Getting started with Vue Gantt component

This section explains the steps required to create a Gantt and demonstrates the basic usage of the Gantt component.

Dependencies

Following is the list of dependencies to use the Gantt with all features:

|-- @syncfusion/ej2-gantt
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-buttons
    |-- @syncfusion/ej2-calendars
    |-- @syncfusion/ej2-data
    |-- @syncfusion/ej2-dropdowns
    |-- @syncfusion/ej2-grids
    |-- @syncfusion/ej2-inputs
    |-- @syncfusion/ej2-layouts
    |-- @syncfusion/ej2-lists
    |-- @syncfusion/ej2-navigations
    |-- @syncfusion/ej2-popups
    |-- @syncfusion/ej2-richtexteditor
    |-- @syncfusion/ej2-treegrid

Installation and configuration

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 following 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 Gantt component.

To install Gantt component, use the following command:

npm install @syncfusion/ej2-vue-gantt –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 following code snippet:

import { GanttPlugin } from '@syncfuion/ej2-vue-gantt';

Vue.use(GanttPlugin);

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 following code snippet:

import { GanttComponent, GanttPlugin } from '@syncfusion/ej2-vue-gantt';

Vue.component(GanttPlugin.name, GanttComponent);

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

Initialize Gantt component

Add the EJ2 Vue Gantt using <ejs-gantt> to the <template> section of the App.vue file in src directory, the content attribute of the Gantt component is provided as name in data option in the <script> section.

<template>
    <div id="app">
    <ejs-gantt></ejs-gantt>
  </div>
</template>
<script>
import Vue from 'vue';
import { GanttPlugin } from '@syncfusion/ej2-vue-gantt';

Vue.use(GanttPlugin);
export default Vue.extend ({});
</script>

Adding CSS reference

Add Gantt component’s styles as following code under <style> section of the 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-lists/styles/material.css';
@import '../node_modules/@syncfusion/ej2-layouts/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-grids/styles/material.css';
@import '../node_modules/@syncfusion/ej2-richtexteditor/styles/material.css';
@import '../node_modules/@syncfusion/ej2-treegrid/styles/material.css';
@import "../node_modules/@syncfusion/ej2-vue-gantt/styles/material.css";
</style>

Note: Use above CSS styles in <style> </style> tag for rendering all code snippets.

Module injection

The Gantt components was segregated into individual feature-wise modules. To use its feature, you need to inject its feature service in the AppModule. Find the relevant feature modules and descriptions as follows:

  • Edit : Inject this module to use the editing feature.
  • Filter : Inject this module to use the filtering feature.
  • Sort : Inject this module to use the sorting feature.
  • Selection : Inject this module to use the selection feature.
  • Toolbar : Inject this module to use the toolbar items.
  • DayMarkers : Inject this module to highlight the days.

Now, import the above-mentioned modules from the Gantt package and inject them using providelike following code:

import Vue from "vue";
import { GanttPlugin , Edit, Filter, Sort } from "@syncfusion/ej2-vue-gantt";

Vue.use(GanttPlugin);

export default {
  provide: {
    gantt: [ Edit, Filter, Sort ]
  }
};

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.

Defining timeline

The Gantt has an option to define timeline using timelineSettings property with various options. Using this property we can customize the Gantt timeline.

  }
};
</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.

Note: When the edit mode is set to Auto, you can change the cells to editable mode by double-clicking anywhere at the TreeGrid and edit the task details in the edit dialog by double-clicking anywhere at the chart.

Dialog editing

Modify the task details through dialog by setting edit mode property as Dialog.

Taskbar editing

Modify the task details through user interaction such as resizing and dragging the taskbar by enabling the allowTaskbarEditing property.

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:

Assigning resources

You can display and assign the resource for each task in the Gantt component. Create a collection of object, which contains ID and name of the resource and assign it to the resources property. Map the resource ID and name to resourceIDMapping and resourceNameMapping properties, respectively.

Enable filtering

The filtering feature enables you to view reduced amount of records based on filter criteria. Gantt provides support for menu filtering support for each columns. It can be enabled by setting the allowFiltering property to true along with injecting the Filter module module as shown in the following code example. Filtering feature can also be customized using the filterSettings property.

To use Filtering, inject the Filter module in the provide section.

Enable sorting

The sorting feature enables you to order the records. It can be enabled by setting the allowSorting property to true. Provide the Sort module as follows. If Sort module is not provided, you cannot sort when a header is clicked. The sorting feature can be customized using the sortSettings(../api/gantt/sortSettings/) property.

To use Sorting, inject the Sort module in the provide section.
