How to get started easily with Syncfusion Angular 11 Gantt Chart?
The Essential JS2 Angular Gantt control is designed to visualize and edit the project schedule and track the project progress. It helps to organize and schedule the projects and you can update the project schedule through interactions like editing, dragging and resizing. In this knowledge base we are going to provide details about create and integrate an Angular 11 Gantt chart Application with a minimal code configuration.
Prerequisites
Before start, we need following items to create Angular Gantt in Angular 11 application
- Node.js (latest version)
- Angular 11
- Angular CLI
- Typescript 4+
- Visual Studio Code for Editor
Installation and application creation
- Install Angular cli 11 using following command.
npm install -g @angular/cli@11.2.3
If you would like to follow and run the application in Angular 8 or Angular 7 or Angular 6 or Angular 5 or Angular 4, you need to replace the CLI command version number with corresponding angular version number.
npm install -g @angular/cli@<CLI VERSION>
- Create an Angular 11 application using Angular cli.
ng new angular11-app
cd angular11-app
- Install the ej2-angular-gantt package through the npm install command.
npm install @syncfusion/ej2-angular-gantt --save
- Serve the Angular 11 application using following command
ng serve --open
Listen the application in localhost:4200. Your application will serve in browser. Refer the below example screenshot for Angular 11 version.
Adding Angular 11 Gantt chart
You can add the Angular 11 Gantt component by using `ejs-gantt` directive and the attributes used within this tag allows you to define other Gantt functionalities.
- Import the GanttModule in app.module.ts file from the ej2-angular-gantt-package.
- The next step in Angular Gantt Chart creation is to import and inject the other required modules within providers section of app.module.ts.
[app.module.ts]
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { GanttModule } from '@syncfusion/ej2-angular-gantt';
import { AppComponent } from './app.component';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
GanttModule
],
bootstrap: [AppComponent]
})
export class AppModule { }
- You should refer the CSS file for Angular Gantt in styles.css.
@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-lists/styles/material.css';
@import '../node_modules/@syncfusion/ej2-layouts/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-richtexteditor/styles/material.css';
@import '../node_modules/@syncfusion/ej2-grids/styles/material.css';
@import '../node_modules/@syncfusion/ej2-treegrid/styles/material.css';
@import '../node_modules/@syncfusion/ej2-gantt/styles/material.css';
- Add the Angular Gantt component in app.component.html.
<ejs-gantt></ejs-gantt>
- Now, define the row data for this Gantt in app.component.ts. Here, the JSON data is used for the Gantt.
export class AppComponent implements OnInit {
public data: Object[];
public taskfield: Object;
ngOnInit() {
this.data = [{
TaskID: 1,
TaskName: 'Product Concept',
StartDate: new Date('04/02/2019'),
EndDate: new Date('04/21/2019'),
subtasks: [{
TaskID: 2,
TaskName: 'Defining the product and its usage',
StartDate: new Date('04/02/2019'),
Duration: 5,
Progress: 30
},
]
}, ];
this.taskfield = {
id: 'TaskID',
name: 'TaskName',
startDate: 'StartDate',
endDate: 'EndDate',
child: 'subtasks'
};
}
}
- After defining the data source for Gantt, define the data source and task fields in app.component.html file.
<ejs-gantt id="GanttSample"
[dataSource]="data"
height= "450px"
width="800px"
[taskFields]= "taskfield">
</ejs-gantt>
- Now serve the application using following command.
ng serve --open
Once all the files are compiled successfully. It will serve the site at localhost:4200
The following screenshot illustrates this.
Enabling features
Till now we have studied how to integrate Gantt control in Angular 11 application. This section describes how to inject Gantt services and enable its features. Before enable Gantt features, we need to define their services in app.module.ts.
import { GanttModule, ResizeService, SortService, FilterService, SelectionService, ReorderService,
EditService, DayMarkersService, ToolbarService } from '@syncfusion/ej2-angular-gantt';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
GanttModule
],
providers: [ ResizeService, SortService, FilterService, SelectionService, ReorderService,
EditService, DayMarkersService, ToolbarService],
bootstrap: [AppComponent]
})
export class AppModule { }
Filtering
By declaring FilterService in app.module.ts, you can use filtering functionalities in Gantt. To enable filter, we need to define allowFiltering as true.
<ejs-gantt id='GanttSample'
[dataSource]='data'
height= '450px'
allowFiltering = 'true'
[taskFields]= 'taskfield'>
</ejs-gantt>
After enabling the, filter menu UI will be obtained as follows.
Event Markers
By declaring DayMarkersService in app.module.ts, You can mark special events in project. As this is an object array you can mark more than one events in the Gantt chart.
<ejs-gantt id='GanttSample'
[dataSource]='data'
height= '450px'
allowFiltering = 'true'
[eventMarkers] = 'eventMarkers'
[taskFields]= 'taskfield'>
</ejs-gantt>
TS
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
public data: Object[];
public eventMarkers: any;
ngOnInit() {
this.eventMarkers = [{
day: '04/04/2019',
label: 'Research phase'
}];
}
}
After defining day markers. UI will be obtained as follows.
