How to use vue componentizationApr 17, 2023 am 11:27 AM

With the development of front-end technology, Vue has become an indispensable part of modern web development. As an MVVM framework, Vue mainly builds user interfaces through data binding and component systems.

Vue’s componentized system allows developers to develop web applications in a more modular and reusable way, which is even more essential in large applications. This article will introduce Vue componentization and demonstrate how to use components in Vue applications.

  1. Basic of Vue componentization

In Vue, a component is composed of three parts:

  • Template
  • Data
  • Behavior

Components can be used alone or in combination with multiple components. Each component can have its own data, behavior and templates.

  1. How to define Vue components

Vue components can be defined through component options. Each Vue component must define at least one template and one data object. The following is a simple Vue component definition example:

Vue.component('my-component', {
  template: '<div>{{ message }}</div>',
  data() {
    return {
      message: 'Hello, Vue!'
    };
  }
});

In this example, we define a component named "my-component" whose template defines a <div> element, in which the value of the component data object <code>message is rendered. We can also add other properties and methods to this component:

Vue.component('my-component', {
  template: '<div>{{ message }}</div>',
  data() {
    return {
      message: 'Hello, Vue!'
    };
  },
  methods: {
    showMessage() {
      alert(this.message);
    }
  }
});

In this example, we added a method named "showMessage", which is used to pop up a message box and display the component data object (message) value.

  1. Register component

We need to register the component in the Vue instance before we can use it in the application.

var vm = new Vue({
  el: '#app',
  components: {
    'my-component': {
      template: '<div>{{ message }}</div>',
      data() {
        return {
          message: 'Hello, Vue!'
        };
      }
    }
  }
});

In this example, we make the component available in the application by registering the component my-component in the component options of the Vue instance.

  1. Nested components

We can reference another component in one component. This component nesting method is an important means to achieve component development in Vue.

Vue.component('my-component', {
  template: '<div><my-child></my-child></div>',
  components: {
    'my-child': {
      template: '<p>Child component</p>'
    }
  }
});

In this example, we define a component named "my-component" and nest a sub-component named "my-child" in the template. Note that we used the <my-child></my-child> tag on the child component, which is how the component is referenced.

  1. Component communication

In Vue applications, communication between components is very common. In Vue, the parent component can pass data to the child component through Props, and the child component can pass the emit event, and finally pass the event to the parent component. The following is an example of a parent component passing data to a child component:

Vue.component('child-component', {
  template: '<p>{{ message }}</p>',
  props: ['message']
});

Vue.component('parent-component', {
  template: '<div><child-component></child-component></div>',
  data() {
    return {
      parentMessage: 'Data from parent component'
    };
  }
});

In this example, the value of parentMessage in the parent component is passed to the child component, and the child component is bound through the attribute to receive the data. In child components, we can specify which properties can be received from the parent component by using the props attribute.

  1. Summary

Componentization is a very important concept in Vue. Through Vue’s component system, we can separate different parts of the web page from each other, thereby making the code more Modular, reusable and maintainable. In this article, we introduced how Vue components are defined, registered, nested and communicated. I hope this article can provide you with some help in the development of Vue.
