How can I use local storage in Vue.js for advanced features?

You can use the localStorage API in Vue.js to store data persistently. For advanced features, consider creating a Vuex store that syncs with local storage.

Can you show me an example of syncing Vuex with local storage?

Sure! You can create a Vuex plugin that saves the state to local storage whenever it changes. Here's a simple example:

const localStoragePlugin = store => {
  store.subscribe((mutation, state) => {
    localStorage.setItem('myAppState', JSON.stringify(state));
  });
};

Then, use this plugin when creating your store.

What about retrieving data from local storage when the app loads?

You can retrieve the data in the created lifecycle hook of your main Vue instance. For example:

const savedState = localStorage.getItem('myAppState');
if (savedState) {
  store.replaceState(JSON.parse(savedState));
}

Are there any limitations I should be aware of with local storage?

Yes, local storage has a size limit (usually around 5MB) and is synchronous, which can block the main thread. Use it wisely!
