Vite is an alternative to the Vue CLI and uses Vue 3 by default. It's noticeably faster because it does NOT use webpack to bundle your code and instead makes use of native ES module imports. We’ll be using Vite throughout this series so it's a good idea to quickly get familiar with it.

Vue 3 no longer requires a single root node for components. Let's review a few examples, while also discussing how to satisfy the linting rules in VSCode.

Teleport was ported from the popular Portal Vue library in Vue 2. It allows you to render pieces of code in other parts of the DOM.

Let's take a look at the change detection caveats for objects and arrays that were present in Vue 2. Vue 3 fixes these as they move towards a proxy-based API for change detection.

Let’s take a look at the ability to add multiple v-models on a custom component. This allows you to keep state synchronized between a parent and a child component.

Let's discuss the Global API changes in Vue 3, and the ability to use instance methods as opposed to global methods in Vue 2. Further, we'll take a look at Global Tree Shaking.

Suspense allows us to render fallback content before your component is ready to be rendered. It’s a cleaner way to handle loading states using a Suspense component and different slots for each of the states.

Note: This is an experimental feature and subject to change.
