Getting Started with the Vue Gantt Chart Component in Vue 3

22 May 20269 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 Gantt Chart component 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

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

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: The name of the project can be specified directly. For this article, the project name is set as my-project.

? Project name: » my-project

2.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

3.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 ↗

4.Install dependencies and start the development server.

Install with npm and start now?: Yes

Since you selected Yes, the development server should start automatically. If you selected No, please follow these steps to set up and start the project manually:

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 Gantt Chart component as an example. To use the Vue Gantt Chart component in the project, the @syncfusion/ej2-vue-gantt package needs to be installed using the following command:

npm install @syncfusion/ej2-vue-gantt

yarn add @syncfusion/ej2-vue-gantt

Import Syncfusion^® CSS styles

In this article, Tailwind3 theme is applied using CSS styles, which are available in installed packages. The necessary Tailwind3 CSS styles for the Gantt Chart component and its dependents were imported into the <style> section of src/App.vue file.

Using local style

Import the needed css styles for the Gantt Chart component along with dependency styles in the <style> section of the src/App.vue file as follows.

<style>
@import "../node_modules/@syncfusion/ej2-base/styles/tailwind3.css";
@import "../node_modules/@syncfusion/ej2-gantt/styles/tailwind3.css";
@import "../node_modules/@syncfusion/ej2-grids/styles/tailwind3.css";
@import "../node_modules/@syncfusion/ej2-treegrid/styles/tailwind3.css";
@import "../node_modules/@syncfusion/ej2-layouts/styles/tailwind3.css";
@import "../node_modules/@syncfusion/ej2-popups/styles/tailwind3.css";
</style>

Note: When using features like editing, toolbar, filtering, or dialogs, you need to import additional component styles:

/* For editing, toolbar, and dialog features */
@import "../node_modules/@syncfusion/ej2-calendars/styles/tailwind3.css";
@import "../node_modules/@syncfusion/ej2-dropdowns/styles/tailwind3.css";
@import "../node_modules/@syncfusion/ej2-inputs/styles/tailwind3.css";
@import "../node_modules/@syncfusion/ej2-buttons/styles/tailwind3.css";
@import "../node_modules/@syncfusion/ej2-navigations/styles/tailwind3.css";
@import "../node_modules/@syncfusion/ej2-notifications/styles/tailwind3.css";

/* For rich text editor in dialog notes tab */
@import "../node_modules/@syncfusion/ej2-richtexteditor/styles/tailwind3.css";

Create sample data

Define a simple task list with hierarchical relationships. Each task must have a StartDate and either a Duration or EndDate to render properly.

const data = [
  { TaskID: 1, TaskName: 'Project initiation', StartDate: new Date('2024-04-01'), EndDate: new Date('2024-04-15') },
  { TaskID: 2, TaskName: 'Identify site location', StartDate: new Date('2024-04-01'), Duration: 4, Progress: 70, ParentID: 1 },
  { TaskID: 3, TaskName: 'Perform site survey', StartDate: new Date('2024-04-01'), Duration: 4, Progress: 50, ParentID: 1 },
  { TaskID: 4, TaskName: 'Soil testing', StartDate: new Date('2024-04-01'), Duration: 3, Progress: 40, ParentID: 1 },
  { TaskID: 5, TaskName: 'Project estimation', StartDate: new Date('2024-04-08'), EndDate: new Date('2024-04-18') },
  { TaskID: 6, TaskName: 'Develop floor plan', StartDate: new Date('2024-04-08'), Duration: 5, Progress: 30, ParentID: 5 },
  { TaskID: 7, TaskName: 'Estimate project cost', StartDate: new Date('2024-04-08'), Duration: 5, Progress: 20, ParentID: 5 }
]

Configure task fields

const taskFields = {
  id: 'TaskID',
  name: 'TaskName',
  startDate: 'StartDate',
  duration: 'Duration',
  progress: 'Progress',
  parentID: 'ParentID'
};

Field mapping reference

Property	Description	Required
`id`	Unique task identifier	Yes
`name`	Task display name	Yes
`startDate`	Task start date	Yes
`duration`	Task duration in days	Yes
`progress`	Task completion percentage (0-100)	No
`parentID`	Parent task ID for hierarchy	No

Render the Gantt component

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

First, import and register the Gantt component in the <script> section of the src/App.vue file. When using the Composition API, include the setup attribute in the <script> tag to enable it.

To display the Gantt Chart, bind your task data using the dataSource property and map the corresponding fields using the taskFields property.

App.vue
<template>
  <ejs-gantt 
    :dataSource="data"
    :taskFields="taskFields"
  >
  </ejs-gantt>
</template>

<script setup>
  // Import and register the Gantt component
  import { GanttComponent as EjsGantt} from '@syncfusion/ej2-vue-gantt';
  const data = [
    {TaskID: 1, TaskName: 'Project initiation', StartDate: new Date('2024-04-01'), EndDate: new Date('2024-04-15')},
    {TaskID: 2, TaskName: 'Identify site location', StartDate: new Date('2024-04-01'), Duration: 4, Progress: 70, ParentID: 1},
    {TaskID: 3, TaskName: 'Perform site survey', StartDate: new Date('2024-04-01'), Duration: 4, Progress: 50, ParentID: 1},
    {TaskID: 4, TaskName: 'Soil testing', StartDate: new Date('2024-04-01'), Duration: 3, Progress: 40, ParentID: 1},
    {TaskID: 5, TaskName: 'Project estimation', StartDate: new Date('2024-04-08'), EndDate: new Date('2024-04-18')},
    {TaskID: 6, TaskName: 'Develop floor plan', StartDate: new Date('2024-04-08'), Duration: 5, Progress: 30, ParentID: 5},
    {TaskID: 7, TaskName: 'Estimate project cost', StartDate: new Date('2024-04-08'), Duration: 5, Progress: 20, ParentID: 5}
  ];
  const taskFields = {
    id: 'TaskID',
    name: 'TaskName',
    startDate: 'StartDate',
    duration: 'Duration',
    progress: 'Progress',
    parentID: 'ParentID'
  };
</script>

<style>
@import "../node_modules/@syncfusion/ej2-base/styles/tailwind3.css";
@import "../node_modules/@syncfusion/ej2-gantt/styles/tailwind3.css";
@import "../node_modules/@syncfusion/ej2-grids/styles/tailwind3.css";
@import "../node_modules/@syncfusion/ej2-treegrid/styles/tailwind3.css";
@import "../node_modules/@syncfusion/ej2-layouts/styles/tailwind3.css";
@import "../node_modules/@syncfusion/ej2-popups/styles/tailwind3.css";
</style>

Running the application

Run the application using the following command.

npm run dev

Output

You will see a Gantt Chart with:

Task hierarchy with parent-child relationships
Timeline view showing task bars
Progress indicators on each task
Automatically calculated dates based on duration

The chart displays two parent tasks (“Project initiation” and “Project estimation”) with their subtasks shown in a tree structure. Task bars are rendered on the timeline, sized according to their duration and start dates.
