DEMO: https://scttcper.github.io/ngx-toastr/
- Toast Component Injection without being passed
ViewContainerRef
- No use of
*ngFor
. Fewer dirty checks and higher performance. - AoT compilation and lazy loading compatible
- Component inheritance for custom toasts
- SystemJS/UMD rollup bundle
- Animations using Angular's Web Animations API (polyfill needed for older devices)
- Output toasts to an optional target directive
npm install ngx-toastr --save
@angular/animations
package is a required dependency for the default toast
npm install @angular/animations --save
Don't want to use @angular/animations
? See
Setup Without Animations.
step 1: add css
- copy toast css to your project.
- If you are using sass you can import the css.
@import "~ngx-toastr/toastr";
// or import a bootstrap 4 alert styled design (SASS ONLY)
// should be after your bootstrap imports, it uses bs4 variables
@import "~ngx-toastr/toastr-bs4-alert"
- If you are using angular-cli you can add it to your angular-cli.json
"styles": [
"styles.scss",
"../node_modules/ngx-toastr/toastr.css"
]
step 2: add ToastrModule to app NgModule
import { CommonModule } from '@angular/common';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { ToastrModule } from 'ngx-toastr';
@NgModule({
imports: [
CommonModule,
BrowserAnimationsModule, // required animations module
ToastrModule.forRoot(), // ToastrModule added
],
bootstrap: [App],
declarations: [App],
})
class MainModule {}
Success:
import { ToastrService } from 'ngx-toastr';
@Component({
...
})
export class YourComponent {
constructor(private toastr: ToastrService) {}
showSuccess() {
this.toastr.success('Hello world!', 'Toastr fun!');
}
}
There are individual options and global options.
Passed to ToastrService.success/error/warning/info/show()
Option | Type | Default | Description |
---|---|---|---|
toastComponent | Component | Toast | Angular component that will be used |
closeButton | boolean | false | Show close button |
timeOut | number | 5000 | Time to live in milliseconds |
extendedTimeOut | number | 1000 | Time to close after a user hovers over toast |
disableTimeOut | boolean | false | Disable both timeOut and extendedTimeOut |
easing | string | 'ease-in' | Toast component easing |
easeTime | string | number | 300 | Time spent easing |
enableHtml | boolean | false | Allow html in message |
progressBar | boolean | false | Show progress bar |
progressAnimation | 'decreasing' | 'increasing' |
'decreasing' | Changes the animation of the progress bar. |
toastClass | string | 'toast' | Class on toast |
positionClass | string | 'toast-top-right' | Class on toast container |
titleClass | string | 'toast-title' | Class inside toast on title |
messageClass | string | 'toast-message' | Class inside toast on message |
tapToDismiss | boolean | true | Close on click |
onActivateTick | boolean | false | Fires changeDetectorRef.detectChanges() when activated. Helps show toast from asynchronous events outside of Angular's change detection |
success, error, info, warning take (message, title, ToastConfig)
pass an
options object to replace any default option.
this.toastrService.error('everything is broken', 'Major Error', {
timeOut: 3000,
});
All individual options can be overridden in the global options to affect all toasts. In addition, global options include the following options:
Option | Type | Default | Description |
---|---|---|---|
maxOpened | number | 0 | Max toasts opened. Toasts will be queued. 0 is unlimited |
autoDismiss | boolean | false | Dismiss current toast when max is reached |
iconClasses | object | see below | Classes used on toastr service methods |
newestOnTop | boolean | true | New toast placement |
preventDuplicates | boolean | false | Block duplicate messages |
iconClasses = {
error: 'toast-error',
info: 'toast-info',
success: 'toast-success',
warning: 'toast-warning',
};
Pass values to ToastrModule.forRoot()
// root app NgModule
imports: [
ToastrModule.forRoot({
timeOut: 10000,
positionClass: 'toast-bottom-right',
preventDuplicates: true,
}),
],
Toastr Service will return undefined if prevent duplicates is enabled
export interface ActiveToast {
/** Your Toast ID. Use this to close it individually */
toastId: number;
/** the message of your toast. Stored to prevent duplicates */
message: string;
/** a reference to the component see portal.ts */
portal: ComponentRef<any>;
/** a reference to your toast */
toastRef: ToastRef<any>;
/** triggered when toast is active */
onShown: Observable<any>;
/** triggered when toast is destroyed */
onHidden: Observable<any>;
/** triggered on toast click */
onTap: Observable<any>;
/** available for your use in custom toast */
onAction: Observable<any>;
}
Put toasts in a specific div inside your application. This should probably be
somewhere that doesn't get deleted. Add ToastContainerModule
to the ngModule
where you need the directive available.
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { ToastrModule, ToastContainerModule } from 'ngx-toastr';
import { AppComponent } from './app.component';
@NgModule({
declarations: [AppComponent],
imports: [
BrowserModule,
BrowserAnimationsModule,
ToastrModule.forRoot({ positionClass: 'inline' }),
ToastContainerModule,
],
providers: [],
bootstrap: [AppComponent],
})
export class AppModule {}
Add a div with toastContainer
directive on it.
import { Component, OnInit, ViewChild } from '@angular/core';
import { ToastContainerDirective, ToastrService } from 'ngx-toastr';
@Component({
selector: 'app-root',
template: `
<h1><a (click)="onClick()">Click</a></h1>
<div toastContainer></div>
`,
})
export class AppComponent implements OnInit {
@ViewChild(ToastContainerDirective) toastContainer: ToastContainerDirective;
constructor(private toastrService: ToastrService) {}
ngOnInit() {
this.toastrService.overlayContainer = this.toastContainer;
}
onClick() {
this.toastrService.success('in div');
}
}
If you are using SystemJS, you should also adjust your configuration to point to the UMD bundle.
In your SystemJS config file, map
needs to tell the System loader where to
look for ngx-toastr
:
map: {
'ngx-toastr': 'node_modules/ngx-toastr/bundles/ngx-toastr.umd.min.js',
}
If you do not want to include @angular/animations
in your project you can
override the default toast component in the global config to use
ToastNoAnimation
instead of the default one.
In your main module (ex: app.module.ts
)
import {
ToastrModule,
ToastNoAnimation,
ToastNoAnimationModule,
} from 'ngx-toastr';
@NgModule({
imports: [
// ...
// BrowserAnimationsModule no longer required
ToastNoAnimationModule,
ToastrModule.forRoot({
toastComponent: ToastNoAnimation,
}),
],
// ...
})
class AppModule {}
That's it! Animations are no longer required.
Create your toast component extending Toast see the demo's pink toast for an example https://github.com/scttcper/ngx-toastr/blob/master/src/app/pink.toast.ts
import { ToastrModule } from 'ngx-toastr';
@NgModule({
imports: [
ToastrModule.forRoot({
toastComponent: YourToastComponent, // added custom toast!
}),
],
entryComponents: [YourToastComponent], // add!
bootstrap: [App],
declarations: [App, YourToastComponent], // add!
})
class AppModule {}
- ExpressionChangedAfterItHasBeenCheckedError: Expression has changed after it
was checked
When opening a toast inside an angular lifecycle wrap it in setTimeout
ngOnInit() {
setTimeout(() => this.toastr.success('sup'))
}
- Change default icons (check, warning sign, etc)
Overwrite the css background-image https://github.com/scttcper/ngx-toastr/blob/master/src/lib/toastr.css - How do I use this in an ErrorHandler? See: scttcper#179
