How can I implement offline storage in Vue 3?

You can use the localStorage or IndexedDB APIs for offline storage in Vue 3. Would you like a code example?

Yes, please provide a code example using localStorage.

Sure! Here's a simple example:

export default {
  data() {
    return {
      userData: null,
    };
  },
  mounted() {
    this.loadUserData();
  },
  methods: {
    saveUserData(data) {
      localStorage.setItem('userData', JSON.stringify(data));
    },
    loadUserData() {
      const data = localStorage.getItem('userData');
      this.userData = data ? JSON.parse(data) : null;
    },
  },
};

This code saves and loads user data from localStorage.

What are the limitations of using localStorage?

LocalStorage has a size limit of about 5MB, is synchronous, and can only store strings. For larger data, consider IndexedDB.
