Free online courseVue 3 Step-by-Step Course: Components, Composition API, Vite and Pinia

Course Description

If you want to build modern, maintainable web interfaces, Vue 3 is one of the most practical ways to get there. This free online course guides you from the very first Vue fundamentals to the patterns developers rely on in real projects, helping you move beyond copy-pasting snippets and toward confidently designing your own app structure.

You’ll start by learning how Vue thinks: reactive state, data binding with directives, event handling, and the everyday building blocks that make forms and UI interactions feel effortless. As you progress, you’ll shift from small examples to a cleaner, component-based mindset, learning how to split your interface into reusable parts, pass data with props, and keep parent and child components aligned without turning your code into a tangled mess.

From there, you’ll deepen your understanding of productivity-focused features that make Vue stand out. You’ll work with computed properties for derived values, manage lists and conditionals the right way, and use keys to keep rendering predictable and efficient. You’ll also explore how slots unlock flexible component design, letting you create reusable UI pieces while still customizing content where you need it.

Once the foundation is solid, the course transitions into Vue 3’s Composition API and script setup, showing you how to build more scalable logic with refs and composables. You’ll see why some values update automatically and others don’t, how to structure reusable logic that can be shared across components, and how to react to changes over time using the right reactive tools.

To round out a workflow that matches modern frontend development, you’ll use Vite for a smoother developer experience with rapid feedback, then step into application-wide state management with Pinia. Instead of scattering shared data across components, you’ll learn to centralize state, create computed-like store values, and build a more reliable architecture for features like dashboards, counters, and shared app data. Along the way, short exercises reinforce key concepts so you’re not just watching, but actively building confidence you can apply immediately to your own Vue projects.
