Getting Started with the Vue Maps Component in Vue 3

28 Feb 202619 minutes to read

This article provides a step-by-step guide for setting up a Vite project with a JavaScript environment and integrating the Syncfusion® Vue Bullet Chart component using the Composition API / Options API.

The Composition API is a new feature introduced in Vue.js 3 that provides an alternative way to organize and reuse component logic. It allows developers to write components as functions that use smaller, reusable functions called composition functions to manage their properties and behavior.

The Options API is the traditional way of writing Vue.js components, where the component logic is organized into a series of options that define the component’s properties and behavior. These options include data, methods, computed properties, watchers, life cycle hooks, and more.

Prerequisites

System requirements for Syncfusion® Vue UI components

Setup the Vite project

A recommended approach for beginning with Vue is to scaffold a project using Vite. To create a new Vite project, use one of the commands that are specific to either NPM or Yarn.

npm create vite@latest

or

yarn create vite

Using one of the above commands will lead you to set up additional configurations for the project as below:

  1. Define the project name: We can specify the name of the project directly. Let’s specify the name of the project as my-project for this article.
? Project name: » my-project
  1. Select Vue as the framework. It will create a Vue 3 project.
? Select a framework: » - Use arrow-keys. Return to submit.
Vanilla
> Vue
  React
  Preact
  Lit
  Svelte
  Others
  1. Choose JavaScript as the framework variant to build this Vite project using JavaScript and Vue.
? Select a variant: » - Use arrow-keys. Return to submit.
> JavaScript
  TypeScript
  Customize with create-vue ↗
  Nuxt ↗
  1. Upon completing the aforementioned steps to create the my-project, run the following command to install its dependencies:
cd my-project
npm install

or

cd my-project
yarn install

Now that my-project is ready to run with default settings, let’s add Syncfusion® components to the project.

Add Syncfusion® Vue packages

Syncfusion® Vue component packages are available at npmjs.com. To use Syncfusion® Vue components in the project, install the corresponding npm package.

This guide uses the Vue Maps component as an example. Install the @syncfusion/ej2-vue-maps package using the following command:

npm install @syncfusion/ej2-vue-maps --save

or

yarn add @syncfusion/ej2-vue-maps

The –save will instruct NPM to include the range navigator package inside of the dependencies section of the package.json.

Add Syncfusion® Vue component

  1. Import and register the Maps component and its child directives in the src/App.vue file. The import structure differs slightly between the two APIs:
    • Composition API: Add the setup attribute to the <script> tag and use Maps.Inject() for module injection
    • Options API: Use standard component registration with a provide option for module injection
<script setup>
  import { MapsComponent as EjsMaps, LayersDirective as ELayers, LayerDirective as ELayer, MapAjax, Legend, DataLabel, MapsTooltip } from '@syncfusion/ej2-vue-maps';
  import { Maps } from '@syncfusion/ej2-maps';
  Maps.Inject(Legend, DataLabel, MapsTooltip);
</script>
<script>
import { MapsComponent, LayersDirective, LayerDirective, MapAjax, Legend, DataLabel, MapsTooltip } from '@syncfusion/ej2-vue-maps'
//Component registration
export default {
  name: "App",
  components: {
    'ejs-maps' : MapsComponent,
    'e-layers' : LayersDirective,
    'e-layer' : LayerDirective
  },
  provide: {
    maps: [Legend, DataLabel, MapsTooltip]
  }
}
</script>
  1. Define the Maps component template with layer, title, legend, and other property bindings:
<template>
   <ejs-maps :titleSettings='titleSettings' :legendSettings='legendSettings'>
        <e-layers>
            <e-layer :shapeData='shapeData' :shapePropertyPath='shapePropertyPath' :shapeDataPath='shapeDataPath' :dataSource='dataSource' :shapeSettings='shapeSettings' :dataLabelSettings='dataLabelSettings' :tooltipSettings='tooltipSettings'></e-layer>
        </e-layers>
    </ejs-maps>
</template>
  1. Declare the property values referenced in the template:
<script setup>
    const titleSettings =  {
        text: 'UN security council countries'
    };
    const shapeData = new MapAjax('https://cdn.syncfusion.com/maps/map-data/world-map.json');
    const dataSource =  [{  "Country": "China", "Membership": "Permanent"},
            {"Country": "France","Membership": "Permanent" },
            { "Country": "Russia","Membership": "Permanent"},
            {"Country": "Kazakhstan","Membership": "Non-Permanent"},
            { "Country": "Poland","Membership": "Non-Permanent"},
            {"Country": "Sweden","Membership": "Non-Permanent"}];
    const shapePropertyPath = 'name';
    const shapeDataPath = 'Country';
    const shapeSettings = {
            colorValuePath: 'Membership',
            colorMapping: [
                {
                    value: 'Permanent', color: '#D84444'
                },
                {
                    value: 'Non-Permanent', color: '#316DB5'
                }
            ]
    };
    const dataLabelSettings = {
            visible: true,
            labelPath: 'name',
            smartLabelMode: 'Trim'
    };
    const legendSettings = {
        visible: true
    };
    const tooltipSettings = {
        visible: true,
        valuePath: 'Country'
    };
</script>
<script>
data() {
  return {
    titleSettings: {
        text: 'UN security council countries'
    },
    shapeData: new MapAjax('https://cdn.syncfusion.com/maps/map-data/world-map.json'),
    dataSource: [{  "Country": "China", "Membership": "Permanent"},
            {"Country": "France","Membership": "Permanent" },
            { "Country": "Russia","Membership": "Permanent"},
            {"Country": "Kazakhstan","Membership": "Non-Permanent"},
            { "Country": "Poland","Membership": "Non-Permanent"},
            {"Country": "Sweden","Membership": "Non-Permanent"}],
    shapePropertyPath: 'name',
    shapeDataPath: 'Country',
    shapeSettings: {
            colorValuePath: 'Membership',
            colorMapping: [
                {
                    value: 'Permanent', color: '#D84444'
                },
                {
                    value: 'Non-Permanent', color: '#316DB5'
                }
            ]
    },
    dataLabelSettings: {
            visible: true,
            labelPath: 'name',
            smartLabelMode: 'Trim'
    },
    legendSettings: {
        visible: true
    },
    tooltipSettings: {
        visible: true,
        valuePath: 'Country'
    }
  };
}
</script>

Here is the complete code combining all steps in the src/App.vue file:

<template>
    <ejs-maps :titleSettings='titleSettings' :legendSettings='legendSettings'>
        <e-layers>
            <e-layer :shapeData='shapeData' :shapePropertyPath='shapePropertyPath' :shapeDataPath='shapeDataPath' :dataSource='dataSource' :shapeSettings='shapeSettings' :dataLabelSettings='dataLabelSettings' :tooltipSettings='tooltipSettings'></e-layer>
        </e-layers>
    </ejs-maps>
</template>

<script setup>

import { Maps } from '@syncfusion/ej2-maps';
Maps.Inject(Legend, DataLabel, MapsTooltip);
    const titleSettings =  {
        text: 'UN security council countries'
    };
    const shapeData = new MapAjax('https://cdn.syncfusion.com/maps/map-data/world-map.json');

    const shapePropertyPath = 'name';
    const shapeDataPath = 'Country';

                },
                {
                    value: 'Non-Permanent', color: '#316DB5'
                }
            ]
    };
    const dataLabelSettings = {

            labelPath: 'name',
            smartLabelMode: 'Trim'
    };
    const legendSettings = {

Run the project

Execute the following command to start the development server:

npm run dev

or

yarn run dev

The application will display a Maps component showing UN Security Council countries with color-coded memberships:

vue-3-js-maps

Sample: vue3-maps-getting-started.
