What are dynamic components in Vuejs explain with example? 079 

Dynamic components in Vue.js allow you to switch between different components within a single template element at runtime, based on conditions or data. This enables flexible and adaptive UI structures.

Key Concepts:

  • component directive: Dynamically binds a component to an element using the v-bind:is directive (shorthand: :).

  • Component resolution: Vue resolves the component based on:

  • String: Component name registered globally or locally.

  • Object: Component options object for inline component creation.


Code snippet

  <component :is="currentView"></component>

export default {
  data() {
    return {
      currentView: 'HomeView',
  components: {
    HomeView: { /* ... */ },
    ProfileView: { /* ... */ },
    SettingsView: { /* ... */ },


  1. The component directive binds the currentView data property to the is attribute.

  2. Vue renders the component corresponding to the value of currentView.

  3. Changing currentView to ProfileView or SettingsView dynamically switches the rendered component.

Common Use Cases:

  • Conditional rendering: Display different components based on conditions.

  • Tab-based navigation: Render different content for each tab.

  • Wizard-like interfaces: Guide users through multi-step forms or processes.

  • Loading states: Show loading indicators while fetching data.

  • Error boundaries: Render fallback UI for component errors.

Additional Features:

  • Keep-alive: Caches dynamic components to prevent re-rendering when switching back to them.

  • Async components: Load components asynchronously for improved initial load performance.


  • Flexibility: Adapt UI to different states without code duplication.

  • Modularity: Break down complex UIs into smaller, reusable components.

  • Code organization: Improve code structure and maintainability.

User experience: Create dynamic and interactive interfaces.
