I will explain step by step tutorial how to create angular 8 toaster notifications. it's simple example of how to use toaster in angular 8. I’m going to show you about toaster alert in angular 8. Here you will learn toaster alert angular 8.

We will use ngx-toastr npm package for toastr notification in angular 8 application. we need to install two npm packages ngx-toastr and @angular/animations that provide to use success, error, warning and info alert messages.

I will give you very simple example and step by step so you can easily implement toaster notification in your angular 8 application. you can see bellow preview for alert too.

Step 1: Create New App

You can easily create your angular 8 app using bellow command:

ng new my-new-app

Step 2: Install Toastr

In this step, we will install ngx-toastr and @angular/animations npm packages. so let's run both command as like bellow:

npm install ngx-toastr --save

npm install @angular/animations --save

Now, we need to include toastr css like "node_modules/ngx-toastr/toastr.css", so let's add it on angular.json file.

angular.json

.....

"styles": [

"node_modules/ngx-toastr/toastr.css",

"src/styles.css"

],

.....

Step 3: Import Module

In this step, we need to import ToastrModule and BrowserAnimationsModule to app.module.ts file. so let's import it as like bellow:

src/app/app.module.ts

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: Create Service for Notification

Here, we will create separate notification for Toastr. so you can use showSuccess(), showError(), showInfo() and showWarning() in any component.

so let's put bellow code:

run bellow command:

ng generate service notification

src/app/notification.service.ts

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)

}

}

Step 5: Updated View File

Now here, we will updated our html file. we will create simple four buttons for alert messages.

so let's put bellow code:

src/app/app.component.html

<h1>Angular 8 Toastr Notifications Example - ItSolutionStuff.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 6: Use Component ts File

Now we need to update our component.ts file here we will use notification service and call alert, let's update as like bellow:

src/app/app.component.ts

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")

}

}

Now we are ready to run both:

Run Angular App:

ng serve

I hope it can help you...
