Installation
npm install ngx-toastaDemo

Usage
If you use SystemJS to load your files, you might have to update your config:
System.config({
map: {
'ngx-toasta': 'node_modules/ngx-toasta/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 themestyle-bootstrap.css- Contains Bootstrap 3 themestyle-material.css- Contains Material Design theme
- Assign the selected theme name [
default,bootstrap,material] to thethemeproperty of the instance of ToastaConfig. - Add
<ngx-toasta></ngx-toasta>tag in template of your application component.
2. Import the ToastaModule
Import ToastaModule.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 {ToastaModule} from 'ngx-toasta';
@NgModule({
imports: [
BrowserModule,
ToastaModule.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 ToastaModule that you imported in order to avoid having to import it multiple times.
@NgModule({
imports: [
BrowserModule,
ToastaModule.forRoot()
],
exports: [BrowserModule, ToastaModule],
})
export class SharedModule {
}3. Use the ToastaService for your application
- Import
ToastaServicefromngx-toastain your application code:
import {Component} from '@angular/core';
import {ToastaService, ToastaConfig, ToastOptions, ToastData} from 'ngx-toasta';
@Component({
selector: 'app',
template: `
<div>Hello world</div>
<button (click)="addToast()">Add Toast</button>
<ngx-toasta></ngx-toasta>
`
})
export class AppComponent {
constructor(private toastaService:ToastaService, private toastaConfig: ToastaConfig) {
// Assign the selected theme name to the `theme` property of the instance of ToastaConfig.
// Possible values: default, bootstrap, material
this.toastaConfig.theme = 'material';
}
addToast() {
// Just add default Toast with title only
this.toastaService.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.toastaService.info(toastOptions);
this.toastaService.success(toastOptions);
this.toastaService.wait(toastOptions);
this.toastaService.error(toastOptions);
this.toastaService.warning(toastOptions);
}
}4. How to 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 {ToastaService, ToastaConfig, ToastaComponent, ToastOptions, ToastData} from 'ngx-toasta';
import {Subject, Observable, Subscription} from 'rxjs/Rx';
@Component({
selector: 'app',
template: `
<div>Hello world</div>
<button (click)="addToast()">Add Toast</button>
<ngx-toasta></ngx-toasta>
`
})
export class AppComponent {
getTitle(num: number): string {
return 'Countdown: ' + num;
}
getMessage(num: number): string {
return 'Seconds left: ' + num;
}
constructor(private toastaService:ToastaService) { }
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.toastaService.default(toastOptions); break;
case 'info': this.toastaService.info(toastOptions); break;
case 'success': this.toastaService.success(toastOptions); break;
case 'wait': this.toastaService.wait(toastOptions); break;
case 'error': this.toastaService.error(toastOptions); break;
case 'warning': this.toastaService.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 {ToastaService, ToastaConfig, ToastaComponent, ToastOptions, ToastData} from 'ngx-toasta';
import {Subject, Observable, Subscription} from 'rxjs/Rx';
@Component({
selector: 'app',
template: `
<div>Hello world</div>
<button (click)="addToast()">Add Toast</button>
<ngx-toasta></ngx-toasta>
`
})
export class AppComponent {
getTitle(num: number): string {
return 'Countdown: ' + num;
}
getMessage(num: number): string {
return 'Seconds left: ' + num;
}
constructor(private toastaService:ToastaService) { }
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.toastaService.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.toastaService.default(toastOptions); break;
case 'info': this.toastaService.info(toastOptions); break;
case 'success': this.toastaService.success(toastOptions); break;
case 'wait': this.toastaService.wait(toastOptions); break;
case 'error': this.toastaService.error(toastOptions); break;
case 'warning': this.toastaService.warning(toastOptions); break;
}
}
}6. Customize the ngx-toasta for your application in template
You can use the following properties to customize the ngx-toasta component in your template:
position- The window position where the toast pops up. Default value isbottom-right. Possible values:bottom-right,bottom-left,bottom-fullwidthtop-right,top-left,top-fullwidth,top-center,bottom-center,center-centerExample:
<ngx-toasta [position]="'top-center'"></ngx-toasta>7. Options
Use these options to configure individual or global toasts
Options specific to an individual toast:
ToastOptions
{
"title": string, //A string or html for the title
"msg": string, //A string or html for the message
"showClose": true, //Whether to show a close button
"theme": "default", //The theme to apply to this toast
"timeout": 5000, //Time to live until toast is removed. 0 is unlimited
"onAdd": Function, //Function that gets called after this toast is added
"onRemove": Function //Function that gets called after this toast is removed
}Configurations that affects all toasts:
ToastaConfig
{
"limit": 5, //Maximum toasts that can be shown at once. Older toasts will be removed. 0 is unlimited
"showClose": true, //Whether to show the 'x' icon to close the toast
"position": "bottom-right", //The window position where the toast pops up
"timeout": 5000, //Time to live in milliseconds. 0 is unlimited
"theme": "default" //What theme to use
