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'
    },
    packages: {
        'ng2-toasty':  { main: 'index.js',  defaultExtension: 'js' },
    }
});

Finally, you can use ng2-toasty in your Angular 2 project:

• Import ToastyService, ToastyConfig, ToastyComponent, ToastOptions from ng2-toasty
• Instantiate ToastyService, ToastyConfig in the bootstrap of your application;
• Add ToastyComponent to the "directives" property of your application component;
• Add <ng2-toasty></ng2-toasty> tag in template of your application component.

import {Component} from '@angular/core';
import {ToastyService, ToastyConfig, ToastyComponent, ToastOptions, ToastData} from 'ng2-toasty';
import {bootstrap} from '@angular/platform/browser';

@Component({
    selector: 'app',
    directives: [ToastyComponent],
    providers: [ToastyService, ToastyConfig],
    template: `
        <div>Hello world</div>
        <button (click)="addToast()">Add Toast</button>
        <ng2-toasty></ng2-toasty>
    `
})
export class AppComponent {
    
    constructor(private toastyService:ToastyService) { }
    
    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);
    }
}
