## 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     |
| ---------- | ----------- |
| 11.3.3     | 8.x         |
| 12.1.0     | 9.x         |
| 13.2.1     | 10.x 11.x   |
| 14.3.0     | 12.x 13.x   |
| 15.2.2     | 14.x.       |
| 16.2.0     | 15.x        |
| current    | >= 16.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

#### 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<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 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: `
    <h1><a (click)="onClick()">Click</a></h1>
    <div aria-live="polite" toastContainer></div>
  `,
})
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.
