VUE3 basic tutorial: Use Vue.js plug-in to encapsulate common UI components

Vue.js is a JavaScript framework for building interactive interfaces. It can handle componentized development very easily, which makes it very easy to build user interfaces in real applications. Vue.js 3 is its latest version and has many improvements and changes compared to previous versions. This article will introduce the process of using Vue.js 3, encapsulating and using common UI components.

Vue.js plugin

Vue.js plugin is a mechanism to provide global functionality or add functionality to a Vue instance. Plug-ins usually define one or more global methods, directives or filters and register them in the Vue instance. Plugins are very useful in the development of Vue.js applications as they make the development process smoother. In the Vue.js community, there are many open source common UI component libraries, such as Element UI and Ant Design Vue. These components can be used in your application through Vue.js plugins.

Encapsulating Vue.js UI components

Using the Vue.js plug-in, you can encapsulate custom UI components for reuse in multiple Vue.js applications. The process of encapsulating UI components in Vue.js 3 is very simple. Here is a simple example.

// MyComponent.vue

<script>
export default {
  name: 'MyComponent',
  props: {
    title: {
      type: String,
      required: true
    },
    content: {
      type: String,
      required: true
    }
  },
  template: `
    <div>
      <h2>{{ title }}</h2>
      <p>{{ content }}</p>
    </div>
  `
}
</script>

In the above example, we encapsulated a simple UI component named MyComponent. The component has two props, title and content, and a template, which is displayed when the component is rendered. We can use this component in Vue.js application like below.

<template>
  <div>
    <my-component title="Hello World" content="This is my first component"></my-component>
  </div>
</template>

<script>
import MyComponent from './MyComponent.vue'

export default {
  components: {
    MyComponent
  }
}
</script>

Add an import statement to our Vue.js application to import the MyComponent.vue file and use the components attribute to register MyComponent as a local component. We can now use this component in our application.

Instead of writing custom UI components yourself, it will be more convenient and time-saving to use popular UI libraries. In the Vue.js community, there are many UI component libraries that support Vue.js 3. Here are some popular examples:
