Steps to Change the Position of a Specific Toast

Step 1: Setting up the Angular Project

First, we will set up an angular project, and install the ngx-toastr dependencies.

ng new angular-toastr --standalone
cd angular-toastr
npm install ngx-toastr
npm install @angular/animations

"dependencies": {
    "@angular/animations": "^18.1.1",
    "@angular/common": "^18.0.0",
    "@angular/compiler": "^18.0.0",
    "@angular/core": "^18.0.0",
    "@angular/forms": "^18.0.0",
    "@angular/platform-browser": "^18.0.0",
    "@angular/platform-browser-dynamic": "^18.0.0",
    "@angular/router": "^18.0.0",
    "ngx-toastr": "^19.0.0",
    "rxjs": "~7.8.0",
    "tslib": "^2.3.0",
    "zone.js": "~0.14.3"
  },
  "devDependencies": {
    "@angular-devkit/build-angular": "^18.0.7",
    "@angular/cli": "^18.0.7",
    "@angular/compiler-cli": "^18.0.0",
    "@types/jasmine": "~5.1.0",
    "jasmine-core": "~5.1.0",
    "karma": "~6.4.0",
    "karma-chrome-launcher": "~3.2.0",
    "karma-coverage": "~2.2.0",
    "karma-jasmine": "~5.1.0",
    "karma-jasmine-html-reporter": "~2.1.0",
    "typescript": "~5.4.2"
  }

Step 2: Configuring ngx-toastr

In this step, we will add the ngx-toastr and browser animations to our app config file.

JavaScript 
// Filename: app.config.ts
import {
    ApplicationConfig,
    provideZoneChangeDetection
} from "@angular/core";
import {
    provideAnimations
} from "@angular/platform-browser/animations";
import {provideRouter} from "@angular/router";
import {provideToastr} from "ngx-toastr";

import {routes} from "./app.routes";

export const appConfig: ApplicationConfig = {
    providers : [
        provideZoneChangeDetection(
            {eventCoalescing : true}),
        provideRouter(routes), provideAnimations(),
        provideToastr()
    ]
};


Step 3: Create a standalone toastr notifications component

Create a standalone toastr notifications components that we will use in our main app component to render the notifications. Use the below command to create a standalone component.

ng generate component toast-demo --standalone

Now, update the toast-demo.component.ts file to include the toast notifications.

JavaScript 
// Filename: toast-demo.component.ts
import {Component} from "@angular/core";
import {ToastrService} from "ngx-toastr";

@Component({
    selector : "app-toast-demo",
    standalone : true,
    styleUrl : "./toast-demo.component.css",
    imports : [],
    template : `
    <div>
      <button (click)="showTopRightToast()">Show Top Right Toast</button>
      <button (click)="showTopLeftToast()">Show Top Left Toast</button>
    </div>
  `,
    providers : [ ToastrService ]
})
export class ToastDemoComponent {
    constructor(private toastr: ToastrService) {}

    showTopRightToast()
    {
        this.toastr.show(
            "This is a top-right toast", "Toast Title", {
                positionClass : "toast-top-right",
            });
    }

    showTopLeftToast()
    {
        this.toastr.show(
            "This is a top-left toast", "Toast Title",
            {positionClass : "toast-top-left"});
    }
}


Step 4: Add the toast-demo component inside the app component

Use the newly created toast-demo component inside the app component.

JavaScript 
// Filename: app.component.ts
import {Component} from "@angular/core";
import {RouterOutlet} from "@angular/router";
import {
    ToastDemoComponent
} from "./toast-demo/toast-demo.component";

@Component({
    selector : "app-root",
    standalone : true,
    imports : [ RouterOutlet, ToastDemoComponent ],
    template : `
    <app-toast-demo></app-toast-demo>
  `,
    styleUrl : "./app.component.css"
})
export class AppComponent {
    title = "angular-toast";
}

Step 5: Add CSS for toastr notifications

Add the below CSS for showing the toastr notifications animations.

CSS 
/* styles.css */

.toast-center-center {
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
}

.toast-top-center {
    top: 0;
    right: 0;
    width: 100%;
}

.toast-bottom-center {
    bottom: 0;
    right: 0;
    width: 100%;
}

.toast-top-full-width {
    top: 0;
    right: 0;
    width: 100%;
}

.toast-bottom-full-width {
    bottom: 0;
    right: 0;
    width: 100%;
}

.toast-top-left {
    top: 12px;
    left: 12px;
}

.toast-top-right {
    top: 12px;
    right: 12px;
}

.toast-bottom-right {
    right: 12px;
    bottom: 12px;
}

.toast-bottom-left {
    bottom: 12px;
    left: 12px;
}

/* toast styles */
.toast-title {
    font-weight: bold;
}

.toast-message {
    word-wrap: break-word;
}

.toast-message a,
.toast-message label {
    color: #FFFFFF;
}

.toast-message a:hover {
    color: #CCCCCC;
    text-decoration: none;
}

.toast-close-button {
    position: relative;
    right: -0.3em;
    top: -0.3em;
    float: right;
    font-size: 20px;
    font-weight: bold;
    color: #FFFFFF;
    text-shadow: 0 1px 0 #ffffff;
    /* opacity: 0.8; */
}

.toast-close-button:hover,
.toast-close-button:focus {
    color: #000000;
    text-decoration: none;
    cursor: pointer;
    opacity: 0.4;
}

button.toast-close-button {
    padding: 0;
    cursor: pointer;
    background: transparent;
    border: 0;
}

.toast-container {
    pointer-events: none;
    position: fixed;
    z-index: 999999;
}

.toast-container * {
    box-sizing: border-box;
}

.toast-container .ngx-toastr {
    position: relative;
    overflow: hidden;
    margin: 0 0 6px;
    padding: 15px 15px 15px 50px;
    width: 300px;
    border-radius: 3px 3px 3px 3px;
    background-position: 15px center;
    background-repeat: no-repeat;
    background-size: 24px;
    box-shadow: 0 0 12px #999999;
    color: #FFFFFF;
}

.toast-container .ngx-toastr:hover {
    box-shadow: 0 0 12px #000000;
    opacity: 1;
    cursor: pointer;
}

.toast-info {
