Getting Started With Default Configuration - NgModule:

import {NgModule, Component} from '@angular/core';
import {ToasterModule, ToasterService} from 'angular2-toaster/angular2-toaster';
import {Root} from './root.component'

@NgModule({
    imports: [ToasterModule],
    declarations: [Root],
    providers: [],
    bootstrap: [Root]
})

@Component({
    selector: 'root',
    template: `
            <toaster-container></toaster-container>
            <button (click)="popToast()">pop toast</button>`
})

export class Root {
    private toasterService: ToasterService;

    constructor(toasterService: ToasterService) {
        this.toasterService = toasterService;
    }

    popToast() {
        this.toasterService.pop('success', 'Args Title', 'Args Body');
    }
}

Getting Started with Default Configuration - Manual Component Inclusion:

import {Component} from '@angular/core';
import {ToasterContainerComponent, ToasterService} from 'angular2-toaster/angular2-toaster';

@Component({
    selector: 'root',
    directives: [ToasterContainerComponent],
    providers: [ToasterService],
    template: `
        <toaster-container></toaster-container>
        <button (click)="popToast()">pop toast</button>`
})

class Root {
    private toasterService: ToasterService;
    
    constructor(toasterService: ToasterService) {
        this.toasterService = toasterService;    
    }
    
    popToast() {
        this.toasterService.pop('success', 'Args Title', 'Args Body');
    }
}

bootstrap(Root);

Getting Started with Configuration Override:

import {Component} from '@angular/core';
import {ToasterContainerComponent, ToasterService, ToasterConfig} from 'angular2-toaster/angular2-toaster';

@Component({
    selector: 'root',
    directives: [ToasterContainerComponent],
    providers: [ToasterService],
    template: `
        <toaster-container [toasterconfig]="toasterconfig">
        </toaster-container>
        <button (click)="popToast()">pop toast</button>`
})

class Root {
    private toasterService: ToasterService;
    
    constructor(toasterService: ToasterService) {
        this.toasterService = toasterService;    
    }
    
    public toasterconfig : ToasterConfig = 
        new ToasterConfig({
            showCloseButton: true, 
            tapToDismiss: false, 
            timeout: 0
        });
    
    popToast() {
        this.toasterService.pop('success', 'Args Title', 'Args Body');
    }
}

bootstrap(Root);

Asynchronous vs Synchronous ToasterService

ToasterService exposes both a synchronous and asynchronous pop method in the form of pop() and popAsync() respectively.

pop() returns a concrete Toast instance after the toastId property has been hydrated and the toast has been added to all receiving containers.

popAsync() returns a hot Observable<Toast> that may be subscribed to to receive multiple toast updates.

Customize Toast arguments in pop

var toast: Toast = {
    type: 'success',
    title: 'close button',
    showCloseButton: true
};

this.toasterService.pop(toast);

Clear Existing Toast

ToasterService exposes a clear function that accepts two optional parameters: toastId and toastContainerId.

These parameters can be used to clear toasts by specific id, by container id, by both, or by neither. If both parameters are omitted, all toasts in all containers will be removed.

var toast = this.toasterService.pop('success', 'title', 'body');
this.toasterService.clear(toast.toastId, toast.toastContainerId);

Configurable Options

Limit

Limit is defaulted to null, meaning that there is no maximum number of toasts that are defined before the toast container begins removing toasts when a new toast is added.

To change this behavior, pass a "limit" option to the config:

template: 
    `<toaster-container [toasterconfig]="toasterconfig"></toaster-container>`

public toasterconfig : ToasterConfig = 
    new ToasterConfig({limit: 5});

Tap to Dismiss

By default, the tapToDismiss option is set to true, meaning that if a toast is clicked anywhere on the toast body, the toast will be dismissed. This behavior can be overriden in the config so that if set to false, the toast will only be dismissed if the close button is defined and clicked:

template: 
    `<toaster-container [toasterconfig]="toasterconfig"></toaster-container>`

public toasterconfig : ToasterConfig = 
    new ToasterConfig({tapToDismiss: false});

Close Button

The Close Button's visibility can be configured at three different levels:

• Globally in the config for all toast types:

  template: 
      `<toaster-container [toasterconfig]="toasterconfig"></toaster-container>`
  
  public toasterconfig : ToasterConfig = 
      new ToasterConfig({showCloseButton: true});

• Per info-class type: By passing the close-button configuration as an object instead of a boolean, you can specify the global behavior an info-class type should have.

  template: 
      `<toaster-container [toasterconfig]="toasterconfig"></toaster-container>`
  
  public toasterconfig : ToasterConfig = 
      new ToasterConfig({
          showCloseButton: { 'warning': true, 'error': false }
      });

  If a type is not defined and specified, the default behavior for that type is false.

• Per toast constructed via Toast object creation:

  var toast : Toast = {
      type: 'error',
      title: 'Title text',
      body: 'Body text',
      showCloseButton: true
  };
  
  this.toasterService.pop(toast);

  This option is given the most weight and will override the global configurations for that toast. However, it will not persist to other toasts of that type and does not alter or pollute the global configuration.

Close Html

The close button html can be overridden either globally or per toast call.

• Globally:

  template: 
      `<toaster-container [toasterconfig]="toasterconfig"></toaster-container>`
  
  public toasterconfig : ToasterConfig = 
      new ToasterConfig({
          closeHtml: '<button>Close</button>'
      });

• Per toast:

  var toast : Toast = {
      type: 'error',
      title: 'Title text',
      body: 'Body text',
      showCloseButton: true,
      closeHtml: '<button>Close</button>'
  };
  
  this.toasterService.pop(toast);

Newest Toasts on Top

The newestOnTop option is defaulted to true, adding new toasts on top of other existing toasts. If changed to false via the config, toasts will be added to the bottom of other existing toasts.

template: 
    `<toaster-container [toasterconfig]="toasterconfig"></toaster-container>`

public toasterconfig : ToasterConfig = 
    new ToasterConfig({newestOnTop: false});

Timeout

By default, toasts have a timeout setting of 5000, meaning that they are removed after 5000 milliseconds.

If the timeout is set to anything other than a number greater than 0, the toast will be considered "sticky" and will not automatically dismiss.

The timeout can be configured at three different levels:

• Globally in the config for all toast types:

  template: 
    `<toaster-container [toasterconfig]="toasterconfig"></toaster-container>`
  
  public toasterconfig : ToasterConfig = 
        new ToasterConfig({timeout: 2000});

• Per info-class type: By passing the timeout config option as an object instead of a number, you can specify the global behavior an info-class type should have.

  template: 
    `<toaster-container [toasterconfig]="toasterconfig"></toaster-container>`
  
  public toasterconfig : ToasterConfig = 
      new ToasterConfig({timeout: {error:1000});

If a type is not defined and specified, a timeout will not be applied, making the toast "sticky".

• Per toast constructed via toaster.pop('success', "title", "text"):

  var toast : Toast = {
      type: 'error',
      title: 'Title text',
      body: 'Body text',
      showCloseButton: true,
      closeHtml: '<button>Close</button>'
  };
    
  this.toasterService.pop(toast);

Body Output Type

There are three different types of body renderings that can be passed via the toast.bodyOutputType argument: 'Default', 'TrustedHtml', and 'Component'. If a bodyOutputType is not provided, it will be defaulted to 'Default'.

• Default: The body argument will be directly interpolated as text content. If html is passed in the body argument, it will be encoded and rendered as text.

• TrustedHtml: The body argument will be parsed and rendered as html content.

  import {BodyOutputType} from 'angular2-toaster/angular2-toaster';
  var toast : Toast = {
      type: 'error',
      title: 'Title text',
      body: '<h4>Body text</h4>',
      bodyOutputType: BodyOutputType.TrustedHtml
  };
            
  this.toasterService.pop(toast);

• Component: The body argument is the name of the component class to be rendered as the content of the toast.

  import {BodyOutputType} from 'angular2-toaster/angular2-toaster';
  
  @Component({
    selector: 'dynamic-component',
    template: `<div>loaded via component</div>`
  })
  class DynamicComponent { }
  
  var toast : Toast = {
      type: 'error',
      title: 'Title text',
      body: DynamicComponent,
      bodyOutputType: BodyOutputType.Component
  };
            
  this.toasterService.pop(toast);

On Show Callback

An onShow callback function can be attached to each toast instance. The callback will be invoked upon toast add.

var toast: Toast = {
  type: 'success',
  title: 'parent',
  onShowCallback: (toast) => this.toasterService.pop('success', 'invoked from ' + toast.title + ' onShow callback')  
};

this.toasterService.pop(toast);

On Hide Callback

An onHide callback function can be attached to each toast instance. The callback will be invoked upon toast removal.

var toast: Toast = {
  type: 'success',
  title: 'parent',
  onHideCallback: (toast) => this.toasterService.pop('success', 'invoked from ' + toast.title + ' onHide callback')  
};

this.toasterService.pop(toast);

Animations

Animations will be included at a later point in time.
