vue3 class

Vue 3 introduces a new way of creating components using the class syntax. With the class-based API, you can define your components as classes, which makes it easier to organize and reuse code. Here's an example of how you can create a Vue component using the class syntax in Vue 3:

import { defineComponent } from 'vue';

class MyComponent extends Vue {
  // Component logic goes here
}

const MyVueComponent = defineComponent(MyComponent);

export default MyVueComponent;

In this example, we define a class called `MyComponent` that extends the `Vue` class. Inside the class, you can define data properties, computed properties, methods, and lifecycle hooks just like you would in the options API.

To create an instance of the component, we use the `defineComponent` function provided by Vue. This function takes the class and returns a Vue component that can be used in your templates.

Note that the class-based API is an alternative to the options API, and you can still use either approach to create your components in Vue 3.
