11 Jul 20245 minutes to read

This section explains how to create a simple Button and demonstrate the basic usage of the Button module in an Angular environment.

Dependencies

The list of dependencies required to use the Button module in your application is given below:

|-- @syncfusion/ej2-angular-buttons
    |-- @syncfusion/ej2-angular-base
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-buttons

Setup Angular environment

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

npm install -g @angular/cli

Create an Angular application

Start a new Angular application using below Angular CLI command.

ng new my-app
cd my-app

Installing Syncfusion Button 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.

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.

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.

@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.

Adding Syncfusion Button component

Modify the template in app.component.ts file to render the Button module.

import { ButtonModule } from '@syncfusion/ej2-angular-buttons'
import { Component } from '@angular/core';

@Component({
imports: [
      ButtonModule
    ],
    standalone: true,
    selector: 'app-root',
    template: `<div class="e-section-control">
                <!-- To render Button. -->
               <button ejs-button>Button</button></div>`
})

export class AppComponent { }

Adding CSS reference

Add Button component’s styles as given below in style.css.

@import '../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../node_modules/@syncfusion/ej2-buttons/styles/material.css';

Running the application

Run the application in the browser using the following command:

ng serve

The following example shows a basic Button component.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ButtonModule } from '@syncfusion/ej2-angular-buttons'
import { enableRipple } from '@syncfusion/ej2-base'



import { Component } from '@angular/core';

@Component({
imports: [
        
        ButtonModule
    ],


standalone: true,
    selector: 'app-root',
    template: `<div class="e-section-control">
                <!-- To render Button. -->
               <button ejs-button>Button</button></div>`
})

export class AppComponent { }

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Change Button type

To change the default Button to flat Button, set the cssClass property with e-flat and text content of the Button is set using content property.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ButtonModule } from '@syncfusion/ej2-angular-buttons'
import { enableRipple } from '@syncfusion/ej2-base'



import { Component } from '@angular/core';

@Component({
imports: [
        
        ButtonModule
    ],


standalone: true,
    selector: 'app-root',
    template: `<div class="e-section-control">
                <!-- To change the Button type. -->
               <button ejs-button cssClass="e-flat" content="Button"></button></div>`
})

export class AppComponent { }

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
