Emotional

Emotion Animation Library is an animation library that allows the creation of complex animations with React that use dynamically changing props using Emotion.

API

There are two main APIs

1. Animate: Class. Use one or more of the existing animation presets.
2. useAnimate(): React Hook. Create a custom animation using the existing presets or scaffold a completely new animation. This is powerful as this can be used to create a Wrapper component

Class: Animate

• name <string | string[]> One or more presets

To use one of the presets, simply use:

import { Animate } from 'emotionaljs';

const { animation } = new Animation('fadeIn');

const StyledTooltip = styled(Button)({ theme }) => ({
    display: 'relative',

    '& > .Button:hover': {
        animation
    }
})

To use multiple presets, chain them as follows:

import { Animate } from 'emotionaljs';

const { animation } = new Animation('fadeIn', 'fadeOut');

const StyledTooltip = styled(Button)({ theme }) => ({
    display: 'relative',

    '& > .Button:hover': {
        animation
    }
})

Hook: useAnimate

import { useAnimate } from 'emotionaljs';

const animation =  useAnimate({
    enter: 'fadeIn',
    enterFrom: undefined,
    enterTo: undefined,
    enterDuration: 0.2, // in seconds
    enterTimingFunction: 'ease-in-out',
    enterDelay: 0, // in seconds
    enterFillMode: 'forwards',
    enterDirection: 'reverse',
    enterIterationCount: 1,
    exit: 'fadeOut',
    exitFrom: undefined,
    exitTo: undefined,
    exitDuration: 0.2, // in seconds
    exitTimingFunction: 'cubic-bezier(0.25, 0.1, 0.25, 1)'
    exitDelay: 0, // in seconds
    exitFillMode: 'forwards',
    exitDirection: 'reverse',
    exitIterationCount: 1,
 })

Design Patterns

• Using with CSS-in-JS
• Chaining animations with pre-built presets
• Complex custom animations
• Using as a Wrapper Component
