This package was created out of the need for using CSS animations with a library like animate.css in Angular2 when there was no useful animation builder available yet.
css-animator works with any JavaScript application and takes the pain out of applying CSS animations manually. It also takes care of positioning elements that are being animated, among other useful things.
Feel free to open an issue if you're experiencing issues, or if you have any suggestions or comments.
The package includes ES5 compiled files, alongside TypeScript typings and source maps. Also UMD bundle files are included.

Question: Other elements jump around during animation or after showing/hiding
Answer: Try to change the pin and useVisibility options (and have a look at all the other customization options)
animator.pin = false;
animator.useVisibility = true;You can install css-animator from npm or use one of the available UMD bundles.
$ yarn add css-animator$ npm install --save css-animator$ jspm install npm:css-animatorName (to require) |

A very basic example can be found in the docs/ folder, which is also hosted on GitHub Pages: https://fabiandev.github.io/css-animator/
Use this package in combination with CSS animations.
A library like animate.css already offers a lot of great animations out of the box.
You can install both packages by running:
$ yarn add css-animator animate.cssYou can use css-animator without Angular2. Just import the class and animate any HTMLElement.
import { AnimationBuilder } from 'css-animator/builder';
let animator = new AnimationBuilder();
animator.setType('shake').animate(element);Want to know when an animation has finished? The AnimationBuilder instance returns a promise:
animator
.setType('shake')
.animate(element)
.then(() => {
// Animation finished
})
.catch(() => {
// Animation interrupted
});You may also change the default options for every instance that is created once changed:
import { AnimationBuilder } from 'css-animator/builder';
AnimationBuilder.defaults.pin = false;
AnimationBuilder.defaults.useVisibility = true;Note: changing
pinanduseVisibilitymay be the way to go if you have issues with the possition of other elements during animation
Before getting started and to make use of the directive and the service provided by css-animator, you have to import its module:
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { AnimatorModule } from 'css-animator';
@NgModule({
imports: [
BrowserModule,
AnimatorModule
],
declarations: [
AppComponent
],
bootstrap: [
AppComponent
],
})
export class AppModule { }There is a little Angular2 service included, that gives you the power of dependency injection out of the box.
import { Component, OnInit } from '@angular/core';
import { AnimationService, AnimationBuilder } from 'css-animator';
@Component({ ... })
export class SomeComponent implements OnInit {
private animator: AnimationBuilder;
constructor(animationService: AnimationService, private elementRef: ElementRef) {
this.animator = animationService.builder();
}
ngOnInit() {
this.animator.setType('fadeInUp').show(this.elementRef.nativeElement);
}
}Feel free to create your own directive around css-animator. For you to get started, there is one included in this package.
import { Component } from '@angular/core';
@Component({
selector: 'my-app',
template: `
<div animates #animation="animates">
<span (click)="animation.start({type: 'bounce'})">Click me!</span>
</div>
`
})
export class AppComponent {
}It is possible to default options on the element, that will be used if you call animation.start().
You can pass any option that the interface AnimationOptions supports like this: animation.start({type: 'bounce', duration: 800}).
<div
animates
#animation="animates"
animates="{ type: 'wobble', duration: '2000' }" // default options are optional
animatesInitMode="show" // Can be used with [animatesOnInit] for "show" or "hide"
[animatesOnInit]="{ type: 'fadeInUp' }" // automatically animate on init (optional)
(click)="animation.start()"
(mouseleave)="animation.pause()"
(mouseenter)="animation.resume()"
>
</div>You can also animate host elements with css-animator!
Below are all options supported by css-animator. You may notice, that all CSS animation properties are included, so you can look up which values are supported, where the options delay and duration have to be set as numbers in ms (e.g. 1000 for one second).
The animation-name is currently not supported, as type is as set as class.
export interface AnimationOptions {
// General settings:
disabled?: boolean;
fixed?: boolean;
reject?: boolean;
useVisibility?: boolean;
pin?: boolean;
// Animation type set as class:
type?: string;
// Animation settings:
fillMode?: string;
timingFunction?: string;
playState?: string;
direction?: string;
duration?: number;
delay?: number;
iterationCount?: number|string;
}The
delayoption is an exception and won't be set as CSS animation property, as delays are handled via JavaScript timeouts. If you really want to use the CSS rule, you can callapplyDelayAsStyleto apply the delay immediately on the element.
You can change the options on an AnimationBuilder instance in three different ways.
You can also change the defaults for future instances.
import { AnimationBuilder } from 'css-animator/builder';
AnimationBuilder.defaults.type = 'bounce';
AnimationBuilder.defaults.duration = '1500';
let animator = new AnimationBuilder();Changing the defaults won't affect instances, that have already been created.
animator
.setType('bounce')
.setDuration(1500);animator.type = 'bounce';
if (animator.duration < 1500) {
animator.duration = 1500;
}animator.setOptions({
type: 'bounce',
duration: 1500
});You can apply options, that are related to the animation itself.
Supported options are: fillMode, timingFunction, playState,
direction, duration and iterationCount.
Settings that are applied are immediately set on the element, without the need for starting an animation or saving them on the instance. css-animator can't take care of resetting the element though, so be careful with this feature.
animator
.applyIterationCount(element, 3);You can also save a value and apply it afterwards:
animator
.setIterationCount(3)
.applyIterationCount(element);Setting this option to true on an AnimationBuilder instance bypasses animations and shows or hides an element immediately, while skipping animations entirely. It is also possible to disable animations for all instances by changing the global value:
import { AnimationBuilder } from 'css-animator/builder';
AnimationBuilder.disabled = true;As mentioned above, elements being animated are positioned absolute. If you want to change
the position mode to fixed, set the fixed option to true.
Setting this option to true results in a more accurate positioning, as
css-animatorwon't round to the nearest full pixel (integer instead of float). But keep in mind, that you might experience unexpected behavior when scrolling while an element is being animated.
The promise for an animation is rejected with animation_aborted, if it is interrupted somehow. To change
this behavior, set the reject option to false.
AnimationBuilder uses the hidden attribute on elements to hide them. If you want to use the visibility CSS rule,
set useVisibility to true.
By default, an element will be positioned absolute while animating, to enable concurrent animations.
Also the relative position (top and left) will be calculated and set on the element and the margin is set to 0px.
Furthermore the element's calculated width and height will be set explicitly.
If you want css-animator to only apply the animation, without changing the element's style temporarily, set pin to false.
The class that will be applied to the element alongside animated and animated-show, if the element is being shown, or animated-hide, if the element is being hidden.
Set the animation duration as integer in ms.
Set a delay, before the animation should start as integer in ms.
animate(element: HTMLElement, mode = AnimationMode.Animate): Promise<HTMLElement>Simply animate an element.
show(element: HTMLElement): Promise<HTMLElement>Animate an element, that was previously hidden.
Calling show is equivalent to:
import { AnimationMode } from 'css-animator/builder';
animator.animate(element, AnimationMode.Show);hide(element: HTMLElement): Promise<HTMLElement>Adds the attribute hidden to the element after the animation has finished.
You may need to add something like [hidden] { display: none; } to your CSS.
Again you can also use the animate function by passing AnimationMode.Hide.
stop(element: HTMLElement, reset = true): Promise<HTMLElement>Stop the current animation on an element, reset it's position, reject the promise and remove the event listener that listens for animation end.
setOptions(options: AnimationOptions): AnimationBuilderSet multiple options at once.
set{Option}(option: string|number|boolean): AnimationBuilderYou may set options individually like setDuration(500)
addAnimationClass(name: string): AnimationBuilderAdds your custom classes while animating alongside the classes animated animated-{mode} (where mode is show, hide or default, unless you pass another string to the animate method).
removeAnimationClass(name: string): AnimationBuilderWon't add classes for future animations, previously added with addAnimationClass.
You can also directly apply options without saving it to the animation builder by using
apply{Option}(options: string|number)
Also there are getters and setters for each option, you can access withanimator.{option}.
reset(element: HTMLElement, removePending = true, rejectTimeouts = false, rejectListeners = false): voiddispose(): voidRemoves all elements, timeouts and listeners. Call if you don't want to use the builder anymore:
let animator = new AnimationBuilder();
animator.dispose();
animator = null;start(options?: AnimationOptions): Promise<HTMLElement>Animates the element.
show(options?: AnimationOptions): Promise<HTMLElement>Shows an element that was hidden.
hide(options?: AnimationOptions): Promise<HTMLElement>Hides an element by adding the attribute hidden to the element after the animation has finished.
You may need to add something like [hidden] { display: none; } to your CSS.
stop(): voidStops the current animation on an element, resets it's position, and removes the event listener that listens for animation end.
startOrStop(options?: AnimationOptions)Calls start if the element was already started and stop otherwise.
pause(): voidPauses the animation (sets the playState option to paused).
resume(): voidResumes a previously paused animation (sets the playState option to running).
toggle(): voidSwitches between pause() and resume().
