Installing Syncfusion ProgressButton 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-splitbuttons package to the application.

Copied to clipboard
npm install @syncfusion/ej2-angular-splitbuttons --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-splitbuttons@ngcc package to the application.

Copied to clipboard
npm install @syncfusion/ej2-angular-splitbuttons@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-splitbuttons:"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 ProgressButton module

Import ProgressButton module into Angular application(app.module.ts) from the package @syncfusion/ej2-angular-splitbuttons.

Copied to clipboard
import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

// Imported Syncfusion Progress button module from split buttons package
import { ProgressButtonModule } from '@syncfusion/ej2-angular-splitbuttons';

import { AppComponent }  from './app.component';

@NgModule({
  imports:      [ BrowserModule, ProgressButtonModule ], // Registering EJ2 ProgressButtonModule.
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

Adding Syncfusion ProgressButton component

Modify the template in app.component.ts file to render the ProgressButton component.

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

@Component({
selector: 'app-root',
template: `<!-- To render progress button. -->
           <button ejs-progressbutton content='Spin Left'></button>`
})

export class AppComponent {
}

Adding CSS reference

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

Copied to clipboard
@import '../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../node_modules/@syncfusion/ej2-buttons/styles/material.css';
@import '../node_modules/@syncfusion/ej2-popups/styles/material.css';
@import '../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css';

Running the application

Run the application in the browser using the following command:

           <button ejs-progressbutton content='Spin Left'></button>`
})

export class AppComponent {
}

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ProgressButtonModule } from '@syncfusion/ej2-angular-splitbuttons';
import { AppComponent } from './app.component';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,
        ProgressButtonModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

platformBrowserDynamic().bootstrapModule(AppModule);

ProgressButton supports different styles, types and sizes like Button. In addition, it also supports top and bottom icon positions.
