VUE3 basic tutorial: Use Vue.js plug-in to encapsulate the dividing line component

Vue.js is a popular front-end framework that provides a wealth of plug-ins and components, allowing us to develop web applications more conveniently.

This article introduces how to use the Vue.js plug-in to encapsulate a dividing line component. Using this component in a web application can make the page more beautiful and easier to read.

1. Install Vue.js

Before we begin, we need to install Vue.js first. Generally, we can use npm to install Vue.js in the command line. If you haven't installed npm yet, please install npm first.

Execute the following command in the command line:

npm install vue

2. Create a dividing line component

We can use Vue.js to create a dividing line component. In this component, we can use HTML and CSS to define the style of the dividing line.

Execute the following command in the command line to create a new Vue.js component project:

vue create separation-line

In the src/components directory, create a file SeparationLine.vue with the following code:

<template>
  <div class="separation-line"></div>
</template>

<style>
.separation-line {
  border-bottom: 1px solid #ccc;
  margin: 20px 0;
}
</style>

In the above code, we define a Vue.js component named SeparationLine. In the

We use CSS to style the dividing line. In the .separation-line class, we set the color of the separation line to #ccc, the border thickness to 1 pixel, and the top and bottom spacing to 20 pixels.

3. Encapsulate it into a Vue.js plug-in

Now we have created a dividing line component named SeparationLine. For ease of use and reuse, we encapsulate it into a Vue.js plug-in, which can be used in multiple projects.

In the src/plugins directory, create a file separation-line.js with the following code:

import SeparationLine from '@/components/SeparationLine.vue';

const plugin = {
  install(Vue) {
    Vue.component('SeparationLine', SeparationLine);
  }
};

export default plugin;

In this code, we define a component named SeparationLine and add it Encapsulated into a Vue.js plug-in. In this plugin, we use the Vue.component() method to register this component so that it can be used in the template. Finally, we export the plugin.

4. Use the dividing line component

Now we have encapsulated the dividing line component into a Vue.js plug-in. We can use this component in Vue.js application.

First, import the plug-in in the main.js file:

import Vue from 'vue';
import SeparationLinePlugin from './plugins/separation-line';

Vue.use(SeparationLinePlugin);

new Vue({
  el: '#app',
  render: h => h(App)
});

In Vue.js, we use the Vue.use() method to load the plug-in. In the above code, we loaded the SeparationLinePlugin plugin.

Next, use the SeparationLine component in the template:

<template>
  <div>
    <h1 id="Title">Title 1</h1>
    <separation-line></separation-line>
    <h2 id="Title">Title 2</h2>
    <separation-line></separation-line>
    <h3 id="Title">Title 3</h3>
    <separation-line></separation-line>
  </div>
</template>

In the above code, we use three SeparationLine components to separate the three titles. You can adjust the position and number of components yourself to suit your needs.
