Installation and configuration
-
To setup basic
Angular
sample use the following commands.git clone https://github.com/angular/quickstart.git quickstart cd quickstart npm install
For more information, refer to Angular sample setup.
-
Install Syncfusion notifications package using below command.
npm install @syncfusion/ej2-notifications --save
-
The Badge component CSS files are available in the
ej2-notifications
package folder. This can be referenced in your application using the following code.[src/styles.css]
@import '../node_modules/@syncfusion/ej2-base/styles/material.css'; @import '../node_modules/@syncfusion/ej2-notifications/styles/material.css';
Installing Syncfusion notifications 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,
- Ivy library distribution package format
- 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-notifications
package to the application.
npm install @syncfusion/ej2-angular-notifications --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-notifications@ngcc
package to the application.
npm install @syncfusion/ej2-angular-notifications@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-notifications:"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.
Add badge into application
Modify the template
in app.component.ts
file to render the Badge component.
[src/app/app.component.ts]
import { Component } from '@angular/core';
@Component({
selector: 'my-app',
template: `<div id='element'><h1>Badge Component <span class="e-badge">New</span></h1></div>`
})
export class AppComponent {}
Run the application
Run the application in the browser using the following command.
npm start
The following example shows a basic badge component.
import { Component } from '@angular/core';
@Component({
selector: 'my-app',
template: `<div id='element'><h1>Badge Component <span class="e-badge">New</span></h1></div>`
})
export class AppComponent {}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
/**
* Module
*/
@NgModule({
imports: [
BrowserModule,
],
declarations: [AppComponent],
bootstrap: [AppComponent]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
