Installation

npm install ng2-toasty --save

Demo

Simple examples using ng2-dnd:

• with SystemJS in ng2-systemjs-demo
• with Webpack in ng2-webpack-demo

Online demo available here

Plunker demo available here

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.

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 {
}

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 {
}

3. 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;
        }
    }
}

5. How to close specific toast

Here is an example of how to close an 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 subscription: Subscription;
        
        let toastOptions: ToastOptions = {
            title: this.getTitle(0),
            msg: this.getMessage(0),
            showClose: true,
            onAdd: (toast: ToastData) => {
                console.log('Toast ' + toast.id + ' has been added!');
                // Run the timer with 1 second iterval
                let observable = Observable.interval(interval);
                // Start listen seconds beat
                subscription = observable.subscribe((count: number) => {
                    // Update title of toast
                    toast.title = this.getTitle(count);
                    // Update message of toast
                    toast.msg = this.getMessage(count);
                    // 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);
                    }
                });

            },
            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;
        }
    }
}
