Application practice of Vue3+TypeScript burying points

This article explains in detail how to use TypeScript to implement the buried point function in Vue3, including global registration of $track plug-in, Mixin to implement the global buried point, etc. With the gradual popularity of Vue3, it will become more and more popular to use Vue3+TypeScript to implement burying points in actual work.

1. Pre-knowledge

Before starting to add buried points to Vue3 projects, you need to prepare the following pre-knowledge:

1. Vue3: is a lightweight JavaScript framework used to build user interface

2. TypeScript: TypeScript is an open source programming language by Microsoft. It is a superset of the JavaScript language.

3. Buried points: Buried points are a data analysis technology that records the user's behavioral data in the product and then collects, analyzes and displays.

2. Vue3+TypeScript practice

In order for buried point code to be readable and maintainable, we need to modularize it. Take a simple burial point as an example:

// 
  export function track(eventName: string, eventData: any) {
    // Build the code to report    (`Track event: ${eventName}`);
  }

In the Vue3 project, we can register a $track plugin globally, the code is as follows:

// 
  import { App } from 'vue';
  import { track } from './track';
  export const trackPlugin = {
    install(app: App) {
      .$track = track;
    },
  };

Use the plugin in:

// 
  import { createApp } from 'vue';
  import App from './';
  import { trackPlugin } from './plugins/track-plugin';
  const app = createApp(App);
  (trackPlugin);
  ('#app');

Now we can easily use the $track plugin in Vue3 components, for example:

// 
  export default defineComponent({
    methods: {
      sendDataToTrack() {
        this.$track('button_click', { button_name: 'like_button' });
      },
    },
  });

3. TypeScript type declaration

To achieve more stringent and accurate type checking, we can add type declarations for the $track plugin. Take EventName and EventData as examples:

// 
  export type EventName = 'button_click' | 'page_view' | 'form_submit';
  export type EventData = { [key: string]: any };
  export function track(eventName: EventName, eventData: EventData): void;

4. Mixin realizes global burial

In Vue2, we can implement global burial points through Mixin. Vue3 also supports Mixin, but it is also recommended to use the Composition API. Taking Mixin's implementation of global click management as an example:

// 
  import { ComponentOptions } from 'vue';
  import { track } from './track';
  // Mixin
  const clickTracker: ComponentOptions = {
    methods: {
      // Add handlers manually      addClickTracker() {
        ('Mixin - click tracker added');
        const elements = ('[data-tracking-click]');
        for (let i = 0; i &lt; ; i++) {
          elements[i].addEventListener('click', (event) =&gt; {
            const target =  as Element;
            const eventName = ('data-tracking-click')!;
            const eventData = (('data-tracking-value')!);
            track(eventName, eventData);
          });
        }
      },
    },
    mounted() {
      ();
    },
    updated() {
      ();
    },
  };
  export default clickTracker;

Then, use Mixin in the component:

// 
  import { defineComponent } from 'vue';
  import clickTracker from './click-tracker';
  export default defineComponent({
    // Use Mixin    mixins: [clickTracker],
    methods: {
      sendDataToTrack() {
        // Build and report        this.$track('button_click', { button_name: 'add_cart_button' });
      },
    },
  });
