05 Oct 2022 / 3 minutes to read

This section explains you the steps required to create a simple Chip and demonstrate the basic usage of the Chip component in an Angular environment.

Setup Angular Environment

You can use Angular CLI to setup your Angular applications. To install Angular CLI use the following command.

Copied to clipboard
npm install -g @angular/cli

Create an Angular Application

Start a new Angular application using below Angular CLI command.

Copied to clipboard
ng new my-app
cd my-app

Installing Syncfusion Chips package

Syncfusion packages are distributed in npm as @syncfusion scoped packages. You can get all the Angular Syncfusion package from npm link.

Currently, Syncfusion provides two types of package structures for Angular components,

  1. Ivy library distribution package format
  2. Angular compatibility compiler(Angular’s legacy compilation and rendering pipeline) package.

Ivy library distribution package

Syncfusion Angular packages(>=20.2.36) has been moved to the Ivy distribution to support the Angular Ivy rendering engine and the package are compatible with Angular version 12 and above. To download the package use the below command.

Add @syncfusion/ej2-angular-buttons package to the application.

Copied to clipboard
npm install @syncfusion/ej2-angular-buttons --save

Angular compatibility compiled package(ngcc)

For Angular version below 12, you can use the legacy (ngcc) package of the Syncfusion Angular components. To download the ngcc package use the below.

Add @syncfusion/ej2-angular-buttons@ngcc package to the application.

Copied to clipboard
npm install @syncfusion/ej2-angular-buttons@ngcc --save

To mention the ngcc package in the package.json file, add the suffix -ngcc with the package version as below.

Copied to clipboard
@syncfusion/ej2-angular-buttons:"20.2.38-ngcc"

Note: If the ngcc tag is not specified while installing the package, the Ivy Library Package will be installed and this package will throw a warning.

Registering ChipList Module

Import ChipList module into Angular application(app.module.ts) from the package @syncfusion/ej2-angular-buttons [src/app/app.module.ts].

Copied to clipboard
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
// import the ChipListModule for the Chip component
import { ChipListModule } from '@syncfusion/ej2-angular-buttons';
import { AppComponent }  from './app.component';

@NgModule({
  //declaration of ej2-angular-buttons module into NgModule
  imports:      [ BrowserModule, ChipListModule ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

Adding CSS reference

Add Chip component CSS using the following code in [src/styles.css].

Copied to clipboard
@import "../node_modules/@syncfusion/ej2-angular-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-angular-buttons/styles/material.css";

Add Chip

Modify the template in [src/app/app.component.ts] file to render the Chip component. Add the Angular Chip by using <e-chip> child selector with text attribute inside of ChipList component selector <ejs-chiplist> in template section of the app.component.ts file.

Copied to clipboard
import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'my-app',
  // specifies the template string for the Chip component
  template: `<ejs-chiplist text="Janet Leverling"></ejs-chiplist>`
})
export class AppComponent {

}

Now, the basic chip is included in Angular CLI application.

Run the application

Use the following command to run the application in browser.

Copied to clipboard
ng serve --open

The output will appear as follows.

        BrowserModule,

    bootstrap: [AppComponent]
})
export class AppModule { }

import { AppModule } from './app.module';
