VUE3 Getting Started Tutorial: Using the Vue.js plugin to encapsulate map components

Vue.js is a popular JavaScript framework that makes it easy to create interactive and data-driven web applications. Vue.js has an interface and API that is easy to learn and use, making it the choice of many front-end developers. In this article, we will introduce how to use the Vue.js plug-in to encapsulate the map component so that you can quickly integrate map functions in your Vue.js application.

First, we need to install the Vue.js plugin so that we can use the map component. In Vue.js 3, we can use the new feature of Vue 3 - Composition API to write plug-ins, and we can also use the Vue.js life cycle function to initialize and destroy map components. Then we can install the necessary dependencies through npm:

npm install --save vue vue2-google-maps

Among them, vue is the Vue.js framework itself, and vue2-google-maps is based on Google Maps The Vue.js plug-in of the API can provide map-related components and services.

Next, we can create a Vue.js plug-in and register the map component. Here is a simple demonstration of a map component using the vue2-google-maps plug-in:

import { googleMapsApi } from 'vue2-google-maps';

const MapComponent = {
  template: `
    <div>
        <h2>{{ title }}</h2>
        <GmapMap :zoom="zoom" :center="center">
            <GmapMarker :position="center" />
        </GmapMap>
    </div>
  `,
  name: 'MapComponent',
  props: {
    title: { type: String, default: 'Map Component' },
    zoom: { type: Number, default: 12 },
    center: { type: Object, default: () => ({ lat: 51.5287718, lng: -0.2416815 }) },
  },
  components: {
    GmapMap: googleMapsApi.Map,
    GmapMarker: googleMapsApi.Marker,
  },
};

export default {
  install: (app, options) => {
    app.component(MapComponent.name, MapComponent);
  },
};

In the above code, we created a map component named MapComponent, As well as the Vue.js plug-in, the googleMapsApi object provided by the vue2-google-maps plug-in is used. We register the component into the Vue.js application and pass the standard Vue.js options object app, as well as other optional options options. We use the component options object for configuration, including providing the component's template, name, and properties; and introducing the component in Vue.js. This component can be rendered by including the MapComponent tag in the Vue component, here is an example:

<MapComponent title="My Location" :center="myLocation" />

In the above example, we passed a center attribute to MapComponent component so that we can dynamically specify the center of the map. In this example, we use a myLocation variable that contains the geographic coordinates of the user's current location.

Finally, in order to use the map component correctly, we also need to implement the map's life cycle function in the Vue.js component to initialize and destroy the map. The sample code is as follows:

import { onMounted, onUnmounted } from 'vue';

export default {
  data() {
    return {
      map: null,
    };
  },
  methods: {
    initMap() {
      this.map = new google.maps.Map(this.$refs.mapContainer, {
        center: this.center,
        zoom: this.zoom,
      });
    },
    destroyMap() {
      this.map = null;
    },
  },
  mounted() {
    onMounted(() => {
      this.initMap();
    });
  },
  beforeUnmount() {
    onUnmounted(() => {
      this.destroyMap();
    });
  },
};

In the above code, we use the onMounted and onUnmounted functions provided by Vue.js to monitor component mounting and destruction events, and The initMap and destroyMap methods are called in these events to initialize and destroy the map.

In this article, we introduce how to use the Vue.js plug-in to encapsulate the map component, which is an effective way to easily obtain map functionality in a Vue.js application. We introduced the vue2-google-maps plugin and created a Vue.js plugin to register the map component, and then implemented a Vue.js component containing map initialization and destruction logic. In this way, we can use the powerful functions of Vue.js to easily build interactive and data-driven web applications, allowing us to deeply feel the convenience that Vue.js brings to us.
