ngx-toastr

DEMO: https://ngx-toastr.vercel.app ## Features - 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](https://angular.io/docs/ts/latest/guide/animations.html) - Output toasts to an optional target directive ## Dependencies Latest version available for each version of Angular | ngx-toastr | Angular | | ---------- | ----------- | | 13.2.1 | 10.x 11.x | | 14.3.0 | 12.x 13.x | | 15.2.2 | 14.x. | | 16.2.0 | 15.x | | 17.0.2 | 16.x | | current | >= 17.x | ## Install ```bash npm install ngx-toastr --save ``` `@angular/animations` package is a required dependency for the default toast ```bash npm install @angular/animations --save ``` Don't want to use `@angular/animations`? See [Setup Without Animations](#setup-without-animations). ## Setup **step 1:** add css - copy [toast css](/src/lib/toastr.css) to your project. - If you are using sass you can import the css. ```scss // regular style toast @import 'ngx-toastr/toastr'; // bootstrap style toast // or import a bootstrap 4 alert styled design (SASS ONLY) // should be after your bootstrap imports, it uses bs4 variables, mixins, functions @import 'ngx-toastr/toastr-bs4-alert'; // if you'd like to use it without importing all of bootstrap it requires @import 'bootstrap/scss/functions'; @import 'bootstrap/scss/variables'; @import 'bootstrap/scss/mixins'; // bootstrap 4 @import 'ngx-toastr/toastr-bs4-alert'; // boostrap 5 @import 'ngx-toastr/toastr-bs5-alert'; ``` - If you are using angular-cli you can add it to your angular.json ```ts "styles": [ "styles.scss", "node_modules/ngx-toastr/toastr.css" // try adding '../' if you're using angular cli before 6 ] ``` **step 2:** add `ToastrModule` to app `NgModule`, or `provideToastr` to providers, make sure you have `BrowserAnimationsModule` (or `provideAnimations`) as well. - Module based ```typescript 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 {} ``` - Standalone ```typescript import { AppComponent } from './src/app.component'; import { provideAnimations } from '@angular/platform-browser/animations'; import { provideToastr } from 'ngx-toastr'; bootstrapApplication(AppComponent, { providers: [ provideAnimations(), // required animations providers provideToastr(), // Toastr providers ] }); ``` ## Use ```typescript import { ToastrService } from 'ngx-toastr'; @Component({...}) export class YourComponent { constructor(private toastr: ToastrService) {} showSuccess() { this.toastr.success('Hello world!', 'Toastr fun!'); } } ``` ## Options There are **individual options** and **global options**. ### Individual 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 \| 'timeOut' \| 'extendedTimeOut'` | false | Disable both timeOut and extendedTimeOut when set to `true`. Allows specifying which timeOut to disable, either: `timeOut` or `extendedTimeOut` | | easing | string | 'ease-in' | Toast component easing | | easeTime | string \| number | 300 | Time spent easing | | enableHtml | boolean | false | Allow html in message | | newestOnTop | boolean | true | New toast placement | | progressBar | boolean | false | Show progress bar | | progressAnimation | `'decreasing' \| 'increasing'` | 'decreasing' | Changes the animation of the progress bar. | | toastClass | string | 'ngx-toastr' | CSS class(es) for toast | | positionClass | string | 'toast-top-right' | CSS class(es) for toast container | | titleClass | string | 'toast-title' | CSS class(es) for inside toast on title | | messageClass | string | 'toast-message' | CSS class(es) for 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 | #### Setting Individual Options success, error, info, warning take `(message, title, ToastConfig)` pass an options object to replace any default option. ```typescript this.toastrService.error('everything is broken', 'Major Error', { timeOut: 3000, }); ``` ### Global Options All [individual options](#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](#iconclasses-defaults) | Classes used on toastr service methods | | preventDuplicates | boolean | false | Block duplicate messages | | countDuplicates | boolean | false | Displays a duplicates counter (preventDuplicates must be true). Toast must have a title and duplicate message | | resetTimeoutOnDuplicate | boolean | false | Reset toast timeout on duplicate (preventDuplicates must be true) | | includeTitleDuplicates | boolean | false | Include the title of a toast when checking for duplicates (by default only message is compared) | ##### iconClasses defaults ```typescript iconClasses = { error: 'toast-error', info: 'toast-info', success: 'toast-success', warning: 'toast-warning', }; ``` #### Setting Global Options Pass values to `ToastrModule.forRoot()` or `provideToastr()` to set global options. - Module based ```typescript // root app NgModule imports: [ ToastrModule.forRoot({ timeOut: 10000, positionClass: 'toast-bottom-right', preventDuplicates: true, }), ], ``` - Standalone ```typescript import { AppComponent } from './src/app.component'; import { provideAnimations } from '@angular/platform-browser/animations'; import { provideToastr } from 'ngx-toastr'; bootstrapApplication(AppComponent, { providers: [ provideToastr({ timeOut: 10000, positionClass: 'toast-bottom-right', preventDuplicates: true, }), ] }); ``` ### Toastr Service methods return: ```typescript export interface ActiveToast { /** Your Toast ID. Use this to close it individually */ toastId: number; /** the title of your toast. Stored to prevent duplicates if includeTitleDuplicates set */ title: string; /** the message of your toast. Stored to prevent duplicates */ message: string; /** a reference to the component see portal.ts */ portal: ComponentRef; /** a reference to your toast */ toastRef: ToastRef; /** triggered when toast is active */ onShown: Observable; /** triggered when toast is destroyed */ onHidden: Observable; /** triggered on toast click */ onTap: Observable; /** available for your use in custom toast */ onAction: Observable; } ``` ### Put toasts in your own container 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. Make sure that your container has an `aria-live="polite"` attribute, so that any time a toast is injected into the container it is announced by screen readers. ```typescript 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. ```typescript import { Component, OnInit, ViewChild } from '@angular/core'; import { ToastContainerDirective, ToastrService } from 'ngx-toastr'; @Component({ selector: 'app-root', template: `

Click

`, }) export class AppComponent implements OnInit { @ViewChild(ToastContainerDirective, { static: true }) toastContainer: ToastContainerDirective; constructor(private toastrService: ToastrService) {} ngOnInit() { this.toastrService.overlayContainer = this.toastContainer; } onClick() { this.toastrService.success('in div'); } } ``` ## Functions ##### Clear Remove all or a single toast by optional id ```ts toastrService.clear(toastId?: number); ``` ##### Remove Remove and destroy a single toast by id ``` toastrService.remove(toastId: number); ``` ## SystemJS 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`: ```js map: { 'ngx-toastr': 'node_modules/ngx-toastr/bundles/ngx-toastr.umd.min.js', } ``` ## Setup Without Animations 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`) ```typescript import { ToastrModule, ToastNoAnimation, ToastNoAnimationModule } from 'ngx-toastr'; @NgModule({ imports: [ // ... // BrowserAnimationsModule no longer required ToastNoAnimationModule.forRoot(), ], // ... }) class AppModule {} ``` That's it! Animations are no longer required. ## Using A Custom Toast 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 ```typescript import { ToastrModule } from 'ngx-toastr'; @NgModule({ imports: [ ToastrModule.forRoot({ toastComponent: YourToastComponent, // added custom toast! }), ], bootstrap: [App], declarations: [App, YourToastComponent], // add! }) class AppModule {} ``` ## FAQ 1. ExpressionChangedAfterItHasBeenCheckedError: Expression has changed after it was checked\ When opening a toast inside an angular lifecycle wrap it in setTimeout ```typescript ngOnInit() { setTimeout(() => this.toastr.success('sup')) } ``` 2. Change default icons (check, warning sign, etc)\ Overwrite the css background-image: https://github.com/scttcper/ngx-toastr/blob/master/src/lib/toastr.css. 3. How do I use this in an ErrorHandler?\ See: https://github.com/scttcper/ngx-toastr/issues/179. 4. How can I translate messages?\ See: https://github.com/scttcper/ngx-toastr/issues/201. 5. How to handle toastr click/tap action? ```ts showToaster() { this.toastr.success('Hello world!', 'Toastr fun!') .onTap .pipe(take(1)) .subscribe(() => this.toasterClickedHandler()); } toasterClickedHandler() { console.log('Toastr clicked'); } ``` 6. How to customize styling without overridding defaults?\ Add multiple CSS classes separated by a space: ```ts toastClass: 'yourclass ngx-toastr' ``` See: https://github.com/scttcper/ngx-toastr/issues/594. ## Previous Works [toastr](https://github.com/CodeSeven/toastr) original toastr\ [angular-toastr](https://github.com/Foxandxss/angular-toastr) AngularJS toastr\ [notyf](https://github.com/caroso1222/notyf) notyf (css) ## License MIT --- > GitHub [@scttcper](https://github.com/scttcper) · > Twitter [@scttcper](https://twitter.com/scttcper)
