14 Nov 20226 minutes to read

This section explains you the steps required to create a progressbar and demonstrate the basic usage of the progressbar control.

Dependencies

Below is the list of minimum dependencies required to use the progressbar component.

    |-- @syncfusion/ej2-angular-progressbar
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-data: "*"
    |-- @syncfusion/ej2-svg-base

Installation and Configuration

*You can use Angular CLI to setup your angular applications.

npm install -g @angular/cli

For more information, refer to Angular sample setup

• Install progressbar packages using below command.

npm install @syncfusion/ej2-angular-progressbar --save

The above package installs progressbar dependencies
which are required to render the component in Angular environment

• Syncfusion ej2-angular-progressbar
  packages needs to be mapped in systemjs.config.js configuration file.

/**
 * System configuration for Angular samples
 * Adjust as necessary for your application needs.
 */
(function (global) {
  System.config({
    paths: {
      // paths serve as alias
      'npm:': 'node_modules/',
      "syncfusion:": "node_modules/@syncfusion/", // syncfusion alias

    },
    // map tells the System loader where to look for things
    map: {
      // our app is within the app folder
      'app': 'app',

      // angular bundles
      '@angular/core': 'npm:@angular/core/bundles/core.umd.js',
      '@angular/common': 'npm:@angular/common/bundles/common.umd.js',
      '@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
      '@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
      '@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
      '@angular/http': 'npm:@angular/http/bundles/http.umd.js',
      '@angular/router': 'npm:@angular/router/bundles/router.umd.js',
      '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',

      // syncfusion bundles
        "@syncfusion/ej2-base": "syncfusion:ej2-base/dist/ej2-base.umd.min.js",
        "@syncfusion/ej2-data": "syncfusion:ej2-data/dist/ej2-data.umd.min.js",
        "@syncfusion/ej2-progressbar": "syncfusion:ej2-progressbar/dist/ej2-progressbar.umd.min.js",
        "@syncfusion/ej2-angular-progressbar": "syncfusion:ej2-angular-progressbar/dist/ej2-angular-progressbar.umd.min.js",


      // other libraries
      'rxjs':                      'npm:rxjs',
      'angular-in-memory-web-api': 'npm:angular-in-memory-web-api/bundles/in-memory-web-api.umd.js'
    },
    // packages tells the System loader how to load when no filename and/or no extension
    packages: {
      app: {
        defaultExtension: 'js',
        meta: {
          './*.js': {
            loader: 'systemjs-angular-loader.js'
          }
        }
      },
      rxjs: {
        defaultExtension: 'js'
      }
    }
  });
})(this);

• Import Chart module into Angular application(app.module.ts) from the package @syncfusion/ej2-angular-progressbar

[src/app/app.module.ts].

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
// import the ProgressBarModule for the Chart component
import { ProgressBarModule } from '@syncfusion/ej2-angular-progressbar';
import { AppComponent }  from './app.component';

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

• Modify the template in app.component.ts file to render the ej2-ng-progressbar component

[src/app/app.component.ts].

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

@Component({
  selector: 'app-container',
  // specifies the template string for the Charts component
  template: `<ejs-progressbar id='percentage'></ejs-progressbar>`,
  encapsulation: ViewEncapsulation.None
})
export class AppComponent  { }

Now use the app-container in the index.html instead of default one.

<app-container></app-container>

• Now run the application in the browser using the below command.

npm start

The below example shows a basic Progressbar.

app.component.ts

import { Component } from '@angular/core';
import { AnimationModel } from '@syncfusion/ej2-progressbar';

@Component({
    selector: 'my-app',
    // specifies the template string for the Progressbar component
    template: `<ejs-progressbar id='percentage'  type='Linear' height='60' [value]='value' [animation]='animation'> </ejs-progressbar>`
})

export class AppComponent {
   public animation: AnimationModel = { enable: true, duration: 2000, delay: 0 };
   public value: number = 40;
}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { ProgressBarModule } from '@syncfusion/ej2-angular-progressbar';
/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, ProgressBarModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
})
export class AppModule { }

main.ts

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

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
