Angular5-Toaster

angular5-toaster is an asynchronous, non-blocking, Ahead of Time Compilation-supported Angular Toaster Notification library
largely based off of AngularJS-Toaster and angular2-Toaster.


Getting Started

Installation:

``bash
npm install angular5-toaster
`

Import CSS

$3


`html

`

$3

`scss
@import 'node_modules/angular5-toaster/toaster';
`

Import Library

$3

Within the map property of the systemjs.config file, add mappings for angular, rxjs
(which is a dependency), and the angular5-toaster bundled umd file:

`javascript
map: {
// angular bundles
'@angular/core': 'npm:@angular/core/bundles/core.umd.js',
// ...
// other libraries
'rxjs': 'npm:rxjs',
'angular5-toaster': 'npm:angular5-toaster/bundles/angular5-toaster.umd.js'
`

$3


Simply follow the Getting Started instructions to import the library.

Getting Started With Default Configuration - NgModule (Recommended):

`typescript
import {NgModule, Component} from '@angular/core';
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';
import {ToasterModule, ToasterService} from 'angular5-toaster';
import {Root} from './root.component'

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

@Component({
selector: 'root',
template:

pop toast
})

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:

`typescript
import {Component} from '@angular/core';
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';
import {ToasterContainerComponent, ToasterService} from 'angular5-toaster';

@Component({
selector: 'root',
imports: [BrowserAnimationsModule],
directives: [ToasterContainerComponent],
providers: [ToasterService],
template:

pop toast
})

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:

`typescript
import {Component} from '@angular/core';
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';
import {ToasterContainerComponent, ToasterService, ToasterConfig} from 'angular5-toaster';

@Component({
selector: 'root',
imports: [BrowserAnimationsModule],
directives: [ToasterContainerComponent],
providers: [ToasterService],
template:


pop toast
})

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 that may be subscribed to to receive multiple toast
updates.




Customize Toast arguments in pop


`typescript

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.

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




Animations


Starting with version 4.0.0 and greater, Animation configuration is required, as described in the
Getting Started section.

To add animations:

- Install the @angular/animations npm package via
npm install @angular/animations.
- Add the BrowserAnimationsModule to your root module

`typescript
import {NgModule, Component} from '@angular/core';
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';
import {ToasterModule} from 'angular5-toaster';

@NgModule({
imports: [BrowserAnimationsModule, ToasterModule],
...
`

If you want to avoid bringing in an additional module solely for the sake of animations, you can
explicitly configure angular5-toaster to ignore animations. To do so, import the
NoopAnimationsModule instead:

`typescript
import {NoopAnimationsModule} from '@angular/platform-browser/animations';
import {ToasterModule} from 'angular5-toaster';

@NgModule({
imports: [NoopAnimationsModule, ToasterModule],
...
`

Angular Animations require browsers that support the Web Animations Standard.

If you need to target a non-supported browser, a polyfill is required.




Configurable Options

$3

There are five animation styles that can be applied via the toasterconfig animation property:
'fade', 'flyLeft', 'flyRight', 'slideDown', and 'slideUp'. Any other value will disable animations.

`typescript
template:


public toasterconfig : ToasterConfig =
new ToasterConfig({animation: 'fade'});
`

$3

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:

`typescript
template:


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

$3


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:

`typescript
template:


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

$3

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

* Globally in the config for all toast types:

`typescript
template:


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.

`typescript
template:


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:

`typescript
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.




$3

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

- Globally:

`typescript
template:


public toasterconfig : ToasterConfig =
new ToasterConfig({
closeHtml: 'Close'
});
`

- Per toast:

`typescript
var toast : Toast = {
type: 'error',
title: 'Title text',
body: 'Body text',
showCloseButton: true,
closeHtml: 'Close'
};

this.toasterService.pop(toast);
`

$3


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.

`typescript
template:


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

$3

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:
`typescript
template:


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:


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"):
`typescript
var toast : Toast = {
type: 'error',
title: 'Title text',
body: 'Body text',
showCloseButton: true,
closeHtml: 'Close'
};

this.toasterService.pop(toast);
`

$3

By default, all toasts are dismissed when their timer expires, even if you mouse over the toast.
This can be overriden via the container's config.

`typescript
template:


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

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.
`typescript
import {BodyOutputType} from 'angular5-toaster';
var toast : Toast = {
type: 'error',
title: 'Title text',
body: '

Body text

',
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.
`typescript
import {BodyOutputType} from 'angular5-toaster';

@Component({
selector: 'dynamic-component',
template:


})
class DynamicComponent { }

var toast : Toast = {
type: 'error',
title: 'Title text',
body: DynamicComponent,
bodyOutputType: BodyOutputType.Component
};

this.toasterService.pop(toast);
`

The Component BodyOutputType offers the additional flexibilty of attaching the toast instance to
your component. It is recommended that you expose a public property on your component for type
safe access to the toast instance if you need to consume it inside of your component.
Mutation of the toast instance is not recommended.

$3

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

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

this.toasterService.pop(toast);
`

$3

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

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

this.toasterService.pop(toast);
`
