Developing Vue Apps with Class-Based Components — TypeScript, Superclasses, and Mixins

Developing Vue Apps with Class-Based Components — TypeScript, Superclasses, Hooks, and Mixins. We can add props and inherit superclass components with the mixins method in our Vue TypeScript project. TypeScript, Superclasses, and Mixins. Type annotation within our Vue class-based components written in TypeScript.

If we prefer to use classes, we can use the class-based components API that comes with Vue.

In this article, we’ll look at how to developing Vue apps with class-based components.

TypeScript, Superclasses, and Mixins

We can add props and inherit superclass components with the mixins method in our Vue TypeScript project.

For instance, we can write:

<template>
  <div>
    <p>{{ message }}</p>
  </div>
</template>
<script lang="ts">
import Vue from "vue";
import Component, { mixins } from "vue-class-component";
const GreetingProps = Vue.extend({
  props: {
    name: String,
  },
});
@Component
class Super extends Vue {
  lastName = "smith";
}
@Component
export default class HelloWorld extends mixins(GreetingProps, Super) {
  get message(): string {
    return `Hello, ${this.name} ${this.lastName}`;
  }
}
</script>

We create the Super component class with the 1astName property.

And we have the GreetProps class that we create with the Vue.extend method so we can accept props in a way that’s acceptable by TypeScript.

Then we call the mixins method with the GreetProps and Super methods so we can inherit from both classes.

We inherit from both classes, so this.name is 'james' and this.lastName is 'smith' .

We can define properties with type definitions.
