Getting Started with Vue 3 in Vue Gantt component

08 Oct 2021 / 24 minutes to read

This section explains how to use Gantt component in Vue 3 application.

Prerequisites

  • vue : 3+
  • node : 10.15+
  • vue-class-component : 8.0.0-rc.1

Creating Vue application using Vue CLI

The easiest way to create a Vue application is to use the Vue CLI. Vue CLI versions above 4.5.0 are mandatory for creating applications using Vue 3. Use the following command to uninstall older versions of the Vue CLI.

Copied to clipboard
npm uninstall vue-cli -g

Use the following commands to install the latest version of Vue CLI.

Copied to clipboard
npm install -g @vue/cli
npm install -g @vue/cli-init

Create a new project using the command below.

Copied to clipboard
vue create quickstart

Initiating a new project prompts us to choose the type of project to be used for the current application. Select the option Default (Vue 3 Preview) from the menu.

Reference

Adding Syncfusion Gantt package in the application

Syncfusion Vue packages are maintained in the npmjs.com registry.

To install Gantt component, use the following command

Copied to clipboard
npm install @syncfusion/ej2-vue-gantt --save

The —save will instruct NPM to include the Gantt package inside of the dependencies section of the package.json.

Adding CSS reference for Syncfusion Vue Gantt component

The Gantt has different themes. They are:

  • Material
  • Fabric
  • Bootstrap
  • High Contrast

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

Copied to clipboard
<script>
<!-- Material theme used for this sample -->
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";
import "../node_modules/@syncfusion/ej2-vue-gantt/styles/material.css";
</script>

Note: Gantt component use other Syncfusion components too, the dependent component’s CSS references need to be added for using all the Gantt functionalities.

Adding Syncfusion Vue Gantt component in the application

You have completed all the necessary configurations needed for rendering the Syncfusion Vue component. Now, you are going to add the Gantt component using following steps.

  1. Import the Gantt component in the <script> section of the src/App.vue file.
Copied to clipboard
   <script>
   import { GanttComponent, ColumnsDirective, ColumnDirective } from '@syncfusion/ej2-vue-gantt';
   </script>
  
  1. Register the Gantt component along with the required child directives which are used in this example. Find the list of child directives and the tag names that can be used in the Gantt component in the following table.

    Directive Name Tag Name
    ColumnsDirective e-columns
    ColumnDirective e-column
Copied to clipboard
   import { GanttComponent, ColumnsDirective, ColumnDirective } from '@syncfusion/ej2-vue-gantt';
 //Component registeration
   export default {
   name: "App",
   components: {
     'ejs-gantt' : GanttComponent,
     'e-columns' : ColumnsDirective,
     'e-column' : ColumnDirective
    }
   }

In the above code snippet, you have registered Gantt and the column directives. Column directives are used to define the column definition for the Gantt component.

  1. Add the Vue Gantt by using <ejs-gantt> selector in <template> section.
Copied to clipboard
   <template>
   <ejs-gantt :dataSource='data' :treeColumnIndex='1' child='subtasks'>
       <e-columns>
           <e-column field='taskID' headerText='Task ID' textAlign='Right' width=70></e-column>
           <e-column field='taskName' headerText='Task Name' textAlign='Left' width=200></e-column>
           <e-column field='startDate' headerText='Start Date' textAlign='Right' format='yMd' width=90></e-column>
           <e-column field='duration' headerText='Duration' textAlign='Right' width=80></e-column>
      </e-columns>
   </ejs-gantt>
   </template>
  

In the above code example for Gantt component definition, with dataSource property binding and columns definitions. In the dataSource property binding, we represent the hierarchical data binding in which child property denotes the hierarchy relationship; whereas in self-referencing data binding and parentId denotes the hierarchy relationship.

  1. Declare the bound properties in the script section. Declare the collection data which is bound for the dataSource property.

   data() {
 return {
   data:  [{
        TaskID: 1,
        TaskName: 'Planning',
        StartDate: new Date('02/03/2017'),
        EndDate: new Date('02/07/2017'),
        Progress: 100,
        Duration: 5,
        subtasks: [
            { TaskID: 2, TaskName: 'Plan timeline', StartDate: new Date('02/03/2017'), EndDate: new Date('02/07/2017'), Duration: 5, Progress: 100,},
            { TaskID: 3, TaskName: 'Plan budget', StartDate: new Date('02/03/2017'), EndDate: new Date('02/07/2017'), Duration: 5, Progress: 100, },
            { TaskID: 4, TaskName: 'Allocate resources', StartDate: new Date('02/03/2017'), EndDate: new Date('02/07/2017'), Duration: 5, Progress: 100, },
            { TaskID: 5, TaskName: 'Planning complete', StartDate: new Date('02/07/2017'), EndDate: new Date('02/07/2017'), Duration: 0, Progress: 0, }
        ]
    },
    {
        TaskID: 6,
        TaskName: 'Design',
        StartDate: new Date('02/10/2017'),
        EndDate: new Date('02/14/2017'),
        Duration: 3,
        Progress: 86,
        subtasks: [
            { TaskID: 7, TaskName: 'Software Specification', StartDate: new Date('02/10/2017'), EndDate: new Date('02/12/2017'), Duration: 3, Progress: 60, },
            { TaskID: 8, TaskName: 'Develop prototype', StartDate: new Date('02/10/2017'), EndDate: new Date('02/12/2017'), duration: 3, Progress: 100,},
            { TaskID: 9, TaskName: 'Get approval from customer', startDate: new Date('02/13/2017'), EndDate: new Date('02/14/2017'), Duration: 2, Progress: 100, },

        ]
    }]
 };
   }
  1. To create Gantt with additional features, inject the required modules. The following modules are used to extend Gantt’s basic functionality.
  2. Edit : Inject this module to use the editing feature.
  3. Filter : Inject this module to use the filtering feature.
  4. Sort : Inject this module to use the sorting feature.
  5. Selection : Inject this module to use the selection feature.
  6. Toolbar : Inject this module to use the toolbar items.
  7. DayMarkers : Inject this module to highlight the days. Register the required array of modules under the key gantt in the provide section.

    Additional feature modules are available here

Binding Gantt with data

Bind data with the Gantt component by using the dataSource property. It accepts an array of JavaScript object or the DataManager instance.

        },
  };
  },
  provide: {
  gantt: [ Edit, Selection, Toolbar, DayMarkers ]
  }
};
</script>

Enabling editing

The editing feature enables you to edit the tasks in Gantt component. It can be enabled by using the editSettings.allowEditing and editSettings.allowTaskbarEditing properties.

To use Editing, inject the Edit module in the provide section.

The following editing options are available to update the tasks in Gantt:

  • Cell
  • Dialog
  • Taskbar
  • Connector line

Cell editing

Modify the task details through cell editing by setting the edit mode property as Auto. To enable edit support Edit module should be injected in Gantt. If Edit module is not injected, you cannot do any editing action in Gantt.

Enabling predecessors or task relationships

Predecessor or task dependency in the Gantt component is used to depict the relationship between the tasks.

Start to Start (SS) : You cannot start a task until the dependent task starts. Start to Finish (SF) : You cannot finish a task until the dependent task finishes. Finish to Start (FS) : You cannot start a task until the dependent task completes. Finish to Finish (FF) : You cannot finish a task until the dependent task completes.

You can show the relationship in tasks, by using the dependency property as shown in the following code example:
