Easy, Reusable Animation Utility library for Angular Apps.
Angular Animations utility library is a collection of reusable and parametrized animations build for Angular 4.4.6+ that can be used in a declarative manner. It implements all animations from [animate.css](https://daneden.github.io/animate.css/) (and more). Works both with AOT and JIT compilations.

## Getting Started
### Prerequisites
Make sure you import `BrowserAnimationModule` in your angular app.
```bash
npm i @angular/animations@latest --save
```
Import `BrowserAnimationsModule` from `@angular/platform-browser/animations` in your root NgModule
```ts
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
```
```ts
@NgModule({
declarations: [
...
],
imports: [
...
BrowserAnimationsModule
],
})
export class AppModule { }
```
## Installation
```bash
npm i angular-animations --save
```
## Usage
### Animations `on enter` / `on leave`
Animations on enter / on leave are triggered in a moment when element is added to or removed from the dom.
Basic example would be with `*ngIf` template directive.
Import animation functions that you want to use and add them to `animations` in a component decorator:
```ts
import { fadeInOnEnterAnimation, fadeOutOnLeaveAnimation } from 'angular-animations';
@Component({
selector: '...',
templateUrl: '...',
styleUrls: ['...'],
animations: [
fadeInOnEnterAnimation(),
fadeOutOnLeaveAnimation()
]
})
```
and use them in the template:
```html
```
### Animations with state or triggered by state changes
These animations take as an input a boolean value. Some animations, like Attention Seekers are triggered depending on the `direction` parameter; bidirectional (`<=>`) will be triggered by any state change, unidirectional (`=>`) will be triggered only when state changes from false to true.
All `in` and `out` animations are triggered by changes of state from `false` to `true`. Animations that preserve state, like `collapse` or `rotate` display default state when the value is `false` and transition to end state when the value is `true`
```ts
import { collapseAnimation, rubberBandAnimation } from 'angular-animations';
@Component({
...
animations: [
rubberBandAnimation(),
collapseAnimation(),
]
})
```
```html
```
### Parametrized animations
All animations are open for customizations. All of them have parameters: `duration` and `delay`, and if it make sense for an animation, additional ones: `translate`, `degrees` or `scale`.
Parameters can be used either in a component decorator or dynamically in a template.
In a decorator:
```ts
@Component({
...
animations: [
fadeInUpOnEnterAnimation({ anchor: 'enter', duration: 1000, delay: 100, translate: '30px' }),
bounceOutDownOnLeaveAnimation({ anchor: 'leave', duration: 500, delay: 200, translate: '40px' })
]
})
```
```html
```
Animations like Attention Seekers can take a direction parameter (cannot be in template)
```ts
@Component({
...
animations: [
// triggers when STATE changes from false to true
rubberBandAnimation({anchor: 'rubber', direction: '=>', duration: 500})
]
})
```
```html
```
In a template (providing option for dynamic changes):
```ts
@Component({
...
animations: [
fadeInUpOnEnterAnimation({ anchor: 'enter'),
]
})
```
```html
```
With parameters in a template, we can for example achieve staggering animations:
```html
```
### Animation Callbacks
Each animation supports `start` and `done` callbacks to setup hook methods that get called at the start or end of animations.
We can add callbacks with the syntax `(@trigger.start)` or `(@trigger.done)`, where `trigger` is the name of the animation trigger/anchor being used.
```html
```
The callbacks receive an `AnimationEvent` that contains the following properties: `fromState` `phaseName`("start" or "done"), `toState` and `totalTime`
```ts
import { AnimationEvent } from '@angular/animations';
//...
animStart(event: AnimationEvent) {
console.log('Animation Started', event);
}
animDone(event: AnimationEvent) {
console.log('Animation Ended', event);
}
```
You can find more information about Animation callbacks in the [Angular docs](https://angular.io/guide/transition-and-triggers#animation-callbacks)
#### Loop animation
You can achieve looped animation by using `done` callback. Define a variable that triggers animation and toggle it when animation done callback is called:
```html
```
and in the component:
```ts
animState = false;
animDone() {
this.animState = !this.animState
}
```
[Example: simple infinite loop animation](https://stackblitz.com/edit/angular-animations-lib-simple-loop?file=src/app/demo-main/demo-main.component.html)
[Example: repeat animation N times after clicking the button](https://stackblitz.com/edit/angular-animations-lib-simple-loop-repeat-n-times?file=src/app/demo-main/demo-main.component.html)
[Example: repeat animation until certain event occurs](https://stackblitz.com/edit/angular-animations-lib-simple-loop-repeat-until-btn-click?file=src/app/demo-main/demo-main.component.html)
#### Chain animations
You can chain animations (e.g. wait for the first animation to finish before the second one starts) by using the `done` callback.
[Example: OnEnter/OnLeave chained animations](https://stackblitz.com/edit/angular-animations-lib-chained-on-enter?file=src/app/demo-main/demo-main.component.html)
