the server with every request. It's great for persisting user preferences or application state.

Are there any security concerns with using localStorage?

Yes, localStorage is vulnerable to XSS attacks since any script running on the page can access it. Always validate and sanitize user inputs to mitigate risks.

Can I use both localStorage and cookies together?

Absolutely! You can use localStorage for larger data and cookies for session management or data that needs to be sent to the server.
