What are the differences between session storage and local storage in Vue.js?

What are the differences between session storage and local storage in Vue.js?

Session storage and local storage are both part of the Web Storage API, but they serve different purposes. Session storage is limited to the duration of the page session, meaning data is lost when the tab is closed. Local storage, on the other hand, persists even after the browser is closed, allowing data to be stored indefinitely until explicitly deleted.

Can you give me an example of how to use session storage in a Vue.js app?

Sure! You can use session storage in Vue.js like this:

// To set an item
sessionStorage.setItem('key', 'value');

// To get an item
const value = sessionStorage.getItem('key');

// To remove an item
sessionStorage.removeItem('key');

This allows you to store data temporarily while the user is on your site.

When should I use local storage instead of session storage?

Use local storage when you need to persist data across sessions, such as user preferences or settings. Session storage is better for temporary data that only needs to last as long as the user is on the page.

Are there any limitations to using local storage?

Yes, local storage has a size limit (usually around 5-10MB depending on the browser) and is synchronous, which can block the main thread. It's also not suitable for sensitive data since it's accessible via JavaScript.
