Installation

Just paste npm install text-animation-js in the console.

How to use it

Just import the component and pass a HTML element to it.

import Animation from "text-animation-js";

const animation = new Animation(document.querySelector("p"));

Call new Animation() will return an animation instance.

Also you need to import the css styles:

import "text-animation-js/styles.css";

Animation

Configuration

Animation accepts two parameters, a HTML element and callback that will be called on animation end.

Methods

Each Animation instance has three methods play, pause, and reset:

Play

Call animation.play() will start the animation, it returns the animation instance.

document.querySelector("button").addEventListener("click", () => {
  animation.play();
});

This will start the animation when the button is clicked.

Pause

Call animation.pause() will pause the animation, it returns the animation instance.

document.querySelector("button").addEventListener("click", () => {
  animation.pause();
});

This will pause the animation when the button is clicked.

Reset

Call animation.reset() will reset the animation, it returns the animation instance.

document.querySelector("button").addEventListener("click", () => {
  animation.reset();
});

This will reset the animation when the button is clicked.

Controlling multiple animations

This is a helper to control multiple animations with one call.

Configuration

AnimationList accepts one parameter, an Animation array, this will be the animations to control.

const animations = [
  new Animation(element1),
  new Animation(element2),
  new Animation(element3),
];

const animationList = new AnimationList(animations);

Methods

Each AnimationList instance has three methods play, pause, and reset:

Play

Call animationList.play() will start the animations, it will wait for each animation to finish before starting the next one.

document.querySelector("button").addEventListener("click", () => {
  animationList.play();
});

Pause

Call animationList.pause() will pause all the animations.

document.querySelector("button").addEventListener("click", () => {
  animationList.pause();
});

Reset

Call animationList.reset() will reset all the animations.

document.querySelector("button").addEventListener("click", () => {
  animationList.reset();
});

Demos

TODO

• [ ] animaciones personalizadas
• [ ] unit testing?

Issues

• [ ] callback hell, Animation.play solo agrega callbacks, hay que limpiarlos después de lanzárlos
• [ ] AnimationList pause no funciona justo al final de la transición
