@angular/animations package is a required dependency for the default toast

npm install @angular/animations --save

Don't want to use @angular/animations? See Setup Without Animations.

Setup

step 1: add css

copy toast css to your project.
If you are using sass you can import the css.

// regular style toast
@import 'ngx-toastr/toastr';

// bootstrap style toast
// or import a bootstrap 4 alert styled design (SASS ONLY)
// should be after your bootstrap imports, it uses bs4 variables, mixins, functions
@import 'ngx-toastr/toastr-bs4-alert';

// if you'd like to use it without importing all of bootstrap it requires
@import 'bootstrap/scss/functions';
@import 'bootstrap/scss/variables';
@import 'bootstrap/scss/mixins';
// bootstrap 4
@import 'ngx-toastr/toastr-bs4-alert';
// boostrap 5
@import 'ngx-toastr/toastr-bs5-alert';

If you are using angular-cli you can add it to your angular.json

"styles": [
  "styles.scss",
  "node_modules/ngx-toastr/toastr.css" // try adding '../' if you're using angular cli before 6
]

step 2: add ToastrModule to app NgModule, or provideToastr to providers, make sure you have BrowserAnimationsModule (or provideAnimations) as well.

Module based

import { CommonModule } from '@angular/common';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

import { ToastrModule } from 'ngx-toastr';

@NgModule({
  imports: [
    CommonModule,
    BrowserAnimationsModule, // required animations module
    ToastrModule.forRoot(), // ToastrModule added
  ],
  bootstrap: [App],
  declarations: [App],
})
class MainModule {}

Standalone

import { AppComponent } from './src/app.component';
import { provideAnimations } from '@angular/platform-browser/animations';

import { provideToastr } from 'ngx-toastr';

bootstrapApplication(AppComponent, {
  providers: [
    provideAnimations(), // required animations providers
    provideToastr(), // Toastr providers
  ]
});

Use

import { ToastrService } from 'ngx-toastr';

@Component({...})
export class YourComponent {
  constructor(private toastr: ToastrService) {}

  showSuccess() {
    this.toastr.success('Hello world!', 'Toastr fun!');
  }
}

Options

There are individual options and global options.

Individual Options

Passed to ToastrService.success/error/warning/info/show()

Option	Type	Default	Description
toastComponent	Component	Toast	Angular component that will be used
closeButton	boolean	false	Show close button
timeOut	number	5000	Time to live in milliseconds
extendedTimeOut	number	1000	Time to close after a user hovers over toast
disableTimeOut	`boolean \| 'timeOut' \| 'extendedTimeOut'`	false	Disable both timeOut and extendedTimeOut when set to `true`. Allows specifying which timeOut to disable, either: `timeOut` or `extendedTimeOut`
easing	string	'ease-in'	Toast component easing
easeTime	string \| number	300	Time spent easing
enableHtml	boolean	false	Allow html in message
newestOnTop	boolean	true	New toast placement
progressBar	boolean	false	Show progress bar
progressAnimation	`'decreasing' \| 'increasing'`	'decreasing'	Changes the animation of the progress bar.
toastClass	string	'ngx-toastr'	CSS class(es) for toast
positionClass	string	'toast-top-right'	CSS class(es) for toast container
titleClass	string	'toast-title'	CSS class(es) for inside toast on title
messageClass	string	'toast-message'	CSS class(es) for inside toast on message
tapToDismiss	boolean	true	Close on click
onActivateTick	boolean	false	Fires `changeDetectorRef.detectChanges()` when activated. Helps show toast from asynchronous events outside of Angular's change detection

Setting Individual Options

success, error, info, warning take (message, title, ToastConfig) pass an options object to replace any default option.

this.toastrService.error('everything is broken', 'Major Error', {
  timeOut: 3000,
});

Global Options

All individual options can be overridden in the global options to affect all toasts. In addition, global options include the following options:

Option	Type	Default	Description
maxOpened	number	0	Max toasts opened. Toasts will be queued. 0 is unlimited
autoDismiss	boolean	false	Dismiss current toast when max is reached
iconClasses	object	see below	Classes used on toastr service methods
preventDuplicates	boolean	false	Block duplicate messages
countDuplicates	boolean	false	Displays a duplicates counter (preventDuplicates must be true). Toast must have a title and duplicate message
resetTimeoutOnDuplicate	boolean	false	Reset toast timeout on duplicate (preventDuplicates must be true)
includeTitleDuplicates	boolean	false	Include the title of a toast when checking for duplicates (by default only message is compared)

iconClasses defaults

iconClasses = {
  error: 'toast-error',
  info: 'toast-info',
  success: 'toast-success',
  warning: 'toast-warning',
};

Setting Global Options

Pass values to ToastrModule.forRoot() or provideToastr() to set global options.

Module based

// root app NgModule
imports: [
  ToastrModule.forRoot({
    timeOut: 10000,
    positionClass: 'toast-bottom-right',
    preventDuplicates: true,
  }),
],

Standalone

import { AppComponent } from './src/app.component';
import { provideAnimations } from '@angular/platform-browser/animations';

import { provideToastr } from 'ngx-toastr';

bootstrapApplication(AppComponent, {
  providers: [
    provideToastr({
      timeOut: 10000,
      positionClass: 'toast-bottom-right',
      preventDuplicates: true,
    }), 
  ]
});

Toastr Service methods return:

export interface ActiveToast {
  /** Your Toast ID. Use this to close it individually */
  toastId: number;
  /** the title of your toast. Stored to prevent duplicates if includeTitleDuplicates set */
  title: string;
  /** the message of your toast. Stored to prevent duplicates */
  message: string;
  /** a reference to the component see portal.ts */
  portal: ComponentRef<any>;
  /** a reference to your toast */
  toastRef: ToastRef<any>;
  /** triggered when toast is active */
  onShown: Observable<any>;
  /** triggered when toast is destroyed */
  onHidden: Observable<any>;
  /** triggered on toast click */
  onTap: Observable<any>;
  /** available for your use in custom toast */
  onAction: Observable<any>;
}

Put toasts in your own container

Put toasts in a specific div inside your application. This should probably be somewhere that doesn't get deleted. Add ToastContainerModule to the ngModule where you need the directive available. Make sure that your container has an aria-live="polite" attribute, so that any time a toast is injected into the container it is announced by screen readers.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

import { ToastrModule, ToastContainerModule } from 'ngx-toastr';

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

@NgModule({
  declarations: [AppComponent],
  imports: [
    BrowserModule,
    BrowserAnimationsModule,

    ToastrModule.forRoot({ positionClass: 'inline' }),
    ToastContainerModule,
  ],
  providers: [],
  bootstrap: [AppComponent],
})
export class AppModule {}

Add a div with toastContainer directive on it.

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

import { ToastContainerDirective, ToastrService } from 'ngx-toastr';

@Component({
  selector: 'app-root',
  template: `
    <h1><a (click)="onClick()">Click</a></h1>
    <div aria-live="polite" toastContainer></div>
  `,
})
export class AppComponent implements OnInit {
  @ViewChild(ToastContainerDirective, { static: true })
  toastContainer: ToastContainerDirective;

  constructor(private toastrService: ToastrService) {}
  ngOnInit() {
    this.toastrService.overlayContainer = this.toastContainer;
  }
  onClick() {
    this.toastrService.success('in div');
  }
}

Functions

Clear

Remove all or a single toast by optional id

toastrService.clear(toastId?: number);

Remove

Remove and destroy a single toast by id

toastrService.remove(toastId: number);

SystemJS

If you are using SystemJS, you should also adjust your configuration to point to the UMD bundle.

In your SystemJS config file, map needs to tell the System loader where to look for ngx-toastr:

map: {
  'ngx-toastr': 'node_modules/ngx-toastr/bundles/ngx-toastr.umd.min.js',
}

Setup Without Animations

If you do not want to include @angular/animations in your project you can override the default toast component in the global config to use ToastNoAnimation instead of the default one.

In your main module (ex: app.module.ts)

import { ToastrModule, ToastNoAnimation, ToastNoAnimationModule } from 'ngx-toastr';

@NgModule({
  imports: [
    // ...

    // BrowserAnimationsModule no longer required
    ToastNoAnimationModule.forRoot(),
  ],
  // ...
})
class AppModule {}

That's it! Animations are no longer required.

Using A Custom Toast

Create your toast component extending Toast see the demo's pink toast for an example https://github.com/scttcper/ngx-toastr/blob/master/src/app/pink.toast.ts

import { ToastrModule } from 'ngx-toastr';

@NgModule({
  imports: [
    ToastrModule.forRoot({
      toastComponent: YourToastComponent, // added custom toast!
    }),
  ],
  bootstrap: [App],
  declarations: [App, YourToastComponent], // add!
})
class AppModule {}
