Built With Stencil Maintenance NPM version Downloads TotalDownloads Twitter Follow


Web Component built with Stencil.js to use Web Animations API in a declarative way. You can animate any HTML element easily:

  <h1>Hello World</h1>

As you can see it's like Animate.css but with superpowers because you can keep the last state (opacity, transform, etc) of a previous animation before to create another one.

To animate things you can use the createAnimatableComponent utility.

import {
} from '@proyecto26/animatable-component';

const SendMessageButton = (props) =>(
  <ion-fab-button {...props}>
    <ion-icon name='send' />
const AnimatableSendMessageButton = createAnimatableComponent(SendMessageButton);
const keyFramesSendMessage: Keyframe[] = [
    opacity: '0',
    transform: 'rotate(0deg)'
    opacity: '1',
    transform: 'rotate(360deg)'
const optionsSendMessage: KeyframeAnimationOptions = {
  duration: 500,
  easing: 'ease-in-out'

  render() {
    return (
        onFinish={() => alert('Eureka!')}

Using this component

Script tag

  • Put a script tag similar to this <script src=''></script> in the head of your index.html
  • Then you can use the element anywhere in your template, JSX, html etc

Node Modules

  • Run npm install @proyecto26/animatable-component --save
  • Put a script tag similar to this <script src='node_modules/@proyecto26/animatable-component/dist/animatable-component.js'></script> in the head of your index.html
  • Then you can use the element anywhere in your template, JSX, html etc

In a stencil-starter app

  • Run npm install @proyecto26/animatable-component --save
  • Add an import to the npm packages import @proyecto26/animatable-component;
  • Then you can use the element anywhere in your template, JSX, html etc

Framework integrations


Using animatable-component component within an Angular project:

Including the Custom Elements Schema

Including the CUSTOM_ELEMENTS_SCHEMA in the module allows the use of Web Components in the HTML files. Here is an example of adding it to AppModule:

import { BrowserModule } from '@angular/platform-browser';
import { CUSTOM_ELEMENTS_SCHEMA, NgModule } from '@angular/core';
import { AppComponent } from './app.component';
  declarations: [AppComponent],
  imports: [BrowserModule],
  bootstrap: [AppComponent],
export class AppModule {}

The CUSTOM_ELEMENTS_SCHEMA needs to be included in any module that uses Animatable.

Calling defineCustomElements

Animatable component includes a function used to load itself in the application window object. That function is called defineCustomElements() and needs to be executed once during the bootstrapping of your application. One convenient place to add it is in the main.ts file as follows:

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { defineCustomElements as defineAnimatable } from '@proyecto26/animatable-component/loader';
import { AppModule } from './app/app.module';
import { environment } from './environments/environment';
if (environment.production) {
  .catch(err => console.log(err));

from stencil documentation


import React from 'react'
import ReactDOM from 'react-dom'
import { defineCustomElements as defineAnimatable } from '@proyecto26/animatable-component/loader'
import App from './App';
ReactDOM.render(<App />, document.getElementById('root'));

from stencil documentation


In order to use the animatable-component Web Component inside of a Vue application, it should be modified to define the custom elements and to inform the Vue compiler which elements to ignore during compilation. This can all be done within the main.js file as follows:

import Vue from 'vue';
import { defineCustomElements as defineAnimatable } from '@proyecto26/animatable-component/loader'
import App from './App.vue';
Vue.config.productionTip = false;
Vue.config.ignoredElements = [/animatable-\w*/];
// Bind the custom element to the window object
new Vue({
  render: h => h(App)
