VUE3 Getting Started Tutorial: Using the Vue.js plug-in to encapsulate the timeline component

Vue.js is a very popular JavaScript framework that is widely used in front-end development. With the continuous development of Vue.js, new versions of VUE3 have also been launched one after another. This article will introduce an introductory tutorial on how to use the Vue.js plug-in to encapsulate the timeline component.

First, we need to understand the basic structure of the timeline component. The timeline component can be used to display events over a period of time, including time and event content. Generally, the timeline is arranged in the order in which events occurred, allowing users to more intuitively understand the relationship between events on the timeline. Here, we will use Vue.js to implement this function.

Next, we need to install Vue.js. You can complete the installation in the command line through the following instructions:

npm install vue

After the installation is complete, we can start building the timeline component. First, we need to create a Vue.js component. In this component we need to define data and methods.

In the component, we need to define a data object to store the component's data. This data object can include many attributes, such as time, event description, etc. Here we only define five properties:

data() {
  return {
    events: [
      { time: "2022-01-01", event: "New Year's Day" },
      { time: "2022-02-12", event: "Chinese New Year" },
      { time: "2022-04-15", event: "Tax Day" },
      { time: "2022-05-09", event: "Mother's Day" },
      { time: "2022-06-20", event: "Father's Day" }
    ]
  }
}

In this data object, we use an events array to store events. Each element in the array includes two attributes: time and event. The time attribute indicates the time when the event occurred, and the event attribute indicates the specific event content.

Next, we need to define a method for rendering the HTML structure of the timeline in the Vue.js component. In this method, we iterate through the events array and generate an HTML element for each event. Here we use the template syntax of Vue.js to create and update DOM elements.

methods: {
  renderTimeline() {
    return this.events.map(event => {
      return `<div>
                <div class="time">${event.time}</div>
                <div class="event">${event.event}</div>
              </div>`
    }).join('')
  }
}

In this method, we use the map method to traverse the events array. For each element in the array, we create a div element containing time and event and concatenate them into a string. Finally, we use the join method to concatenate all the strings into an HTML string and return it.

Now we have completed most of the construction of the timeline component. In order to use this component more conveniently, we need to use the Vue.js plug-in to encapsulate it. Here is the structure of a basic timeline plugin:

const TimelinePlugin = {
  install(Vue) {
    Vue.component('timeline', {
      data() {},
      methods: {},
      template: `<div class="timeline-container">{{renderTimeline()}}</div>`
    })
  }
}

In this plugin, we use two main parts: plugins and components. A plug-in is a functional module that can be registered and installed in a Vue.js instance. Here, we use the install method of Vue.js to install this plug-in. This method needs to receive Vue.js as a parameter and register our component as a global component.

The component is the timeline component we defined. Here, we write the data, methods and template we defined previously in Vue.component and register it as a timeline component. Finally, we splice it into a div container with class timeline-container.

Next, we need to import this plugin into our Vue.js application. You can do it like this in main.js:

import Vue from 'vue'
import TimelinePlugin from './timeline-plugin.js'

Vue.use(TimelinePlugin)

new Vue({ 
  el: '#app'
})

In main.js, we use the import statement to import the TimelinePlugin plugin into our application. Then, we use the use method of Vue.js to install the plugin. Finally, we create a Vue.js instance and bind it to a DOM element with the id #app.

Finally, we need to create a DOM element in the html file to render the timeline component. You can do this:

<html>
  ...
  <body>
    <div id="app">
      <timeline></timeline>
    </div>
    <script src="js/main.js"></script>
  </body>
</html>

In this HTML example, we create a div container with the id #app and insert the timeline component into it. Finally, we set the main.js file as the page's script file and import it into the html.

Now, we have completed a basic timeline component and encapsulated it as a Vue.js plugin. You can use it very conveniently in Vue.js applications. If you want to know more about how Vue.js and VUE3 work, check out the relevant documentation.
