About the Vue Component Fundamentals with the Composition API course

Learn everything you need to know to get started with Vue components and the composition API. Components are the building blocks of any Vue.js application, allowing you to encapsulate and reuse functionality efficiently. Components combine HTML, JavaScript, and CSS, giving you the power to create modular, maintainable, and scalable applications.

📝 NOTE: If you are looking to write components with the Options API, we've got a course for that too but we recommend using the Composition API.

Why Components Matter in Vue.js

In Vue.js, components are like custom HTML elements (e.g., <p>, <button>, <header>), but with much more power. They let you define specific pieces of functionality that can be easily reused across your application, enhancing maintainability and scalability.

After completing this course, you'll be confident in:

  • Understanding how Vue.js components work and why they are essential in modern web development.
  • Communication between components using props and custom events to pass data and trigger actions.
  • The difference between global and local component registration, and when to use each.
  • Lifecycle hooks in Vue.js components and how to manage component states over time.
  • Component composition, including working with nested components and slots for flexible layouts.
  • Following best practices for Vue.js components, while avoiding common pitfalls.

We've also included practical exercises to help reinforce your learning:
