Getting Started with Vue UI Components with JavaScript and Composition API

21 Apr 20238 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 components using the Composition 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.

Prerequisites

System requirements for Syncfusion Vue UI components

Set up 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

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

2.Select Vue as the framework. It will creates a Vue 3 project.

? Select a framework: » - Use arrow-keys. Return to submit.
Vanilla
> Vue
  React
  Preact
  Lit
  Svelte
  Others

3.Choose JavaScript as 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 ↗

4.Upon completing the aforementioned steps to create the my-project, run the following command to install its dependencies:

cd my-project
npm install

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 article uses the Vue Grid component as an example. To use the Vue Grid component in the project, the @syncfusion/ej2-vue-grids package needs to be installed using the following command:

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

yarn add @syncfusion/ej2-vue-grids

Import Syncfusion CSS styles

You can import themes for the Syncfusion Vue component in various ways, such as using CSS or SASS styles from npm packages, CDN, CRG and Theme Studio. Refer to themes topic to know more about built-in themes and different ways to refer to themes in a Vue project.

In this article, Material theme is applied using CSS styles, which are available in installed packages. The necessary Material CSS styles for the Grid component and its dependents were imported into the <style> section of src/App.vue file.

<style>
  @import "../node_modules/@syncfusion/ej2-base/styles/material.css";
  @import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";
  @import "../node_modules/@syncfusion/ej2-calendars/styles/material.css";
  @import "../node_modules/@syncfusion/ej2-dropdowns/styles/material.css";
  @import "../node_modules/@syncfusion/ej2-inputs/styles/material.css";
  @import "../node_modules/@syncfusion/ej2-navigations/styles/material.css";
  @import "../node_modules/@syncfusion/ej2-popups/styles/material.css";
  @import "../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css";
  @import "../node_modules/@syncfusion/ej2-vue-grids/styles/material.css";
</style>

The order of importing CSS styles should be in line with its dependency graph.

Add Syncfusion Vue component

Follow the below steps to add the Vue Grid component using Composition API:

1.First, add the setup attribute to the script tag to indicate that Vue will be using the Composition API. And import the Grid component in the script section of the src/App.vue file.

<script setup>
  import { GridComponent as EjsGrid, ColumnsDirective as EColumns, ColumnDirective as EColumn } from '@syncfusion/ej2-vue-grids';
</script>

2.In the template section, define the Grid component with the dataSource property and column definitions.

<template>
  <ejs-grid :dataSource='data'>
    <e-columns>
      <e-column field='OrderID' width='100' textAlign="Right"></e-column>
      <e-column field='CustomerID' width='100'></e-column>
      <e-column field='EmployeeID' width='100' textAlign="Right"></e-column>
      <e-column field='Freight' width='100' format="C2" textAlign="Right"></e-column>
      <e-column field='ShipCountry' width='100'></e-column>
    </e-columns>
  </ejs-grid>
</template>

3.Declare the values for the dataSource property in the script section.

<script setup>
const data = [
  {
    OrderID: 10248, CustomerID: 'VINET', EmployeeID: 5, OrderDate: new Date(8364186e5),
    ShipName: 'Vins et alcools Chevalier', ShipCity: 'Reims', ShipAddress: '59 rue de l Abbaye',
    ShipRegion: 'CJ', ShipPostalCode: '51100', ShipCountry: 'France', Freight: 32.38, Verified: !0
  },
  {
    OrderID: 10249, CustomerID: 'TOMSP', EmployeeID: 6, OrderDate: new Date(836505e6),
    ShipName: 'Toms Spezialitäten', ShipCity: 'Münster', ShipAddress: 'Luisenstr. 48',
    ShipRegion: 'CJ', ShipPostalCode: '44087', ShipCountry: 'Germany', Freight: 11.61, Verified: !1
  },
  {
    OrderID: 10250, CustomerID: 'HANAR', EmployeeID: 4, OrderDate: new Date(8367642e5),
    ShipName: 'Hanari Carnes', ShipCity: 'Rio de Janeiro', ShipAddress: 'Rua do Paço, 67',
    ShipRegion: 'RJ', ShipPostalCode: '05454-876', ShipCountry: 'Brazil', Freight: 65.83, Verified: !0
  }
];
</script>

Here is the summarized code for the above steps in the src/App.vue file:

<template>
  <ejs-grid :dataSource='data'>
    <e-columns>
      <e-column field='OrderID' width='100' textAlign="Right"></e-column>
      <e-column field='CustomerID' width='100'></e-column>
      <e-column field='EmployeeID' width='100' textAlign="Right"></e-column>
      <e-column field='Freight' width='100' format="C2" textAlign="Right"></e-column>
      <e-column field='ShipCountry' width='100'></e-column>
    </e-columns>
  </ejs-grid>
</template>

<script setup>
import { GridComponent as EjsGrid, ColumnsDirective as EColumns, ColumnDirective as EColumn } from '@syncfusion/ej2-vue-grids';

const data = [
  {
    OrderID: 10248, CustomerID: 'VINET', EmployeeID: 5, OrderDate: new Date(8364186e5),
    ShipName: 'Vins et alcools Chevalier', ShipCity: 'Reims', ShipAddress: '59 rue de l Abbaye',
    ShipRegion: 'CJ', ShipPostalCode: '51100', ShipCountry: 'France', Freight: 32.38, Verified: !0
  },
  {
    OrderID: 10249, CustomerID: 'TOMSP', EmployeeID: 6, OrderDate: new Date(836505e6),
    ShipName: 'Toms Spezialitäten', ShipCity: 'Münster', ShipAddress: 'Luisenstr. 48',
    ShipRegion: 'CJ', ShipPostalCode: '44087', ShipCountry: 'Germany', Freight: 11.61, Verified: !1
  },
  {
    OrderID: 10250, CustomerID: 'HANAR', EmployeeID: 4, OrderDate: new Date(8367642e5),
    ShipName: 'Hanari Carnes', ShipCity: 'Rio de Janeiro', ShipAddress: 'Rua do Paço, 67',
    ShipRegion: 'RJ', ShipPostalCode: '05454-876', ShipCountry: 'Brazil', Freight: 65.83, Verified: !0
  }
];
</script>
