Easy methods to Use Angular Native Animations

The trendy net is shifting in the direction of extremely intuitive interfaces and wealthy graphical content material to maintain customers glued to their gadgets. Animations turn out to be useful when making net functions that stand out from the remaining.

As a key participant within the front-end growth world, Angular ships with net animation assist. Right here’s every part you must know to incorporate animation in Angular functions!

Getting began

Angular animations are constructed on prime of the native Internet Animations API, making it simpler to run throughout each Android and iOS platforms. Put merely, as builders, we won’t be tied solely to the online browser implementation.

In animation, there are totally different states throughout every part of the animation life cycle. This idea is frequent for Angular animations too.

You need to be acquainted with these three states and the way they’re outlined when utilizing animations powered by Angular:

  • Customized state: We will present a customized identify to a selected state and use that identify when implementing the animation.
  • Wildcard state: That is the frequent state of a component. It is usually recognized to be the default state.
  • Void state: The state during which the component shouldn’t be a part of the DOM. That is the state the place the component shouldn’t be but rendered or has already left the view.

Angular animations in follow

To kick off our Angular animations journey, add BrowserAnimationsModule as an import to the app.module.ts file.

import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

  imports: [BrowserAnimationsModule]

Now, implement animations inside parts by importing particular animation features from @angular/animations. A number of the generally used animation features are a set off, state, fashion, animate, and transition.

import { set off, state, fashion, animate, transition } from '@angular/animations';

Subsequent, outline the animations throughout the animations: metadata property contained in the @Element() decorator of a element.

  selector: 'app-animation-test',
  templateUrl: './animation-test.element.html',
  styleUrls: ['./animation-test.component.css'],
  animations: [
      //animation implementation

Animated to-do record

Now that we’ve got arrange the atmosphere with all of the conditions, it’s time to see Angular animations in motion. Let’s develop the next animated to-do record.

Angular animated to-do listOn this easy undertaking, the to-do gadgets will slide in when the Add button is clicked and slide out on clicking the Delete button. The next easy code block is chargeable for this animation impact.

animations: [
    trigger('addItem', [
      state('void', style({
        transform: 'translateX(-100%)'
      transition('void <=> *', animate('0.5s ease-in'))

There are numerous helper strategies which are important when animating utilizing Angular, so let’s look into their utilization.

Angular animation helper strategies

set off()

The general implementation of a single animation goes contained in the set off() methodology. A set off ought to have a reputation that may be referenced from the DOM. Within the above instance, we’ve got outlined a set off named addItem, and will probably be hooked up to the DOM component as follows.

<div @addItem></div>


The tactic state() defines totally different states that ought to be achieved on the finish of an animation. The state could be any of the three states: customized, wildcard (*), or void. Contained in the state() methodology, outline the kinds related to every state.

state('begin', fashion({ backgroundColor: 'yellow' })),

On this snippet, we’ve got outlined a state named begin and utilized a yellow background coloration when that state is achieved.


We will use this methodology inside different strategies like state() and transition() to use totally different kinds. The fashion() methodology will take an object of CSS properties.

fashion({ backgroundColor: 'yellow', opacity:0 })


The transition() methodology defines the transition from one state to a different. The primary argument of this methodology defines how the states ought to change. For instance, * => void refers back to the situation the place a component is faraway from the DOM. Equally, <=> says that the animation could be utilized in each instructions.

The next are some examples of state change expressions:

  • void => *: Ingredient adjustments from void state to some other state.
  • preliminary => closing: State adjustments from preliminary to closing.
  • void <=> *: State adjustments from void to wildcard state and vice versa.

The second argument defines the timing properties for animation utilizing the animate() methodology.


The animate() methodology takes in timing properties like length, delay, and easing. This methodology is crucial for an animation to be full. The syntax of the animate() methodology will look as follows.

animate ('length delay easing')

Now that we’ve got a greater concept of how animation helpers work, let’s go forward and full the to-do record animation. However first, add the next TypeScript code to finish the performance of the buttons.

gadgets = [
    'Go To School',
    'Buy Grocery',
    'Workout 1 hour'

itemList: string[] = [];
depend = 0;

addItem() {
  if (this.gadgets.size > this.depend) {

removeItem() {
  if(this.depend > 0) {

Then, design the template utilizing the next HTML block. Bear in mind so as to add Bootstrap for the styling.

<div class="container pt-5">
  <h1>To Do Listing</h1>
  <button (click on)="addItem()" class="btn btn-success">Add</button>
  <button (click on)="removeItem()" class="btn btn-danger">Delete</button>
  <div class="card" *ngFor="let record of itemList" @addItem>{{record}}</div>

Different approaches

Aside from the above implementation, there are a number of approaches that we will use to attain the identical outcome. Let’s check out some different strategies to implement the identical animation simply to get extra acquainted with Angular animations.

Utilizing transitions

We will keep away from utilizing the state() methodology and implement the identical conduct utilizing the transition() methodology. Within the following code instance, we use two transition() strategies and outline the fashion earlier than and after the transition.

animations: [
    trigger('addItem', [
      transition('void => *', [
        style({ transform: 'translateX(-100%)' }),
        animate('0.5s ease-in')
      transition('* => void', [
        animate('0.5s ease-in', style({ transform: 'translateX(-100%)' }))

Utilizing aliases

Since void =>* and * => void are frequent situations, Angular supplies :enter and :go away aliases to deal with animations of parts getting into and leaving the DOM. Discuss with the next code instance.

animations: [
    trigger('addItem', [
      transition(':enter', [
        style({ transform: 'translateX(-100%)' }),
        animate('0.5s ease-in')
      transition(':go away', [
        animate('0.5s ease-in', style({ transform: 'translateX(-100%)' }))

Utilizing customized states

We will additionally obtain the identical outcome utilizing customized states. Let’s introduce a state named preliminary as a substitute of the wildcard state.

animations: [
    trigger('addItem', [
      state('void', style({
        transform: 'translateX(-100%)'
      transition('void <=> initial', animate('0.5s ease-in'))

When utilizing customized states, we must always bind them to the component. To do that, first declare a variable contained in the element.

initialState = ‘preliminary’;

Then, bind the state to the template as follows.

<div [@addItem]=initialState></div>


Animations create a greater person expertise by offering interactive interfaces. Angular supplies you with a strong software to develop engaging animations.
