We will learn the implementation of toaster notification in Angular 10/11/12.
In addition to this, we will also get to know how to use toaster notification in Angular 11/12 using ngx-toastr npm package for toaster notification. Also, two npm packages ngx-toastr and @angular/animations that provide to use success, error, warning and info alert messages.
Learn to use Toaster Notification in Angular 11/12
We simply need to follow the given steps for implementing the Toaster Notification in Angular 12 app:
Step 1 is to Create the New Angular App
Step 2 is to Install the Toaster Notification
Step 3 is to Add Code on App.Module.ts File
Step 4 is to Add Code on View File
Step 5 is to Add Code On app.Component ts File
Step 6 is to Create Service for Notification
Step 7 is to Start the Angular App
Now, let’s learn in detail
Step 1- Creating the New Angular App
First of all, open your terminal and execute the given command on it to install an angular app:
ng new toaster-notification-app
Step 2 : Installing the Toatser Notification
Next, just install the npm package called npm install ngx-toastr -save for implementing the toaster notification in an Angular app. Further, we can install the packages by executing the following commands on the terminal
npm install ngx-toastr --save
npm install @angular/animations --save
Thereafter, we open the angular.json file and update the following code into it:
.....
"styles": [
"node_modules/ngx-toastr/toastr.css",
"src/styles.css"
],
.....
Step 3: Adding Code on App.Module.ts File
Afterwards, we visit src/app directory and open app.module.ts file. Thereafter, we also add the following lines into app.module.ts file:
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { ToastrModule } from 'ngx-toastr';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
BrowserAnimationsModule,
ToastrModule.forRoot()
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
Step 4: Adding the Code on View File
In next step, we create the owl carousel in the Angular 11 app. Then, we visit src/app/ and app.component.html and update the following code into it:
<h1>Angular 11 Toastr Notifications Example - Thecodemon.com</h1>
<button (click)="showToasterSuccess()">
Success Toaster
</button>
<button (click)="showToasterError()">
Error Toaster
</button>
<button (click)="showToasterInfo()">
Info Toaster
</button>
<button (click)="showToasterWarning()">
Warning Toaster
</button>
Step 5: Adding Code On app.Component ts File
Now, follow this step in which we visit the src/app directory and open app.component.ts. After this, we add the following code into component.ts file:
import { Component } from '@angular/core';
import { NotificationService } from './notification.service'
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'toaster-not';
constructor(private notifyService : NotificationService) { }
showToasterSuccess(){
this.notifyService.showSuccess("Data shown successfully !!", "ItSolutionStuff.com")
}
showToasterError(){
this.notifyService.showError("Something is wrong", "ItSolutionStuff.com")
}
showToasterInfo(){
this.notifyService.showInfo("This is info", "ItSolutionStuff.com")
}
showToasterWarning(){
this.notifyService.showWarning("This is warning", "ItSolutionStuff.com")
}
}
Step 6: Create Service for Notification
In this step, we open the terminal and execute the following command into it:
ng generate service notification
Now, we visit the src/app directory and open notification.service.ts. After this, we add the following code into notification.service.ts file:
import { Injectable } from '@angular/core';
import { ToastrService } from 'ngx-toastr';
@Injectable({
providedIn: 'root'
})
export class NotificationService {
constructor(private toastr: ToastrService) { }
showSuccess(message, title){
this.toastr.success(message, title)
}
showError(message, title){
this.toastr.error(message, title)
}
showInfo(message, title){
this.toastr.info(message, title)
}
showWarning(message, title){
this.toastr.warning(message, title)
}
}
Starting the Angular App
Lastly, we reach the final step of implementation where we execute the following command executed on the terminal to start angular owl carousel app:
ng serve
Conclusion
Finally, we reach the end of explaining implementation of Toaster Notification in Angular 12 app. Hope you have well understood the concept.
