Get Started with Vue CLI

You can use Vue CLI to setup your vue applications. To install Vue CLI use the following command.

npm install -g @vue/cli
npm install -g @vue/cli-init

Start a new project using below Vue CLI command.

vue init webpack-simple quickstart

cd quickstart
npm install

Adding Syncfusion packages

All the available Essential JS 2 packages are published in npmjs.com registry. You can choose the component that you want to install. For this application, we are going to use Circulargauge component.

To install Circulargauge component, use the following command

npm install @syncfusion/ej2-vue-circulargauge –save

Registering Vue Component

For Registering Vue Component two ways are available. They are as follows.

  • Vue.use()
  • Vue.component()

Using Vue.use()

Import the Component Plugin from the EJ2 Vue Package and register the same using Vue.use() with Component Plugin as its argument.

Refer the code snippet given below.

import { CircularGaugePlugin } from '@syncfuion/ej2-vue-circulargauge';

Vue.use(CircularGaugePlugin);

By Registering Component Plugin in Vue, all child directives are also globally registered.

Using Vue.component()

Import the Component and Component Plugin from EJ2 Vue Package, register the same using the Vue.component() with name of Component from ComponentPlugin and the EJ2 Vue Component as its arguments.

Refer the code snippet given below.

import { CircularGaugeComponent, CircularGaugePlugin } from '@syncfusion/ej2-vue-circulargauge';

Vue.component(CircularGaugePlugin.name, CircularGaugeComponent);

Note: By using Vue.component(), only the EJ2 Vue Component is registered. Child directives needs to be registered separately.

Adding CSS Reference

Add Circulargauge component’s styles as given below in <style> section of the App.vue file.

<style>
@import "../../node_modules/@syncfusion/ej2-vue-circulargauge/styles/material.css";
</style>

Run the application

Now use the npm run dev command to run the application in the browser.

npm run dev
