Usage

If you use SystemJS to load your files, you might have to update your config:
 System.config({  
   map: {  
     'ng2-toasty': 'node_modules/ng2-toasty/bundles/index.umd.js'  
   }  
 }); 

  1. Update the markup

  • Import style into your web page. Choose one of the following files;
    • style-default.css - Contains DEFAULT theme
    • style-bootstrap.css - Contains Bootstrap 3 theme
    • style-material.css - Contains Material Design theme
  • Assign the selected theme name [default, bootstrap, material] to the theme property of the instance of ToastyConfig.
  • Add <ng2-toasty></ng2-toasty> tag in template of your application component.

2. Import the ToastyModule

Import ToastyModule.forRoot() in the NgModule of your application. The forRoot method is a convention for modules that provide a singleton service.
 <pre style="font-family:arial;font-size:12px;border:1px dashed #CCCCCC;width:99%;height:auto;overflow:auto;background:#f0f0f0;padding:0px;color:#000000;text-align:left;line-height:20px;"><code style="color:#000000;word-wrap:normal;"> import {BrowserModule} from "@angular/platform-browser";   
  import {NgModule} from '@angular/core';   
  import {ToastyModule} from 'ng2-toasty';   
  @NgModule({   
   imports: [   
    BrowserModule,   
    ToastyModule.forRoot()   
   ],   
   bootstrap: [AppComponent]   
  })   
  export class AppModule {   
  }   
 </code></pre>  
If you have multiple NgModules and you use one as a shared NgModule (that you import in all of your other NgModules), don't forget that you can use it to export the ToastyModule that you imported in order to avoid having to import it multiple times.
 @NgModule({  
   imports: [  
     BrowserModule,  
     ToastyModule.forRoot()  
   ],  
   exports: [BrowserModule, ToastyModule],  
 })  
 export class SharedModule {  
 } 

Use the ToastyService for your application

  • Import ToastyService from ng2-toasty in your application code:

     

     import {Component} from '@angular/core';  
     import {ToastyService, ToastyConfig, ToastOptions, ToastData} from 'ng2-toasty';  
     @Component({  
       selector: 'app',  
       template: `  
         <div>Hello world</div>  
         <button (click)="addToast()">Add Toast</button>  
         <ng2-toasty></ng2-toasty>  
       `  
     })  
     export class AppComponent {  
       constructor(private toastyService:ToastyService, private toastyConfig: ToastyConfig) {   
         // Assign the selected theme name to the `theme` property of the instance of ToastyConfig.   
         // Possible values: default, bootstrap, material  
         this.toastyConfig.theme = 'material';  
       }  
       addToast() {  
         // Just add default Toast with title only  
         this.toastyService.default('Hi there');  
         // Or create the instance of ToastOptions  
         var toastOptions:ToastOptions = {  
           title: "My title",  
           msg: "The message",  
           showClose: true,  
           timeout: 5000,  
           theme: 'default',  
           onAdd: (toast:ToastData) => {  
             console.log('Toast ' + toast.id + ' has been added!');  
           },  
           onRemove: function(toast:ToastData) {  
             console.log('Toast ' + toast.id + ' has been removed!');  
           }  
         };  
         // Add see all possible types in one shot  
         this.toastyService.info(toastOptions);  
         this.toastyService.success(toastOptions);  
         this.toastyService.wait(toastOptions);  
         this.toastyService.error(toastOptions);  
         this.toastyService.warning(toastOptions);  
       }  
     } 

    4. How dynamically update title and message of a toast

    Here is an example of how to dynamically update message and title of individual toast:
     import {Component} from '@angular/core';  
     import {ToastyService, ToastyConfig, ToastyComponent, ToastOptions, ToastData} from 'ng2-toasty';  
     import {Subject, Observable, Subscription} from 'rxjs/Rx';  
     @Component({  
       selector: 'app',  
       template: `  
         <div>Hello world</div>  
         <button (click)="addToast()">Add Toast</button>  
         <ng2-toasty></ng2-toasty>  
       `  
     })  
     export class AppComponent {  
       getTitle(num: number): string {  
         return 'Countdown: ' + num;  
       }  
       getMessage(num: number): string {  
         return 'Seconds left: ' + num;  
       }  
       constructor(private toastyService:ToastyService) { }  
       addToast() {  
         let interval = 1000;  
         let timeout = 5000;  
         let seconds = timeout / 1000;  
         let subscription: Subscription;  
         let toastOptions: ToastOptions = {  
           title: this.getTitle(seconds),  
           msg: this.getMessage(seconds),  
           showClose: true,  
           timeout: timeout,  
           onAdd: (toast: ToastData) => {  
             console.log('Toast ' + toast.id + ' has been added!');  
             // Run the timer with 1 second iterval  
             let observable = Observable.interval(interval).take(seconds);  
             // Start listen seconds beat  
             subscription = observable.subscribe((count: number) => {  
               // Update title of toast  
               toast.title = this.getTitle(seconds - count - 1);  
               // Update message of toast  
               toast.msg = this.getMessage(seconds - count - 1);  
             });  
           },  
           onRemove: function(toast: ToastData) {  
             console.log('Toast ' + toast.id + ' has been removed!');  
             // Stop listenning  
             subscription.unsubscribe();  
           }  
         };  
         switch (this.options.type) {  
           case 'default': this.toastyService.default(toastOptions); break;  
           case 'info': this.toastyService.info(toastOptions); break;  
           case 'success': this.toastyService.success(toastOptions); break;  
           case 'wait': this.toastyService.wait(toastOptions); break;  
           case 'error': this.toastyService.error(toastOptions); break;  
           case 'warning': this.toastyService.warning(toastOptions); break;  
         }  
       }  
     }

               // Extra condition to hide Toast after 10 sec  
               if (count > 10) {  
                 // We use toast id to identify and hide it  
                 this.toastyService.clear(toast.id);
